Patents by Inventor June Shen-Epstein

June Shen-Epstein 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).

  • Tri-axis accelerometer
    Patent number: 7430909
    Abstract: In an embodiment of the present invention there is provided a micro-electromechanical (MEMS) accelerometer, including a substrate, a first sensor and a second sensor. The first sensor is configured to measure an acceleration along a first axis parallel to a plane of the substrate. The second sensor is configured to measure an acceleration along an axis perpendicular to the plane of the substrate. The second sensor comprises a first beam, a second beam and a single support structure. The single support structure supports the first and second beams relative to the substrate, wherein the first and second beams circumscribe the first sensor.
    Type: Grant

  • Z-axis angular rate sensor
    Publication number: 20050072231
    Abstract: An oscillatory rate sensor is described for sensing rotation about the “z-axis”. It is tuning-fork in nature with structural linkages and dynamics such that fundamental anti-phase oscillation of two proof masses is accomplished by virtue of the mechanical linkages.

  • Z-axis angular rate micro electro-mechanical systems (MEMS) sensor
    Publication number: 20050066728
    Abstract: An oscillatory angular rate MEMS sensor is described for sensing rotation about the “Z-axis”. Embodiments are either coupled-mass tuning-fork or single oscillating-mass in nature. The sensor includes mechanical and electrical function integration, and is preferably manufactured by a unique MEMS fabrication process.
