Abstract

An electronics system has a board with a thermal interface having an exposed surface. A thermoelectric device is placed against the thermal interface to heat the board. Heat transfers through the board from a first region where the thermal interface is located to a second region where an electronics device is mounted. The electronics device has a temperature sensor that detects the temperature of the electronics device. The temperature of the electronics device is used to calibrate an accelerometer and a gyroscope in the electronics device. Calibration data includes a temperature and a corresponding acceleration offset and a corresponding angle offset. A field computer simultaneously senses a temperature, an acceleration and an angle from the temperature sensor, accelerometer and gyroscope and adjusts the measured data with the offset data at the same temperature. The field computer provides corrected data to a controlled system.
