Patent ID: 7650253

Claim:
An accelerometer, comprising: vertical, lateral, and longitudinal acceleration transducers producing uncorrected analog acceleration signals and thermal signals, the uncorrected analog acceleration signals representing vertical, lateral, and longitudinal components of acceleration, and the thermal signals including a signal corresponding to a temperature of the vertical acceleration transducer, a signal corresponding to a temperature of the lateral acceleration transducer, and a signal corresponding to a temperature of the longitudinal acceleration transducer; an error correction system connected to the acceleration transducers for receiving the uncorrected analog acceleration signals and the thermal signals, the error correction system including, (a) a system controller for generating a plurality of correction coefficients based, at least in part, on sampling of each of the thermal signals, (b) an analog to digital converter which converts the uncorrected analog acceleration signals to uncorrected digital acceleration signals, and (c) an error compensation circuit receiving the correction coefficients to compensate the uncorrected digital acceleration signals and produce corrected digital acceleration signals.
