A retractable data cable assembly is provided, which includes a cable, a winding assembly, a movable assembly and a housing defining an accommodating cavity where the winding assembly and the movable assembly are arranged. The cable is wound around the winding assembly and exposed out of the housing. The winding assembly includes a winder rotatable with respect to the housing. The movable assembly is disposed on a side of the winder and positioned to connect to the housing. The movable assembly includes a transmission assembly and an auxiliary member respectively coupled with the winder and the transmission assembly. The auxiliary member produces elastic deformation to provide the transmission assembly with a preload force for swinging toward or away from the side of the auxiliary member. The storage of the retractable data cable assembly is more convenient.

An emergency lighting assembly includes a drum that has a chute extending into the drum. A spool is rotatably disposed within the drum. The spool is biased to rotate in a first direction and the spool is urgeable to rotate in a second direction. A locking mechanism is movably integrated into the drum to inhibit the spool from rotating and to facilitate the spool to rotate. A light rope is attached to the spool and the light rope can be pulled outwardly through the chute thereby facilitating the light rope to be positioned on the roadway. The light rope is illuminated when the light rope is turned on to visually alert motorists on the roadway to the hazard on the roadway. A clasp is attached to the light rope and the clasp is attachable to a support object for retaining the light rope in a desired position on the roadway.

Methods and systems are described for an aerial drone system including a drone system controller, at least one working drone (101), and a plurality of support drones (103). The working drone (101) is operated by the drone system controller (125) to adjust a position of the working drone (101). A tether line (105) coupled to the working drone (101) provides electrical power to the working drone (101). The support drones (103) are each coupled to the tether line (105) at a different location along the tether line (105) forming a tethered aerial drone system. Each support (drone 103) supports a portion of the weight of the tether line (105) and is operated by the drone system controller (125) to adjust the position of the tether line (105) by adjusting the position of one or more of the support drones (103).

A wire harness routing apparatus disclosed by the present specification is a wire harness routing apparatus (10) that is to be attached to a rotation platform (80) that allows a seat (S) to be rotated with respect to a base portion (90) provided in a vehicle, the wire harness routing apparatus (10) including a wire harness (20) that is arranged between the seat (S) and the base portion (90), and a case (40) that rotates accompanying the rotation of the seat (S) in a state of accommodating the wire harness (20), wherein the case (40) is arranged on the inner side in the radial direction of the rotation platform (80) using the rotation axis of the rotation platform (80) as a reference.

A power cable arrangement, in particular marine power cable, for offshore wind farms, including at least one cable drum device with a cable drum. The power cable arrangement includes at least one power cable wound on the cable drum with at least one cable end configured to pre-installing at a cable connection of a wind energy device. The power cable is wound on the cable drum such that a first section of the power cable is wound inversely to a further section of the power cable.

The invention relates to a spool assembly for use to effectively manage cables and in particular cables for use as part of ultrasonic testing apparatus, The spool assembly allows the cables to be moved between a storage position in which at least part of the cables are located within the housing of the spool assembly and an extended position in which a greater portions of the cables is unwound and extended from the spool assembly. The spool assembly can be used in two modes of operation, a first mode to allow the cables to be wound onto the holder and a second mode in which the holder is biased to wind the cables into the storage position.
