摘要： An absolute encoder has a code plate formed with an absolute pattern and an incremental pattern. A first detector detects the absolute pattern, and outputs an absolute signal. A second detector detects the incremental pattern, and outputs an incremental signal. The absolute encoder stores the absolute signal according to an external input signal, and forms a corrected absolute signal on the basis of the incremental signal input after the absolute signal is stored.

摘要： A position measuring device that includes a scanning device and a measurement representation that is scanned by the scanning device. The measurement representation includes a code of a succession of code elements, which form at least a first codeword and a second codeword that define an absolute position, the first codeword and the second codeword are arranged interlaced with each other in that code elements associated with the second codeword are inserted into a succession of code elements associated with the first codeword. The code elements associated with the first codeword have inverse properties with respect to the code elements associated with the second code codeword.

摘要： A movable barrier operator includes an absolute position detector which provides a unique value for each position of the barrier along its path of travel. The absolute position detector employs multiple binary serial streams and one multiple clock stream. After the first five cycles of the clock stream, the binary streams can be decoded by a processor to produce an absolute position. Every clock edge produces a new absolute position along the path of travel.
