摘要： An isolation amplification circuit having an input stage circuitry and a control circuitry stage interconnected through a galvanic isolation barrier. The input stage circuitry includes a first filter network and a second filter network for supplying first and second output signals in response to the application of first and second electrical input signals. The input stage circuitry includes a first feedback path configured for applying a first feedback signal to a common node of the first filter network to close a first feedback loop around the first filter network and a second feedback path configured for applying a second feedback signal to a common node of the second filter network to close a second feedback loop around the second filter network.

摘要： 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.

摘要： 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.

摘要： An electrical connector having a main support with a front and back, top and bottom, and left and right opposite the left. Fingers extend forwardly from the front of the main support to a tip. The fingers each have a top and bottom and are arranged from left to right of the main support with gaps defined between them. A flexible circuit board has inner and outer surfaces with electrical leads on the outer surface. Openings are defined through the flexible circuit board between the electrical leads. The flexible circuit board is wrapped around the fingers such that the outer surface of the flexible circuit board is supported on both the top and the bottom of the fingers and the openings in the flexible circuit board are aligned with the gaps between the fingers.

摘要： Multiple wireless sensor assemblies are individually attached to standard biopotential electrodes, which are placeable on a subject's body at locations for biopotential signal recording. The sensor assemblies, which are electrically isolated, simultaneously measure potential voltages from the body sites in accordance with a synchronization. The measured signals are amplified, digitized, and filtered, and then sent wirelessly to a monitoring system. The monitoring system receives multiple sensor signals and constructs biopotential vectors depending on the placement and number of the sensors. The sensor signals are referenced to a common virtual center bias to synthesize a common mode rejection.

摘要： 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.
