A solid-state electronic wristwatch with a digital display includes additional circuitry to permit utilization of the display and the source of constant frequency signals of the watch to expand its operation to a calorie calculator. The calorie calculator components include a counter circuit for entering a count indicative of caloric intake, circuitry for entering calorie expenditure rate in terms of calories expended per hour, and a main calorie counter into which the calorie input information is entered and from which counts representative of calories consumed are removed at a rate determined by the calorie expenditure rate entered into the system. The watch display may be activated to display the calories being added, the calorie expenditure rate, and the net calories unconsumed on demand by the user. The watch also, if desired, may include a calendar display which also shares the common digital display elements used to display the time and calorie information.
A calorie monitoring device is provided for providing a visual output which compares the number of calories burned by an individual versus the calorie intake for the individual. The device has a keyboard which functions as a first input to input the calorie intake of the individual. The calorie intake input is applied to a first calculator through an interface and the calculator adds the calorie intake input to the total calorie intake in storage and displays the new total calorie intake. The keyboard also functions as a second input to receive a value indicative of the calories burned per unit of time for the individual under normal conditions. This value is applied to a second calculator through the interface circuit. The second calculator calculates and displays the total number of calories burned during a total time period which extends over a plurality of the predetermined time periods. Thus, the second calculator provides an output which is a real time display of the total calories burned by the individual. The device also includes an exercise mode circuit which controls the second calculator to add, to the total calories burned, additional calories when the individual exercises. The exercise mode circuit can be adjusted to add calories burned which are indicative of the level of exercise being performed.
An electronic calorie counter is disclosed which provides a digital readout of the rate of caloric consumption with exercise by the user by sensing the vertical component of the motion of the user, and translating that motion into electronic impulses. The vertical component of the user's motion is constantly detected using a magneto-electric transducer in combination with means for defining an opto-electric axis in the transducer. The output of the opto-electric means is combined with a clock-controlled gate to provide a burst of impulses over a unit of time which is proportional to the vertical acceleration sensed. The gate output is supplied to a program-controlled processor utilizing a mathematical equation derived to analyze caloric consumption in humans with exercise. The processor is also responsive to several input switches indicating the physical parameters of the individual user in calculating caloric consumption. The microprocessor output, as displayed, comprises the calories consumed by the user over a fixed period of time.
A net calorie calculating apparatus is provided for calculating the calories burned by a person, the calories consumed by the person and the difference therebetween. The apparatus includes a calculator for performing mathematical calculations, the calculator including a keyboard and a display. A first memory is coupled to the calculator and stores rate data representing the rate of calories burned for different predetermined human activities. A second memory is coupled to the calculator and stores calorie content data representing the number of calories per unit of various predetermined kinds of food. A program memory stores programs for controlling the calculator for the calculation of calorie burn rate, total calories burned and net calories, and an interface couples the program memory to the calculator. A control means controls the operation of the program memory to inititate various calculations in the calculator.
A scale with use reminder and weight change messages including a scale portion capable of accurately determining a weight of a person standing thereon. The scale portion includes a display for registering the weight of the person standing thereon. A central processing unit is disposed interiorly of the scale portion. The central processing unit is capable of storing the weight of the person standing on the scale portion on a first day and comparing it with the weight of the person standing on the scale portion on a next day and illustrating both on the display along with a difference between the two. The central processing unit includes programmed messages.
An apparatus for checking food intake, which advises user of amount of a particular food or constituent thereof which may still be eaten during remainder of measuring period, including a counter and a register.
