摘要： An electronic absolute position encoder is provided including a scale, a detector portion and a signal processing configuration. The scale includes a first scale pattern of signal modulating elements, wherein the first scale pattern includes a spatial characteristic of the signal modulating elements which progressively changes as a function of position along a measuring axis direction and defines an absolute measuring range. The spatial characteristic includes at least one of a spatial wavelength or a spatial frequency of the signal modulating elements and is unique at each unique position in the absolute measuring range. The detector portion includes a group of sensing elements, and the signal processing configuration determines an absolute position of the sensing elements relative to the scale within the absolute measuring range. In various implementations, the signal processing configuration may utilize Fourier transform processing and/or other processing for determining the absolute position.

摘要： At a time that a position detecting device is initiated, an arithmetic processing unit calculates the absolute position of a rotating shaft at the time of initiation, on the basis of first to third analog signals corresponding to first to third angles of rotation, which are detected respectively by first to third rotational angle detectors. During rotation of the rotating shaft, a current position counter detects a current absolute position of the rotating shaft by counting a number of pulses of forward rotation pulses or reverse rotation pulses, corresponding to the first angle of rotation detected by the first rotational angle detector, taking as a standard a total number of pulses corresponding to the absolute position of the rotating shaft at the time of initiation.

摘要： A rotary element is equipped with a pattern representing a reflected binary code on at least three bits. A detection circuit is configured to sense the pattern and deliver an incident signal encoded in reflected binary code on at least three bits. The incident signal is converted by a transcoding circuit into an intermediate signal encoded in reflected binary code on two bits. A decoding stage decodes the intermediate signal and outputs at least one clock signal representing the amount of rotation of the rotary element and a direction signal representing the direction of rotation. A processing circuit determines the movement of the rotary element, and has at least one general purpose timer designed to receive the at least one clock signal and direction signal.

摘要： Some embodiments of the invention relate to an absolute code scale of an angle or linear position encoder, which is composed of a first absolute code sequence having a first primary code period length, which is periodically continued, and at least one second absolute code sequence having a second primary code period length, which is periodically continued. The first and the at least one second absolute code sequence are codeword-foreign in relation to one another in this case.Along the absolute code scale, in each case one section from the first and one section from the at least one second absolute code sequence are successively arranged alternately and in this case the absolute code sequences are each shifted in relation to one another in the different sections from the same absolute code sequence along this arrangement.
