  • Patent number: 9566015
    Abstract: A signal processing module includes an input module electronically coupled to a sensing probe of a nerve integrity monitoring system. The probe senses electrical signals from a patient during operation of an electrosurgical unit. The input module receives an input signal from the probe. An EMG detection module is coupled to the input module and is adapted to detect conditions in the input signal. The conditions are classified as a function of a level of electromyographic activity. An output module, coupled to the EMG detection module, provides an indication of electromyographic activity in the input signal based on the detected conditions.

  • Patent number: 9423049
    Abstract: A reading and adjustment tool for use with a valve having a pressure or flow setting adjustable to a plurality of pressure or flow settings is disclosed. The tool includes a signal generator and an excitation coil coupled to the signal generator. The signal generator includes an adjustment interface configured to generate an adjustment signal to adjust the pressure or flow setting and a reading interface to generate a reading signal to read the pressure or flow setting of the valve. At least one excitation coil is connected to the signal generator and configured to generate an oscillating electromagnetic field based on one of the adjustment signal and reading signal.

  • Publication number: 20110196349
    Abstract: A handpiece and system having a surgical handpiece adapted to perform an operation on a patient, the surgical handpiece having a primary circuit being driven by an applied signal. A controller is operatively coupled to supply operating power to the surgical handpiece. A hand switch is operatively coupled in conjunction with the surgical handpiece to at least partially control an operation of the surgical handpiece. The switch has a secondary resonant circuit receiving the applied signal from the primary circuit and couples a response signal back to the primary circuit. Detection circuitry, operatively coupled to primary circuit, is responsive to a characteristic parameter of the response signal indicative of the presence of the hand switch in proximity of the surgical handpiece.
