| 20100226653 | CIRCUIT FOR SWITCHING SIGNAL PATH, ANTENNA MODULE AND RADIO OVER FIBER SYSTEM - A circuit for switching a signal path includes a path selection element, a detector, a switch, and a control circuit. A first end and a third end of the path selection element are coupled to the detector and the switch, respectively. The switch is normally in a conductive status for outputting an upload signal through the path selection element and the switch when the upload signal is input from a second end of the path selection element. When a download signal is transmitted to the detector, the detector transmits the download signal to the path selection element and enables a detection signal. The control circuit switches the switch status to an open-circuit status for outputting the download signal isolated by the switch from the second end of the path selection element. Until the download signal is transmitted completely, the control circuit switches the switch status to the conductive status. | 09-09-2010 |
| 20110026932 | Head-End Circuit and Remote Antenna Unit and Hybrid Wired/Wireless Network System and Transceiving Method Using Thereof - A head-end circuit comprises first and second continuous light sources, first and second modulators. The first and the second continuous light sources provide first and second optical signals respectively corresponding to first wavelength and second wavelength, which is different from the first wavelength. The first modulator modulates the first optical signal based on first clock signal to generate an optical clock signal. The second modulator modulates the second optical signal based on downlink data to generate optical downlink data with the carrier of the second optical signal. The optical clock signal and the optical down link data are outputted to a remote antenna unit via first fiber path. | 02-03-2011 |
| 20110110667 | OPTICAL NETWORK AND OPTICAL SIGNAL MODULATION METHOD THEREOF - An optical network and an optical signal modulation method thereof are provided. The optical network includes an optical fiber and a remote node (RN). The RN receives a continuous carrier wave from the optical fiber and modulates the continuous carrier wave to generate a first frequency offset carrier wave The frequency of the first frequency offset carrier wave is different from that of the continuous carrier wave. A first user device re-modulates and loads data to the first frequency offset carrier wave to generate a first upstream signal. The frequency of the first upstream signal is the same as that of the first frequency offset carrier wave. The RN inputs the first upstream signal into the optical fiber. | 05-12-2011 |

| 20100309295 | 3D VIDEO PROCESSOR INTEGRATED WITH HEAD MOUNTED DISPLAY - A 3-D stereo video device that includes a headset housing that incorporates a 3-D video processor chip, video display driver circuitry, micro-displays and optics such that the only required external component is a joystick or other user input device. By utilizing a direct digital video interface between the video processor chip and the video driver chip, the need for video signal encoder/decoders, digital to analog converters, video up-converters and other similar complicated circuitry to handle remotely generated analog video signals are eliminated. The design not only saves cost but also allows for a higher resolution, higher frame-rate video presentations than previous designs. | 12-09-2010 |

| 20110049128 | Heating Pad With Temperature Control And Safety Protection Device - A heating pad is provided. The heating pad includes a heating element and a control circuit operatively connected to the heating element for providing a predetermined level of power thereto. An isolation device interconnects a power source to the control circuit. The isolation device has a first open configuration preventing transmission of electrical power therethrough and a second closed configuration allowing transmission of electrical power therethrough. The control circuit terminates power to the heating element in response to the heating element exceeding a first temperature limit. The isolation device moves from the closed configuration to the open configuration in response to the heating element exceeding a second temperature limit. | 03-03-2011 |
