Orientable Single-Distance Codes For Absolute Incremental Encoders, Kristian Brian Sims
Theses and Dissertations
Digital encoders are electro-mechanical sensors that measure linear or angular position using special binary patterns. The properties of these patterns influence the traits of the resulting encoders, such as their maximum speed, resolution, tolerance to error, or cost to manufacture. We describe a novel set of patterns that can be used in encoders that are simple and compact, but require some initial movement to register their position. Previous designs for such encoders, called absolute incremental encoders, tend to incorporate separate patterns for the functions of tracking incremental movement and determining the absolute position. The encoders in this work, however, use …
