Abstract: A method of determining information concerning the identity of an individual comprising measuring at least one biometric of the individual comprising at least one bio-potential waveform generated by the individual's heart, extracting a plurality of characteristics from the bio-potential waveform comprising any of an approximate location of a point of a P peak, an approximate location of a Q-point of a QRS peak system, an approximate location of an R-point of a QRS peak system, an approximate location of an S-point of a QRS peak system, an approximate location of a point of a T peak, using the characteristics to calculate at least one waveform parameter, comparing at least one calculated waveform parameter with at least one previously-acquired waveform parameter to generate a score, and using the score to determine information concerning the identity of the individual.

Abstract: A flexible biomedical surface electrode comprises an insulating substrate (10), a conductive electrode layer (12) screen-printed on the substrate, and an insulating masking layer (14) on the electrode layer. The masking layer is configured to expose selected regions (16) of the electrode layer. An electrically conductive adhesive gel layer (18) on the masking layer makes electrical contact with the exposed regions of the electrode layer.

Abstract: A two-part sensor (1) comprising a first part comprising a sensing device (3) which senses information, a second part comprising a receiving device (5) which receives a measure of the information, and a connector (7) comprising at least one first portion (21) which is magnetic and is attached to one of the sensing device and the receiving device, and at least one second portion (23) which is magnetizable and is attached to an other of the sensing device and the receiving device, wherein the first portion and the second portion are connectable and disconnectable to connect and disconnect the sensing device and the receiving device.
