  • Patent number: 10338115
    Abstract: A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.

  • Patent number: 9861425
    Abstract: A return electrode monitoring (REM) system for an electrosurgical system is disclosed. The REM system includes circuit components or circuitry for monitoring the magnitude of an interrogation or drive signal, and one or more electrode pads including one or more pairs of split electrode pads. The REM system, while sweeping an interrogation signal over or across a frequency range, monitors the magnitude of the interrogation signal. The REM system determines if there is a frequency shift in the interrogation signal. If there is a frequency shift, the REM system determines the frequency shift and uses it to calculate a reactance value of the impedance. The complex impedance can then be determined. The complex impedance, or at least the reactance value, can be used to determine the capacitive coupling between the patient and pad interface.
