  • Publication number: 20200131032
    Abstract: In some embodiments, a sensor is provided. The sensor includes a microelectromechanical systems (MEMS) substrate disposed over an integrated chip (IC), where the IC defines a lower portion of a first cavity and a lower portion of a second cavity, and where the first cavity has a first operating pressure different than an operating pressure of the second cavity. A cap substrate is disposed over the MEMS substrate, where a first pair of sidewalls of the cap substrate partially define an upper portion of the first cavity, and a second pair of sidewalls of the cap substrate partially define an upper portion of the second cavity. A sensor area comprising a movable portion of the MEMS substrate and a dummy area comprising a fixed portion of the MEMS substrate are both disposed in the first cavity. A pressure enhancement structure is disposed in the dummy area.

  • Patent number: 8319604
    Abstract: An electric release fastening device for a thin-profile space has a fingerprint identifier, a micro drive motor, a change gear set, an electric controller, an electric battery, a moveable fastening cassette, a fastening cassette control unit and a locking locator. When the fingerprint identifier reads the correct identification information, the micro drive motor is ordered by the electric controller to drive the change gear set, and then change the position of the fastening cassette control unit. This switches the positioning or release state between the moveable fastening cassette and the locking locator, and controls or electrically releases the product cover. With this configuration, the electric release fastening device can be assembled into thin-profile spaces with improved applicability.
