Abstract: The invention serves to compress scalar data defined on a two-dimensional surface and to reconstruct the two-dimensional scalar data from the compressed data. It involves detecting edge lines (11-1, 11-2) of the scalar data (ø (i, j)), cutting a domain (12) on a horizontal line (17) intersecting with the edge lines (11-1, 11-2) and between the edge lines; determining a function (f (i)) as an approximation of a Laplacian of the two-dimensional scalar data at each point in the cut domain; compressing the two-dimensional scalar data ( ø(i, j)) by replacing the two-dimesional scalar data at every point with scalar data at the edge lines, (11-1, 11-2), scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the function determined above; and for reconstructing the two-dimensional scalar data based on the scalar data at the edge lines, scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the above function (f (i)).

Abstract: A belt buckle for vehicle safety-belt systems having a belt tensioner engaging on the belt buckle is equipped with a release button (12), into which a push-button (14) is integrated displaceably. The release button (12) carries a pivotably mounted blocking lever (20) which is pivoted when the push-button (14) is actuated, so that the release button (12) can move unimpeded past a stop part of the buckle housing (18). When, after the belt has been tensioned, the release button (12) endeavours, as a result of its mass inertia, to continue its movement to the end of the retensioning stroke, the blocking lever (20) nevertheless buts against the stop, so that a further movement of the release button (12) into its release position is prevented.

Abstract: An electric induction motor (10) is connected by a switch means (30) to a source (A, B, c) of three-phase alternating electricity. The speed of the motor is determined by detecting when the source voltage has made a zero crossing and thereafter sensing the polarity of the back emf voltage induced in each winding (11, 12, 13) of the motor when the switch means is non-conductive. After several zero crossings a set of polarity samples has been produced from each winding. A motor controller (20) determines the motor speed by detecting the occurrence of a predefined relationship among samples in each set. For example, the speed is in the range of fifty to about thirty-eight percent of full synchronous speed when three consecutive samples from one winding all have the same polarity. The occurrence of the predefined relationship among back emf polarity samples can be used to control the braking of the motor.

Abstract: The present invention aims at switching a plurality of input video signals without causing synchronization disturbance in the output video signal and with a reduced cost. In response to an input video signal switching directive supplied from a key switch (11), input video signal switching is performed in a vertical blanking interval after the field of the input video signal now being written has terminated. Simultaneously therewith, writing signals into a field memory (16) is inhibited during one field. During this time, horizontal and vertical synchronizing signals of the input video signals of the switching side are locked. Signals are written into the field memory recommencing during the next blanking interval of the input video signal of the switching side.

Abstract: A data processing system uses a machine-generated data structure (MGDS) to dynamically record and use the character recognition and repair histories of category fields on a document form. The MGDS includes a field data segment which has a coded data buffer portion and an error buffer portion for the extracted field image. Recognition coded data is entered into the coded data buffer portion and recognition error data is entered into the error buffer portion of the field data segment. Then subsequent repair processes can be applied to the recognition coded data by augmenting the MGDS with a repair segment for each character string which is repaired. A sequence of repair stages can be applied to a particular character string, each repair step adding another repair segment to the MGDS. At each stage of repair, the best estimate of the character string is placed into the coded data buffer portion of the field data segment. This enables the best estimate of the information content of the document field to be readily available for each stage of repair and for ultimate use in the data processing system.

Abstract: A method and apparatus (12) for relatively moving energy across an array of optical fibers. The energy may be scanned across the fiber array (20). A dielectric mirror (13) mounted on a galvanometer scanner is moved so as to cause successive pulses to irradiate different segments of the fiber optic array (20). As a result, each fiber receives radiation having sufficient fluence while reducing the energy per pulse (or the cw equivalent). Rather, than move the energy across the fiber array, the fiber array itself may be moved. One possible manner of movement is use of a piezo electric stack.

Abstract: Apparatus for decoding a stream containing codes of a variable length code (VLC) takes advantage of the fact that a trie representation of the VLC can be pruned to leaves that each represent a complete binary trie. Combinational circuits or ROMs are then employed to decode the pruned trie, thereby substantially reducing the complexity of decoding a VLC. In one embodiment the decoding problem is partitioned into segments by considering a few bits at a time, starting with the most significant bits. Each segment either outputs a valid code or informs the next segment that the decoding process is incomplete and provides information to assist the next segment in its decoding effort. In applications where the VL code can be selected for greater efficiency of the decoder, the offered VL code can be restructured to minimize the number of k-nodes, to thereby minimize the pruned trie, and to concomitantly minimize the sizes of the ROMs in the decoder.

Abstract: An active adaptive noise canceller (100) that inserts delays into the weight update logic of an adaptive filter to keep the filter stable. The noise and residual noise are sensed (102, 108) and the respective sensor signals are digitized at a given sample rate for processing in the adaptive filter (113). To eliminate the need for high sample rates while maintaining flexibility in the frequency regions over which the adaptive filter is stable, the delay (116) introduced into the weight update logic is a non-integer multiple of the sample period. The non-integer sample delay (118) is obtained by a sample interpolation and decimation procedure.

Abstract: A magnetoresistive read sensor based on the spin valve effect is described, in which a component of the read element resistance varies as the cosine of the angle between the magnetization directions in two adjacent magnetic layers (35,39). The sensor read element includes two adjacent ferromagnetic layers (35,39) separated by a nonmagnetic metallic layer (37). A layer (33) of nonmagnetic electrically conductive material is deposited adjacent to and in contact with at least one of the ferromagnetic layers (35) (referred to as a filter layer) to form a back or conduction layer (33) which provides a low resistance path for conduction electrons transmitted through the adjacent filter layer (35). The thickness of the filter layer (35) is selected such that it effectively blocks conduction electrons having spins antiparallel to the direction of magnetization in the filter layer (35) while allowing conduction electrons with parallel spins to be transmitted through the layer into the adjacent back layer (33). The magnetization of the filter layer (35) is free to rotate in response to an applied magnetic field thereby effectively varying the electrically resistance to conduction electrons in the back/filter layer. The thickness of the back layer (33) is selected to optimize the sensor parameters being measured and is in a range of about 4.0A to 1000A.
