Patent EP-0455518-A2 (EP)
Inventor: SINGHAL SANJAYA
IPC: G01R11/24
Filed: 1991-05-07
Abstract: An apparatus and method is disclosed for measuring the consumption of electricity from a mains supply which is either single or multi-phase. The apparatus and method of the invention is also able to detect when tampering with connections to the supply occurs as for instance, may be done in an attempt to reduce the quantity of energy registered as having been used. 
     In a meter which takes as inputs signals indicative of the voltage and currents present in the supply a tamper is registered whenever the voltage reading, for instance in one phase of the three-phase supply, is absent while the corresponding current is present. If both voltage and current are absent this is not registered as tampering but may be noted as a fault in the system.

Abstract: An improved method of using an ID saw slicing machine (1) for slicing a single crystal ingot (6) in a direction normal to the axis of the ingot (6) to obtain wafers, of which the improvement lies in that the cutting load which the blade (2) of the ID saw slicing machine (1) imposes upon the single crystal ingot (6) is continually detected in terms of three vector elements along three mutually perpendicular directions throughout the slicing operation, and that, when the magnitude of that vector element of the cutting load which extends in the slicing direction exceeds a predetermined value, the feed rate of the ingot (6) to the blade (2) is decreased and, at the same time, the rotational speed of the blade is increased in accordance with a predetermined control pattern.

Abstract: A digital-to-analog converting unit decodes a digital input signal into a decoded signal, and selectively allows constant-current cells (C11 to C7m) arranged in matrix to supply unit currents for producing an analog output signal, wherein a decoding circuit (12b) incorporated in the digital-to-analog converting unit sequentially selects the constant-current cells in such a manner that insufficient increment of current produced by one of the constant-current-cells (C51) cancels out excessive increment of current produced by another constant-current cell (C31) so that the analog output signal is improved in linearity.

Abstract: A method for optimal discrete rendering of images is disclosed. The present invention provides a technique for efficiently converting an original sampled image into a bitmap suitable for a specific output device. The method includes explicit printer and perception effects, and employs local permutations of bits, to find optimal bit settings. A continuous-tone image is first sampled to form a sampled image (12), through which a series of swaths are defined. For each swath (14i) in turn, an iterative procedure examines a column of bits (16) at a time, determining which configuration of the column of bits yields a minimal local difference value between the trial bitmap and the sampled image. While holding the rest of the trial bitmap constant, the column of bits is permuted and the difference value calculated, for each configuration of the column's look-ahead bits (22). To determine the difference values, local printer (17a) and perception (17b) models calculate effects between bits, while a local comparison model calculates the difference between the trial bitmap and the sampled image. The printable bitmap resulting from the methods of the present invention can be displayed by the output device to provide a faithful duplication of the original image.

Abstract: An image signal processing device according to this invention is a device for processing an image signal. The device is arranged to input digital data corresponding to two kinds of color-difference signals in synchronism with a clock signal corresponding to a data rate of the digital data, reconstruct the inputted digital data corresponding to the two kinds of color-difference signals into digital data synchronized with a clock signal having a frequency which is an integer multiple of a color subcarrier frequency, and form digital data corresponding to a chrominance signal by using the reconstructed digital data corresponding to the two kinds of color-difference signals. Accordingly, it is possible to stably encode the two kinds of color-difference signals into the carrier chrominance signal by means of a simple construction without degrading the color-difference signals.

Abstract: A flexible tape such as TAB or FLEX tape (1) having conducting leads (5) extending in cantilevered fashion over an edge of a dielectric layer (3) preferably a flexible dielectric layer. A photosensitive dielectric coating (2) is disposed on the part of the leads which lie on the dielectric layer. The protective dielectric coating (7) is aligned to the edges of the dielectric layer by a self aligning technique. A liquid polymer is disposed on the dielectric layer. The protective dielectric layer prevents the formation of conductive dendrites bridging adjacent conductors. Without this protection dendrites form between adjacent conductors held at different potentials because of residual water on the dielectric layer which acts as an electrolyte resulting in metal being plated from one line onto another line which builds up as a dendrite which eventually shorts adjacent lines.

Abstract: A multiple serial access memory is provided. A dynamic random access memory (30) is addressed to input data thereto and output data therefrom. Rows of data are output from the array (50) in response to address signals (34, 36, 38) provided thereto. A plurality of serial output ports (44, 46, 48) is coupled to the output of the array for selectively latching different rows of data output from the array. The serial output ports (44, 46, 48) are clocked to output the latched data therefrom. In an illustrated embodiment, each of the serial output ports contains a shift register (62, 64, 66, ... 68) having a length equal to the width of the memory array (30). The shift register is responsive to a first timing signal (42, 52) for latching a row of data from the array (30). A second timing signal actuates the shift register to shift a row of latched data. A serial access selector (70) coupled to the shift register outputs a selected portion of the shifted data from the serial output port. The memory has particular application as the frame store for a motion compensated interframe image coding/decoding system.

Abstract: Vehicles having implements are typically used to perform repetitive functions in work cycles. An implement control system raises and lowers an implement relative to the vehicle and reduces the stresses applied to the vehicle from abruptly stopping the motion of the implement. A lever pilot signal is produced in response to the pivotal position of a control lever. An electrohydraulic pilot signal is also produced. The pilot signal having the greater pressure is directed to a main valve for controlling the position of the implement. The method and apparatus of the instant invention are applicable to a number of vehicles having a hydraulically operated implement.

Title: Disk drive

IPC: G11B7/085
Filed: 1992-10-15
Abstract: In a disk drive such as optical disk recorder, during the sensing of closely-spaced, position-indicating, machine-sensible indicia, a first peak of a track error signal (110, 110′) is detected. In response to the first peak being detected, a half-track counter (132, 132′) is decremented from a value which depends upon the position of the destination track relative to a current track. In response to the occurrence of a selected value of the half-track counter and the presence of a zero crossing of the tracking error signal, a first timer (138, 138′) is activated to mask any defects occurring during the selected first half cycle of the last cycle of the tracking error signal. The half-track counter is again decremented in response to a second peak being detected and the occurrence of a next-to-last zero crossing of the tracking error signal and a second timer (144) is then activated to mask any subsequent defects occurring during the second half cycle of the tracking error signal. The seek operation is terminated when the count value in the half-track counter equals zero and a final zero crossing is detected. Thereafter, a track following operation is activated.
