The invention relates to a removable stabilizer for a spacer casing (24a-24f) of an electrical installation of the GIS type (20), the spacer casing (24a-24f) comprising a first opening (33) as well as a conductor (30b) provided with a bore (34), the removable stabilizer (29) comprising a plug (29a) configured to be introduced via the first opening (33) into the spacer casing (24a-24f), the plug being designed to penetrate into the bore (34) of the conductor (30b) so as to block said conductor (30b) against moving in translation after said spacer casing (24a-24f) has been put to atmospheric pressure.

When an indication is received from a user input, a name of an audio source from an ordered list of audio sources to which a headset is currently connected is output. Whenever a successive indication is received within a predefined amount of time, the name of the next wireless audio source in the list is output. If the next wireless audio source in the list is the last wireless audio source in the list, and the successive indication from the user input is received before the elapsed time exceeds the predefined value, the name of the audio source to which the headset is currently connected is output as the next selected wireless audio source in the list. When an amount of time greater than the predefined value elapses without a successive indication from the user input, the last wireless audio source that had its name output is connected.

Provided is a selection device including an acquisition section for acquiring digital selection signals, and an output section for outputting selection signals to respective unit cells, each unit cell capable of being commanded to output the value zero. The selection device is characterized in that: each selection signal is for commanding the unit cell to output a value corresponding to that selection signal; the sum of the values to be output as commanded by the respective selection signals, which are output to the respective unit cells, is a value determined in association with the digital selection signal; and if the output corresponding to the digital selection signal is the value zero, then selection signals each commanding to output a non-zero value (N) are output to some of the unit cells.

Cabling of equipment at a work site may require lengthy or bulky lines or cables to be run from a power source. A system of cabling control to reduce the length and weight of cables or lines is disclosed. The system uses cable assemblies coupled to work site equipment to facilitate quick and easy coupling and decoupling of cables or lines. The disclosed cabling system may provide for more efficient set up or configuration of a location and operation of work site equipment.

Sound control circuit comprising a game port, installed on a digital audiovisual reproduction system managed by an operating system, characterized in that the game port in the sound control circuit is used to create an access to the configuration of the audiovisual reproduction system and/or additional management functions for the audiovisual reproduction system.

Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

A plate having an upper surface and a lower surface, a center point, and an outer perimeter. It further includes a plurality of clips for temporarily securing the plate in an opening in a landscape box. Each of the plurality of clips comprises a limb, extending vertically downward, the limb having the form of a rectangular plate and being upper bound by an upper edge and lower bound by a lower edge, wherein the upper edge is attached to the lower surface of the plate. The limb further includes a foot extending horizontally sideways from the lower edge.
