    摘要： A method and an apparatus for encoding an image signal. The apparatus includes an acquisition module disposed to receive the image signal. A first processor is coupled to the acquisition module. At least one encoder processor is coupled to the first processor. The at least one encoder processor produces an encoded image signal under control of the first processor. The method includes the steps of converting an input image signal into a predetermined digital format and transferring the digital format image signal to at least one encoder processor. The method further includes the step of applying, at the at least one encoder processor, a hierarchical vector quantization compression algorithm to the digitized image signal. At the next step, a resultant encoded bit stream generated by the application of the algorithm is collected. The method and apparatus of the present invention may be used in conjunction with an ordinary modem to transmit and/or receive audio, video sequences or still images.

    摘要： A technique for efficiently utilizing memory in determining a next state accumulated cost in a communications system or a Viterbi decoder. The system includes a memory having an array of registers. A first present state accumulated cost is retrieved from a first storage register of the array. A second present state accumulated cost is retrieved from a second storage register of the array. A first next state accumulated cost is calculated based on the first present state accumulated cost. The first next state accumulated cost is stored in the first storage register of the array. An advantage of the invention is that such a technique requires less memory to calculate and store accumulated costs. The number of memory locations required is one for each individual state, which is substantially half of the memory locations required previously.

    摘要： A workpiece is supported by work support means (40; 40'; 40"; 44'; 142, 144) for movement in a first direction by co-operating workpiece clamping and feeding means (46; 142, 144), both said means being supported on a carriage (16) for movement in a second direction normal to the first to move a workpiece relative to a sewing machine head. Both of said means are arranged on both sides of an elongated aperture (42) extending in the second direction in alignment with a needle penetration point (N). Stepping motors (24; 60) are provided for moving the carriage (16) and operating the workpiece clamping and feeding means (46; 142, 144) under programmed control. A camera (70) is also provided aligned with the aperture 42, for detecting the peripheral outline of a workpiece fed therebeneath. Computer means is effective, in response to the detected outline, to identify the workpiece type and its orientation and location on the workpiece support means and accesses an appropriate stitch pattern data file and modifies the data to take account of the workpiece orientation and location. The workpiece is then sewn according to the thus modified data.

    摘要： A handle, for the female half of a quick-action coupling of the type including a body having a first end adapted to receive a hose and a second end adapted to receive the male half of the coupling, a grasping means coupled to the body for releasably grasping the male half of the coupling when inserted into the second end of the body, and a spring-biased slide member coupled to the body and co-acting with the grasping means for causing a locking engagement between the male and female halves. The handle comprises a housing having an interior opening in a first end thereof dimensioned so as to receive the female half of the coupling therein in a loose-fit sliding manner. The housing has a first interior annular portion remote from the first end for engaging the body of the female half of the coupling so as to push the female half of the coupling towards a corresponding male half of the coupling, without impeding movement of the slide member relative to the body, and a second interior annular portion for engaging the slide member so as to slide the slide member within the interior opening relative to the body when the user pulls the housing away from the male half of the coupling.

    摘要： A door latch mechanism, such as for a calculator battery enclosure, has a pair of ridge and groove mating points. The mechanism has a partially engaged position in which only a single ridge engages a groove and a fully engaged position in which both ridges engage grooves. A shock to the calculator, such as by dropping it, will generally not release the mechanism to a disengaged position. Consequently, the batteries will be retained and memory functions thereby preserved.

    摘要： An autogenerating apparatus provides secondary intense relativistic current beam pulses in response to an injected beam pulse. One or more electromagnetic energy storage devices are provided in conjunction with gaps along a beam propagation path for the injected beam pulse. For injected beam pulses which are no longer than double the transit time of electromagnetic waves within the storage devices (which may be resonant cavities), distinct secondary beam pulses are generated by each of the energy storage devices. The beam propagation path, together with the one or more gaps provided therein, operates as a pulse forming transmission line cavity, in which the separate cavities associated with the gaps provide delays for electromagnetic waves generated at the gaps. After doubly traversing the cavity, the electromagnetic waves cause the gap to generate the secondary beam pulses, which are thus delayed by a time interval equal to the double transit time for the induced wave within the cavity.

    摘要： Method and apparatus for controlling the operation of a grinding machine of the type comprising a circular grinding wheel adapted to rotate about its axis and a spindle adapted to hold a workpiece at a position radially spaced from the grinding wheel. The grinding machine includes slide means for advancing the grinding wheel into the workpiece, such means being powered by a threaded shaft and boss arrangement, and "jump-on" gauge means for measuring the diameter of the workpiece and providing an electrical output signal which is used to control feedrate. Feedrate is determined by a microprocessor which is connected to receive the gauge signal and to produce a feed program which will produce a given final diameter in a given time.
