| 20120029860 | TEST CIRCUIT FOR NETWORK INTERFACE - A first output pin of a microcontroller is connected to a control pin of a high speed switch chip. A second output pin of the microcontroller is connected to two control pins of first and second switch chips. Two output pins of the high speed switch chip are connected to two input pins of the first switch chip. Two input pins of a third switch chip are connected to two output pins of the second switch chip. Two control pins of the third switch chip are connected to a third output pin of the microcontroller. Three input pins of a bus switch chip are connected to fourth to sixth output pins of the microcontroller. A load board is connected to six output pins of the bus switch chip and four switch pins of the first and second switch chips. | 02-02-2012 |
| 20100311389 | WIRELESS COMMUNICATION SERVICE SYSTEM AND TRANSMISSION METHOD THEREOF, AND MOBILE PHONE AND DIALING METHOD UTILIZING THE SYSTEM - A wireless communication service system and a mobile phone are provided. The mobile phone generates a calling signal of a recipient number and determines whether a storage unit has stored a cornet associated with the recipient number. If the storage unit has stored the cornet, the mobile phone sends a transmission containing the cornet. If the storage unit has not stored the cornet, the mobile phone sends a transmission containing the recipient number. When the wireless communication service system receives the transmission containing the recipient number, the wireless communication service system determines whether the recipient number has joined a cornet cluster network of a caller number. If so, the wireless communication service system calls the cornet. If not, the wireless communication service system calls the recipient number. | 12-09-2010 |
| 20080281446 | AUDIO SIGNAL TRANSMISSION CIRCUIT - An exemplary audio signal transmission circuit includes a codec to provide analog and digital audio signals; an amplifier connected to the codec to receive the analog audio signals; a control circuit connected to the codec to receive the digital audio signals and connected to the amplifier to selectively turn off the amplifier; a front audio port connected to the amplifier to receive amplified analog audio signals generated by the amplifier; and a rear audio port connected to the amplifier and the control circuit to selectively receive the amplified analog audio signals or the digital audio signals. The control circuit and the front audio port are turned off when the rear audio port is connected to an analog system, and the amplifier and the front audio port are turned off when the rear audio port is connected to a digital system. | 11-13-2008 |
