摘要： A clock output unit outputs a synchronous clock signal. A serial data receiving unit receives data representing an absolute position and an encoder sends data in synchronization with the synchronous clock signal. A position conversion unit converts the received absolute position into a current position. The position conversion unit calculates a difference between a last received absolute position and an absolute position received immediately before the last received absolute position. The position conversion unit obtains the latest current position by adding the difference and a current position that was calculated immediately before the latest current position. If the absolute value of the calculated difference is greater than a threshold value, the position conversion unit determines that the last received absolute position has an error.

摘要： An absolute encoder is provided with a movable member, which may be a disc, a photodetector and a processing circuit. The movable member has a plurality of tracks T arranged from higher to lower orders, each track having a bright and dark pattern. The photodetectors A1-A4 receive a light through the bright and dark patterns to output triangular detection signals A1-A4 associated with the track T. The processing circuit processes the detection signals A1-A4 to produce bit signals P1-P3 which indicate a position of the movable member. The processing circuit is provided with an input unit 1, a comparator unit 2 and a logic unit 3. The input unit 1 receives the detection signals A1-A4 for producing a plurality of triangular wave signals having the same period but different phases. The comparator unit 2 comparatively processes the triangular wave signals with each other to produce a plurality of rectangular wave signals having different phases. The logic unit 3 logically processes the rectangular wave signals with each other to output at least three bit signals P1-P3 from one track.

摘要： A pulse encoder (2) is provided for generating a position code IP corresponding to the rotational position of a rotor of a motor (1), as well as rotation pulses AP, BP each of which is produced whenever the rotor rotates by a predetermined amount. The rotation pulses AP, BP are applied to a counter (32) via quadrupling pulse generating circuit (30). A leading edge/trailing edge sensing circuit (31) is provided for sensing a transition point of the position code, with the counter (32) being preset by an output from the circuit (32). Thus, the position of the rotor is capable of being indicated precisely based on the position code and the value counted by the counter.

摘要： 933,013. Electric selective signalling systems. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Feb. 24, 1960 [March 6, 1959], No. 6449/60. Class 40 (1). In a device for converting a physical displacement into corresponding electric signals the tracks of a coded scale are scanned transversely and a pulse is produced each time a " mark " is passed. As described, resiliently mounted photo-electric cells are oscillated across the tracks of a coded scale. The coded scale, Fig. 8, comprises three concentric groups 6, 7, 8, each of nine tracks. The first group of tracks 6 (the hundreds) are marked, as shown, so that each of the ten segments into which the disc is divided contain a different number of marks and thus radial scanning of this group of tracks will produce a group of pulses corresponding in number to the particular sector scanned. The second 7 and third 8 groups of tracks are similarly marked to give units and tens respectively. Each group of tracks is scanned by a single photo-electric cell 20, Fig. 2, the three cells being mounted side-by-side on a resiliently mounted member 18. This member 18 is caused to oscillate by a coil 21 carrying 50 c/s. mains current and a permanent magnet 22, and is so constrained by stops that each cell only scans its associated group of tracks. Two methods of preventing ambiguity errors are described. In the first the scale is resiliently coupled to the shaft and is caused to progress step-by-step by teeth on its rim which cooperate magnetically with a fixed toothed permanent magnet and in the second an additional track on the scale is used to control the position of a scanning slot.

摘要： An encoder system includes a configurable detector array, wherein the configurable detector array includes a plurality of detectors. The encoder system may also include a memory operable to store a partition map that defines a state for each of the plurality of detectors. The encoder system may also include an emitter operable to generate a flux modulated by a motion object, wherein the configurable detector array is operable to receive the flux and generate respective current outputs for each of the detectors in response to the flux. In an embodiment, the current outputs from detectors having a same state are grouped together. The encoder system may also include one or more current duplicators to duplicate the current outputs from detectors having one state to group with the current outputs from detectors having a different state. The encoder system may also adjust weights of the current outputs.

摘要： Methods and apparatuses for transmitting coding indication information and determining a precoding matrix, for use in resolving the problem that the resolution of code words in a codebook generated by using a combination of a beam vector subgroup and column selection cannot be flexibly adjusted. The method comprises: determining first precoding indication information and second precoding indication information, the first precoding indication information corresponding to a first-stage precoding matrix, the second precoding indication information corresponding to a direction weighting vector and a phase adjustment factor, the direction weighting vector being used for performing interpolation processing on parts representing angles corresponding to beam vectors in the all beam vectors in each polarization direction in the first-stage precoding matrix, the phase adjusting factor being used for performing phase adjustment on different polarization directions of the first-stage precoding matrix, and the first-stage precoding matrix, the direction weighting vector, and the phase adjustment factor being used for generating a precoding matrix. The resolution of a precoding matrix is flexibly adjusted by using a direction weighting vector.
