    摘要: Disclosed is a pressure transducer comprising a pressure sensitive silicon die having a front side exposing piezoresistive means and a back side for receiving pressure from a pressure medium. The transducer further comprises a pressure vessel having an aperture and apparatus including a hermetic seal for mounting the die with the front side of the die facing the aperture. In this manner, the die is compressed toward the pressure vessel when positive pressure is applied to the back side of the die by the pressure medium.

    摘要: A method for providing micro-electromechanical systems (MEMS) devices with multiple motor frequencies and uniform motor-sense frequency separation is described. The devices each include at least one proof mass, each proof mass being connected to a substrate by a system of suspensions. The method includes controlling the resonant frequencies of the MEMS device by adjusting at least two of a mass of the proof masses, a bending stiffness of the proof masses, a length of the suspensions, and a width of the suspensions.

    摘要: For use in a MEMS device having a suspended proof mass, a method and apparatus for securing the MEMS device during a period of high acceleration. The method may include applying a DC voltage between the proof mass and a non-suspended structure of the device. The non-suspended structure may be mounted on a substrate, and the substrate or the non-suspended structure may be electrically isolated from the proof mass by an insulating layer or by one or more islands. Applying the DC voltage creates an electrostatic force that moves the proof mass toward (or holds the proof mass near) the substrate. Movement of the proof mass may be limited by mechanical contact between the proof mass and the insulating layer, the one or more islands, or by a cage mounted on the substrate during the period of high acceleration.

    摘要: An accelerometer switch which has cantilever beams carrying integral end masses formed in a silicon die which is sandwiched between a contact plate and a support plate. Each beam provides switching at a different threshold acceleration level. The fixed contact face of the contact plate is configured with a relief space to permit accelerometer switch operation even though the input acceleration is off-normal and there is twisting of the accelerometer beam.
