<p>An apparatus for measuring the distance covered by walking or running on foot adapted to be put within shoes or a portable case, consisting essentially of two separate, complementary electronic devices supplied by cells, one of which (slave) is able to generate signals through suitable emitting means, while the other (master) is able to receive said signals through suitable receiving means and to store and process them so as to calculate the distance covered and the average and maximum speeds, said signals being modulated and directional so that the reception is proportional to the distance between emitting and receiving means, means for displaying the processed data being further provided. The emitting unit (slave) and the receiving unit (master) are provided with automatic self-switching on/off means to avoid any control by the user and at the same time to optimize the consumption of the power supply cells.</p> |
