| 20110281531 | RADIO COMMUNICATION TRANSCEIVER - A radio communication transceiver includes a transformer, a switch, a power amplifier (AP), and a low noise amplifier (LNA). The transformer has a primary winding and a center-tap secondary winding, the primary winding has a first endpoint and a second endpoint, and the center-tap secondary winding has a first endpoint, a second endpoint, and a third endpoint. The switch has a gate, a drain, and a source, in which the gate receives a control signal (CS), the drain is connected to the second endpoint of the primary winding of the transformer through a coupling capacitor, and the source is grounded. The PA has at least one output terminal connected to the first endpoint and the second endpoint of the center-tap secondary winding of the transformer. The LNA has an input terminal connected to the second endpoint of the primary winding of the transformer. | 11-17-2011 |

| 20110231186 | SPEECH DETECTION METHOD - A speech detection method is presented, which includes the following steps. A first voice captured device samples a first signal and a second voice captured device samples a second signal. The first voice captured device is closer to a speech signal source than the second voice captured device. A first energy corresponding to the first signal within an interval is calculated, a second energy corresponding to the second signal within the interval is calculated, and a first ratio is calculated according to the first energy and the second energy. The first ratio is transformed into a second ratio. A threshold value is set. It is determined whether the speech signal source is detected by comparing the second ratio and the threshold value. | 09-22-2011 |
| 20110074343 | WIRELESS COMMUNICATION MODULE - A wireless communication module includes a radiation unit, a battery, and a communication unit. The radiation unit has an antenna and a rectifier, in which the antenna is used to receive a radio frequency (RF) signal, and the rectifier converts the RF signal and outputs a voltage signal. The battery receives the voltage signal, and accordingly stores an electrical energy. The communication unit is electrically connected to the battery, and is powered by the electrical energy. When the wireless communication module is applied to a communication device, the RF signal is used as a source of an electrical power, and as the radiation unit and the communication unit are integrated into a system on chip (SOC), an overall volume of the communication device is effectively reduced. | 03-31-2011 |
