  • Hybrid accelerometer assembly
    Patent number: 5233871
    Abstract: A microaccelerometer package is provided for use in on-board automotive safety control and navigational systems. The microaccelerometer package is constructed so as to minimize the influence of extraneous mechanical stress and vibrational resonance on the micromachined accelerometer. The microaccelerometer package includes a rigid housing in which there is a cavity for receiving the micromachined accelerometer unit and the signal-processing circuitry. The lower surface of the cavity is interrupted by a recess projecting below the plane of the lower surface. The micromachined accelerometer unit is secured within the recess so as to be below the plane of the lower surface. The signal-processing circuitry is supported by a substrate which is secured to the lower surface of the cavity.
