William D. Beaver 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).

  • Surface mount quartz crystal resonators and methods for making same
    Publication number: 20030193271
    Abstract: A surface mount quartz crystal resonator includes a quartz crystal-based plate including a central portion adapted to resonate at a desired frequency, and a border substantially surrounding a peripheral region of the central portion. The border includes a first region physically separated from the central portion, and a second region joined to the central portion. A base plate is provided which is secured to the plate so that the central portion of the plate is free to resonate relative to the base plate. A cover plate is provided and is secured to the plate so that the plate is located between the base plate and the cover plate. At least one, and preferably both, of the base plate and the cover plate are made of quartz.
