Abstract: The invention provides a method and apparatus for performing image data compression. Initially, a two-dimensional block of image data in a spatial domain is transformed by a transform coder, resulting in a two-dimensional array of activity coefficients in a frequency domain. The array is then serialized and quantized, yielding a one-dimensional array of coefficients with a leading coefficient and an original trailing coefficient. Next, a portion of the array is selected by choosing a new trailing coefficient based on a setable ratio of the energy of the new short array to the energy of the original array. Lastly, an end-of-block symbol is appended after the new trailing coefficient, and the selected portion of the array is encoded using an entropy coder. The invention allows image data to enjoy enhanced compression with good image fidelity, and allows image fidelity to degrade gracefully in trade for higher degrees of image compression.

Abstract: Suppose that a plurality of elements e.g. logic devices are to be arranged in a pattern (array). Then, there are several predetermined relationships between those elements, e.g. interconnection relationships, functional relationships etc. First elements are input (11) and the elements are arranged according to one of one relationships (e.g. interconnection) by a basic arrangement processing part (14). 
     This produces an intermediate pattern. Then the intermediate pattern is investigated by an arrangement modification part (15) and the intermediate pattern is re-arranged according to one or more of the other arrangement relationships (e.g. function). The rules for this re-arrangement may be stored in an arrangement modification rule storing part (16) . The resultant pattern may then be displayed (12) e.g. by printing. In this way, it is possible to generate a pattern in which the relationship between the elements are clearly displayed. Means (154) may also be provided to enable a device according to the present invention to derive one or more further rules from a revised pattern input by a user.

Abstract: A system and method are provided in a graphics envirgnment for ensuring that a line drawn upon the surface of a polygon is always visible to a user of the graphics system. In a Z-buffered environment the range of depth values contained therein are set to the 75% of the total capacity which is considered closest to the surface of a display screen. The line is then drawn into this 75% set of Z-buffer depth values. A shift is then computed, based upon the normal to the polygon in device coordinates. This shift is then added to the previously set 75% range of Z-buffer depth values. The polygon is then drawn at a depth equal to the previously set range plus the shift. Thus, the line will always be visible since, the polygon surface will always be considered by a graphics adapter to deeper than the line contained on the surface thereof.

Abstract: Semi-prepared products containing flour have hitherto been made stable by deep freezing. A new process of bacterial reduction is to be developed which enables these products to be put into interim storage with normal cooling without significantly changing them. A suspension is prepared from flour and a liquid, such as water, eggs and/or milk, which is treated for 5 to 240 minutes with a gas to which it is inert such as carbon dioxide at a pressure between 2 and 100 bar. In this way, all bacteria are significantly reduced, so that instead of deep-freezing, storage in a refrigerator until the finishing processing of the semi-prepared product is adequate. The process is suitable for all mixtures containing flour and a liquid, and leads to no contamination of the semi-prepared product.

Abstract: This disclosure sets forth a dot matrix printer having an improved ribbon drive. The ribbon drive is provided by two respective stepper motors. When one stepper motor is in a take-up mode, the second is in a feed mode. The process is reversed proximate the end of the tape as it is unwound. A re-generative mode for the feed motor is provided and a resistance bank varies amounts of drag on the ribbon as it is fed from the feed motor spool. Both motors when in the take-up mode are driven by full H bridge drivers and amplifiers controlled by a micro controller through an address and decode input and output latch. In order to provide for a uniform velocity of the print ribbon the angular velocity of the take up motor is controlled by counting the zero crossings of the feed motor, and then loading it into the micro controller to compare it with a look-up table for purposes of providing a proper speed to the take-up motor and the proper peak drag through the resistance bank to the feed motor. All functions are controlled by the micro controller and firmware logic provided thereto.

Abstract: Herein disclosed is a method and a system for recording and reproducing digital audio signals which enable simultaneous recording of video signals and audio signals without a synchronous relation, and simultaneous reproducing rerecorded audio signals if a part of channels of the audio signals are rerecorded, since a sample number of the audio signals for each the channel is equal to each other. On rerecording, a modulator 113 demodulates signals and the demodulated signals are separated into audio signals and sample number discriminating signals of the audio signals by a demultiplexor 114. A second counter changes dividing number on the basis of the sample number discriminating signals separated by the demultiplexor 114. A phase comparator 118 compares a phase of a cycle of the second counter 117 and a phase of a video frame cycle. Output signals are limited their band by a low-pass filter 119 and controls an oscillated frequency of a voltage controlled oscillator (VCO) 120. A second switch 106 selects output clock pulses of the VCO so that clock pulses used for A/D conversion are coincided with reproduced clock pulses. A fourth switch 110 selects output signals of a delaying means 115 so that sample number of recorded audio signals and sample number discriminating signals are coincided with reproduced audio signals.
