Micro inertial measurement system
First Claim
1. An inertial measurement device, the device comprising:
- a sensing module comprising a support and a flexible circuit board,wherein the support comprises six external surfaces, at least one external surface comprising a groove engraved thereon, andwherein the flexible circuit board (1) comprises one or more electrical components, the one or more electrical components comprising at least one of a gyroscope or an accelerometer, (2) is coupled to the support with the at least one of the gyroscope or the accelerometer embedded within the groove on the at least one external surface of the support, and (3) comprises a front surface configured to support the one or more electrical components and a back surface opposite the front surface and not supporting any electrical components, wherein a portion of the flexible circuit board is disposed over a corresponding portion of the at least one external surface outside of the groove engraved thereon, the front surface of the flexible circuit board facing the at least one external surface and the back surface facing away from the at least one external surface.

Abstract
A micro inertial measurement system includes a housing, a sensing module, and a damper. The sensing module includes a rigid sensing support, a measuring and controlling circuit board mounted on the rigid sensing support and an inertial sensor set on the measuring and controlling circuit board. The inertial sensor includes a gyroscope and an accelerometer. The sensing module is mounted in the housing. The damper is mounted in the housing and set in the gap between the sensing module and the inside wall of the housing. By use of the above-mentioned structure, the noise immunity of the inertial measuring system can be greatly improved, and the volume and weight of the inertial measuring system can be greatly reduced.
