Abstract: A modularly constructed hand held, utility light is described and taught having a sealed electrical module and a separately attached handle module. In one embodiment. module includes two half shells that when assembled and attached to the electric module. Various embodiments of the handle module may comprise an articulation mechanism configured to allow the user to manipulate the direction of the light provided by the utility light by rotating the utility light in at least one direction. The articulation mechanism may comprise one or more of a ball and socket joint, a ratchet mechanism, or any other suitable device configured to allow a user to manipulate the direction of the light provided by the modular utility light. In another embodiment, the handle module may comprise a strap configured to facilitate cord management and/or allow a user to hang the modular utility light above a work area.

Abstract: A modularly constructed hand held, utility light is described and taught having a sealed electrical module and a separately attached hand-hold module. The hand-hold module includes two half shells that when assembled and attached to the electric module completes the utility light.

Abstract: An adaptive protection algorithm and system for protecting electrical distribution systems traces the flow of power through a distribution system, assigns a value (or rank) to each circuit breaker in the system and then determines the appropriate trip set points based on the assigned rank.

Abstract: An AC line power coupling system secures a conventional plug (700) of an appliance cord or extension cord (702). A adapter (400) is fitted onto the prongs (704) of the cord, and semi-permanently attached with a connector (300) including two half housings (301 and 302) that fasten over the plug and a clamp (200) that holds the cord. The adapter prongs mate, which have a conventional layout, with a special socket (600). The adapter is locked onto the socket by a sleeve (500). The sleeve moves relative to the socket, rotating and axially sliding. When the sleeve is slid onto the protruding cylindrical end of the adapter and rotated, lugs on the inside of the sleeve engage in grooves, locking the adapter to the socket; the sleeve motion is reversed to unlock. The adapter can be plugged into conventional sockets while the connector remains fastened over the plug, but when plugged into the special socket and locked, the cord is prevented from pulling out under tension.
