    Abstract: An encoder system includes a configurable detector array, wherein the configurable detector array includes a plurality of detectors. In an embodiment, the encoder system includes an application-specific integrated circuit (ASIC). The encoder system may also include a memory operable to store a partition map that defines a state for each of the plurality of detectors. In an embodiment, the memory includes a non-volatile memory. The encoder system may also include a controller, such as a microcontroller, operable to read from the memory the partition map and to configure the configurable detector array according to the configuration map. The encoder system may also include an emitter operable to generate a flux modulated by a motion object, wherein the configurable detector array is operable to receive the flux and generate respective current outputs for each of the detectors in response to the flux.

    CPC classification number: G01D5/34715

    Abstract: An encoder system includes a group of programmable detectors, a group of programmable channels, and a programmable connectivity network coupled between the programmable detectors and the programmable channels. Each of the programmable detectors is operable to produce an electric current in response to an optical or magnetic input. Each of the programmable channels is operable to produce an output in response to an electric current input. The outputs from the programmable channels form at least a part of a code word for determining an absolute position of a motion object. The programmable connectivity network is operable to route electric currents from at least a part of the programmable detectors to each of the programmable channels.
