Abstract: An electrical cord plug assembly for inhibiting the removal of an inserted male electrical cord plug having at least one exposed electrical contact is disclosed. The device comprises a housing, a retention member, a biasing member, and a user actuation member. The retention member is movable between an engaged position, where the retention member engages an opening in the electrical contact of the male plug, and a disengaged position where the retention member disengages from the opening. The biasing member biases the retention member towards the engaged position. In the engaged position, the male plug is substantially inhibited from removal from the plug assembly. The actuation member engages the biasing member so as to allow a user to move the retention member to the disengaged position.

Abstract: A plug retention apparatus for use in securing two plug members together to prevent undesired disengagement. The plug retention apparatus is affixed to a first plug member using a retention ring which provides a means for adjustable positioning via a threaded coupling to facilitate securing a second plug member to the first plug member. A plug clamp may be rotatably positioned about the second plug member retaining the plug members in a desired position.

Abstract: A hand-held fluorescent lamp assembly powered by typical line supply of 120 VAC, 60 Hz via an attached power cord and employing multiple commonly available fluorescent lamps. The assembly includes switches to independently control the multiple fluorescent lamps. The assembly includes lightweight solid state power regulation components. The power regulation circuit employs a self-oscillating circuit that is approximately matched in frequency of oscillation to the natural frequency of the fluorescent lamp load to automatically ignite the fluorescent lamps. The power regulation circuit includes circuit elements to automatically protect the ballast circuit and lamps from overdrawing in the run state and from abnormal load conditions.
