An underwater utility line, and associated systems and methods are disclosed. The underwater utility line can include an adjustably buoyant tube. The underwater utility line can also include a transmission line to transfer energy disposed in an interior of the adjustably buoyant tube. The underwater utility line can further include a gas source and a controller to control the gas provided by the gas source to alter the buoyancy of the adjustably buoyant tube.

A cable system is provided which is configured with both electric wires and a fluid conduit running through the axial passage of a surrounding flexible sheath of the cable. The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid.

A bicycle hose structure comprises a tubular main body and a first electrical conductor. The tubular main body defines a through-hole, an inner peripheral surface and an outer peripheral surface. The through-hole is configured to arrange a force transmitting element provided so as to transmit operating force. The first electrical conductor is provided at least radially inwardly of the outer peripheral surface and has an end portion configured to be electrically connected to a bicycle component.

Disclosed herein are liquid conductive wires and methods for making and using the same. Liquid conductive wires can be used in flexible, reconfigurable, dynamic and transparent electronic devices. Liquid conductive wires can be used in a variety of systems including, but not limited to, soft robotics.

The presently disclosed embodiments relate to insufflation and irrigation conduits for vessel harvesting systems and methods of their use. In particular, the present disclosure relates to a system having a combined cabling for providing gases, liquids, and/or electrical power to an attached medical device and method of use.

A tube and conductor set includes a polymeric tube having a radially outward facing surface and a conductor having a polymeric sheath in which the polymeric sheath has a radially outward facing surface. The radially outward facing surface of the polymeric tube is bonded to the radially outward facing surface of the polymeric sheath of the conductor over an axial length, except for one or more unbonded intermediate axial gaps. These one or more unbonded intermediate axial gaps provide a starting point for the separation of one of the ends of the polymeric tube from one of the ends the conductor. It is contemplated that more than one tube and/or conductor can be bonded and that each line of bonding could have such unbonded intermediate axial gaps to facilitate ease of separation.

A composite flat cable, having in cross-section a major side, may include an outer sheath; two main electrical conductors; and two ducts for fluid circulation configured to circulate fluid. A composite flat cable may include two ducts configured to circulate fluid; a first main electrical conductor on a first side of the two ducts; a second main electrical conductor on a second side of the two ducts; and a sheath around the two ducts, the first main electrical conductor, and second main electrical conductor. A solar cogeneration plant may include at least one cell configured to produce electric current, connected to a plant for distribution of electrical energy and of heated fluid by a composite flat cable.

A cable vent connector configured for venting an electric motor is provided. The cable vent connector includes an input for receiving a motor-side cable that includes a vent tube and a plurality of electrical conductors; a body configured for venting the vent tube to a local atmosphere, thus permitting an interior of the electric motor to reach pressure equilibrium; and a port for connecting the plurality of electrical conductors with a drive-side cable configured to drive the electric motor. A venting system and a production system are disclosed.
