Abstract: A method and system for providing gyroscope bias self-calibration are described herein. The method comprises powering on one or more gyroscopes; after a predetermined first period of time, and upon determining that the one or more gyroscopes is stationary, measuring input rates of rotation during a predetermined second period of time; and determining an average rate of rotation for each gyroscope channel based upon the measured input rates of rotation during the predetermined second period of time. After determining the average rate of rotation and after the predetermined second period of time, the method further comprises commencing additional measurements by the one or more gyroscopes; determining calibrated gyroscope measurements by subtracting the average rate of rotation from each of the additional measurements; and providing, at the output of the one or more gyroscopes, the calibrated gyroscope measurements.

Abstract: A method for generating a sensor output from the outputs of first and second sensors is provided. The method comprising receiving the outputs from the first and second sensors; estimating an offset between the outputs of the first and second sensors over a first range of outputs; adjusting the output of the second sensor based on the estimated offset; and generating a sensor output, based on the output of the first sensor, the adjusted output of the second sensor and a blending function that blends the output of the first sensor and the adjusted output of the second sensor.

Abstract: There is set forth herein an imaging terminal having a picture taking mode of operation. In the picture taking mode of operation the terminal can capture a frame of image data into a buffer memory prior to activation of a trigger signal. The terminal can be operative so that responsively to activation of a trigger signal, the terminal transmits one or more frames of the buffer memory to a storage memory. The terminal can further be operative so that responsively to activation of a trigger signal an operator is presented with indicators of frames captured both prior to and subsequent to the activation of the trigger signal. The terminal can be operative so that an operator can select for archiving one or more frame.
