Described are systems and methods for magnetically assisted boom refueling. In certain examples, a magnetic refueling receiver is disclosed that includes a refueling receptacle configured to receive a portion of a refueling boom and a receptacle magnet disposed around at least a portion of a perimeter of the refueling receptacle. In another example, a magnetic refueling boom is disclosed that includes a refueling boom structure that includes a first end configured to be inserted into a refueling receiver and a pipe magnet disposed around at least a portion of a perimeter of the refueling boom structure.

Connector assemblies including a first subassembly having a recessed portion and a pair of locator tracks and a second subassembly having a pair of locator projections, vacuum assemblies including these connector assemblies, and methods of using the same are provided herein.

A faucet includes a base and a spout. The base is configured to be coupled to a mounting surface. The spout is rotatably coupled to the base. The spout includes a plurality of magnetic joints each including a different number of magnetic members, and a plurality of conduits rotatably coupled to each other by a magnetic joint of the plurality of magnetic joints. The spout extends from the base to a free end configured to discharge a fluid. The plurality of magnetic joints are arranged such that the number of magnetic members on each magnetic joint progressively increases from the free end to the base.

An air valve assembly includes a housing defining an internal channel, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, a sealing member defining a first inflation aperture, the plunger member slidably received by the first inflation aperture, a second deflation aperture defined by the housing and in fluid communication with the internal channel, and a deflation control member slidably connected to the housing, the deflation control member configured to selectively seal the second deflation aperture.

A hose connector is disclosed that provides a magnetized connection of hoses, tubes, cables, ducts, pipes, chains, straps, wires, twine, cord and/or rope creating a continuation in length for versatile and extended flow for, but not limited to, watering needs eliminating conventional connector threads currently requiring multiple turns to release or attach or existing pronged coupling requiring a degree of hand agility and strength. Thereby the disclosed matter provides the means for a fast, single motion attachment or twisting detachment of, but not limited to hose, tube, cable, duct, pipe, chain, strap, wire, twine, cord and/or rope ends without requiring the hand strength or precision that some conventional hose, tube, cable, duct, twine, cord, and/or rope connectors may require. There may be any combination of connecting the ends of hoses, tubes, cables, ducts, pipes, chains, straps, wires, twines, cords, and/or ropes. In some scenarios, flow is not required.

A connecting system for connecting components in a vehicle includes a first elongate element with a first connecting face at a first end, and a second elongate element with a second connecting face at a second end. The first and second elements each comprise holding devices distributed along an annular connecting line. The connecting faces are congruent. The connecting faces and holding devices are configured to be brought into a flush superficial contact when the orientations of the elongate elements coincide, and the mutually opposing holding devices then connect with one another. One of the elements has a length adjustment component configured to change a position of the respective connecting face in a longitudinal direction of the respective element. The connecting faces comprise at least one pair of connectable interfaces which correlate with one another in pairs for transfer of a fluid, electrical or optical signals or electrical current.

A headset for a hydration system is disclosed. The headset includes a fluid conduit adapted to connect to a distal end of a hydration system supply tube, and a magnetic quick connect having an upstream and a downstream coupling member. The upstream and downstream coupling members have a common mating axis and together define a portion of the fluid conduit. The upstream member also includes an off-axis arm that may be rotated about the mating axis without decoupling the coupling members. A headgear mount for use in headsets for hydration systems, such as the disclosed headset, is also provided.

A vehicle exhaust evacuation system includes an adapter secured to an end of a vehicle tailpipe and a nozzle assembly secured to the end of a flexible hose for carrying vehicle exhaust outside of a building. The nozzle assembly has an aluminum cartridge removably secured in a rubber boot. Magnet assemblies are secured to the aluminum cartridge. Openings in the adapter allow ambient air to flow over the magnet assemblies to lengthen the life of the magnets.

A magnetically positioned dryer vent coupling is adapted for use in combination with a clothes dryer. The dryer vent coupling includes a flexible exhaust duct, a first mounting substrate, and a second mounting substrate. The first mounting substrate is located at one end of the flexible exhaust duct and includes a first magnet. The second mounting substrate is adapted for residing proximate one of the dryer exhaust port and wall port, and includes a second magnet. When moved into close proximity, the first and second magnets magnetically attract to one another to self-align and self-assemble the first and second mounting substrates of the dryer vent coupling, such that the first and second mounting substrates create an audible snapping sound when engaged thereby indicating a close magnetic seal at the dryer vent coupling.

A headset for a hydration system is disclosed. The headset includes a fluid conduit adapted to connect to a distal end of a hydration system supply tube, and a magnetic quick connect having an upstream and a downstream coupling member. The upstream and downstream coupling members have a common mating axis and together define a portion of the fluid conduit. The upstream member also includes an off-axis arm that may be rotated about the mating axis without decoupling the coupling members. A headgear mount for use in headsets for hydration systems, such as the disclosed headset, is also provided.
