Abstract: A computed tomography system corrects image errors resulting from misalignment of the fan beam (19,21,22) as a result of placement of the x-ray tube (26), thermal drift of the x-ray tube anode or mechanical stresses of the gantry or x-ray tube. Misalignment is determined alternately by means of a z-axis offset detector (30) which detects movement of the exposure area of the CT fan beam or a predictive model that calculates thermal drift or mechanical deflection of the focal spot of the x-ray tube based on previous use. The system includes a collimator (38,39,41) with a controllable x-axis position which may be controlled to reduce z-axis offset of the fan beam exposure area or to make the fan beam more parallel with the imaging plane of the CT system.

Patent EP-0533259-A2 (EP)
Inventor: HAEB-UMBACH REINHOLD DR
IPC: G10L15/32
Filed: 1992-09-11
Abstract: In recognising coherently spoken words, a multiplicity of hypotheses are usually set up which, during the recognition process, end in various words and then have to be continued with further words. To keep the number of words to be continued as small as possible, particularly with a large vocabulary, it is known to carry out an advance weighting over a limited period of time. According to the invention, it is proposed to use the same phonemes for the advance weighting as for the actual recognition and to add the difference sums obtained during the advance weighting to the weighting of the finished part-hypothesis which is to be continued, and to compare this sum with a threshold value which depends on the extrapolated minimum overall weighting at the end of the advance weighting period. This allows the search space for hypotheses to be continued to be restricted in a particularly advantageous manner. <IMAGE>

Abstract: An inter-field motion vector of an interlace scanned inputted image is detected, and, using the detected inter-field motion vector, movements between fields are compensated to constitute a frame, which is then subjected to block coding. Alternatively, an interlace scanned input image is subjected to two-dimensional block division and further an activity of each two-dimensional block is calculated, and, using the activity as an index, the two-dimensional block is divided into either field small blocks constituted by field data or frame small blocks constituted by frame data, and the divided small blocks are coded. By these steps, even the image having a large motion does not invite degradation of image quality, and high efficiency image coding can be realized.
Patent EP-0553588-A2 (EP)
Inventor: CARMON DONALD EDWARD
IPC: G06F9/48
Filed: 1992-12-22
Abstract: An operating system for scheduling execution of a random set of periodically recurring hard, real-time tasks encountered in multi-media computer system applications and which is useful in a multi-tasking computer operating environment. Periodically recurring computer tasks having relatively short execution periods for which execution results are absolutely required in hard, real-time environments such as multi-media systems, create a significant task scheduling overhead reducing the available processor resource. Overhead processing at task invocation is eliminated in the invention by placing all active recurrent tasks in an execution queue, regardless of the task's current state of activity and by reprioritizing the order of execution of the tasks in the queue whenever a given task execution is completed. Measured by reduction in task scheduling overhead consumed by the processor in scheduling the tasks, this achieves a 50-100% improvement over conventional scheduling and operating systems.

Abstract: The invention relates to a support for tubular particle filters, consisting of two fittings which support the filter at its ends. One of the fittings is resiliently fixed, and the other has a hollow-spherical curvature. The result of this is that, with deviation from the intended perfect arrangement, tightness is always ensured. In addition, the support is operable without problems even with intensive vibrations or wide temperature changes. In an improved embodiment, only the rigidly fixed hollow-spherical fitting has a bore leading to the interior of the filter. In addition, in case of need, electrical contacting is readily possible by suitable selection of the materials. <IMAGE>

Abstract: An apparatus for introducing filler material in a fluid carrier into a measuring chamber (39) in rapid succession is described. The apparatus includes a delivery subsystem (25) for introducing the filler material into the fluid carrier. The delivery subsystem provides the fluid carrier and the filler material to a diverter subsystem (27) which separates the stream into two separate streams. The two separate streams are directed into a rotating concentrator (29) that separates the fluid carrier from the filler material and compresses the filler material. The filler material is further compressed and dewatered in a taper subsystem (33) and drain subsystem (35). The filler material is then dispensed from the drain subsystem into a measuring chamber (39) where it is cut by a knife plate (37) that includes two blades (349, 351) with overlapping cuts. The apparatus is capable of introducing controlled weights or volumes of filler material into a measuring chamber at high speeds.

Abstract: A glow plug for a diesel engine is provided which includes generally a heating coil (1). The heating coil is provided with a first resistance element (11) and a second resistance element (12) connected in series with the first resistance element and having a resistance temperature coefficient positively higher than that of the first resistance element. The second resistance element (12) is made of a Co-Fe alloy whose compositions fall in a range where a change in phase from a body-centered cubic lattice arrangement to a face-centered cubic lattice arrangement does not occur and a change in phase from a close-packed hexagonal lattice arrangement to the face-centered cubic lattice arrangement does not occur even when the second resistance element is subjected to a temperature change from a given room temperature to 1000°C. The first resistance element (11) is welded at its end to an end of the second resistance element (12) to form a connection therebetween which consists of part of material forming the first resistance element and part of the Co-Fe alloy forming the second resistance element (12), the material forming the first resistance element (11) being so selected as to prevent compositions of the Co-Fe alloy in the connection from changing in phase from the body-centered cubic lattice arrangement to the face-centered cubic lattice arrangement and from the close-packed hexagonal lattice arrangement to the face-centered cubic lattice arrangement.

Abstract: A sheet feeder according to the invention comprises a housing (100) provided with a sheet accommodation space in which a plurality of sheets are to be stacked and held; a separation plate (11) which is arranged against the forward edge of the sheets held in the housing and whose surface in contact with the forward edge of the sheets is substantially perpendicular to the sheet face; a feed roller (1), arranged close to the separation plate, for feeding the uppermost one of the sheets held in the housing in the forward direction while in contact with the face of that sheet; and pressurizing means (9,10) for applying pressure to the sheets toward the feed roller. The separation plate has a tapered face (11a) at its forward end inclined in the sheet feeding direction, so that the forward edge of the top sheet in contact with the feed roller run against the tapered face. This arrangement facilitates separation of the top sheet from the next even if the sheets are thicker than usual because the top sheet, as its forward edge runs against the tapered face, slides down in the sheet feeding direction. The close position of the feed roller to the separation plate causes the face of the top sheet, while it is being fed, to be firmly in contact with the tapered face of the separation plate and thereby prevents the forward edge of the next sheet from going over the tapered face.
