A system includes a pump, a liquid sensing switch linked to the pump and suspended in an area, the liquid sensing switch including a large surface area upper bare uninsulated stainless steel sensor plate linked to electronics, a large surface area lower bare uninsulated stainless steel sensor plate linked to the electronics, and a large surface area ground linked to the electronics, the pump activated when a liquid level in the area rises above a position of the lower bare uninsulated stainless steel sensor plate and a position of the upper bare uninsulated stainless steel lower sensor plate, causing a current to pass between the two sensor plates.

A liquid sensing switch comprising an upper sensor plate linked to electronics, a lower sensor plate linked to the electronics, and a ground linked to the electronics, wherein a pump is activated when a liquid level rises above a position of the lower sensor plate and above a position of the upper sensor plate, causing a current to pass between the two sensor plates.

A system and method for lighting a surface, for example a deck of a boat, spa, swim spa, pool, watercraft or vehicle, using backlighting such that decorative or other desired patterns of light may be created by forming cuts, outlines, thin sections, or voids in an overlay that is applied to the lighted surface, allowing light to pass through or around portions of the overlay material. In an exemplary use of the system and method of the invention, the surface may be the surface of a boat or spa. The surface may comprise transparent or translucent materials, allowing light from a first side of the decking, or light that is generated within the decking, to pass through the decking and to emanate from a second decking side, where the light may be blocked, partially blocked, or allowed to pass through the overlay material in any desired pattern or shape.

In some embodiments, a lighting assembly including at least one light-emitting device positioned within a housing is disclosed, wherein the housing is designed to allow an ambient environment to pass into the housing and transfer heat from the at least one light-emitting device. The light-emitting area of the light-emitting device may be sealed from the ambient environment. In some embodiments, the housing may include at least one recess, port, or other opening configured to allow a liquid or gas to promote heat transfer from the light-emitting device. In some embodiments, a vehicle, a marine system, or other systems may include at least one lighting assembly as contemplated herein.

A system for illuminating a class of watersport boards. The system includes a light on the top of the board and a light-transmitting fin on the underside of the board. The board-top light and the light-transmitting fin are fastened together with fasteners that pass through the board. The board-top light contains a battery and energizes the light-transmitting fin through an energy-coupling. Electrically conductive paths and translucent channels are both discussed as energy couplings. An inductive charging connector is provided for charging the battery. Remaining service-time is reported to a user based on battery charge. Additional sensors, such as light sensors, and a microcontroller allow the unit to turn on automatically when ambient light falls below a programmed threshold.

A motorized watercraft is a vehicle that is used to transport a user across the water. The motorized watercraft includes a floating board, a control unit, at least one electrically accessible system, a power source, and at least one conduit stringer. The floating board allows a user to float above the water. The at least one electrically accessible system may include a propulsion system, lights, or other features. The control unit is mounted to the deck of the floating board and is used to regulate the speed of the propulsion system and may be used to control lights which are mounted into the floating board. The power source is used to provide the energy needed for running the propulsion system and the lights. The conduit stringer runs through the floating board, strengthening the floating board and providing a channel through which wiring may run.

The remote control boat with fish finder is designed to give fishermen that are fishing from the bank a way to determine the depth of the water they are fishing, to locate fish within the water they are fishing, and to determine structures and features under the water where fish may be located. The remote control boat with fish finder incorporates a remote controlled boat with an integral fish finder, LED running lights, and an LED spot light. The remote control boat with fish finder comprises a boat, an RC system, a fish finder transponder, a PDA, and a battery.

The disclosure relates to a marine searchlight system with wiretapping remote controllers including a main body assembly, a wiretapping box and two remote controllers. The main body assembly includes a control motherboard configured to control a lighting module and a driving module. The control motherboard includes a DC power module and a signal receiving module. The DC power module provides a DC power. The signal receiving module receives a control signal. The wiretapping box is electrically connected to the DC power module and the signal receiving module. The two remote controllers are electrically connected to the control motherboard through the wiretapping box. The DC power module provides the DC power to two remote controllers respectively. Each of the two remote controllers allows to transmit the control signal to the signal receiving module through the wiretapping box, so that the control motherboard can control the lighting module and the driving module.
