Electronic calorie counter

Abstract

A calorie counter which is adapted to be constructed in the shape of a wristwatch and which includes a pulse detector for detecting the heart pulses. The calorie counter circuit consists of seven sections; time base, clock, data accumulator, data multiplier, translator, data selector and the display. The heart pulse rate is received, amplified and filtered into uniform shaped waves which are applied to the data accumulator section which totalizes the pulse count and determines the actual pulse rate which is held in a storage latch and updated at one-minute intervals. The actual pulse rate is applied to both the data multiplier section and the binary to BCD decoders. The data multiplier section includes means for presetting the calorie counter to the user's metabolism. The actual pulse rate from the data accumulator is multiplied by the preset metabolism factor and applied to the look-up memory of the translator which provides a direct calorie reading for every heart pulse rate from 40 pulses per minute to 199 pulses per minute based on the preset metabolism combination. The binary to BCD decoder converts the pulse count stored in the data accumulator latch in a binary format to a binary coded decimal format and represents the actual heart pulse rate which is applied to the data selector for numerical display. The binary coded decimal output information from the clock, translator, and binary to BCD decoder is applied to the data selector for synchronizing. Manual control is used to select the desired format of display; i.e., time, pulses per minute, or calorie total.
