SENSING SYSTEM AND METHOD FOR ELECTROPHYSIOLOGICAL SENSING BY CAPACITIVE COUPLING WITH ESTIMATION OF THE ELECTRODE TO SKIN COUPLING
A sensing system and method uses a sense electrode arrangement for coupling to a surface of a body such that the sense electrode arrangement and the body (and the spacing between them) define a coupling capacitance. First and second sensing circuits have different transfer functions and generate first and second outputs. These outputs are processed to determine the coupling capacitance. The electrophysiological signal being monitored is also acquired by one or both of the sensing circuits. In this way, the quality of the electrode coupling can be determined in a simple and passive manner.

Integrated ECG Electrode and Antenna Radiator
Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.

Method and system for detecting an event and determine information about it (like its strength) using resistive state changes of a memristor
The present invention provides a method and system for processing data from an event, such as a neurological event. When a neurological event occurs, a spike in a neural waveform is generated. The spike can be detected and used to determine information about the neurological event. The method uses data values from a resistive switching component capable of undergoing a resistive state change when a voltage is applied to it. The data values represent a sequence of resistive state changes of the resistive switching component which correspond to the neurological event. The method further comprises processing the received data values to identify a resistive state change corresponding to the neurological event and to obtain information about the neurological event. Thus, a method and system for processing neural spikes is provided.
