Patents by Inventor Akhelish Kotiya

Akhelish Kotiya 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 inertial actuator
    Patent number: 10750299
    Abstract: Among other things, in general, a piezoelectric actuator for use in a piezoelectric inertial hearing aid is disclosed. The actuator includes at least one bimorph having a top piezoelectric plate, a bottom piezoelectric plate, and a shim with holed ends that extends beyond the length of the plates for securing to bone across, e.g., the mastoid cavity. Actuators having two or morph bimorphs and kits containing the same are also disclosed.
    Type: Grant
    Filed: August 17, 2018
    Date of Patent: August 18, 2020
    Assignee: DAXSONICS ULTRASOUND INC.
    Inventors: Akhelish Kotiya, Robert B. A. Adamson, Manohar Bance, Jeremy A. Brown

  • Subcutaneous piezoelectric bone conduction hearing aid actuator and system
    Patent number: 8942400
    Abstract: An implantable bone-conduction hearing actuator based on a piezoelectric element, such as a unimorph or bimorph cantilever bender, is described. Unlike other implantable bone conduction hearing actuators, the device is subcutaneous and once implanted is entirely invisible. The device excites bending in bone through a local bending moment rather than the application of a point force as with conventional bone-anchored hearing aids.
