摘要： A digital signal processing circuit of a so-called RNS system in which a residue number system ("RNS") encoder for converting input data into RNS code data is provided with a converter for connecting the input data into a multiple of one or more of the moduli of the RNS code. The converter is operated in the case of occurrence of trouble in the processing system of the modulus to locate the site of the trouble on the basis of the output of the digital signal processing circuit.

摘要： In an apparatus for detecting movement of a television image in response to frame difference data corresponding to a difference between present frame data and previous frame data, a video signal is divided into a plurality of segmental areas for each frame, a pixel or picture element is selected to represent each of the segmental areas, frame difference data are produced for each of the segmental areas by calculating differences in the position or coordinates of a pixel representative of a segmental area of a previous frame from the respective picture element of the corresponding segmental area in the present frame, and each of the calculated differences smaller than a predetermined magnitude, and which would be characteristic of a stationary background portion of the television image, is omitted from the frame difference data. This is effective to improve the movement vector detection accuracy. The apparatus has a circuit for zeroing the frame difference data, and thereby improving, the movement vector detection reliability when the number of the calculated differences omitted from the frame difference data exceeds a predetermined value.

摘要： In the structure for reinforcing a concrete member and the reinforcing method of the present invention, a reinforcing sheet is arranged and joined to a various kinds of concrete member, such as column, beam, wall, floor, and the like, by applying the reinforcing sheet to the surface of the concrete member and attaching to the fixing anchors joined to the concrete member or the other concrete member surrounding the concrete member. The fixing anchor comprises a large amount of reinforcing fiber, and is obtained by bundling a part of the reinforcing fiber. The unbundled portion of the fixing anchor is spread along the surface of the concrete member. The reinforcing sheet is over-lapped to the unbundled portion using resin adhesives. In addition, reinforcing fibers, such as carbon fiber, aramid fiber, glass fiber, and the like are preferably used as the material comprising the fixing anchor and reinforcing sheet. Thereby, the reinforcing member can be joined via the fixing anchor to the concrete members. Therefore, it is possible to securely join the edges of the reinforcing member, and reliably exert the reinforcing effects on the concrete member.

摘要： A digital video signal processing device is capable of avoid phase difference of video signals in case of converting the rate of digital video signals. In case of converting the first digital video signal to the second digital video signal, the sync points of the first digital video signal and the second digital video signal can be coincided by coinciding the predetermined numbered clock timings of the first and second clocks with a clock synchronizing device. Since the rate is converted in utilizing a filter having a characteristic to coincide sync points of the first and second digital video signals, sync points of the first digital video signal and the second digital video signal can be coincided, so that the phase difference of video signals can be avoided in advance in either case.

摘要： A sampling rate converting apparatus is arranged in such a manner that, in a case where the frequency ratio of a first or a second sampling frequency holds a simple integral relationship, its oversampling filters are composed of FIR type digital filters the length of each of which corresponds to the least common multiple of the frequency ratio so that the first or the second sampling frequency of the digital signal is converted into the second or the first sampling frequency.A sampling rate converting apparatus is arranged in such a manner that coefficients to be given to weighting means of oversampling filters are changed by selecting coefficient data of coefficient generating means including a plurality of selectable coefficient data so that, in a case where the frequency ratio of the first or the second sampling frequency does not hold a simple integral relationship, the first or the second sampling frequency of the digital signal can be converted into the second or the first sampling frequency.

摘要： A circuit for detecting motion of a color video signal includes serially-connected first and second frame memories for storing the video signal frame-by-frame. First and second difference video signals are produced which respectively correspond to the difference between the input and output signals of the first frame memory and the difference between the input and output signals of the second frame memory, whereupon first and second absolute values are generated in response to the first and second difference video signals, respectively. Such first and second absolute values are employed for detecting first and second correlation patterns of the first and second difference video signals, respectively, and then motion of the video signal is discriminated on the basis of the detected correlation patterns.

摘要： An input receives a digital video signal that when free of error lies within a given frequency band and when not free of error contains components lying outside the frequency band. Such components have an amplitude versus frequency distribution that is a function of the number and location of errors in the digital video signal. A detector is responsive to the input for detecting components of the digital video signal lying outside the frequency band, and a pattern recognition circuit responsive to the detector produces an output indicative of the number and location of the errors.
