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.

摘要： An absolute position encoder converts absolute mechanical position to a digital output value. A single-track, rotary embodiment of the encoder includes several conductive pick-up segments that are symmetrically arranged along a circular pick-up track, with each pick-up segment connected to a respective output terminal. A metallic rotor of the encoder comprises a plurality of contacts that are positioned in alignment with the pick-up track such that the contacts slidably contact different pick-up segments as the rotor is rotated. The contacts on the rotor are conductively interconnected, and are maintained at a common voltage via a sliding connection between the rotor and a collector ring. The output of the encoder is a cyclical Gray code sequence, which may be used in combination with a ROM look-up table accurately track position. Linear and multi-track embodiments are also disclosed.
