  • Patent number: 10342977
    Abstract: Restless Leg Syndrome (RLS) or Periodic Limb Movement Disorder (PLMD) can be treated using high frequency (HF) electrostimulation. This can include selecting or receiving a subject presenting with RLS or PLMD. At least one electrostimulation electrode can be located at a location associated with at least one of, or at least one branch of, a sural nerve, a peroneal nerve, or a femoral nerve. HF electrostimulation can be delivered to the subject, which can include delivering subsensory, subthreshold, AC electrostimulation at a frequency that exceeds 500 Hz and is less than 15,000 Hz to the location to help reduce or alleviate the one or more symptoms associated with RLS or PLMD. A charge-balanced controlled-current HF electrostimulation waveform can be used.

  • Publication number: 20140107457
    Abstract: An electrocardiogram (ECG) sensor system is disclosed that includes one or more interface connectors configured to be coupled to one or more electrodes. The ECG sensor system includes a processor configured to receive an ECG signal via the one or more interface connectors. The processor may be configured to determine one or more noise values associated with the ECG signal. Each of the one or more noise values may be indicative of a measurement of a component of the ECG signal that is potentially related to a non-heart beat source. The processor may be configured to send one or more noise values to an automated troubleshooting system.

  • Publication number: 20130131551
    Abstract: Methods for diagnosing and treating vocal cord dysfunction by recording the position of the vocal cords of a subject during a monitoring period are disclosed. Portable devices are disclosed using electronic signals to provide diagnostic data indicating a subject's closed or open vocal cords to diagnose and treat vocal cord dysfunction. Corresponding software and circuitry are also disclosed.

  • Publication number: 20110282233
    Abstract: A method for detecting an approaching seizure is disclosed. The method includes receiving an analog neurosignal from an electrode, comparing the analog neurosignal with a predetermined amplitude threshold to generate a plurality of digital transitions corresponding to the analog neurosignal transitioning from a first level below the predetermined amplitude threshold to a second level above the predetermined amplitude threshold, generating a plurality of comparator signals, each comparator signal of the plurality of comparator signals corresponding to a comparison of a length of time between a pair of digital transitions of the plurality of digital transitions and a predetermined temporal threshold, and generating a seizure detection signal if at least two of the comparator signals of the plurality of comparator signals are enabled. A seizure detection system for detecting an approaching seizure is also disclosed.
