ELECTRO-BIOMETRIC METHODS AND APPARATUS

摘要

A method and apparatus for tracking changes in an electro-cardiologic signal using a signal processing device having a sensor. The method comprises communicatively coupling the sensor of the signal processing device with a subject; reading into a memory an electro-cardiologic signal of the subject via the sensor and the signal processing device to create an enrolled electro-cardiologic signal; tracking, via the signal processing device, possible variations in the electro-cardiologic signal of the subject over a time period to modify the enrolled electro-cardiologic signal; and adjusting the enrolled electro-cardiologic signal when changes in the electro-cardiologic signal occur.
