1. An absolute position magnetic encoder comprising:
- a first magnetic track configured for a binary output;
a second magnetic track configured for a decimal output;
a first magnetic sensor positioned proximate the first magnetic track to detect the magnetic field of the first magnetic track; and
a second magnetic sensor positioned proximate the second magnetic track to detect the magnetic field of the second magnetic track;
wherein the encoder is selectively operable to provide one of the binary output and the decimal output.

Abstract
An absolute position magnetic encoder includes a first magnetic track configured for a binary output, a second magnetic track configured for a decimal output, a first magnetic sensor positioned proximate the first magnetic track to detect the magnetic field of the first magnetic track, and a second magnetic sensor positioned proximate the second magnetic track to detect the magnetic field of the second magnetic track. The encoder is selectively operable to provide one of the binary output and the decimal output.

11. A method of calculating an absolute position of an encoder, the method comprising:
-
providing a first magnetic track configured for a binary output; providing a second magnetic track configured for a decimal output; detecting a first count value from the first magnetic track; detecting a second count value from the second magnetic track substantially simultaneously with the first count value; and calculating a third count value indicative of the absolute position of the encoder using the first and second count values, the third count value conducive to provide one of the binary output and the decimal output. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
