Patent number: 8952795Abstract: A circuit for providing signal amplification with reduced fixed pattern noise. In an embodiment, the circuit includes an amplifier and a plurality of legs coupled in parallel with one another between a first node for an input of the amplifier and a second node for an output of the amplifier. Control logic selects a first combination of the plurality of legs for a first configuration of the circuit to provide a first loop gain with the amplifier. In another embodiment, the control logic further selects a second combination of the plurality of legs for a second configuration of the circuit to provide a second loop gain with the amplifier, wherein the first loop gain is substantially equal to the second loop gain.Type: GrantFiled: September 6, 2012Date of Patent: February 10, 2015Assignee: OmniVision TechnologiesInventors: Zhihao Xu, Guangbin Zhang

Patent number: 7551059Abstract: A hybrid image sensor includes an infrared detector array and a CMOS readout integrated circuit (ROIC). The CMOS ROIC is coupled to at least one detector of the IR detector array, e.g., via indium bump bonding. Each pixel of the CMOS ROIC includes a first, relatively lower gain, wide dynamic range amplifier circuit which is optimized for a linear response to high light level input signals from the IR detector. Each pixel also includes a second, relatively higher gain, lower dynamic range amplifier circuit which is optimized to provide a high signal to noise ratio for low light level input signals from the IR detector (or from a second IR detector). A first output select circuit is provided for directing the output of the first circuit to a first output multiplexer. A second output select circuit is provided for directing the output of the second circuit to a second output multiplexer.Type: GrantFiled: December 16, 2005Date of Patent: June 23, 2009Assignee: Goodrich CorporationInventor: Michael Farrier

Patent number: 7006792Abstract: A portable wireless andon communication system and method for use in manufacturing, assembly and other industrial settings. A transmitter station and receiver station are set up for immediate use by simply connecting each to a standard power source. A user needing assistance manually activates a switch at the transmitter station, thus turning on a light and transmitting a corresponding signal to the receiver station. The receiver station receives the signal and turns on a corresponding light and tone generator. The tone generator and light alert indicate to the proper parties the request for a response. A responding party scans transmitter stations for the corresponding light and provides assistance. The switch may be a sensor activated by a change in state indicating that assistance is required. The portable system is easily reconfigured if necessitated by layout changes in a manufacturing line.Type: GrantFiled: September 26, 2002Date of Patent: February 28, 2006Inventor: Robert H Wilson
