Patent

CA 2257520

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.

Appareil permettant de mesurer la distance que l'on parcourt en marchant ou en courant, destiné à être introduit dans des chaussures ou dans un boîtier portatif. Cet appareil consiste essentiellement en deux dispositifs électroniques complémentaires séparés, alimentés par piles, dont l'un (esclave) émet des signaux par l'intermédiaire d'un moyen émetteur approprié, tandis que l'autre (maître) reçoit ces signaux grâce à un moyen récepteur approprié et les stocke et les traite afin de calculer la distance parcourue, ainsi que les vitesses moyenne et maximale. Ces signaux sont modulés et directionnels, de sorte que la réception est proportionnelle à la distance entre l'émetteur et le récepteur. Un moyen d'affichage des données traitées est également prévu. L'unité émettrice (esclave) et l'unité réceptrice (maître) sont pourvues d'un autocommutateur marche/arrêt automatique rendant superflue toute commande par l'utilisateur, tout en permettant d'optimiser la consommation des piles.
