Abstract

The present invention provides a wireless power-supply control assembly 100 for wirelessly controlling a boat'"'"'s main power supply. The assembly 100 comprises an enclosure assembly 110, wherein a latching relay 600 and a wireless-receiver relay 300 are mounted. The wireless receiver relay 300 is controlled by commands from a wireless transmitter and causes the latching relay 600 to connect or disconnect the boat'"'"'s main power. In other embodiments, an ignition-sense relay 400 is also mounted within the enclosure and disconnects power to the wireless-receiver relay 300 when the boats ignition is on. In yet another embodiment, a manual override switch 200 is provided within the enclosure for bypassing the latching relay 600 and manually connecting the boat'"'"'s power.

Claims

1. A wireless power-supply control assembly comprising:

an enclosure comprising a body and a cover, wherein the body and the cover define a hollow cavity;

a wireless-receiver relay mounted to the enclosure within the hollow cavity, the wireless-receiver being adapted to wirelessly receive a command from a wireless transmitter; and

a latching relay mounted to the enclosure within the hollow cavity and coupled to the wireless-receiver relay, the latching relay having a line terminal adapted to be coupled to a common-supply cable from a boat'"'"'s battery and a load terminal adapted to be coupled to a boat'"'"'s power main cable, the latching relay having an open position and a closed position, wherein the latching relay is adapted to connect power from the line terminal to the load terminal when the latching relay is in the closed position and to disconnect power between the line terminal and the load terminal when the latching relay is in the open position;

wherein the wireless-receiver relay is adapted to cause the latching relay to switch between the open and closed positions in response to receiving a wireless command.

2. The wireless power-supply control assembly of claim 1 further comprising:

an ignition-sense relay mounted to the enclosure within the hollow cavity and coupled to the wireless-receiver relay, wherein the ignition-sense relay is adapted to receive a boat'"'"'s ignition-sense signal and adapted to disconnect power to the wireless-receiver relay when the ignition-sense signal indicates that a boat'"'"'s engine is running.

3. The wireless power-supply control assembly of claim 1 further comprising:

an antenna coupled to the wireless-receiver relay, wherein at least a portion of the antenna extends through an opening in the enclosure to the exterior of the enclosure.

4. The wireless power-supply control assembly of claim 3, wherein the opening for the antenna is sealed.

5. The wireless power-supply control assembly of claim 1 further comprising:

a manual override switch mounted to the enclosure and having an open and a closed position, wherein the manual override switch is adapted to bypass the latching relay when in a closed position.

6. The wireless power-supply control assembly of claim 5, wherein the manual override switch is mounted in an opening in the enclosure and the manual override switch is adapted to be selectably positioned in the open or the closed position from the exterior of the enclosure.

7. The wireless power-supply control assembly of claim 1, wherein the latching relay is adapted to remain in its current open or closed position if power is disconnected to the wireless-receiver relay.

8. The wireless power-supply control assembly of claim 1, wherein the latching relay is adapted to remain in its current open or closed position without using any power.

9. The wireless power-supply control assembly of claim 1, wherein the latching relay is a high-current magnetic latching relay.

10. The wireless power-supply control assembly of claim 1, wherein the wireless-receiver relay is adapted to consume approximately 10 nano amperes or less of current while listening for a wireless command.

11. The wireless power-supply control assembly of claim 1, wherein the wireless-receiver relay is a polarity switching circuit and is adapted to consume approximately 0.3 amperes or less of current while switching polarity.

12. The wireless power-supply control assembly of claim 1 further comprising at least one liquid tight strain relief fitting mounted in an opening in the enclosure and adapted for receiving a common-supply cable.

13. The wireless power-supply control assembly of claim 1, wherein the hollow interior is adapted to be substantially waterproof when the enclosure is operational.

14. The wireless power-supply control assembly of claim 1, wherein the enclosure is substantially box shaped.

15. A water vehicle comprising:

a hull, gunnel, steering mechanism, and propulsion mechanism used to propel the vehicle;

a vehicle power system comprising an engine and a battery, an ignition sensor, and a power main; and

a wireless power-supply control assembly comprising;

an enclosure comprising a body and a cover, wherein the body and the cover define a hollow cavity;

a wireless-receiver relay mounted to the enclosure within the hollow cavity, the wireless-receiver adapted to wirelessly receive a command from a wireless transmitter;

an ignition-sense relay mounted to the enclosure within the hollow cavity and coupled to the wireless-receiver relay, wherein the ignition-sense relay is coupled to the ignition sensor and adapted to disconnect power to the wireless-receiver relay when a signal from the ignition sensor is indicative that the engine is running; and

a latching relay mounted to the enclosure within the hollow cavity and coupled to the wireless-receiver relay, the latching relay having a line terminal coupled to the battery and a load terminal coupled to the power main, the latching relay having an open and a closed positions, wherein the latching relay is adapted to connect power from the line terminal to the load terminal when the latching relay is in the closed position and disconnect power from the line terminal to the load terminal when the latching relay is in the open position;

wherein the wireless-receiver relay is adapted to cause the latching relay to switch between the open and closed positions in response to receiving a wireless command only while the engine is not running.

16. The water vehicle of claim 15 further comprising a manual battery switch mounted to the cover of the enclosure and connected in serial with the wireless power-supply control assembly.
