Abstract
A display system for indicating sailing data to an operator of a small sized sailing boat in which a speed sensor in the hull transmits pulses to a speed measuring device which stores the data in a memory. The sailing data is periodically transmitted to a receiver worn by the boat operator either on his wrist or some conveniently viewable position.
Claims3
A display system to indicate the sailing data, such as, speed of a small size boat comprising:
- a speed detecting sensor set up on the hull,
- a speed measuring means connected to said sensor in which pulses therefrom are received and processed,
- a memory means connected to said speed measuring means in which sailing data thus processed is stored,
- a transmitting means connected to said memory means in which the data thus stored is read, modulated and radiotransmitted periodically,
- a receiving means of wristwatch type, separated from said transmitting means, in which the data thus transmitted is received and displayed on an indicator,
- the radio communication being done by using weak electric waves.
