Disclosed are a wall structure and a lighting system using the same. The wall structure in accordance with one embodiment of the present invention includes an installation surface on which an electronic apparatus is installed; a first conductive attachment part provided at the installation surface to be attached to the electronic apparatus, and electrically connected with a first terminal of a power source configured to supply power to the electronic apparatus; and a second conductive attachment part provided at the installation surface to be attached to the electronic apparatus, spaced from the first conductive attachment part, and electrically connected with a second terminal of the power source configured to supply power to the electronic apparatus.

Herein described is at least a system for generating one or more control signals based on a voltage provided by an energy storage device. Based on the one or more control signals, the system may selectively enable flow of current through one of: a) a first circuitry when the voltage is equal to or greater than a threshold value, and b) a second circuitry when the voltage is less than the threshold value, wherein the flow of the current through the second circuitry upconverts the voltage associated with the current from a first value to a second value.

An active composite panel assembly is configured to transfer electrical signals from a source to an electrical device. The active composite panel assembly includes a composite layer, and an active layer secured to the composite layer. The active layer is configured to receive and conduct the electrical signals.

The present invention relates to a cable tray section which allows being successively coupled to another tray section (1) having similar features, without needing accessories or angle requirements on the horizontal plane, comprising longitudinal metal wires (10); U-shaped transverse metal wires (20); at least one anchoring element (30) installed between the longitudinal wires (10), attached to the last and next to last transverse wires (20), and comprising a single metal wire (31) close to the next to last transverse wire (20); and a pair of straight sections (32, 32′) parallel to one another; where the straight sections (32, 32′) project with respect to the last transverse wire (20), forming a rectangular section (33) perpendicular to the straight sections (32, 32′), such that there is established a free space (40) between the last transverse wire (20) and said rectangular section (33); said space (40) having a dimension corresponding to the thickness of a transverse wire (20).

An enhanced apparatus and method for securing a wire to a pulling cable for pulling wire. Specifically, the pulling cable and wire are attached via a pulling head body. The wire is inserted into an end of the pulling head body and secured by crimping the pulling head body against the wire. Further, crimp zone indicators positioned on the outer surface of the pulling head body indicate the optimal zone of crimping to achieve substantial contact between the pulling head body and the wire. A pulling cable is secured to the pulling head body via a ball swage that comprises a tapped surface.

A first power storage portion is configured to store power generated by a generator in a vehicle, and to supply power to a motor for starting an engine and an electric device in the vehicle. A second power storage portion is connected to the first power storage portion in parallel, and configured to store power generated by the generator, and to supply power to the electric device in the vehicle. A first switch is inserted in a path between those portions. A diode is connected in parallel with the first switch such that a cathode side thereof is connected to the second power storage portion side. The controlling portion monitors a voltage of the first power storage portion and a voltage of the second power storage portion, and detects an abnormal state of the switch by comparing a voltage difference therebetween with a forward voltage drop of the diode.

A cable management device for mounting to a telecommunications fixture includes an outer barrel disposed over an inner barrel, one of the outer barrel and the inner barrel defining a plurality of discrete detents positioned in a stacked arrangement axially along an length thereof, and the other of the outer barrel and the inner barrel defining at least one flexible cantilever arm defining a tab configured to lock into a selected one of the detents for allowing adjustment of a length of the cable management device.

An airplane, which includes an airframe and a full-segregated thrust hybrid propulsion system mounted on the airframe. The propulsion system includes: one or more sustainer thrust producers; a plurality of electrically powered thrust producers disposed in predetermined positions as a means for providing additional thrust to the airplane, and to supplement airflow over the wings, flaps, and roll control devices of said airplane; whereby increasing the lift of the wing surfaces and providing enhanced control in the roll axis. The trust producers operate independently from one another, with no aerodynamic, electrical or mechanical inter-connection. Safety is enhanced by the ability of either the sustainer thrust producer(s), or the electrically powered augmentation thrust producers to sustain flight to a suitable landing area, should the other system fail.

A busbar support system having means for preventing rotation of a threaded shaft which connects busbars to the busbar support and means to prevent compressive forces resulting for the bolted connection from causing damage to the busbar support.
