Abstract
A buoy for marine vessels that is responsive to a transmitted RF signal of a set frequency consisting of an RF receiver disposed within the buoy and tuned to a set frequency of the transmitted RF signal and an antenna coupled to the input of the RF receiver. A switching circuit is coupled to the RF receiver, and a lamp is disposed on the buoy so that when the RF receiver receives a signal at the set frequency, it will operate said switching circuit and turn on said lamp. The buoy may be a pick-up buoy having an elongated stem on the top of the buoy, and containing the antenna. The lamp can also be mounted on the end of the antenna. A sound source coupled to the output of the switching circuit can sound an audible signal in response to the transmitted RF signal.
Claims8
A mooring locating system for marine vessels that is responsive to a transmitted RF signal of a set frequency transmitted from the marine vessel, comprising:
- a floating pick-up buoy for retrieval by the marine vessle having a buoyant, water tight container and including an elongated stem disposed vertically on the top of said buoy;
- a stem extending downwardly from said floating pick-up buoy for attachment to mooring lines of a fixed mooring so that upon retrieval of the pick-up buoy the vessel can be secured to its mooring;
- an RF receiver disposed within the water tight container and tuned to the set frequency of the transmitted RF signal, said receiver producing a signal at its output in response to the RF signal;
- an antenna wrapped along the length of said vertical elongated stem and coupled to the input of said RF receiver;
- a switching circuit coupled to the RF receiver and responsive to the output signal of said receiver to produce a switching signal;
- a lamp disposed at the free end of said elongated stem and having its input coupled to the output of said switching circuit and responsive to the switching signal thereof to turn on said lamp;
- and
- a battery power source disposed within said buoyant container and coupled to said RF receiver, said switching circuit, and said lamp.
