Some demonstrative embodiments include a wireless connector and devices and/or systems utilizing one or more wireless connectors. For example, a device may include a wireless connector to be coupled to another device for communicating data with the other device, the wireless connector including a wireless communication unit to communicate the data over a wireless communication link, for example, a short-range wireless communication link, e.g. at a multi-gigabit-per second (MGbs) rate.

A pressure compensator for compensating volume variations of a medium is provided. The pressure compensator has a first compensator part and a second compensator part. The first compensator part encloses a first volume and the second compensator part encloses a second volume. The first and second volumes are in flow communication. The first compensator part includes a first bellows portion and the second compensator part includes a second bellows portion. A moveable element is further provided, to which the first bellows portion and the second bellows portion are mechanically coupled such that movement of the moveably element along a predetermined axis results in the compression of one of the bellows portions and in the expansion of the other of the bellows portions.

In an electrical cord reel, a rotatable member can rotate about a winding axis to spool and unspool a linear material. An input power connector can couple to an electrical power source. An output power connector on the rotatable member can couple to an electrical cord at least partially wound about the rotatable member. A switch is adjustable to allow or prevent electrical current flow from the input power connector to the output power connector. In an aspect, the electrical cord reel includes an electric cord comprising a first power wire, a second power wire, and a signal wire. A method of controlling the electric cord spool system includes energizing the first power wire and the signal wire. The method further includes determining a continuity of the signal wire. The method further includes de-energizing the first power wire when determining discontinuity of the signal wire.

A method of packaging an elongated article, in particular a heating cable (4, 15) into a coil (Figs 4, 5) by starting out from a bight (8) made at the mid point (19) of a cable length and winding the two parts of the cable in parallel into a coil. The purpose of making such package is to facilitate dewinding and installation of the cable in two parallel tracks, starting out from the two cable ends and completing the installation with the bight.
