Abstract
An electronic pedometer is constructed by a combination of a calculator of the hand-held type and a weighted balance switch closed in response to the strides taken by the person wearing or carrying the pedometer. The stride-actuated switch is connected in parallel with the contacts of a function key of the calculator, such as the 'add' or 'subtract' key. The distance covered by the wearer in a normal stride is entered in a conventional fashion into the calculator by operation of the appropriate data entry keys. Then, each time a step is taken by the user, this data is added or subtracted (in accordance with the function selected by the user) to continuously provide an indication of the distance traveled or distance remaining to be traveled. Alternatively, the calculator may be used to provide a unit count of each step taken and this total then may be multiplied in the calculator by a constant corresponding to the average distance of each step taken by the user.
