Patents by Inventor James M. Hossack

James M. Hossack 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).

  • Ultrasonic method
    Patent number: 4888086
    Abstract: Ultrasonic apparatus for use in detecting an object having a transducer. The transducer has an array of at least one element coupled directly into air. The apparatus also includes a transmitter which may be multi-channel, a receiver which may be multi-channel, a transmit receive switch, and a computer for causing operation of said transmit receive switch to cause sequential supplying of pulses of energy from the transmitter to the element or elements of the transducer and for receiving energy received by the transducer. The element or elements of the transducer are provided with a roughened surface to produce high frequency ultrasonic energy.
    Type: Grant
    Filed: June 9, 1988
    Date of Patent: December 19, 1989
    Assignee: Ultrasonic Arrays, Inc.
    Inventors: James M. Hossack, Jeffrey E. Powers, John K. Billings

  • Dual reference surface transducer
    Patent number: 4769793
    Abstract: An ultrasonic transducer and method for detecting the distance to an object using ultrasonic energy. The transducer includes a foil which creates ultrasonic energy. First and second reference surfaces are provided which are spaced between the transducer and the object. The two reference surfaces provide for immunity against temperature and positional changes.

  • Ultrasonic transducer component and process for making the same and assembly
    Patent number: 4695986
    Abstract: Ultrasonic transducer assembly having a piston with a substantially planar surface formed of a conducting material. An insulating foil element having first and second surfaces overlying the substantially planar surface of the piston. The foil has a conducting layer carried by the first surface. A plurality of spaced apart support elements are disposed between the substantially planar surface of the piston and the second surface of the foil.
