Robert A. Garfield 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).

  • Methods for measuring uterine electrical and mechanical activity
    Patent number: 5522877
    Abstract: The existence of gap junctions between cells is detected by stimulating the cells with electrical pulses having selective parameters and then detecting propagated signals emitted by the cells. A needle is provided having stimulation electrodes thereon from which the stimulating pulses emanate and an array of recording electrodes for detecting the pulses. In an alternative embodiment, an array of piezoelectric electrodes is distributed within the array of recording electrodes. The signals detected by the recording electrodes and piezoelectric electrodes are monitored by a recording device and stored within a computer.
    Type: Grant
    Filed: February 10, 1995
    Date of Patent: June 4, 1996
    Assignee: Schering Aktiengesellschaft
    Inventors: Robert Garfield, Krzysztof Chwalisz, Radoslaw Bukowski
