Patents by Inventor Henry Stanislaw

Henry Stanislaw 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).

  • Simultaneous radio frequency and magnetic field microprocessor reset circuit
    Patent number: 5186170
    Abstract: An implant for stimulating the vagus nerve receives commands over a radio frequency link. The implant disables a voltage convertor used in providing the stimulation signal at periodic intervals to monitor for communications attempts. The implant provides radio frequency marker pulses before providing stimulation signals of certain frequencies. During the providing of stimulation signals the implant monitors the voltage overhead present between the voltage source and the load and adjusts the overhead to a desired level. The implant changes the voltage applied to certain internal components during stimulation periods to allow full power operation during those intervals and reduced power levels at other intervals. The implant is reset by the placing a magnet in a given location in conjunction with the application of a radio frequency transmission for a given period.

  • Constant current sources with programmable voltage source
    Patent number: 5154172
    Abstract: An implant for stimulating the vagus nerve receives commands over a radio frequency link. The communication protocol uses asynchronous communications devices with parity checking and echoing of communicated characters and passwords to improve communication error checking. The implant disables a voltage convertor used in providing the stimulation signal at periodic intervals to monitor for communications attempts. The implant provides radio frequency marker pulses before providing stimulation signals of certain frequencies. During the providing of stimulation signals the implant monitors the voltage overhead present between the voltage source and the load and adjusts the overhead to a desired level. The implant changes the voltage applied to certain internal components during stimulation periods to allow full power operation during those intervals and reduced power levels at other intervals.
