Radio controlled engine kill switch
First Claim
1. An engine deactivation system for use with user operated water vehicles, said system having:
- at least one waterproof transmitter, each of said at least one transmitter being a portable device transmitting a constant individually identifiable signal powered by an independent power supply, said signal being water sensitive and blocked from said receiver when said transmitter enters the water;
a waterproof receiver, said receiver receiving and recognizing said individually identifiable signal from each of said at least one transmitter, said receiver having cut-off means, said cut-off means being connected to an engine and having a run mode and a deactivation mode, said deactivation mode shutting down said engine; and
an antenna, said antenna transmitting said signal between said transmitter and said receiver;
manual reset means, said manual reset means over riding said receiver cut-off means to manually place said cut-off means in said run mode or said deactivation mode;
wherein receipt of said signal by said receiver maintains said cut-off means in a run mode and interruption of said constant signal from one of said at least one transmitter immediately activates said deactivation mode, thereby requiring reactivation of said vehicle by reinstating transmission of said signal to place said cut-off means in said run mode or over riding said cut-off means with said manual reset means.

Abstract
A engine kill switch system has a transmitter and receiver which are linked through specific transmitted codes within a frequency. The receiver is mounted directly on the boat and wired to an engine kill switch, maintaining the switch in the closed position as long as a signal is received from all of the activated transmitters. Once the transmitter signal is unintentionally deactivated, the receiver shuts down the engine. A range adjustment allows the separation distance between the transmitter and receiver to be changed, dependent upon the size of the boat and end use. A strobe and audio warning can also be attached to the receiver and activated simultaneously with, or as an alternative to, the deactivation of the engine. Automatic transmitter activation and deactivation can be provided through storage ports tied to the receiver. The transmitter is a battery powered remote device carried by a user. The transmitter has a programmed unique code recognized by the receiver. The system, or individual components, are provided with deactivation codes entered through an input device. The system can also be used as an antitheft device simply by removal of one transmitter, thereby rendering the engine inoperable.

1. An engine deactivation system for use with user operated water vehicles, said system having:
-
at least one waterproof transmitter, each of said at least one transmitter being a portable device transmitting a constant individually identifiable signal powered by an independent power supply, said signal being water sensitive and blocked from said receiver when said transmitter enters the water; a waterproof receiver, said receiver receiving and recognizing said individually identifiable signal from each of said at least one transmitter, said receiver having cut-off means, said cut-off means being connected to an engine and having a run mode and a deactivation mode, said deactivation mode shutting down said engine; and an antenna, said antenna transmitting said signal between said transmitter and said receiver; manual reset means, said manual reset means over riding said receiver cut-off means to manually place said cut-off means in said run mode or said deactivation mode; wherein receipt of said signal by said receiver maintains said cut-off means in a run mode and interruption of said constant signal from one of said at least one transmitter immediately activates said deactivation mode, thereby requiring reactivation of said vehicle by reinstating transmission of said signal to place said cut-off means in said run mode or over riding said cut-off means with said manual reset means. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. The method of disabling an engine by the elimination of an individually recognized signal using a device having:
-
at least one waterproof transmitter, each of said at least one waterproof transmitter being a portable device transmitting a constant individually identifiable signal powered by an independent power supply, said signal having a low transmission through water;
at least one indicator light, said indicator light designating the power status of said transmitter;a waterproof receiver, said receiver receiving and recognizing said identifiable signal from each of said transmitters, said receiver having cut-off means, said cut-off means being connected to an engine and having a run mode and a deactivation mode, said deactivation mode shutting down said engine;
on-off means, said on-off means deactivating said receiver;
at least one indicator light, said indicator light designating the power status of said receiver;
manual reset means, said manual reset means over riding said receiver cut-off means to manually place said cut-off means in said run mode or in said deactivation mode;distance control means, said distance control means varying the maximum transmission distance between said transmitter and said receiver, determining at what distance said signal is blocked from said receiver, placing said cut-off means in said deactivation mode; an antenna, said antenna transmitting said signal between said transmitter and said receiver; comprising the steps of; a) activating said receiver through said on-off means; b) verifying the power status of said transmitter; c) attaching said transmitter to a user; d) verifying that said receiver is receiving said individually identifiable signal; wherein receipt of said signal by said receiver maintains said cut-off means in a run mode and interruption of said constant signal from any one of said at least one transmitter, immediately activates said deactivation mode, thereby requiring reactivation of said vehicle by reinstating transmission of said signal to place said cut-off means in said run mode or over riding said cut-off means with, said manual reset means.

21. A signal transmission device having:
-
at least one waterproof transmitter, each of said at least one transmitters being a portable device transmitting a constant individually identifiable signal powered by an independent power supply, said signal having a low transmission through water;
on/off means, said on/off means controlling said independent supply;a waterproof receiver, said receiver receiving and recognizing said identifiable signal from each of said transmitters, and having; cut-off means, said cut-off means being connected to an engine and having a run mode and a deactivation mode, said deactivation mode deactivating said engine, on-off means, said on-off means deactivating said receiver, coding means, said coding means taking said individually identifiable signal from each of said at least one transmitter and coding said receiver to recognize said signal; over ride means, said over ride means allowing said cut-off means to be in said run mode without receiving said signal; at least one indicator light, said indicator light designating the power status of said receiver and said at least one transmitter, said at least one indicator light being color coded to designate at least one of recharging, transmitting or low battery status checks; distance control means, said distance control means varying the maximum transmission distance between said transmitter and said receiver; audio alarm means, said audio alarm means being activated by said deactivation mode; visual alarm means, said visual alarm means being activated by said deactivation mode; an antenna, said antenna transmitting said signal between said transmitter and said receiver; said transmitter being proximate said receiver when not in use, and initiating transmission of said signal upon separation of said transmitter from said receiver and ceasing transmission when proximate said receiver wherein receipt of said signal from all separated transmitters by said receiver maintains said cut-off means in a run mode and interruption of said constant signal by said transmitter entering the water, or being taken beyond transmission range, from any one of said transmitters initiates said deactivation mode, and either reinstatement of transmission of said signal or activation of said over ride means places said cut-off means in said run mode.
