  • Patent number: 11363987
    Abstract: The method and apparatus disclosed herein determine a user cadence from the output of an inertial sensor mounted to or proximate the user's body. In general, the disclosed cadence measurement system determines the user cadence based on frequency measurements acquired from an inertial signal output by the inertial sensor. More particularly, a cadence measurement system determines a user cadence from an inertial signal generated by an inertial sensor, where the inertial signal comprises one or more frequency components. The cadence measurement system determines a peak frequency of the inertial signal, where the peak frequency corresponds to the frequency component of the inertial signal having the largest amplitude. After applying the peak frequency to one or more frequency threshold comparisons, the cadence measurement system determines the user cadence based on the peak frequency and the frequency threshold comparison(s).

  • Patent number: 11317841
    Abstract: An electrode management solution for neuromonitoring applications such as electroencephalography (EEG) procedures provides for the verification of the locations and connections of electrodes. The brain is modeled as a volume conductor and an expected attenuated signal generated by an electrical signal present in the form of an electrical dipole at any other point in the brain is calculated. A known signal is connected between electrodes at ‘presumed’ locations. This action generates a defined electrical field which can be measured between any of the other electrode locations. The amplitude and phase of the measured signals are a function of the input signal, the volume conductor, and the geometric relations of the two electrodes. By comparing the expected values with the measured values, the relation between the electrodes is verified.
