    Patent number: 5374921
    Abstract: A beacon is contained in a waterproof housing which is devoid of any electrical contact points. At a location at which a signal is to be applied to or received from the beacon, the housing is made sufficiently thin to allow light to pass therethrough. A light energy transmitter coupled to receive the signal to be transmitted into or out of the housing is located immediately adjacent or abutted against the translucent portion of the housing. A light energy receiver is similarly disposed adjacent or abutted against the other side of the housing, to receive the light energy. In this manner no electrical contacts need pass through the housing, and the beacon circuit is entirely protected by the waterproof housing, from water, soap, sweat, body oils, etc.
