Patents by Inventor John Albert Umina

John Albert Umina 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).

  • Patent number: 8746399
    Abstract: Acoustic waveguides are disclosed for mounting to a conduit. The acoustic waveguides provide a mounting area that minimizes the effect of the mount on the acoustic wave traveling through the waveguide while providing an effective seal, even under high pressure conditions.
    Type: Grant
    Filed: August 19, 2013
    Date of Patent: June 10, 2014
    Assignee: General Electric Company
    Inventors: Xiaolei Shirley Ao, Jin Chang Xu, John Albert Umina

  • Patent number: 7581453
    Abstract: An ultrasonic flow meter system includes transducers arranged with respect to a conduit to define at least one chordal path through fluid flowing in the conduit, and at least one transmitting transducer and receiving transducer pair on the chordal path for generating a transit time signal. At least one receiving transducer is positioned to receive scattered energy to generate a range gated Doppler signal. The system further includes a processing subsystem for exciting the at least one transmitting transducer. The processing subsystem is responsive to the transit time signal and the range gated Doppler signal and configured to generate a velocity profile and a mean velocity of the fluid in the conduit.

  • Patent number: 7523676
    Abstract: A method of determining the flow rate of a fluid in a conduit. Ultrasonic energy is directed through the conduit along multiple paths. The ultrasonic energy is detected and measured using a range gated Doppler technique to determine the velocity of the fluid at several points in the conduit. These point velocities are used to calculate the average flow rate of the fluid in the conduit.
