A winding drum for a line and/or for a line guide device which is adapted to receive and guide at least one line, wherein the drum is rotatable about the longitudinal axis thereof, wherein a first end region of the line and/or line guide device is or can be fixed to the drum and the line and/or line guide device can be wound on to and unwound from the drum by rotation of the winding drum in a winding-on and an unwinding direction about the drum longitudinal axis, wherein there is provided a drive device engaging the winding drum in order upon rotation of the drum in the unwinding direction thereof to exert a return force on the drum for rotation thereof in the winding-on direction. The drive device is in the form of a torsion spring which upon rotation of the drum in the unwinding direction is subjected to torsional stress and by virtue of the torsional stress exerts a torque on the drum for rotation thereof in the winding-on direction and the torsional stress exerts the return force on the drum.

An adapter system is provided that facilitates convenient access to a plurality of adapters, e.g., DVI-D to HDMI adapter(s), Micro-HDMI to HDMI adapter(s), Mini-HDMI to HDMI adapter(s), Mini-DisplayPort to HDMI adapter(s), DisplayPort to HDMI adapter(s), VGA to HDMI adapter(s), MNL to HDMI adapter(s), and/or USB to HDMI adapter(s). The adapter system includes an elongated wire that features a plurality of adapters mounted/secured with respect thereto. The wire is at least partially stored within a housing and extends therefrom. The adapters are mounted/secured with respect to a portion of the wire that extends from the housing. The housing includes a retraction mechanism that facilitates retraction of the wire into the housing for convenient storage thereof. The present disclosure further provides structures that are configured and dimensioned to receive the disclosed housing, e.g., in office, commercial and/or residential environments, thereby facilitating access to the adapters that are mounted/secured with respect to the wire. In use, the disclosed adapter system permits a user to readily access and individually utilize each of the adapters mounted/secured with respect to the wire on an as-needed basis and to store at least the portion of the wire that does not include mounted/secured adapters within a housing. Retraction of the wire into the housing is facilitated by the disclosed retraction mechanism.

A power tether for aerial devices such as balloons or drones operates with as few as a single conductor, providing a ground return by capacitive coupling between the aerial device and a ground plane at a base station. High-frequency, high-voltage power allows significant power transfer through the low capacitance between the aerial station and the ground minimizing the necessary current flow.
