摘要： A sensor system including a movable member, a sensor, and an interpolator. The sensor is configured to generate a first output signal and a second output signal. The first output signal has a first phase angle, the second output signal has a second phase angle, and a first difference between the first phase angle and the second phase angle has a first value. The first value of the first difference includes an offset related to a mechanical incompatibility between the sensor and the movable member. The interpolator is configured to receive the first output signal and the second output signal. The interpolator is operable to apply a compensation factor to generate a third signal having a third phase. The compensation factor has a value that is based on the mechanical incompatibility between the sensor and the movable member.

摘要： A sensor system including a clock generation module, a sensor, a conditioning module, and an output module. The clock generation module is configured to generate a modulation signal and an output sampling signal. The modulation signal has a modulation frequency, and the sampling signal has a sampling frequency. The sensor is configured to generate an output signal having an output value. The output signal is modulated by the modulation signal, and the output value includes a sensor output value and an offset value. The conditioning module is configured to receive the output signal, condition the output signal, and generate a conditioned output signal including the sensor output value and the offset value. The output module is configured to receive the conditioned output signal and the output sampling signal. The output sampling signal is operable to sample the conditioned output signal at a value that corresponds to the sensor output value.

摘要： A system (50) for determining an absolute position of a device includes a high resolution track (54), a sensor and processing unit (62) associated with the high resolution track, a reference track (58) having a plurality of pole pairs arranged to define a single-track Gray code segment, and an array of Hall effect sensors (66) associated with the reference track to output a reference signal to the sensor and processing unit indicative of the coarse absolute position of the device over the single-track Gray code segment. A third track (70) is provided and at least one sensor (74) is associated with the third track. The sensor and processing unit combines the third track signal, the reference signal, and the position of the device over the high resolution track to determine an initial, fine absolute position of the device.

摘要： A Hall effect sensor system for detecting magnetic fields includes a Hall effect sensor having a central body with a substantially square shape, a first pair of outwardly oriented and opposing arms projecting outwardly from opposing sides of the central body and a second pair of outwardly oriented and opposing arms projecting outwardly transverse from the first pair of arms to form a cross-shape. Each of the arms has a plurality of fingers projecting outwardly therefrom and electrodes are provided on the fingers. In operation, at least two electrodes on the first pair of opposing arms provide a path for bias current through the Hall effect sensor. An electrode on each of the second pair of opposing arms senses voltage formed in the Hall effect sensor by a magnetic field and provides an output to an amplifier.
