Abstract

An angular position/position encoder is provided for determining the position of a moving part through evaluation of the direction-specific changes in the measured values recorded and for serial output in binary form of the position determined in this way, wherein all changes in measured values are also added together, independent of the direction of movement, and then output as the result of the total distance or angle traveled.

Claims

1. An angular position/position encoder for determining the position of a moving part through evaluation of the direction-specific changes (in 2) in the measured values recorded and for serial output in binary form (via 3;

8) of the position determined in this way, wherein all changes in measured values are also added together (in 4), independent of the direction of movement, with the sum total being made available (at 6;

8).

2. The angular position/position encoder according to claim 1, wherein the measuring range refers to a closed angle of 360°

.

3. The angular position/position encoder according to claim 1, wherein the measuring range refers to a partial angle/distance, whereby the finite total angle/distance is made up of more than one of the partial angles/distances that can be recorded.

4. The angular position/position encoder according to claim 1, wherein the sums determined in this way are saved to non-volatile memory (in 4).
