Abstract: The invention comprises a system that monitors heart activity through embedded ECG sensors in a desk, and desk-related amenities such as a chair, a computer keyboard, a mouse, and a floor mat. The invention also comprises pressure sensors for monitoring a user's presence at the desk. Signals measured from the ECG or pressure sensors are transmitted (in a wired, or wireless fashion) to a computer processing device which applies algorithms to refine the collected signals, and passively estimate the user's ECG.

Abstract: A system and method is operable to automatically determine the amplitude and latency of one or more evoked potential (EP) or event-related potential (ERP) from electroencephalography (EEG) data. The EEG data from an EEG scan is separated into one or more epochs containing the desired EP or ERP waveforms. Epochs corresponding to the same type of EP or ERP such as N100, P300, and N400 are averaged automatically. The averaged epochs are automatically filtered in the time-frequency domain using an automatically selected filtering mask associated with the type of EP or ERP. A corresponding peak is automatically identified from the filtered epoch, in which the amplitude and latency is automatically measured.

Abstract: Devices, systems, and methods herein relate to electromyography (EMG) that may be used in diagnostic and/or therapeutic applications, including but not limited to electrophysiological study of muscles in the body relating to neuromuscular function and/or disorders. Sensor assemblies and methods are described herein for non-invasively generating an EMG signal corresponding to muscle tissue where the sensor may be positioned directly on a surface of the muscle tissue including any associated membrane (e.g., mucosal, endothelial, synovial) overlying the muscle tissue. A sensor assembly may include one or more pairs of closely spaced, atraumatic electrodes in a bipolar or multipolar configuration. The first and second electrodes may be applied against a surface of muscle tissue (that may include a membrane overlying the muscle) and receive electrical activity signal data corresponding to an electrical potential difference of the portion of muscle between the electrodes.

Abstract: A device for functional electrical stimulation (FES), neuromuscular electrical stimulation (NMES), and/or in receiving electromyography (EMG) signals includes a sleeve and electrodes. The sleeve is sized and shaped to be worn on a human arm, and comprises a stretchable fabric The electrodes are secured with the sleeve and positioned to contact skin of the human arm when the sleeve is worn on the human arm. An electronic circuit is configured to operate the electrodes. The electronic circuit includes relays connecting the electrodes with a stimulator for performing FES or NMES, and EMG readout circuitry connecting the electrodes with an EMG amplifier. The relays are closed during FES or NMES to connect the stimulator with the electrodes. The relays are open during EMG readout to isolate the stimulator from the EMG amplifier.
