Patent number: 10380990Abstract: A vehicle includes an engine and/or powertrain producing noise that is audible in a passenger compartment of the vehicle when the engine and/or powertrain is running. An active noise control arrangement includes a first loudspeaker disposed within a passenger compartment of the vehicle. A digital signal processor receives audio data and transmits an audio signal to the first loudspeaker dependent upon the audio data. A microphone is disposed within the passenger compartment and converts the sound from the first loudspeaker and the noise within the passenger compartment into a microphone signal. The microphone signal is transmitted to the digital signal processor, and the digital signal processor modifies the audio signal such that the audio signal attenuates the noise in the passenger compartment.Type: GrantFiled: September 20, 2018Date of Patent: August 13, 2019Assignee: Panasonic Automotive Systems Company of America, Division of Panasonic Corporation of North AmericaInventors: Benjamin David Sweet, Richard Lawrence Cooper

Patent number: 9851771Abstract: Dynamic monitoring of current draw by a memory device or memory subsystem can enable a power management system to adjust a memory access performance parameter based on monitored power usage. The system can generate a power usage characterization for the memory device and/or memory subsystem based on monitoring current draw for a known pattern, and then subsequently use the power usage characterization to determine how to adjust the memory access performance parameter.Type: GrantFiled: December 28, 2013Date of Patent: December 26, 2017Assignee: Intel CorporationInventors: Lawrence A Cooper, Justin J Song, Xiuting C Man, Nagi Aboulenein, Christopher E Cox, Rebecca Z Loop

Patent number: 6867889Abstract: A holographic optical element (HOE) device is mounted in wireless optical telecommunication system transceiver. The HOE device includes a developed emulsion material having an interference pattern recorded thereon, sandwiched between a pair of elements, such as a pair of clear glass plates. In operation, the HOE device uses the recorded interference pattern to diffract received light rays towards an optical processing unit of the system receiver. A transmitter unit can be positioned at least in part behind the HOE device. An opening in the emulsion material allows a light signal transmitted from the transmitter unit to be substantially unaffected by the recorded interference pattern. The transceiver can also include a spotting scope and an alignment beacon.Type: GrantFiled: October 16, 2003Date of Patent: March 15, 2005Assignee: Terabeam CorporationInventors: Charles Gregory Amadon, Richard D. Rallison, Mark Pratt, David P. Bajorins, Lawrence Cooper Stapleton, Richard B. Riday, Harold Alexander Brown, William Joseph Lauby, Michael Thomas, Scott William Sparrold

Publication number: 20020140848Abstract: A chamber for a surveillance camera that is designed to be mounted inside a larger camera housing. The chamber is sealed and provides a controlled internal environment for sensitive camera optics and internal electronics. A flush mount window is provided for the front lens of the camera, and a sealed feed-through electronic connector is provided for attachment to external controls. Valves for both adding and removing gasses to/from the chamber are provided. In one embodiment, temperature, pressure and/or humidity sensors may be deployed inside the chamber and connected electronically to a display or computer for monitoring and adjustment. In another embodiment of, a heating element is provided to evaporate moisture from the camera lens and/or from the window, and to help control the temperature inside the chamber.Type: ApplicationFiled: March 25, 2002Publication date: October 3, 2002Applicant: PelcoInventors: Cliff Lawrence Cooper, Joshua Ryan Cockrum, Michael Timothy Higgins, Shane E.

Patent number: 4866408Abstract: A three phase hermetic protector for electrical apparatus has a pair of terminals extending through a header with first and second elongated heaters mounted on the terminals and extending away from the header. A rigid support is attached to the header between the terminals and extends away from the header and mounts a third elongated heater extending back toward the header. A snap acting disc is cantilever mounted on the free end of the third heater and mounts thereon a pair of movable contacts adapted to move into and out of the engagement with stationary contacts mounted at the free ends of the first and second heaters. The rigid support mounts a calibration screw beneath the free end of each of the first and second heaters to independently adjust the vertical position of the stationary contacts.Type: GrantFiled: October 28, 1988Date of Patent: September 12, 1989Assignee: Texas Instruments IncorporatedInventors: Jeffery J.
