Abstract: An electrical power distribution unit for overload prevention and a method for preventing overload of the electrical power distribution unit. The power distribution unit includes: (i) a plurality of sockets, each socket being an electrical power outlet socket, each socket having a plurality of receptacles for receiving corresponding pins of a power plug; (ii) a mechanical disabling mechanism configured to disable each socket that is unoccupied by a respective power plug; and (iii) an excess power detector configured to detect an aggregate power drawn from the sockets. The method includes: monitoring, by the excess power detector, a first aggregate power drawn from the sockets; and determining that the first aggregate power exceeds a predetermined first threshold and in response, actuating the mechanical disabling mechanism to disable each socket that is unoccupied by a respective power plug.

Abstract: A power distribution unit (PDU) having a connector to connect to an input power supply and a plurality of power outlet sockets for receiving plugs having a number of pins. Each power outlet socket has a mechanical locking mechanism movable between a locked position and an unlocked position when a plug is inserted into the power outlet socket to lock and unlock a plug pin in the power outlet socket. Absent actuation the locked position is adopted. Each power outlet socket includes an externally, manually actuatable, first release element, and an internally, electrically actuatable, second release element. A power sensor detects whether or not power is being drawn and, for power outlet sockets which currently host a plug and are not drawing power, the second release element is actuated by the PDU so as to unlock the mechanical locking mechanism, thereby freeing up the associated plugs for removal.

Abstract: A flooring element is provided for a raised floor including removable flooring panels and a supporting structure with a load bearing surface. The flooring element includes a warning element operable for moving between an inactive position in which the warning element is substantially concealed by the surface and an active position in which the warning element projects beyond the surface to form a visual hazard warning indicator. The flooring element may be for example a flooring panel, a stringer, a pedestal, an insert for a pedestal or an insert for inserting between a sub-floor void and a flooring panel.

Abstract: A method, system and computer program product. A first computer device identifies a notifiable management event relating to the first computer device, wherein the first computer device is unable to notify a management device of the notifiable management event via a management network because the first computer device is unable to connect to the management network. The first computer device sends, to a second computer device via a broadcast or multicast communication, an event notification of the notifiable management event. The first computer device receives, from the second computer device via a first unicast communication, an acknowledgement of the event notification, wherein the second computer device is able to connect to the management network. The broadcast or multicast communication and the first unicast communication each use a short-range wireless communications technology.

Abstract: A key for operating a mechanical lock, which key includes a head portion for holding by a user, a lock-engaging portion for inserting into the lock for operating the lock by the application of a turning force, and a joining portion between the head portion and the lock-engaging portion and fixing the head portion to the lock-engaging portion. The joining portion includes a shape memory material, which reversibly deforms without breakage when a first turning force on the key is exceeded, where the first turning force is lower than a second turning force. The second turning force being a turning force which if exceeded causes breakage of the lock-engaging portion or the head portion. The shape memory material may exhibit a superelastic effect in which the shape is restored when the turning force ceases, or shape memory effect in which the shape is restored on heating above a state-transition temperature.

Abstract: A safety mechanism is provided for an electrical equipment rack. The rack has a frame with a vertical frame element including vertically spaced at intervals mounting points which are apertures for accepting mounting pegs of a frame mountable portion of an electrical equipment unit mounting rail. The safety mechanism has a vertical strip member mounted for vertical movement adjacent the vertical frame element, and the vertical strip member includes spaced apertures corresponding to the apertures on the vertical frame element. The vertical strip member is movable between a fully raised position and a lowered position. The safety mechanism further includes a raising mechanism for raising the vertical strip member from a lowered position to the fully raised position.

Abstract: A safety apparatus for an electrical equipment rack includes a retractable safety device for preventing, when in an operational position, the extending of an extendable rail and an electrical equipment unit mounted thereon from a position internal to the rack to a position external to the rack, and for allowing the same when in a non-operational position. The position of the retractable safety device is linked to the position of a retractable rack support such that when the retractable rack support is lowered in its operative position the retractable safety device is in a non-operational position, and when it is raised in a raised inoperative position the retractable safety device is in an operational position preventing the extending of the extendable rail and an electrical equipment unit mounted thereon to a position external to the rack.
