Abstract
A calorie counter which is adapted to be constructed in the shape of a wristwatch and which includes a pulse detector mounted in the band of the watch to detect the heart pulses. The calorie counter circuit is comprised of six sections; the time base, clock, data accumulator, translator, data selector, and the display. The heart pulses are detected by the pulse detector and are supplied to the calorie counter circuit which has been preprogramed for each pulse rate from 40 pulses/minute to 199 pulses/minute. The calorie count for each minute of time represents a total of calorie count for a predetermined length of time. The accumulated information is converted by the driver circuit which converts and processes the binary coded decimal information into drive lines for the display numbers in the display section. A manual control is used to select the desired format of display; i.e., time, calorie/minute, or calories total.
