Patent number: 10295559Abstract: To calibrate an accelerometer, a rotating member is rotated over multiple periods, thereby causing the accelerometer attached to the rotating member to repeatedly turn over. A processor obtains acceleration measurements as the accelerometer turns and determines a set of local minima and maxima of the acceleration measurements. Based on these local minima and maxima, the processor determines a sensitivity of the accelerometer. The processor stores the sensitivity for use in adjusting subsequent accelerometer measurements, thus calibrating the accelerometer.Type: GrantFiled: September 30, 2014Date of Patent: May 21, 2019Assignee: NXP USA, Inc.Inventors: Chad S.
