Patents by Inventor Wolfgang Briese

Wolfgang Briese has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Piezoelectric resonator with integrated capacitances
    Patent number: 4464599
    Abstract: If a piezoelectric crystal is used in circuits containing ICs with low supply voltage, the additional capacitors required in oscillator or filter circuits cannot be implemented as junction capacitances. To eliminate the need for additional discrete capacitors, these capacitances are implemented with additional films on the crystal.
    Type: Grant
    Filed: September 28, 1981
    Date of Patent: August 7, 1984
    Assignee: International Standard Electric Corporation
    Inventor: Wolfgang Briese
  • Integrated circuit with piezoelectric resonator mounted on blocks comprising capacitors
    Patent number: 4450377
    Abstract: In an assembly of a piezoelectric crystal and an IC on a substrate, additional capacitors, such as load capacitors of a crystal oscillator, are designed as blocks for mounting the crystal on the substrate at its vibration nodes.

  • Four corner piezoelectric crystal support
    Patent number: 4136297
    Abstract: A piezoelectric crystal is held in the slots of two flat spring sheetmetal members with small flaps of the spring being bent out of the slots lying against the bevelled edges of the crystal to improve shock resistance. Additionally the flaps can be fastened to the crystal by using an elastic material.
