    Three-level DC/DC converter topology and sliding-mode control method
    J.Renes Pinheiro, in 1992 made a zero-voltage-switching three-level DC/DC converters [1], the stress for the input DC voltage converter switch one-second, ideal for high input voltage, output power applications. Therefore, three-level DC/DC converter has attracted widespread attention, and have seen significant development. At present, the three-level technology in existing in the DC/DC converter, have got a very good application. Part three-level DC/DC converters reduce the switching of stress at the same time, also significantly reduces the volume of the filter, improved converter's dynamic characteristics. Application of three-level technology, fully embodies the "using Active control method reduces the volume of passive components" academic thought.


    23 level the derivation and development of DC/DC converter topology
    2.1 three-level two switching unit
    [2] the derivation process of analysis for three-level PWM DC/DC converters: 1 replaced by 2 switching valve in-line switch pipes to reduce voltage stress and JVC BN-VF733U Battery Charger introduce 1 clamp diodes and clamping voltage source (it is divided into two equal to the voltage source) ensure balanced 2 switch voltage stress. Circuit switching tubes in different locations, the voltage clamp and clamp diode method is different. Extract 2 units of three-level switch as shown in Figure 1. Figure 1 (a), the clamping diode anode and clamping voltage source connected to the midpoint, called anode units; figure 1 (b), the clamping diode cathode connected to the midpoint of the clamping voltage source, called the cathode.
    2.2 six non-isolated three-level DC/DC converter
    Three level DC/DC transform device of derivation process can summary for following three a steps: a is will basic transform device of switch tube replace for mutual series of 2 only switch tube; II is looking for or constitute clamp bit voltage source; three is from clamp bit voltage source of midpoint introduced 1 only clamp bit diode to mutual series of 2 only switch tube of midpoint, clamp bit diode of placed and 2 only switch tube and clamp bit voltage source joins of local about.
    In order to ensure that equal 2 switch voltage stress of pipe, three-level DC/DC converters may be shown in Figure 1 consists of two switches together. [2] the analysis of derivation of half-bridge three-level DC/DC converter, can be extended to all of the DC-DC converter, which has raised a family of three-level DC/DC converter topologies, including Buck,Boost,Buck? Boost,Cuk,Sepic,Zeta 6 non-isolated three-level DC/DC converter, but these 6 kinds of non-isolated three-level input and output DC/DC converters are not common, this shortcoming limiting the scope of their use.

    [10] proposed the introduction of capacitance to the input and output do not total non-isolated three-level DC/DC converters, and improvement of converter structure, its input and output a total of. Improved before the converter keeps the improvement of converter all the advantages, namely: switch voltage stress for the input voltage of the tube one-second; can greatly reduce the energy storage components parameters; continued flow diode voltage stress for the input voltage one-second. Figure 2 shows the total 6 kinds of input and output for non-isolated three-level DC/DC converter.

    Similarly, the Forward,Flyback,Push-Pull can be drawn, half-bridge and full-bridge three-level DC/DC converter isolation [2], as shown in Figure 3.

    33-level selection of filter parameters in DC/DC converter
    6 of these three levels for non-isolated DC/DC converters, and full-bridge three-level DC/DC converter can be three-level output waveform, which greatly reduces the filter parameters of the component. Literature [3,4] detailed analysis of a class of hybrid zero-voltage zero-current switching full-bridge three-level DC/DC converter, Rectifier high frequency AC voltage in the output of the converter component is very small, can reduce the output filter, improving the dynamic performance of converter; both its input current ripple is very small, you can decrease the input filter.
    Following Buck three-level DC/DC converter in the Buck converter and the traditional parameters of filter design as an example for comparison. Figure 4 shows that Buck three-level maximum amount of fluctuation of DC/DC converter with inductor current is one-fourth of a Buck converter. If the inductor Nikon Coolpix S700 Battery Charger current fluctuation of the two maximum values are the same, so Buck three-level DC/DC converter filter inductance can be reduced to Buck converter filter inductance one-fourth.
    4BuckTL converter with inductor for Buck converter with inductor one-fourth
    When designing a power supply, the output ripple size restrictions are clearly and, accordingly, you can calculate the size of the output filter capacitor. After analysis, if the inductor current fluctuation the same, Buck three-level DC/DC Converter output filter capacitor discharge rate increases 1 time Buck converter, so the filtering capacitor can reduce the filtering capacity of one-second Buck converter. Taking into account the influence of parasitic capacitance parameter, filter values to appropriate amplification of capacitance, and the use of smaller-capacity capacitor in parallel to reduce the equivalent series resistance (ESR).
    4 sliding mode control of three-level DC/DC converter application
    In practice, because switching more than a three-level DC/DC converter, control is relatively complex, on the control method of research is still in its early stages. Three-level DC/DC converters with multiple modes, and each mode has its own equation of State, to be carried out on the three-level DC/DC converter system analysis more difficult. At present, the three-level DC/DC converter using pulse-width modulation (PWM) and cross-combination of control methods. PWM control with its inherent defects, however, that its performance depends on system parameters. When the system is subjected to transient or persistent disturbances, also changes the parameters of the system, even a parameter does not match the situation, this performance will be greatly reduced.
    In order to enhance and improve the stability of three-level DC/DC converter, load disturbances and resistance parameter perturbations, of fast, modern control theory such as adaptive control, nonlinear feedback linearization control, sliding mode variable structure control, optimal control and fuzzy control, neural networks and intelligent control in the application of three-level DC/DC converter study will also be carried out step by step. But literature has not yet been dealt with.
    Where variable structure control with sliding mode in power electronic system to improve robustness, dynamic quality, control design of hardware circuit had achieved some results, such as [8,9]. Variable structure control with sliding mode control is essentially a, and it's big advantage is its performance does not depend on system control parameters. [8] details the sliding mode variable structure control for DC/DC JVC AA-V16 Battery Charger converters, discusses how to use the equivalent control as a means of analysis to analysis of Buck,Boost,Buck? Boost converter, this method ensures that the system under large-signal and small-signal stability.
    For three-level PWM DC/DC converter, because of its unique multimode, very suitable for using sliding mode variable structure control to achieve and improve the converter's dynamic performance and robustness. Figure 5 shows the Buck three-level DC/DC converter experimental schematic diagram, Figure 6 shows the Buck? Boost three-level DC/DC converter experimental schematic diagram. Sliding mode control for simple hardware circuit, theoretically infinitely high switching frequency, but the actual frequency of switching device restrictions, requirements in sliding-mode control signal outputs plus a delay control links, generally use the Schmitt trigger to achieve. 400Hz drive and load disturbance signal is used to implement input voltage disturbances, to verify that the robust sliding-mode control for both disturbance characteristics.
    Figure 5 is based on sliding mode control for Buck three-level DC/DC converter experimental schematic diagram
    Figure 6 based on sliding mode control for Buck? Boost three-level DC/DC converter experimental schematic diagram
    However, as the number of three-level DC/DC converter the switch more than, of {0,1} is no longer a simple scalar control, choice and selection of control law of sliding surface caused certain difficulties. Research in this area, authors will be in another article for further exploration.

    Characteristics and application of integrated voltage regulator TL499AC

    Now widely used is divided into linear series negative feedback regulator of regulated power supply and switching power supplies, regulators the two types have their own characteristics, usually to make single-chip voltage regulator integrated circuits, respectively, but integrated regulator TL499AC unique is that it also has adjustable linear regulator in series and step-up type switching regulator circuit for two complete. The integrated circuit in addition to sampling for external feedback resistor (used to adjust the output voltage) and outside the small number of components such as inductors, capacitors, two types are integrated in other parts of the regulator must, therefore, very easy to use. The main characteristics and properties of the parameters are as follows:

    -Line voltage input range is 4.5~32V;

    Switching regulator input range 1.1~10V;

    Adjustable output voltage of 2.9~30V;

    When an in-line regulator for lost voltage regulator input voltage is too low when switching regulator will automatically work under the conditions of a standby power supply ensures that the power supply will not be interrupted.

    Interior over-current, over-voltage, overheat protection, with very high reliability.

    2. internal structure and function of TL499AC
    TL499AC is the in-line regulator combination and switching regulator with an 8-foot made of monolithic integrated circuit in the dual in-line package, pin arrangement as shown in Figure 1, function block diagram is shown in Figure 2. TL499AC internal circuit is divided into two parts: one is by the A2 and its related circuits series regulated power supply section. Second is by A1 and related circuit constitute boost type switch regulator power part, which T1 mainly switch tube, T2 is T1 of mirror current detection tube, due to T2 of launches very current and T1 of launches very current into ratio (ratio coefficient by two tube of launches very resistance decided), so available measurement T2 launches very current (voltage) of method indirect monitoring main switch tube T1 of work current to implementation had flow  Panasonic PV-GS320 Battery Charger protection. Because in-line regulator and switching regulators share a feedback and output ends, so the two regulators cannot work under normal circumstances. Can be seen from Figure 2, due to the presence of E1, and both regulators and E2 share a base voltage and with a feedback network, when the normal in-line regulator outputs to be slightly higher than the output voltage switching regulator, its differential output voltage of about 2%. Therefore, when an in-line regulator and switching regulator when the input voltage, as in-line regulator's output voltage is higher than the output voltage switching regulator, thus forcing the switching regulator is in hibernation, micro-level current switching regulator part consumes. Once in-line regulator input voltage due to power failures and other reasons down to when not enough to maintain a stable output voltage, switching regulators will take over on their own work, this characteristic makes it ideally suited for production of DC circuit an uninterruptible power supply.

    3. maximum rated parameters TL499AC
    In-line regulator input voltage: 35V;

    Switching regulator input voltage: 10V;

    Built-in switch control/isolation diode current: 1A

    Total continuous power consumption: TA ≤ 25 ° c: 1W;

    TA>25 c: Derating factor: 8mW/° c;

    Operating ambient temperature range:-20 ¡æ ~85 ¡æ;

    Storage temperature range:-65 ¡æ ~150 ¡æ.
    4. the typical application circuit
    Consists of TL499AC the actual voltage-stabilizing circuit shown in Figure 3. In the circuit, VCC (the voltage is usually obtained by AC rectifier, filter) series to the load power supply regulator, so normal VCC should be at least higher than the output voltage is 2V. E the standby power supply, uninterruptible power supply circuit is required for rechargeable batteries, when the normal AC power supply to trickle charging (Figure 3 in the circuit, TL499AC 1, 3 feet between a resistance). When power switch power supply immediately started their own standby power to the load power.

    In Figure 3 the range of components, see table 1. Series regulator of the maximum output current is 100mA (within limits), switching regulators not only maximum output current and input and JVC BN-VF733U Battery Charger output voltage relative to the size of, and R1 is relative to the size, size of the resistance of the resistor directly affects the maximum operating current of the switch tube, greater resistance, maximum operating current of the switch tube the smaller, hence smaller load current capability. Specific parameters as listed in table 2. Output current IO values in table 2 when the corresponding R1=150 w/1000 ω value in mA.

    According to the TL499AC property, the application circuits particularly suitable in the following situations:

    (1) require power. As power outages of the storage data in the computer system and data acquisition card for removable.

    (2) require higher power supply voltage, but the current small portable electronic products. For example plug-in digital multimeter AC and DC dual-use, use this circuit to eliminate regular replacement battery troubles.

    (3) the requirement of high and low voltage power supply. For example, a portable radio with digital tuning your battery direct supply low voltage amplifier portion of the radio, and the step-up voltage (12V) for use in digital tuner.

    5. usage considerations
    Have some electromagnetic radiation interference due to the switching regulator when working, therefore, for demanding applications where the regulator part should shield (this is especially important for radio equipment). Should be designed to power the circuit board and small signal most of th Nikon Coolpix S700 Battery Charger e distance of the right open, ground wire should be a separate line, inductance l is the best overall small magnetic ring to wear around.

    In less demanding, the capacitor C1 in Figure 3 saves, but the dynamic performance of the circuit will decline, output voltage ripple is also slightly increased. R1 value of not less than 150 ω, otherwise, likely due to the switching valve overcurrent protection value is set too high and causing the failure or damage to the internal switch protection pipe.

    Series voltage regulator input, output voltage greater than to 8V, maximum output current will adjust the drop tube power limitations. In addition, if the series regulator of load current is greater than the current capacity, the output voltage drops will appear in-line regulator and the phenomenon of switching regulators working together, and this may cause integrated circuit temperature is too high, so that the circuit is not working properly.

    Analysis of solar air conditioning works

    Solar cooling is the use of solar collectors required for the provision of the generator for absorption refrigerator heat medium water. Higher heat medium water temperature, refrigerator coefficient of performance (COP), the higher the higher the cooling efficiency of the air conditioning system are. For example, if the heat medium water temperature around 60 ° c, the chiller COP some 0~40; about heat medium water temperature 90 ¡æ, chiller COP some 0~70; about heat medium water temperature 120 ¡æ, COP reaches more than 110 of the refrigerator. Practice has proved that using heat pipe vacuum tube solar collector with a combination of lithium-bromide absorption-type refrigerating machine of solar air conditioning technology program is successful, it is solar energy heat utilization technology has opened up a new field of applications.

    1. Introduction to principles of solar air conditioning

    Solar air conditioning system is mainly composed of solar collector two-part and absorption chillers.

    1.1 absorption refrigeration works

    Absorption refrigeration is the use of two substances composed of binary solution as working fluid. Both of these substances have different boiling points under the same pressure, high Nikon MH-21 Battery Charger  boiling point components known as absorbent, low-boiling components known as refrigerant. Common absorbent – refrigerant combinations there are two: one is a lithium bromide-water, is usually applied to larger central air conditioning; the other is a water-ammonia, is usually applied to small air conditioning.

    Absorption chillers mainly by the generator, condenser, evaporator and absorber components.

    This article a case of lithium-bromide absorption-type refrigerating machine. In refrigerator run process in the, dang bromide of lithium water solution in generator within was hot media water heating Hou, solution in the of water constantly vaporization; steam entered condensation device, is cooling water cool Hou condensation; as water of constantly vaporization, generator within of solution concentration constantly rise, entered absorption device; Dang condensation device within of water by throttle valve entered evaporator Shi, rapid expansion and vaporization, and in vaporization process in the large absorption evaporator within cold media water of heat, to reached cool refrigeration of purpose; this process in the, low temperature steam entered absorption device , Is absorbed in a concentrated solution of lithium bromide absorption, solution concentration and gradually reduce, by solution pumped back to the generator, to complete the cycle.

    1.2 solar absorption air-conditioning works

    The so-called solar absorption refrigeration, is the use of solar collectors required for the provision of the generator for absorption refrigerator heat medium water. Higher heat medium water temperature, refrigerator coefficient of performance (COP), the higher the higher the cooling efficiency of the air conditioning system are. For example, if the heat medium water temperature around 60 ° c, the chiller COP some 0?40; about heat medium water temperature 90 ¡æ, chiller COP some 0?70; about heat medium water temperature 120 ¡æ, chiller COP reaches more than 110.

    General absorption of air-conditioning system include absorption chiller, air conditioner box (or fan-coil), boilers, and other sections, and solar absorption air-conditioning systems are based more on solar collector and storage tank and automatic control system.

    In the summer, the heat heating hot water first enters storage tanks, when the water temperature reaches a certain value, from the tank to the refrigerator with heat medium water; outflow from  Panasonic Lumix DMC-TS1 Battery Charger vchiller and cooling water flow back to the tank, and set heat heating hot water; water to air conditioning refrigerant of refrigerator boxes, to achieve the goal of refrigeration and air conditioning. When solar energy is not sufficient to provide high heat medium water, supplemented by auxiliary boiler heat.

    In the winter, the same heat heating hot water into the tank, when the water temperature reaches a certain value, by providing hot water tank directly to the air conditioner box, for heating purposes. When solar energy is not able to meet the demands, and can also be supplemented by auxiliary boiler heat.

    In non-heating season, as long as the collector tank for heating hot water directly to the life of heat exchanger, you can gradually heating cold water in the tank to be used.

    2. integrated model system for air conditioning and heating

    Solar absorption air-conditioning technology to be put into practical application, in accordance with "95" national plan of scientific and technological tasks, solar energy Research Institute of Beijing built in September 1999 a set of China's largest integrated demonstration of solar absorption air-conditioning and heating system (see questions photos).

    Digital camera sliding shot perfect expression image

    Sliding shot with digital cameras is the most commonly used method of the camera, and was the most can express the image of the subject's methods. However, for some beginners tend to master well push-pull shot, shooting out wonderful lens.
    First, the characteristics of the track in

    Track in is the direction of the camera to be taken,
    Or change the Panasonic DMW-BMB9E,DMC-FZ40/FZ45/FZ100,DMW-BMB9 Battery Charger  lens focal length so that images from far and near to the framework be subject constantly close to the photo shoot. Motion pictures shot in this manner, known as push shots.

    Moving track in before you can form a visual effect, subject direction picture to be taken close to the screen performance view forward, forming a large landscape-level to smaller landscape-level continuous process of progressive, with the big King converted to small King of various features. Photograph face down on the peach blossom honey bees, you can use the method of track in from peach trees a panoramic view of the shooting, to push the lens where the bees peach branch, and then to peach, last close-up screen shot bees, so that the entire image is full. Figure.

    Push the lens can be divided into lots, push, fall three parts of the site. With the zoom in, being taken from small to large in the main screen at the same time, the main surrounding environment from big to small, or even disappear "painting".

    Second, the track in appropriate scenes

    1. push the lens constant that describes the environment in which the photo objects, and then zoom in, gradually out of environment space art, growing characters and becomes a screen, the main image. This is often used in the shooting sports award ceremony, such as shooting when extracted gold Nikon EN-EL12 Battery Charger  medal athlete, starts from player panorama and then gradually push the chest service gold medal, with flowers of panoramic lens has been pushed to the players hold the eyes with tears, vivid facial features of a smile, the effect is very significant.

    2. push the lens can also be used to highlight detail, highlighting the important plot elements. It can range from a larger picture and horizon space start, gradually moving forward close to the screen, and a detail image in the space, and by the driving this movement the audience's attention to the details. In some criminal cases detected in film and television, often see a police investigation at the scene, if you find any clues, usually track in pushing picture detail to highlight the importance of this discovery.

    3. push the lens also can use different propulsion speed to resize picture effects and rhythms, creating a strong visual impact, if advancing slowly and smoothly, to denote peace, quiet, calm and mysterious atmosphere. If promoting velocity drastic and short, often showing an atmosphere of tension and Fujifilm NP-45A Battery Charger unease, or excitement, anger and other emotions. In particular, hitch, photo taken dramatically larger, drastic changes from the steady state then the screen suddenly stopped, explosive force, keeps the screen very strong visual impact, have shocked and eye-catching effects, such as the recent coverage of the war in some commonly used this method to show the war bring destruction to the people.

    4. push the lens can be used to strengthen or weaken the movement of moving bodies. When we meet the camera lens figures track in that direction, picture frames and characters ' reverse movement, keeps the screen towards the oncoming people ran, bi-directional movement makes them meet in the Middle, its effects are clearly strengthens the character's movement, many seemed to have its motion accelerated. Otherwise, slow the movement of people away from. For example, in the film lovers break up, from the back track in picture effect will allow pace away lover dignified, as if there is a loss to Italy.

    Third, the method of track in operation

    Digital camera focal length changes considerably, using the track in a scene, can be implemented using some tools, such as tracks, vehicles, and so on, however, for General digital camera enthusiasts, and it is impossible to have those devices. You can use a digital camera zoom bar to shoot track in, namely camera focal length on the knob and, representing shooting the depth and scope.

    Shooting push lens Shi, you can first will focal length knob adjusting caused by Department, by Xia recording key records Hou, maintained several seconds still, this several seconds called "up site"; then adjustment knob, gradually from distance to near closer, then distance scenery in lens in the gradually increases, completed push lens in the push of process; arrived design good of shooting ended points Shi, then maintained still video JVC BN-VF815 Charger several seconds, completed "falls site" of shooting, such, a push lens on completed has.

    For programmes post editing convenience, when shooting in early track in pieces, down sites should have the appropriate length, generally remain in 5 seconds.

    Grade professional digital video camera Sony DSR-PD190P introduction

    Sony DSR-PD190P

    Home digital cameras since 1995 in Japan since its coming into existence to this day has passed 8 years. Here 8 years, science rapid development digital camera functions are all getting younger, smaller volume, weight price getting lower, general wage-earners also fun life can enjoy digital camera.
    Now civilian level digital camera is started with new law reinforcing popular in China, them generally in 500 lines horizontal resolution and Sony DSLR-A100 Battery Charger  SNR more than around 50dB, such digital cameras in less demanding business fora and programs produced are a cheap choice.

    However, in some special areas, such as education and health care, industrial production, the requirement will be clearly higher than the civilian level of image quality, but do not have to correspond to the broadcast level cameras, which highlighted the cheaper prices of such cameras, the volume is relatively small, and the image quality can be slightly lower than the special camera for broadcasting. This type of professional-grade cameras can be used in radio and television other than in the field of professional, such as Sony DVCAM series, Panasonic's DVCPRO and JVC professional series all belong to this level.

    This camera generally used 3CCD system, and compared to the single-CCD, because using 3 3CCD CCD convert red, green and blue signals, so take out images from color reduction than single-CCD to natural, good brightness and clarity than single-CCD. This advanced CCD imaging sensor technology can better solve some common photographic problems of, can provide wider range of recording and reduced video requirements for light even in a weaker light environments will also film blurred images. Adopts one-second-inch 3CCD Panasonic Lumix DMC-FS35 Battery Charger JVC companies GY-DV5001EC (440,000 pixel CCD); using one-third-inch 3CCD Canon XL-1 (320,000 pixels CCD); using one-fourth-inch 3CCD Panasonic AG-DVC15MC (320,000 pixels CCD), digital component recording parts of these digital camera system 5:1 compression, 8 bit digital quantization, track width 10 μ m, video bit rate of 25Mbps sth Their clarity, Snr, sensitivity, and other important indicators have been on and broadcasting of digital camera is not too much difference, just in terms of color reduction and automation still slightly down from the broadcast of digital cameras.

    Today described the best professional level digital camera is this level: Sony Professional levels of localization of DSR-PD190P.

    Suo Guang electronic company Sony in Shanghai China first established joint ventures since 2003, Suo Guang electronic coming on stream dozens of digital camcorder and digital cameras new DSR-PD190P are two weeks ago Suo Guang launched professional levels of localization of Sony digital camcorders.

    DSR-PD190P is a professional-level one-third-inch 3CCD DVCAM format digital video cameras, it is a highly upgraded version of the DSR-PD150P on the market (Beijing's bid to appear in a short few seconds of vision lenses is to use a DSR-PD150P shot of the red lanterns), inherited the DSR-DP150P all of the outstanding technical features, and a few higher audio quality and operability. DSR-PD190P and very broad range of applications--for example, news gathering, weddings, film, business and sporting activities and training content is produced, and so on, its superb performance and professional image quality so that it capable of a wide area of application.

    DSR-PD190P built-in three tablets one-third inches CCD, each tablets 450,000 pixel, are may for interlace scan and-by-line scan, can reached 530 line above level clarity; used has 12 times times optical zoom lens, even using high of zoom than, also can keep good of image quality; and other high-end professional digital camera as, DSR-PD190P used has optical anti-shake system--Sony patent of super smooth camera system, Level and vertical movement by all sensor independent detection, dang camera occurred jitter Shi, is located in lens behind of Prism system will adjustment and in Visual Shang compensation picture of swing, to reached guarantee fine image quality of purpose; audio lock mode can using audio and video keep synchronization, to implementation and professional of edit effect; handles of height than DSR-PD150P of improve has 10 mm, handles of design also for has improved, to more easy grasp, guarantee has camera Shi held holding camera of smooth sexual When used to purchase the NP-F960 lnfoLITHIUMTM battery, DSR-PD190P can be up to 8 hours of continuous recording actions; required flexibility in order to provide professional applications, DSR-PD190P a variety of manual adjustment function; memory photo camera function allows convert to progressive scan mode, still picture recording, memory mix function can be saved on the memory stick scene mixed with video images with the camera ; Use enhanced noise reduction technology, DSR-PD190P up to 1 Lux low light performance, making low light shooting pictures more perfect; DSR-PD190P the whole machine size 118x180x393 mm, 133x180x456 mm size after the installation of microphones, a stand-alone weighing 1600 grams. Now this machine sells for about $ 27,000 in the domestic market, because it is listed on the new machine, I believe there will be a certain room for price cuts, wants to buy friends can chibiguanwang for the time being.

    Advantages:

    1, DSR-PD190P in the DVCAM format, 8-bit digital component recording, compression ratio is 5:1, the sampling ratio of 4:2:0. This unique compression mode, to provide exceptional image quality and multiple generations of Super copy;

    2, when using DVCAM video tape with IC memory, you can index tag, which is one of the special features of the Sony original. This feature allows operators to videotape location for quick access to mark index, more convenient and practical;

    3, DSR-PD190P equipped with the new development of 210,000 pixels high resolution integrated LCD, transmissive and reflective LCD screen features in combination. Making LCD screens at any lighting conditions can clear display;

    4, DSR-PD190P LCD screen and the Picture Finder can be used together, like we usually use digital video camera, can only be used a JVC GR-DVL365 Battery Charger framing device, this innovation allows the operator to use Picture Finder while focal length adjustment on your subject, you can use the LCD to adjust color balance;

    5, DSR-PD190P compact, only 118x180x393 mm, weight is only about 1.6kg. Although shoulder-, long shot will not make users feel tired;

    6, and the supply of Sony accessories of past models seem a bit mean difference is--DSR-PD190P random VCL-HG0758 wide angle lens provides high performance, and supporting the convex mirror lens hood LSF-S58, provides users with a more broad space shot.

    Disadvantages:

    1, 0.44-inch monochrome LCD Picture Finder, horizontal resolution 500 TV lines; for friends are accustomed to color viewfinder bit too smoothly, while many professional models are monochrome viewfinder, but considerable part of users also prefer a color viewfinder, because viewfinder accuracy with it higher than monochrome viewfinder;

    2, while the supplied accessories such as the wide angle lens, but more parts or additional cost, the spare parts price of Panasonic Lumix DMC-FS35 Battery Charger  Sony that is shocking, people could afford horses not good saddle feel;

    3, when progressive scan mode is used, can only record a still image, cannot be used to record moving images, make people feel a bit sorry.

    Shoot dynamic-condensed articles

    We taught on a fuzzy approach to the performance of the main dynamics of this issue DCFever.com then teach you another manifestation of the dynamic photography - condensation. As the name suggests, this technique is to Panasonic DMW-BLB13 Battery  condense the main action of the moment to freeze up like a specimen like, because photographs can be very clear record of invisible condensation dynamic images, pictures are to have considerable power to shock.

    Equipment preparation

    To speed the movement of the body and turned into sharp focus photographs, we need to focus and shoot a high response camera. Ideally, of course, the focus quickly, a short delay, single-lens reflex machine, even a few thousand dollars of Canon EOS 300D, you can easily capture such images. If you use DC, then, can also pre-focus approach to solve the speed problem focus, which we can talk about later.

    On the other hand, because of this shooting skills needed to use with high-speed shutter, so the camera lens aperture can be Fujifilm FinePix J30 Battery Charger   larger if it is more favorable. In addition, many are not too close when we take these pictures, a long focal length lens is necessary. The choice of lens, Canon EF 28-300mm f/3.5-5.6 L IS USM, EF 70-200mm f/2.8 L USM lens, etc. are good choices long. If the DC shooting, then, Canon PowerShot S1 IS also a popular choice lately.


    Shooting a moving subject, with D-SLR will be more convenient.

    Canon's new EF 28-300mm f/3.5-5.6 L IS USM is a good dynamic photographic partner.
    Points taken

    Basically, the shutter speed   condensation techniques need to use a higher shutter speed, but how fast will depend on the subject to the action may be. If you take pets, children, pedestrians, then 1 / 250 seconds shutter is sufficient. If you want to shoot football, basketball tournament, it is best to have 1 / 500 second shutter speed. If you want to shoot real vehicle, and baseball, then because of very high speed, may need to use 1 / 1000 second shutter is not surprising. Can be used when shooting shutter priority automatic exposure mode, shoot a few photos first carefully review the photo resolution, if the subject a little fuzzy, then it should consider increasing the shutter speed, ISO, and increase the aperture of.


    The shutter is too slow, the main become blurred.

    Increase the shutter speed can result in clearer pictures and body.
    The larger the aperture   aperture, shutter speed can be faster, help improve the success rate of the photo. However, if sufficient light shooting, but the main action not too fast, you can try to reduce an aperture to increase depth of  JVC GR-SXM265 Battery Charger field, and smaller and an aperture also help to improve overall picture clarity.

    A sense of brightness when the brightness depending on the shooting ︰ and the main action, if you have to adjust to the maximum aperture the shutter, but still not fast enough, then it attempts to increase a sense of ISO brightness. Adjusting the magnitude of the best is just good, high ISO to avoid attracting too much noise. If ISO 200 has sufficient condensation move, adjusting to the ISO 400 is just noise to improve it.

    Focus   If we use D-SLR, then adjust the focus mode to continuous movement can make the main subject sharp. If the DC shooting in general, focus speed could not keep up with rapid body, we can anticipate the movement of the main line, pre-focus point in the course of which, such as the main arrival they press the shutter.


    Canon EOS 300D has a seven-point autofocus, plus sports photography mode, designed to track moving subjects.
    Even if the subject is fast-moving, AI Servo can easily capture the main dynamic.
    Choose the main ︰ condensation photography can only hint the subject is in motion, because the photo is not actually the main action, so some of the main shoot is not suitable for this technique. For example, to shoot a high-speed speeding racing, racing at high speed shutter is the same with the rest. But if we can add some photos, "the moment" element, such as exhaust pipes emit sparks when the car into the corners two wheels off the ground, the effect is entirely different.

    The same rate of speed change subject, with the relative position of different photographers, different relative speed. For Nikon Coolpix S630 Battery Charger   example, the relative speed of oncoming vehicles is the lowest, with a slower shutter can also be condensed, but when the car crossed in front of the photographer when the relative velocity becomes the highest shutter speed will be increased accordingly. On the other hand, if the film continued to repeat the exercise the subject, can usually find some place is particularly slow speed. For example, take a swing girl swing when the swing to the highest speed is the lowest when the photographer pressed the shutter should be at this time. If you take the car if the car speed into the corners and certainly lower than the straight

    Condensation of a car at high speed shutter dynamic, results with shooting a stationary car is no different.
    Swing swing to the highest moment, is the lowest moment of the main speed.

    Composition introduction of express travel photography

    Friends often ask us why to travel at a time, seeing a lot of beautiful scenery, but after the camera seems ordinary odd. Obviously incredibly wonderful scenery, in the photo seems incredibly boring. "Is there anyone so that easy skill transfer? "Methods of course! Go shooting at once!

    Use of perspective techniques

    The so-called "perspective", is actually drawing skills relating to express stereo a skill on the plane, one principle is that distant objects appear smaller, nearer objects appear larger. When we use a wide angle lens when shooting that it would be more easily captured photo with a sense of perspective, for example in the photo, for Panasonic DMC-TZ5 Battery Charger  example, photos with 24mm lens shooting, watching the roads leading to the monument in the distance, near photographer will render the more spacious feel, the more close to the monument is more narrow, until far into a vanishing point on the screen. Change of appreciation from the path width, will be more easily focus on boot to the monument. On the wide angle landscape shot, this is a very common technique.

    Use of perspective techniques, using convex mirror heads the building near large far-smaller properties, you can easily boot to appreciation of the focus is on the theme of vanishing points in perspective.
    Using the lens characteristics

    Flexible use of different lens effect properties, you can make the photo look more play. Convex mirror heads (such as 24~28mm focal length) or ultra wide-angle mirrors (such as 17mm focal length) film, photos usually look more momentum, so when shooting landscapes, usually using wide angle to shoot, even if the photo look as if the scope of Nikon Coolpix S8100 Battery Charger  part distortion, but this distortion is to make the photo more charming secrets! The other hand, telephoto lens, or shallow depth of field effect characteristic of large aperture lens, can express after Qing Mongolia dreamy effect. When as topics when photographing local features, you can schedule a hope that the prominent theme in clear depth of field position, compared to whole Zhang Jing deep scope clear photo, no doubt, more artistic taste.

    Wide angle lens, or fisheye lens due to take a broad perspective, incorporating more content in the photo, feel it is very easy to enjoy magnificent great momentum.
    Composition of slash

    Composition of slash composition is also an activation techniques. Diagonal composition of features is to make the photo look not so dull, at least it feels that you have wanted to deliberately create an effect, rather like a beginner, please finish it as shadow of hope its well organized a to this-a photo tour called. Composition of slash another benefit is that as far as possible with

    Improving travel photo tips
    1. pay attention to exposure compensation: travel photograph emphasizes flexibility or convenience, people or using Auto or semi manual (P/A/S) mode, however at this time or slightly backlight but do not know--seems to be nothing on the LCD of the camera, but back to the computer only to find the back light is a constant thing. When shooting landscapes found Panasonic Lumix DMC-FZ50 Battery Charger  when the sky was white rather than blue, light pictures of the sky at this time range, suitably increase the exposure compensation as 0.7EV NM, can help avoid problems with photo underexposed.

    No adjusting exposure compensation

    Adjusting exposure compensation

    2. avoid the crowds: a sometimes live in tourist areas, surrounded by passers-by a, b, c, thought should be impossible to take a good photo. Sometimes change angle of composition, such as when shooting a wide range of attractions, may wish to leave the shooting angle slightly on the back, or may be unnecessary at this time of people excluded from the lens, thus allowing the composition becomes more pure.

    Composition of population covered with

    Avoid the crowds

    3. break the existing law: every man has his personal shooting preference, this shooting habits from the cumulative, each composition biased tendency to use several shooting modes, himself unable to break through, after which you will find long good composition is stuffy. Solution so simple in fact, just using their preference after the  JVC GY-HD100U Battery Charger shooting at a time, move the lens angle of shot, and then see if they have no method of thought. In these two photos, side framing and composition of symmetry has no called correctly, everything, as long as they try to, will definitely surprise.

    Light source orientation awareness of light white and various parallel backlighting
    • hotography is the art of illumination, a light source on the subject, the term has been decisive in the direction of impact. In General, the most common light source can be divided into three main: feri, backlight and  Nikon Coolpix S610 Battery Charger half light. Different light direction, not only in order to differentiate between the severity of the filming, shall also apply.
    • CIS light
    • If the camera and light source irradiation direction direction in the face of it parallel to the light. The exposure of light because of the CIS, mainly in relation to the object is directly affected by light, it is not obvious effect of the lighting effect evenly, the shadow effect is the price looks more flat, but the benefit need not be more saturated color.
    • In fact, when shooting flash fill Flash, can be considered a parallel to the optical effect. DSLR beginners of light most available effects, plus light also believe that in the first place, that is to say, because many DSLR metering Metering mode is set by default to the number of the region, making it easier to JVC GR-DV400 Battery Charger  mix the Shun shooting you want exposure to the effects on the environment, and brightness uniformity.
    • Features: the main source of light, color saturation, but considers that more plans in effect. Newbie is relatively easy to master. Degree of difficulty 
      Light side
    • If the camera and light source, for example,-90 degrees (angle can be changed, of course), it is part of. Contrast to shun the light effect, where the principal to light, often only the amount of light, the rest is part of the shadow. In other words, the contrast of light is evident in the photographs of shun.
    • It is therefore appropriate to make use of light, maybe big game creation. For example, if you want to take the main surface textures, and texture and the like, it would be a great choice, but relatively speaking, if you would like to express the feeling of a good part may not be best to consider the delicate portrait. When shooting buildings, for its part, is to drag a long shadow, makes buildings full majestic feeling.
    • Main features: stereoscopic effect more contrast, easy speech, shadow scope or require extra lighting. The Severity Of The
      The Backlight
    • The backlight is not contrary to the situation in front of the camera light shun happens to be the direction of Panasonic Lumix DMC-ZS3 Battery Charger  the light source. Autumn leaves, to make arrangements, intelligent backlight using thin film technologies the opportunity to highlight sheets sheets and transparent texture sort order. If you set the backlight portrait, hair, face, portraits made photo and more to create light and shadow effects, such as the presentation of the shoulder with a portrait session, helps profile and thin clothes of the light effect is displayed it, it feels pretty good.
    • However, it requires skill, especially in the backlighting of the shoot, warning flares lighting, Lens, and the problem appears to be a problem if you have fluorescent, it is necessary to increase exposure compensation using a central spot metering/spot metering mode or using flash in a Flash, in order to avoid problems with underexposed object.
    • Characteristics: easy to highlight the main mürakontuuride and textures, to pay particular attention to the background of the light and flares. The Severity Of The
    • Natural or artificial light sources
    • When drawing up the real, natural light and artificial light sources, the shooting is different. For example, when shooting landscapes, natural light is the Sun, of course, but the position of the Sun and Kodak Zi8 Battery Charger  nature scenes, cannot change their photographer adjusts. Artificial light sources are different, for example, Live Studio Photography, the photographer receives a Flash of light, easily adapted to reflect the change and impact.

In sum, while Pavilion dv4 in overall design and without too many highlights to speak of, but you can in many details, feel the charm of this product.

    Well, on looking forward we come to an end, please follow the author below, to learn more about this product appearance design of the overall situation, see if you like this design?

    Product: dv4-3011TX HP notebooks look article: designing stable introverted losing fashion
    · Appreciation of the overall design

    HP Pavilion series laptop at home for its market, have always had a good reputation, neither the design nor the hardware configuration, are the best in its class. The launch platform for new products, don't shame the consistent tradition of the series, though on the housing material is only using the ripple in the ordinary piano paint and film printing, but from which you can see the characteristics of solid workmanship series, also remains on HP Home notebook industry chain of "ambassadors".



    HP dv4-3011TX die as piano paint gloss-material to create

    HP dv4-3011TX to the overall look of the new black tone, Silver metallic around the waist line around the body, silver with black match is also portable is a classic color matching, with introverted black to achieve the goal of stable fashion, to sense prominent silver metal moulding machine even more lively, more textured. While the surface of the body, of quadrilateral membrane ripple in printing technology to create a decorative Obscurus nose touch overall, is not apparent at the same time with a line so that it does not affect the overall sense of calm.


    Overall to black tones, complemented by Silver metallic waist line decoration

    Pavilion dv4 is a 14-inch mainstream laptop, taking into account both the portability, and to ensure to provide users with clear enough, a broad vision. Display resolution 1366x768 pixels of the current mainstream, 16:9 zoom and more for home use of portable visual experience for the user. LED backlit material make it more energy-saving to help laptops effectively extend battery life, at the same time provide users with clear, sharp, realistic Visual effects.


    14-inch mainstream size screen

    Every HP Pavilion series notebook products, will be printed on the top left corner of the body of metallic "HP" LOGO, this time the Pavilion dv4-3011TX is no exception, that for most embedded in the top cover for big logo in the Centre, HP logo and the overall design styles complement each other, quiet, and calm, without losing the sense of fashion.


    The fuselage top cover part of the "HP" LOGO

    Today, the vast majority of portable body design of the product is very flat, this relationship with thermal components within the arrangement is, Pavilion dv4-slope design of body, of course, and distribution of thermal components are not linked.


    Rear of the fuselage higher than the front end to a lot of

    For notebook user,, we and notebook contact up to of undoubtedly is around wrist supporting, and touch Board and keyboard, therefore because most notebook computer of thermal components are distribution in keyboard part, so we in using process in the Association was hand Department is hot, and dv4 to makes user feel more cool, therefore will thermal components design in has fuselage by Hou of location, so we see entire fuselage of Hou Department to than front-end high out many, and and another aspects, this Qian rushed type of design makes overall looks more has dynamic.

    · Allocated interface and layout overview

    Household as a high-performance gaming notebook computers, in addition to outstanding performance on the performance, you also need support for more users on the overall entertainment value, so on top of the fuselage, Pavilion dv4 user equipped with a more spacious area of auto voice from Blue Star unit, and has adopted Dolby Home Theatre audio certification, sound output effect is very good. However, there is no carry HP latest Beats Audio sound system, still it is a little regret.


    Equipped with auto Blue Star speakers


    Left side of the fuselage interface distribution

    In the interface configuration, Pavilion dv4 integrates all the most commonly used in the main interface, and its layout is relatively also needs to be improved. In the left side of the fuselage, the model provides users with a DVD burning optical drive, 1 USB 2 interface and 1 set the audio jacks; and in the right side of the body, it gives users the power jack, VGA port, RJ-45 Ethernet ports, 1 HDMI HD interfaces, one card reader slot, 1 USB 2 interface and one security lock hole.


    Right side of the fuselage interface distribution

    From an overall interface arrangement, Pavilion dv4 security lock hole location is different, closer to the front of the fuselage setting mode is extremely rare, of course, this little impact for the average user. Design of Ethernet interface in the right side of the fuselage idea less than ideal, this feedback has always been can be seen from the user, and HDMI, VGA, power lines are set on the right, for right handed users who use the mouse, will cause some inconvenience, this is debatable.

    · Keyboard design overview

    Advantages and disadvantages of  DC Power Jack for HP Pavillion ZE5600 a notebook, we not only its appearance, without attention to detail, because even design and gorgeous, fashion, if Polish do not place enough of the details, then, would be called qualified products. A solid Dyke can collapse because of an Ant hole in it., details of the often seemingly inadvertent negligence, will in the cumulative use of visually important impact on the life of the machine. Below, please look at HP Pavilion dv4 with the author of this product, in terms of both design details what are the areas of concern.



    Overall design of the keyboard part

    To stand out in a large HP Home notebook computer, and is widely recognized and favored by the users from dv4 screen axis damping control will be able to see one or two, although not as perfect as the ThinkPad t series control, but is enough to make you can lift the top cover with one hand only, reflected a considerable feat. Top cover after setting off, we can see the dv4 throughout the c part of the design, color on the calm, quiet, materials and technology on the fashion with seemingly contradictory yet integration is in place, both to satisfy the aesthetic needs of home users, and to apply business office crowd, can be called two birds with one stone.


    Metallic screen axis and function keys

    Now of notebook design has does not like years Qian as some paranoid of to pursuit easy sexual, such as to various function button integration to conspicuous of c surface Board Shang this class of practices, in today seems has is too traditional has, therefore we intentionally or unintentionally Zhijian found, today of notebook products you is difficult to in fuselage Shang then found that a row row of function press, instead of is simple, and is highlight necessity of design concept.


    Chocolate-the key cap design

    It can be said that Pavilion dv4 is a typical representative of this product, on the fuselage in addition to the necessary power supply and a quick open browser outside of the function keys, you cannot find any extra buttons. But don't worry, did you see the keyboard's top row F1-F12 key? Yes, press them directly, you can achieve the keycap identifies the corresponding function on, while traditional F1-F12 key needs through Fn key to implement appropriate functionality. Common keyboard uses HP dv4 laptop chocolate key caps, square Cap surface distribution to scrub colloidal coating to enhance feel comfortable.


    Design of touchpad

    For this in the high-end products,, little of touch board design natural goes without saying, positioning accuracy, and control comfortable of, and press key Cheng rationalization course to do as possible of no can critical, Pavilion dv4 of touch Board in design Shi clearly for this several aspects Xia has many Kung Fu, fog surface material auxiliary to small of mill sand particles enhanced has using feel, left Shang angle of rectangle box for touch Board lock regional, gently percussion two Xia, to lock touch Board, lock zhihou, touch Board median top Department of LED light issued red backlight be prompted.

    · Body analysis of other design details


    Front rear and thickness of the thinnest Department comparison

    We said in the previous sections, dv4 rushed before the machine body adopts the style of design, to a large extent is related to arrangement of internal thermal components location, we use a dollar coin thickness on the fuselage front and rear were compared, from the two pictures above, believe you can also clear experience Pavilion dv4 basic situation of body thickness.


    Corner part of the transition

    Fuselage was corner arc is often not noticed, but it directly affects the whole gives the impression of the machine. For business notebook,, most important of is to to people to steady of DC Power Jack for HP Pavillion ZE5613EA feeling, therefore we will found, many business this in fuselage line especially corner line of design Shang, are is "cross flat vertical, corners distinct"; and for household notebook computer,, can select of design mode on many has, small radians of intelligent, also or large radians of round, under overall style of different selection most appropriate of radians control to let people feeling comfortable.


    Rear fuselage with a certain degree of arc

    Pavilion dv4 on the application of body lines, on the use of a wide arc of round design. Because of its overall color scheme and design details are highlighted on the calm and quiet, if corner lines do follow, were deprived of home style unique to laptops. Therefore, large rounded lines of the arc is filled with a fuselage around, make it overall looks more mellow, full, more flavor home laptop.

    Business experience: for general users
    · Business application experience

    Business this might not necessarily when the home was used, but the household entirely capable of when the business would have been used. Pavilion dv4 is no exception, of course, 750GB large hard drive capacity for user data provides ample storage space, and stability, and to ensure the security of user data, and 3 hours and 21 minutes of battery life, while not as dynamic as the business notebook lasting, but also to guarantee without electricity during office hours.



    Business application experience

    In addition, the product in the Windows 7 preinstalled appeared family Standard Edition operating system, genuine trusted operating system stability. On the software side, the models preinstalled Office 2010 Starter Pack for users, Norton antivirus software, and PowerDVD 10, in addition to several utilities to provide users with convenient for business applications.

    In terms of mobility, 14 die zhongguizhongju, 340x238x28.1mm of body size in a 14-inch mainstream notebook size level, 2.245kg and 2.743kg travel with battery weight weight can also be satisfactory. At the same time benefit from the overall excellent hard

    Professional tool essential to have

    SDC is SAMSUNG the digital camera special kind of video frequency format, therefore objectively say, currently Internet up can be provided as the SDC format video frequency resources of download isn't a lot of.Morely still keep needing and carrying on the video frequency of other formats through a software a conversion to customer.The SAMSUNG then provided such a software-Digimax Converter in the random CD.It is the tool that exclusively uses to carry on a SDC video frequency format conversion.The gearing of 
    Nikon EN-EL14 Battery Charger Digimax Converter is pretty much simple, the physical volume of software is also not big, hint to operate to complete according to the menu.

    How to use Digimax Converter to convert film:

    The 1st step adds the film to criticize a list in

    The list shot "add" buttons or uses menu order"document → add", will the film changing add a conversion list.The software supports the conversion that carries on several video frequency documents once, but customer need to add all of them to the conversion list then.You can change a film conversion order of sequence, or pick out at the same time parts of video frequency documents to carry on a conversion among them.Moreover, if video frequency document that need to be converted is more, suggest that you builds up manies to convert a list, because Digimax Converter support to the conservancy that converts a list and re- load in, can have the management of preface your video frequency document more so.

    Tips:

    If you delete a source document after thinking at the completion the conversion, needs to choose that"conversion after delete" options is then.Moreover if the computer didn't install a machine the essential plait decoding, then will show "the type didn't register" news in the status column.Need to install the correct plait decoding machine first at this time, then convert a document.

    The film format of conversion that Digimax Converter software supports contains AVI, WMV and ASF or MPG(MPEG1).Is also say, usually as long as is the video frequency film that can be in the Player software carry on broadcasting at Windows Media all can use Digimax Converter to carry on a conversion.But the video frequency format such as RMVB then need other video frequencies of before the event uses to convert software, it converts into  Panasonic DMC-TZ5 Battery Charger Windows Media the Player can broadcast of format after, just can on Digimax Converter the format conversion of carrying out SDC.

    The 2nd step adds sub-title

    The 3rd step shears to slice and previews a video frequency

    At Digimax Converter right department the window way that designed a video frequency player, so can the convenient customer watch or edit a video frequency source document.The exportation video frequency that can preview to take sub-title before converting also carry on shearing Ji, the way of doing is to use the player in the software the red arrowhead in the spooler come to be establishing the beginning position and be over position of converting the film under.At the same time, you can still just player just under see to output anticipating of film keep on time and document all of the informations, design since in brief again overall.

    The 4th step carries on a conversion constitution

    Digimax Converter provided more abundant video frequency to convert a constitution.Because in numerous SAMSUNG digital camera, current 4:3 traditional LCD specifications, also have 16:9 breadths hold a proportion, therefore the software provided these two kinds of different video frequencies to output specification with satisfy different model of show a demand.In"size" options, Digimax Converter provided 420 ×s that 480 pixels and 320 ×ses 240 pixels and suitable breadth held from 640 ×s 240 the pixels are three kinds of exportation sizes, the rate can choose 30 fpses or 15 fpses, you can according to the memory card capacity and oneself for broadcast the demand of effect to choose.On top of that, the software provided to use to "shear to slice an options" of adjusting the appearance size and can carry on limiting"partition size" function to the film document size.(Figure 6 conversion constitutions)

    You can choose with the SAMSUNG camera memory card capacity to should of the capacity all of the optionses:32 MBs, 64 MBs, 128 MBs and 256 MBs or 512 MBs, so can't appear can not broadcast in the camera because the film leads greatly of circumstance.Certainly if memory card capacity were enough big, you would also choose infinite make exportation.

    The 5th step converts

    Top one step after converting a constitution the completion can start carrying on a document to convert.Your important business chooses first to output a document to clip and outputs a document(recognize tacitly circumstance under, procedure will conversion behind of document and source film the conservancy clip in the same document in, output document famous general to take[SDC] front Zhui with.SDC document file extension), then the list shot converts and starts converting and criticizes all films that take and have choice marking in the list.Film conversion of at the same time, you can still be seeing enter synchronously and quickly in the browser window way of video frequency image, generally come to speak, a video frequency part of conversion time is the video frequency broadcasts of 4 times soon or so, is also say a video frequency film that grows for about 40 minutes, it converts process to probably take 10 minutes around time.At the same time in the process of converting in, also have already used to convert time and surplus to convert horary progress to suggest on the software, make people see at a glance.

    Film at SAMSUNG digital camera up broadcast

    The video frequency that creates a good SDC format, you can make duplicate it to the memory card, and come up to broadcast in the camera.The SAMSUNG digital camera has strict restriction to the position that the SDC document deposits, have to start to build up a document that is named "PMP" first to clip under the memory card root catalogue, and  JVC GR-D347U Battery Charger  save the SDC format film to the document to clip bottom, the camera is after starting PMP function, would look for and display the document.If saving path not to, camera will hint to can not find out a document, this needs a special attention.

    Compared with the number of industry site visitors to MSN industry greatly decreased, number has the certain ascend, in December 2010 7940 million, compared to January increased 6.95%, but it still lags behind netizens overall growth. Use construction.some specific system built to MSN possession visitors number only accounted for all visitors to MSN, in the first half of the amount of 38.84% between procedures used to build the visitor quantity reduced to MSN 22.19%, show that using construction.some specific system built to MSN loss visitors (Nikon Coolpix S560 Battery Charger) number is caused to MSN overall trade visitors decreased the main reason. The number of visitors to MSN is active, unsatisfactory December active 2478 million visitors, a number of January reduce 0.3%.

    Due to MSN kind website homogeneityphenomenon serious and the strong stronger as the essential attribute, caused the visitor to the small and medium-sized websites of abandoned, this makes the industry visitors quantity dropped substantially. With Facebook is different, domestic to MSN kind website provides services simplification, makes many visitors are tired, it caused a large number of visitors loss.

    The personage inside course of study points out, to MSN kind website centralization is the inexorable trend of small and medium-sized websites have a difficult super big rival, estimated in the future will also have a large number of small and medium-sized to MSN disappear, industry site number will continue to fall. The current domestic to MSN facing the most serious is a core problem haven't find a better development direction, simply by social game to (Panasonic Lumix DMC-FX550 Battery Charger) attract and expect to keep visitors, as visitors to appear tired, website couldn't provide updated more interesting function, how to demonstrate to MSN's unique charm, how to establish China's Facebook faced with China to MSN operator has become urgent problem before

    Digital cameras use lithium batteries misunderstandings

    Use one of the mistakes of lithium batteries: batteries for as long as the least, so that you can to a certain extent, to extend battery life. This is wrong, because it ignores the lithium battery aging nature. Lithium-ion battery power after since the factory began to decay constant, even if it is not recycled, its part of the power loss is permanent, a phenomenon that we call the aging effects of the &quot;battery.&quot; It and Ni-MH battery &quot;memory effect&quot; that will lead to the reduction of battery power.

     Lithium-ion battery with little memory of powerboy NI-CD batteries. Excessive charging and excessive discharge, the lithium-ion battery positive and negative result in permanent damage resulting out of the following two errors: error 2: lithium batteries have run out of power before charging. This is wrong, it is best to only 20% of the electricity-40% of the time. Lithium-ion batteries are usually equipped with control circuit for charging or discharging. For lithium batteries, preferably a partial discharges, rather than a full discharge. The actual testing indicates that if the battery is placed into each cell 2.5 v below, although the battery internal safety circuit will start, but this time the battery becomes somewhat easy to use. The results can only be made before the battery scrap

    Myth three: the first three single charge should be full of 12-14 hours. This is a transitional charging performance. First of all, it was felt that the depth of filling, can inspire battery activity, promotion of lithium ion batteries. According to experts, this just doesn't understand the mechanism of lithium batteries of interesting imagination, depth of charging or discharging will only cause additional lithium-ion battery positive and negative of permanent damage to the

    Third erroneous zone: The first three charges should fill for 12-14 hours. This is the transition charge performance. First some people believed that the depth sufficient, puts can be possible to stimulate the battery activeness, the promotion lithium ion battery's actual capacity. According to expert's reply, this did not only understand lithium battery's mechanism forms the interesting imagination, the depth sufficient, the electric discharge can only extra create the lithium ion battery plus and minus permanent damage.

    New battery display sometimes incorrect, such as the battery is fully charged, it still shows 96%. Several charging or discharging cycles, gradually reached 99%-100%. In fact, this is battery detection circuit no sampling to enough data, before correction values in registers. Battery from the battery of the chemical properties of the decision, the displayed value is only a reference. The so-called new batteries before using three full-charge, on the &quot;activate&quot; in the eyes of the experts, but also many rumours.

    In the light of the above, as long as the normal charging lithium battery is OK. Moreover, now the lithium battery charger are equipped with LEDs, charging is completed by a red led will turn green If your battery has been activated, it is not necessary to fully discharge and then charge. Many lithium batteries when activated--given that many consumers on lithium batteries do not understand that treat of NiMH batteries to treat the lithium-ion battery, which makes the life of the lithium-ion batteries, so many battery when activated. Lithium battery activation by 3-5 times the normal charge and discharge cycles
