Title (EN) COMMUNICATION SYSTEM
(FR) SYSTEME DE COMMUNICATION
Abstract:
(EN) A communication system especially for coaching swimmers comprises a hand set which the coach uses to summon up a swimmer or swimmers to be instructed by means of generated tones and a thing worn by each swimmer to be instructed which contains electronic amplifying means and audio transducers. To water proof the electronics they are enclosed in a sealed enclosure and then in the latex of a swimming cap. Batteries used in the circuitry can be recharged without breaking the sealing by using a strong magnetic field to break through the water-proofing and drive a constant current battery charging arrangement.
(FR) Un système de communication, notamment pour entraîner des nageurs, comporte un combiné que l'entraîneur utilise pour stimuler un ou plusieurs nageurs à qui il donne des instructions en produisant des sons, et un objet porté par chaque nageur et contenant des moyens d'amplification électronique et des transducteurs audio. Afin de rendre étanche le circuit électronique, ce dernier est enfermé dans un boîtier scellé, puis intégré dans le latex d'un bonnet de bain. Les piles utilisées dans le circuit peuvent être rechargées sans rompre l'étanchéité en utilisant un champ magnétique puissant capable de traverser le revêtement d'imperméabilisation et d'exciter un agencement de chargement de piles à courant constant.
