Abstract
A compact, miniature instrument for providing biofeedback information of interest to a user. The instrument is comprised of a wrist-watch size unit, which includes a temperature sensor for sensing the user's external skin temperature and a finger-mountable unit, which includes a heart beat sensor for sensing the user's heart beat. Processing circuitry is provided for computing various biofeedback parameters of interest to the user, including pulse rate, time rate of change in pulse rate and time rate of change in external skin temperature. Timekeeping circuitry is provided for keeping track of various time-related parameters, such as time of day and calendar date. A display is provided for selectively displaying biofeedback and time-related information to the user.
