Real rotary position encoders use Gray code to prevent slight misalignments and border cases from being a problem. For some people, the term Gray code (named after [Frank Gray], the inventor ...

Engineers use rotary encoders to measure the angular position of an attached device, such as a motor shaft, or to measure distance indirectly when used with a linear belt drive, for example. Rotary ...

Take three filaments with the air-gap-pipe sensors spaced to form a Gray code, and he could digitally read the location. He appears to be developing this discovery into a product. We’re not ...

Tracks on absolute encoders often are arranged to produce a binary output called Gray code. The advantage of Gray code over straight binary is that only one bit changes at a time. Thus ...

Arduino library for reading rotary encoders that output a 2-bit gray code. Rotary r = Rotary(2, 3); void setup() { r.begin(); } void loop() { result = r.process(); if ...

Abstract: A slight increase in the physical dimensions of the single-track gray code (STGC) encoders in exchange for using fewer reading heads (fewer bits) is the subject that is addressed in this ...

This is because Gray codes are named after Frank Gray, who patented their use for shaft encoders in 1953. You can find a really Interesting Paper on this at www.faqs.org. I love this sort of stuff, ...
