Patents by Inventor Brian E. Sueppel

Brian E. Sueppel 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: 6697655
    Abstract: A low power pulse oximeter includes an input stage for amplifying a signal received from a light detector that is switchably connected to the power supply that powers the amplifier. The oximeter also includes an output stage with an LED driver circuit that is switchably connected to the power supply that powers the LED driver circuit. The input and output stages are switchably connected to the power supply when measurements need to be taken. When measurements do not need to be taken, they are switched off to reduce the power consumption of the oximeter.
    Type: Grant

  • Patent number: 5704351
    Abstract: A digital telemetry transmitter for transmitting eight channels of diagnostic quality electrocardiographic data has input circuitry for receiving analog EKG signals originating at electrodes on the patient. The input circuitry includes a circuit for ascertaining the impedance of the electrode connection to the patient and to indicate an electrode fault. EKG signals from the input circuit are provided to a digital/analog converter for converting the analog signals into corresponding digital signals. The analog/digital converter may comprise an eight channel, 20-bit converter, sampling the input signals at a frequency of 10 KHz and providing a digital output signal having a frequency of 500 Hz. The output of the analog/digital converter is provided to a microprocessor control which provides a digital EKG modulating output signal. The output signal is periodically inverted to avoid stationarity in the transmitted data.
