Abstract: A marine vessel lighting system and a method of operating the same. The marine vessel lighting system may include a marine vessel having a switch, a light device that is configured to be coupled to the marine vessel to electrically couple the light device to the switch, and a processor. The lighting system may be configured to operate such that upon the switch being actuated from an off state to an on state, the processor is configured to activate the light device in accordance with a first mode of operation. Furthermore, upon the switch being actuated from the on state to the off state, and then from the off state back to the on state prior to elapse of a predetermined period of time, the processor is configured to activate the light device in accordance with a second mode of operation that is different than the first mode of operation.

Abstract: A visual distress signal device that generates and emits bright light and/or infrared light to alert bystanders during times of distress. The device may be particularly suited for use on boats. The device may comprise a heat sink assembly that includes a screw-on collar that is attached to a housing of the device, such that the screw-on collar dissipates heat generated by electromagnetic radiation emitting elements away from an interior of the housing. The device may be configured for activation by a mobile phone or other mobile device which may be connected to the device via wireless communication. Furthermore, the mobile device may comprise a software application that can be used to alert persons in a contact list regarding the user's location and emergency status.

Abstract: An improved shaft sealing ring for a portable paint gun of the type having an axially movable control shaft for controlling a supply of pressurized air to atomize a stream of paint. The sealing ring has a truncated frustro-conical surface tapering from a radially extending retaining surface toward a front end of the sealing ring and a radially extending flange at a back end of the sealing ring with an outer peripheral groove in an outer surface of the ring body between the flange and the retaining surface. The ring is installed by urging the front face through an opening having a diameter smaller than that of the face, the opening defined by a wall extending radially inwardly as a part of the gun housing. The flange is resiliently deflected to form a seal when the ring is installed. A central bore of the seal is sized to receive the shaft with a seal between the shaft and the ring provided by a ridge extending radially into the bore of the ring at the back end thereof.

Abstract: An improved control shaft seal and air valve for a portable paint gun with the seal having a radial clearance with the shaft except at a shaft sealing surface of limited axial length. The shaft seal has a conical surface radially outward of the shaft sealing surface to provide a sealing surface and also to provide transfer of axial forces at that surface to a radial direction to provide a force to urge the shaft sealing surface against the control shaft. A second conical surface of the seal provides for retention of the seal on an air valve spring when the paint gun is disassembled. An improved air valve for portable paint guns is also disclosed having a rigid axial hub and radial support carrying a relatively flexible rim portion adapted to engage a tapered seating surface in the gun.

Abstract: There is disclosed herein a liquid spray gun which includes an improved heat dissipation system and an improved leakage flow recirculating system.The improved heat dissipation system results from an improved and stronger air flow through the gun housing and around the electromagnetic coils. The improved air flow is created by a venturi or aspiration effect at the spray tip created by the action of the piston pump in spraying liquid at high velocity reducing the air pressure adjacent the tip. The internal portion of the housing communicates with the low pressure area so air in the housing is drawn from the housing to the low pressure area. Vents are provided in the housing adjacent the electromagnetic coils for outside air to be drawn into said housing over said coils and to the low pressure area, thus improving air flow and heat dissipation.
