| 20090065188 | Water quality control method for an evaporative cooling water chiller and a system thereof - A water quality control method for an evaporative cooling water chiller uses a water pump to transport cooling water from a water tank to a water-spraying element via a water pipe. The cooling water is sprayed onto fins and a refrigerant pipe of a first heat exchanger, flows along the fins and is collected in the water tank. Thereby, the cooling water reduces the temperature of the heat exchanger. The water pump is set to operate for a first period and to stop for a second period so that the temperature of the fins and the refrigerant pipe increases. Thereby, the limescales attached to the heat exchanger are detached and drop into the water tank. Subsequently the water pump is turned on again. The cooling water in the water tank flushes out the accumulated particles on the bottom of the water tank, and clean cooling water is added. | 03-12-2009 |

| 20090234990 | KVM SWITCH SYSTEM SUPPORTING DVI VIDEO FORMAT - A KVM (keyboard, video, mouse) switch system includes a console module and multiple computer modules connected to the console module in series. Each computer module is connected to its upstream module by two Category 5 cables. Video signals are transmitted between the modules as digital video signals in the DVI format. A computer is connected to each computer module, and a user console is connected to the console module for selectively control one of the computers. The console module controls the computer modules so that one of them is in a connect mode and transmits video and keyboard/mouse signals between its attached computer and its upstream module, and all other computer modules are in a connect mode and pass video and keyboard/mouse signals between their upstream and downstream modules. By this configuration, digital video signals can be transmitted from computers at a large distance away from the user console. | 09-17-2009 |
| 20100095031 | Dongle Module, Console Module, Matrix KVM Switch System, Local-End Module, Remote-End Module, and Extender System - A dongle module including a digital video differential signal input terminal, a keyboard control signal I/O terminal, a mouse control signal I/O terminal, a processing unit, a transforming unit, a synthesizer unit and a signal I/O terminal is provided. The digital video differential input terminal receives a digital video differential signal, which includes multiple differential data signals, a differential clock signal and multiple low-frequency signals. The processing unit processes the low-frequency signal, a keyboard control signal and a mouse control signal to obtain a digital hybrid data. The transforming unit transforms the digital hybrid data into a differential hybrid signal. The synthesizer unit receives and composes the differential clock signal and the differential hybrid signal into a differential synthesized signal. The signal I/O terminal receives and outputs the differential data signals and the differential synthesized signal. | 04-15-2010 |
| 20100124270 | CABLE LENGTH DETECTION AND SIGNAL COMPENSATION APPARATUS AND METHOD FOR A KEYBOARD VIDEO MOUSE SWITCH AND EXTENDER - An apparatus in a video signal transmission system for measuring cable length and compensating for cable loss is described. A number of pilot signals of different frequencies are compressed into one of the three color signals during the vertical sync periods in a time-division manner. The vertical and horizontal sync signals are compressed into the other two color signals. The video signal is transmitted over a cable having at least three pairs of wires, each color signal being transmitted by one pair of wires. A pilot signal converting circuit obtains the levels of the pilot signals transmitted by the cable. A compensation control circuit averages the levels of the multiple pilot signals of different frequencies over a number of vertical sync periods, and generates compensation control signals based on the average level of the pilot signals. The compensation control signals are used to perform video signal compensation. | 05-20-2010 |

| 20080218633 | Method and System for Transmitting Video Signals - The first device receives the video signal to encode a horizontal sync signal and a vertical sync signal of the video signal into a composite sync signal, compresses the composite sync signal into one of three color signals of the video signal, and transmits the three color signals. The second device is in communication with the first device, decompresses the composite sync signal from the compressed color signal, and decodes the horizontal sync signal and the vertical sync signal from the composite sync signal. A method for transmitting video signals and a KVM device are also disclosed. | 09-11-2008 |
| 20090079868 | Method and Apparatus for Transmitting a Video Signal - An apparatus for transmitting a video signal includes a signal detector, a multiplexer and a transmitter. The signal detector detects the video signal from the source to determine whether the horizontal sync signal and the vertical sync signal of the video signal are independent or composite. The multiplexer generates a composite sync signal by combining the horizontal sync signal and the vertical sync signal with reference to timing characteristics of the horizontal sync signal and the vertical sync signal while the horizontal sync signal and the vertical sync signal are detected as independent signals, and bypasses the composite sync signal while the horizontal sync signal and the vertical sync signal are detected as the composite sync signal. The transmitter transmits the video signal with the composite sync signal to the destination via a media. A method for transmitting the video signal is also disclosed. | 03-26-2009 |

| 20090080538 | Method and Apparatus for Decoding a Video Signal - An apparatus for transmitting a video signal has a receiver, a processor and a multiplexer. The receiver receives the video signal and separates a composite sync signal from the video signal. The processor generates a vertical sync signal and a selecting signal with reference to timing characteristics of the composite sync signal. The multiplexer generates a horizontal sync signal by selectively outputting the composite sync signal when the selecting signal is at a first logic level and outputting a reference signal when the selecting signal is at a second logic level. A method for transmitting a video signal is also disclosed. | 03-26-2009 |
