Abstract: An arc quenching device includes a frame, at least one controlled-arcing device supported by the frame, and at least one contact assembly supported by the frame and electrically connected to the at least one controlled-arcing device. The device further includes a racking mechanism supported by the frame and including a motor and at least one actuator member driven by the motor and configured to engage a feature in an electrical equipment unit compartment to move the arc quenching device within the compartment and engage the at least one contact assembly with a bus of the electrical equipment unit. The arc quenching device may be configured to be installed in a cassette in the electrical equipment unit and the actuator member may be configured to engage a feature of the cassette.

Abstract: A test apparatus includes an output configured to be coupled to a sense input of an arc quenching device control circuit of an arc quenching system, a user interface, and a control circuit configured to generate a simulated sense signal at the output in response to an input at the user interface, the simulated sense signal representing a physical state associated with a fault condition of a bus coupled to the arc quenching system. The simulated sense signal may be configured to cause the arc quenching device control circuit to trigger an arc quenching device of the arc quenching system. The physical state may include, for example, a voltage condition, a current condition, a temperature, a pressure or a light intensity. In some embodiments, the simulated sense signal may include a current indicative of a current passing through a bus to which the arc quenching system is connected.

Abstract: Aspects of the disclosure include a wireless device in a mesh network. The wireless device includes a processing circuit and a transceiver. The processing circuit is configured to update a first selection model based on first operation history information of operating the wireless device in the mesh network, and determine whether the wireless device is to transmit or receive subsequent mesh control information (MCI) of the mesh network during a subsequent MCI transmitting/receiving (Tx/Rx) window based on the first selection model. The transceiver is configured to transmit or receive the subsequent MCI during the subsequent MCI Tx/Rx window as determined based on the first selection model.

Abstract: A system for rendering safe a site above which an individual is operative at height which comprises at least one self-inflating fall arrest unit in a fully inflated state is arranged at a ground location on the site. At least one of the self-inflating fall arrest units in a fully inflated state is linked to at least one other fully inflated self-inflating fall arrest unit. Each of the self-inflating fall arrest units comprise at least one battery-powered fan. A method of rendering safe a site above which an individual is operative at height is also described.

Abstract: Methods, processes, systems, apparatus and devices for delivering two way multimodal serialized comic content media files that uses a multimedia storage and delivery system. The communications utilize multi-modal inputs and multi-modal outputs to generate and access serialized comic content media files over the World Wide Web and telephone mediums with wireless communication devices and desktop computers.

Abstract: A compression sock made from resilient elastic material for the prevention and treatment of foot and ankle injuries. The compression sock having at least two toe sleeves configured to receive one or more toes on the foot. At least one of the toe sleeves having a toe bridge along an upper surface of the toe sleeve and defining a looped opening underneath the toe bridge. A strap configured to pass through the looped opening under the toe bridge so as to be wrapped around the toe sleeve and held in place by the toe bridge. An ankle portion of the sock having a greater density of resilient elastic material than any other portion of the sock so as to provide proprioceptive support to the ankle.

Abstract: Various uses of tetrafluoropropenes, particularly (HFO-1234) in a variety of applications, including refrigeration equipment, are disclosed. These materials are generally useful as refrigerants for heating and cooling, as blowing agents, as aerosol propellants, as solvent composition, and as fire extinguishing and suppressing agents.

Abstract: A panel assembly for an electrical enclosure has a fixed mounting portion and a movable panel portion. The electrical enclosure has an interior substantially sealed from an exterior except at a number of apertures. The panel assembly includes a mounting portion coupled to the enclosure and a panel portion generally disposed over a corresponding one of the number of apertures. The panel portion is movable in a first direction from a first position to a second position by gas formed from an arcing event within the electrical enclosure passing outward through the corresponding aperture. The panel portion is constrained from movement in an opposite second direction due to a portion of the electrical enclosure.
