Title: Quality factor correction of micro electro-mechanical system (mems) gyroscope
Inventor: LYNN JAMES
IPC: G01C19/5726
Filed: 2019-01-11
Abstract: To provide a circuit and a method for correcting a micro electro-mechanical system (MEMS) gyroscope, with respect to a change in a quality factor.SOLUTION: A change in a quality factor occurs, for example, when mechanical loss is introduced into a resonator of a gyroscope, that is caused by thermoelastic attenuation or squeeze film attenuation and that may obstruct a function of a gyroscope for accurately detecting angular speed. Quality factor correction can be performed by generating a correction signal including a time attenuation factor which is dependent on a quality factor of the resonator. In this way, an artifact which may arise in output of the gyroscope, when correction is not performed, is limited. In addition, or alternatively, the quality factor correction can be performed by controlling force driving the resonator of the gyroscope. This can be carried out by, for example, controlling an average value of a driving signal.SELECTED DRAWING: Figure 3B

IPC: G05D1/02
Filed: 2019-02-20
Abstract: To provide a mobile body control device capable of easily changing a speed pattern.SOLUTION: A track generation device generates a target track for a moving body to move from a start point position to a target position. The track generation device sets a speed pattern for moving on the target track. The speed pattern indicates the change in speed over a movement period. When the speed pattern is integrated over time, the path length of the target track is obtained. The track generation device generates a virtual time corresponding to the actual time used in the speed pattern. The virtual time is a time at which the elapsing speed of the virtual time with respect to the actual time can be reduced, in at least a part of a change period of the movement period of the speed pattern. The track generation device changes the speed pattern during the change period based on the virtual time. The track generation device reduces the speed during the change period and extends the speed pattern during the change period in a time axis direction. Time integration values become equal to each other between the speed patterns before and after the change.SELECTED DRAWING: Figure 1
