  • Patent number: 9054475
    Abstract: A pair of brackets for a multiple pin fluorescent bulb. A first bracket has two horizontal apertures on an inside face of the bracket and each bracket is sized and spaced from the other to permit insertion engagement and holding of two end pins of one end of the fluorescent bulb. The horizontal apertures permit the other end of the bulb to be vertically moved for engagement with an opposite facing bracket which has two vertical slots with a lower end open access. The vertical slots permit two other horizontally aligned end pins of the fluorescent bulb to be inserted therein by an upward vertical movement. Electrically conductive spring like metal members extend into a path of the vertical slots such that they electrically engage and hold the opposite end pins of the fluorescent bulb. A releasing element pushed the spring like members apart for pin and bulb removal.

  • Patent number: 8033873
    Abstract: A system for locating corresponding ends of a communications or data patch cable used to conduct a signal between computing or telecommunications devices. The invention provides a physical indication of the location of an opposite end of a given patch cable when a switching means on the first end of the same cable is activated. The invention utilizes an existing pair of wires in category-type cables to send a DC voltage when activated to illuminate a light emitting diode in the opposite end of a patch cable thereby providing an immediate indication of the location of the termination of the opposite end of a patch cable making it possible to visually identify a cable without removing the cable from service or from connection of the modular plugs on either end of the cable.
