1. In an electronic timepiece having a source of constant frequency signals pulses, a time computing circuit coupled to the source of constant frequency signal pulses and producing time information in binary coded decimal form, an electro-optical digital display, a decoder circuit coupling the time computer circuit to the display, and a first manually operated switch coupled to the time computing circuit for energizing the display from the time computing circuit in response to operation of such first switch, an auxiliary calorie calculator data system including in combination:

  • a main storage counter for storing numerical data indicative of net calories;

    a rate controlling circuit coupling said main counter with said source of constant frequency pulses for decrementing the count in said main counter at a predetermined rate;

    an auxiliary digital counter;

    means including at least a second manually operated switch coupled with said auxiliary counter and with said source of constant frequency pulses to store a count in said auxiliary counter corresponding to caloric intake, said second switch further being coupled with said auxiliary counter for energizing said display from the output of said auxiliary counter in response to operation of said second switch;

    means controlled by said second switch for transferring the count from said auxiliary counter to said main counter to increase the count in said main counter by the amount of the count stored in said auxiliary counter;

    calorie rate expenditure circuit means including a third manually operated switch for effecting storage of a count in said auxiliary counter corresponding to the rate of expenditure of calories;

    a latch memory circuit coupled with said auxiliary counter and operated by said third switch for storing the count present in said auxiliary counter;

    a calorie rate down-counter coupled with said latch memory circuit and with said rate controlling circuit for temporarily storing the calorie count stored in said latch memory circuit and for varying the rate at which the count in the main counter is decremented by said rate controlling circuit directly proportional to the count stored in said latch memory circuit; and

    a fourth manually operated switch coupled with said main counter for energizing said display from said main counter in response to operation of said fourth switch.
