Robert Bruce Alexander Adamson 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).

  • High-frequency ultrasound imaging system
    Patent number: 10181317
    Abstract: A high frequency ultrasound analog beamformer comprises a linear array of surface acoustic wave (SAW) devices formed on a single crystal piezoelectric substrate, such as a PMN-PT single crystal piezoelectric substrate. Each SAW device comprises ultrasound input and output electrode structures separated by a variable delay structure. The beamformer further comprises a delay controller operably connected to each variable delay structure to control the delay of each SAW device to dynamically focus signals received at each input electrode.
    Type: Grant
    Filed: February 26, 2010
    Date of Patent: January 15, 2019
    Assignee: DALHOUSIE UNIVERSITY
    Inventors: Jeremy Brown, Robert Bruce Alexander Adamson
  • Subcutaneous piezoelectric bone conduction hearing aid actuator and system
    Patent number: 8965021
    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.
