Abstract: Disclosed herein is a circuit for determining failure of a movable MEMS mirror. The circuit includes a mirror position sensor associated with the movable MEMS mirror and that generates an analog output as a function of angular position of the movable MEMS mirror. An analog to digital converter converts the analog output from the mirror position sensor to a digital mirror sense signal. Failure detection circuitry calculates a difference between the digital mirror sense signal at a first instant in time and the digital mirror sense signal at a second instant in time, determines whether the difference exceeds a threshold, and indicates failure of the movable MEMS mirror as a function of the difference failing to exceed the threshold.

Abstract: A device disclosed herein includes a feedback measuring circuit to measure a signal flowing through a movable MEMS mirror. Processing circuitry determines a time at which the signal indicates that a capacitance of the movable MEMS mirror is substantially at a maximum capacitance. The processing circuitry also determines, over a window of time extending from the time at which the signal indicates that the capacitance of the movable MEMS mirror is substantially at the maximum to a given time, a total change in capacitance of the movable MEMS mirror compared to the maximum capacitance. The processor further determines the capacitance at the given time as a function of the total change in capacitance, and determines an opening angle of the movable MEMS mirror as a function of the capacitance at the given time.

Abstract: A receiver for receiving an incoming signal over a communication medium includes an echo canceller, which is adapted to receive an outgoing signal transmitted over the communication medium, and to process the outgoing signal using a set of variable processing coefficients in order to generate an echo cancellation signal. A summer combines the incoming signal with the echo cancellation signal so as to generate an echo-cancelled signal. An equalizer applies an equalization operation to the echo-cancelled signal so as to generate an equalized signal. A residual echo cancellation circuit processes the equalized signal so as to adaptively update the variable processing coefficients of the echo canceller.

Abstract: A solid state image sensor has an array of pixels formed on an epitaxial layer on a substrate. Each pixel is relatively large so that it has a high light collecting ability, such as 40-60 nullm, but the pixel photodiode is relatively small so that it has a low capacitance, such as 4-6 nullm. Active elements of the pixel photodiode are formed in wells that are spaced away from the pixel photodiode so that the latter is surrounded by epitaxial material.

Abstract: An image sensor includes pixels which are of the four-transistor, PIN photodiode type. In each pixel, the charge on a photodiode is transferred by a transfer gate to a sensing node. Readout of reset and read voltages is via an amplifier. A gain capacitor is connected in feedback across the amplifier. Read and reset gates are controlled so that the pixel is reset to a virtual ground voltage controlled by the gain capacitor. This is independent of the pixel parasitic capacitance.

Abstract: An active pixel array has the signal output of each pixel connected to a first column conductor, and a reset switch connected to a second column conductor. The first and second column conductors are connected to a read-reset amplifier. The read-reset amplifier operates in a first mode in which a reset voltage is applied to the second column line, and in a second mode in which pixel output signals are buffered from the first column line. The read-reset amplifier can also operate as a comparator forming part of an ADC circuit.

Abstract: A method for efficient low power motion estimation of a digital video image is provided in which processing requirements are reduced based upon the content being processed. The method performs motion estimation of a current video image using a search window of a previous video image. The method may include forming mean pyramids of a reference macroblock and the search area and a full search at a lowest resolution. A number of candidate motion vectors (CMVs) propagated to lower levels may be dependent on a quantized average deviation estimate (QADE) of a current macroblock and the maximum distortion band obtained during training for that QADE value at that particular level. Training over a sequence may be triggered at the beginning of every sequence. This training technique may be used to determine the value of the maximum distortion band for all QADEs of the macroblocks occurring over the training frames.
