Jack Anthony Martin 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).

  • Tissue Load Sensor with Reduced Calibration Requirements
    Publication number: 20230052280
    Abstract: Measurement of an induced shear wave in tensioned tissue of a given individual is provided to a machine learning system trained to determine absolute load from shear wave signal data. The machine learning system uses a teaching set linking shear wave signal data to absolute load, however, does not require normal calibration data based on measured loads allowing reduced or no calibration for absolute load determinations.

  • Apparatus for dynamic stress measurement
    Patent number: 10631775
    Abstract: Axial stress or similar properties in a stressed tendon or ligament are measured by mechanical excitation of a shear wave in the tendon or ligament measured using ultrasonic displacement techniques at least two different longitudinal positions to derive a shear wave propagation speed. This shear wave propagation speed may be equated to an axial stress on the tissue using a model. Rapidly repeated measurements allow dynamic axial stress measurements to be obtained for clinical study.

  • Apparatus for Intraoperative Ligament Load Measurements
    Publication number: 20190200900
    Abstract: Axial stress or similar properties in a stressed connective tissue may be assessed during surgery by excitation of the ligament to create a shear wave allowing measurement of the shear wave velocity which has been identified as having a component related to axial stress.
