Abstract: An encoder system includes a configurable detector array, wherein the configurable detector array includes a plurality of detectors. 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. 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. In an embodiment, the current outputs from detectors having a same state are grouped together. The encoder system may also include one or more current duplicators to duplicate the current outputs from detectors having one state to group with the current outputs from detectors having a different state. The encoder system may also adjust weights of the current outputs.

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.

Abstract: A device includes an optical modulator configured to produce first and second modulated optical signals in response to a first electrical signal and a reference optical signal. The device further includes a phase detector configured to receive first and second encoded optical signals and the first and second modulated optical signals and to produce a second electrical signal indicating a phase difference between the first encoded optical signals and the first modulated optical signals. The device further includes a voltage-controlled oscillator configured to produce electrical pulses in response to the second electrical signal, and a counter configured to count a number of the electrical pulses, producing a count. The first electrical signal to the optical modulator is the count or a derivative of the count.

Abstract: An optical detection system includes a first device that has a first light source and a first light detector, and a second device that has a second light source and a second light detector. The first and second devices are configured to turn on and off the first and second light sources periodically based on first and second control signals, respectively. The first and second light sources are configured not to emit light simultaneously. The first and second light sources emit light in wavelength ranges that overlap. The optical detection system further has the characteristic that when the first light source is turned on, a radiant power delivered to the second light detector from the first light source is at least 25 percent of a radiant power delivered to the first light detector from the first light source.
