Pedometer
First Claim
1. An apparatus for measuring the distance covered by walking or running on foot adapted to be put within shoes or a portable case, comprising two separate, complementary electronic devices supplied by cells, wherein one of said devices is a slave unit fixed on one shoe and is capable of generating signals through suitable emitting means, while the other of said devices is a master unit fixed on another shoe, and is capable of receiving said signals through suitable receiving means, and of storing and processing said signals so as to convert said signals into a binary code, in so doing being capable of calculating a runner'"'"'s or pedestrian'"'"'s completed distance and average and maximum speeds, and automatically displaying the distance and speeds, said signals being modulated and directional so that the extent to which they are received by the master unit is proportional to the distance between the emitting and receiving means, wherein means for displaying the processed data are further provided.
