摘要:
Interfacing application programs and motion sensors of a device. In one aspect, a high-level command is received from an application program running on a motion sensing device, where the application program implements one of multiple different types of applications available for use on the device. The high-level command requests high-level information derived from the output of motion sensors of the device that include rotational motion sensors and linear motion sensors. The command is translated to cause low-level processing of motion sensor data output by the motion sensors, the low-level processing following requirements of the type of application and determining the high-level information in response to the command. The application program is ignorant of the low-level processing, and the high-level information is provided to the application program.

The module further includes an application specific integrated circuit (ASIC) to receive both the first measurement output from the linear accelerometer and the second measurement output from the first rotation sensor. The ASIC includes an analog-to-digital converter and is implemented on a second substrate. The first substrate is vertically bonded to the second substrate.

摘要:
An angular velocity sensor has two masses which are laterally disposed in an X-Y plane and indirectly connected to a frame. The two masses are linked together by a linkage such that they necessarily move in opposite directions along Z. Angular velocity of the sensor about the Y axis can be sensed by driving the two masses into Z-directed antiphase oscillation and measuring the angular oscillation amplitude thereby imparted to the frame. In a preferred embodiment, the angular velocity sensor is fabricated from a bulk MEMS gyroscope wafer, a cap wafer and a reference wafer. In a further preferred embodiment, this assembly of wafers provides a hermetic barrier between the masses and an ambient environment.
