    摘要: A jet engine nozzle having a pair of pivoting extension arms and a pair of pivoting shells connected to a jet pipe is provided. The first extension arm is pivotally connected to the jet pipe at a first location, while the second extension arm is pivotally connected to the jet pipe at a second location. Each shell is pivotally connected at both the first and second locations. An axis of rotation associated with the first location is coaxial to an axis of rotation associated with the second location. Independent actuation means are provided to rotate the extension arms and the shells, thereby enabling adjustment of the thrust-vector angle or the exhaust area of the nozzle.

    摘要: A method of decoding an encoded bitstream. The method includes performing a table lookup. Addresses into the table are generated using selected numbers of bits drawn from the bitstream in response to values stored in the table entries. A table entry may contain an index offset and a number of bits to extract from the bitstream. Alternatively, the table entry may contain the decode result. The value of a result tag in the entry signals which of the alternatives is contained in the entry. The table is recursively accessed until a portion of the bitstream is decoded. Any remaining portion of the bitstream is decoded similarly. An initial index into the table is determined from a number of bits of the bitstream corresponding to the length of the smallest code word in the codetable used to encode the bitstream.

    摘要: Digital tone controls 500 include a first path 502 including a digital filter 504 and a scaler 505 for controlling a level of a low frequency component of a received digital audio signal. A second 502 includes a digital filter 504 and a scaler 505 for controlling a level of a high frequency component of the received digital audio signal. A third path 503 includes a scaler 506 for controlling a level of an unfiltered component of the received audio signal. A summer 507 adds a contribution from each of the paths to generate a composite signal having a selected gain-frequency response.

    摘要: A multi-channel digital audio decoder which receives an encoded audio signal having at least two channels and which decodes the audio signal. The digital audio decoder includes an input, which receives the encoded audio signal and a processor, which receives the encoded audio signal from the input. The processor decodes the encoded audio signal and provides decoded digital audio data. Also included is a buffer, which receives the decoded digital audio data from the processor. The buffer has a first-channel portion and a second-channel portion which have unequal sizes.

    摘要: An integrator stage for use in a delta sigma modulator includes an operational amplifier, an integration capacitor coupling an output of the operational amplifier and a summing node at an input of the operational amplifier, and a feedback path. The feedback path includes first and second capacitors having first plates coupled electrically in common at a common plate node and switching circuitry for sampling selected reference voltages onto second plates of the capacitors during a sampling phase. The integrator stage further includes a switch for selectively coupling the common plate node and the summing node during an integration phase.

    摘要: A lamp fixture includes a light emitting diode supported on a front surface of a printed circuit board. A reflector and heat sink includes a rear surface disposed adjacent the front surface of the printed circuit board and an opposing reflective surface defining a reflector dish. An aperture through the reflector and heat sink allows the light emitting diode to extend from the printed circuit board into the reflector dish. An epoxy lens is disposed over and seals the reflector surface and the light emitting diode. A assembly including a base and an inner casing extending from the base supports the printed circuit board and the reflector and heat sink. An outer casing encloses the inner casing and includes an aperture for outputting light transmitted through the epoxy lens from the light emitting diode and the reflective surface.
