Abstract: A conduit assembly, including a first conduit segment defining a passage therethrough; a first housing affixed to the first conduit segment within the passage; a first plurality of electrical conductors attached to the first housing; a second conduit segment rotatably coupled to the first conduit segment; a second housing affixed to the second conduit; and a second plurality of electrical conductors attached to the second housing, where the second plurality of electrical conductors are in electrical communication with and rotatable about the first plurality of electrical conductors.

Abstract: A personal propulsion device adapted to achieve flight by discharging a fluid, including a passenger assembly adapted to support an individual person; at least one fluid discharge nozzle coupled to the passenger assembly, where the nozzle is movable with respect to the passenger assembly to define a range of motion, and where the nozzle is biased towards at least one position in the range of motion.

Abstract: A personal propulsion system, including an assembly adapted to support a passenger and achieve flight through the discharge of pressurized fluid; and a pressurized fluid source in fluid communication with the assembly, where the pressurized fluid source does not achieve flight, and where the pressurized fluid source is constructed at least in part from one or more ballistic armor materials.

Abstract: A personal propulsion device, including a passenger assembly configured to support a plurality of passengers, the passenger assembly including one or more nozzles adapted to discharge pressurized fluid; and a pressurized fluid source in fluid communication with the passenger assembly, where the passenger assembly is capable of achieving flight by discharging pressurized fluid provided by the pressurized fluid source. The pressurized fluid source may be a personal watercraft, and the passenger assembly may be configured to support two passengers positioned side-by-side, one in front of the other, or facing different directions.

Abstract: A personal propulsion device, including a platform configured to support a passenger's body; and at least one fluid discharge nozzle coupled to the platform and angled with respect to the platform, where the angle defined between the nozzle and the platform is between approximately 95° and 120°; where the personal propulsion device is configured to receive pressurized fluid from a remote pressurized fluid source, and where the personal propulsion device is configured to achieve flight.
