Abstract:
A system including an encoder, multiple sensing elements and control logic. The encoder has a pole pitch and is configured to rotate in a direction of rotation.

Abstract:
An apparatus for determining a state parameter of an object to be monitored includes a means for providing a plurality of measurement values, wherein the measurement values include information relating to the state parameter of the object to be monitored, a comparison means for comparing the measurement value to a predeterminable comparison parameter, wherein the comparison means is formed to output a first comparison signal when a predeterminable number of measurement values falls below the comparison parameter within a measurement interval, or to output a second comparison signal when the predeterminable number of measurement values exceeds or reaches the comparison parameter, wherein the first comparison signal or the second comparison signal indicate the state parameter.
Abstract:
A sensing system and method. A coded wheel is configured to generate a signal that varies with rotation of the coded wheel. A sensor is configured to sense the varying signal and output a corresponding signal. A correction module is configured to receive the signal output by the sensor and compare the received signal to a stored signal and detect a defect in the coded wheel in response to the comparison.
