Title: Validation of optical ranging of a target surface in a cluttered environment.
Inventor: BLAIS FRANCOIS
IPC: G01S17/89
Filed: 1993-08-06
Abstract: To provide a system for the optical ranging of a selected point on a target surface irradiated with light while avoiding false signals from other sources in a cluttered environment, the system employs a combination of the triangulation ranging technique with the Biris ranging technique, i.e. imaging onto a position sensitive photodetector through an apertured mask. This combination enables the respective equations for range that apply to the respective techniques to be combined to generate an equation that is true only for target surface points that are directly on the light beam, hence enabling rejection of false signals on the basis of those that fail to satisfy this latter equation. The system has the advantage of flexibility, in that it permits the light beam to be directed onto the target surface from a wide range of locations relative to the detector. In addition, three dimensional data on the target surface can be obtained by using at least one further light beam inclined to the first beam and a mask with more than two apertures. For many practical applications this latter arrangement avoids a need to scan the target surface relative to the detector.

Title: Adaptive rematrixing of matrixed audio signals.
Inventor: DAVIS MARK FRANKLIN
IPC: H05H5/00
Filed: 1993-10-08
Abstract: In a system in which a low-bit rate encoder and decoder carries matrixed audio signals, an adaptive rematrix rematrixes matrixed signals from an unmodified 4:2 matrix encoder to separate and isolate quiet components from loud ones, thereby avoiding the corruption of quiet signals with the low-bit-rate coding quantization noise of loud signals. The decoder is similarly equipped with a rematrix, which tracks the encoder rematrix and restores the signals to the form required by the unmodified 2:4 matrix decoder. The encoder adaptive rematrix selects the matrix output signals or the amplitude weighted sum and difference of the matrix output signals. The choice of whether the matrix output signals or the sum and difference of the matrix output signals are selected is based on a determination of which results in fewer undesirable artifacts when the output audio signals are recovered in the decoder. The adaptive rematrix may operate on frequency component representations of signals rather than the time-domain signals themselves.

Abstract: The circuit comprises a variable gain amplifier (VCA) (71) supplied with a process signal (S55), a signal processor (72-74) for detecting and calculating the level of either the process signal or an output signal of the VCA and the level of a control signal (S56), and outputting a gain control signal (S60) in accordance with the level difference between them. A voltage output type amplifier (77) is switchable to either a normal operating state for delivering at its output terminal the gain control signal obtained from said signal processor or a signal interrupting state for retaining said output terminal at a high impedance state. A converter (78) converts the output voltage of the amplifier (77) into a current and voltage holding means (75) generate a voltage proportional to the current supplied thereto from the converter (78). The VCA (71) amplifies the process signal according to the output voltage of the voltage holding means (75). 
     The servo circuit is adapted for controlling a variable gain amplifier to process an audio signal in a television receiver, a stereo apparatus or the like. When the servo circuit is formed into an IC configuration, a high-precision operating characteristic is attained merely by a bipolar-transistor manufacturing process to consequently minimize the number of required process steps, hence curtailing the production cost.

Abstract: A scene based nonuniformity correction method (40) that computes and applies offset correction errors to a video signal corresponding to an image derived from a imaging sensor (11). A video signal derived from the sensor (11) is processed such that a vector representing offset correction terms is formed, and this vector is initially set to zero. Each element in this vector represents a correction term for a particular detector of the sensor (11). The vector is applied to each pixel of the image by a processor (13) as the pixels are read from the sensor (11). To measure the offset error, the image is separated into vertically oriented regions, each comprising a plurality of channels. The average of each channel within a region is computed (42), and a set of region vectors is formed, such that there is one region vector for each region. Each region vector is then globally high-pass filtered and then edges larger than a predefined threshold are detected (43), and marked (44). Then, each region vector is further separated into sub-regions (45). The isolated sub-regions are locally high-pass filtered. In one embodiment, the correction terms for each vertical region vector are averaged together, resulting in a single correction vector (48). The correction terms calculated for each vertical region may also be applied individually to each detector of the sensor (11). In this second embodiment, the offset level error in each region for each channel is calculated (49), wherein the offset level error at boundary edges is undefined. The correction terms corresponding to a region are applied as the detector (11) scans the scene and views a portion corresponding to that particular region. The correction terms are smoothed at region boundaries to eliminate noise due to boundary transitions.

Abstract: A method of observability characterization for data posts in a digital terrain elevation data structure is obtained by calculating intervisibility with respect to surrounding data posts within a given radius. By then summing the number of data posts within this radius and visible to the data post of interest, an observability value may then be associated with the data post of interest. This observability value represents observability generally with respect to surrounding terrain as a whole, not with respect to a specific other point in the database. In this manner, terrain may be evaluated for observability generally in, for example, route selection procedures where observability plays a role.
