Abstract: An apparatus, method, and system for a low current led fixture internal auxiliary power supply capable of supplying a low DC voltage output on the order of 1-50 VDC from a voltage input ranging from 15 VDC to 1000 VDC.

Abstract: A self-healing overtemp circuit is described and illustrated comprising a temperature sensing circuit, a voltage sensing circuit, and optionally, a current sensing circuit. The self-healing overtemp circuit is designed to ramp down power in an LED lighting system (or other electrical circuit) in response to a sensed or impending thermal runaway (and optionally, overcurrent) event. Said thermal runaway and overcurrent events may be a result of failure of one or more components (e.g., driver, active cooling means) of the lighting system. The self-healing overtemp circuit further comprises means of restoring power to said LEDs in a manner that avoids (i) a perceivably bright flash of light or (ii) increased risk of component failure.

Abstract: A system, apparatus, and method for operating one or more drivers of light sources, such as can be used with LED lighting fixtures, wherein main power to the drivers is galvanically isolated from communication functionalities to and from the drivers. In one example, a controller can receive information or send information to the drivers in a galvanically isolated manner. The galvanic isolation can be accomplished in different ways and configurations for high flexibility of design.

Abstract: A high definition television transmitting system includes a source of high definition analog RGB video signals which are converted to corresponding digitally encoded signals and thereafter compressed by a video encoder to a six megahertz bandwidth. The compressed data is formatted by a transmitter and processed in accordance with a Reed-Solomon error control system for broadcast as an NTSC-type broadcast signal. A high definition television receiver includes a high definition signal receiver coupled to the transmitter by a transmission link. The receiver extracts the compressed video, audio and ancillary data signals and applies a Reed-Solomon error correction thereto. The compressed video data is reconstructed by a video decoder and processed for high definition display.

Abstract: An adaptive comb filter and interpolator is combined with scan conversion circuitry thereby to reduce requirements for memory storage. Scan rate conversion processing of received television signals is coupled with adaptive comb filtering and interpolating to allow for all of the separate processes to be accomplished utilizing combined circuitry and a single memory using less memory storage space than the sum of the memory that the separate functions would normally require when performed at separate or discrete portions of a television receiver circuitry. A predetermined number of lines are stored in a memory and written out to combing and interpolating arithmetic logic circuitry under the control of a separate control circuit. The control circuit addresses the memory to provide for separately reading in the received digitalized video information and writing out the scan converted information to the logic circuitry for combing and interpolating.
