Abstract: Disclosed is an flexible extension cord with a power indicator in the female receptacle and a ground continuity indicator in the male plug.

Abstract: A method for remotely restoring inoperative data communications is disclosed. The method includes generating a predetermined sequence of signals at a first Communications unit. The method further includes keying an output of a transmitter on and off at the first communications unit with the predetermined sequence of signals and conveying a transmission of the predetermined sequence of signals to a second communications unit. The method also includes recognizing the predetermined sequence of signals at the second communications unit as indicative of inoperability of the second communications unit and, responsive to the recognized predetermined sequence of signals, outputting a signal to attempt to restore inoperative data communications at said second communications unit.

Abstract: A system and method for remotely restoring inoperative data communications are disclosed, which causes the transmitter to transmit over the physical link a predetermined sequence of signals that can be detected at the receiver. Responsive to the detected sequence of signals, the receiver can initiate an internal reset command to restore the communication of data. As one example, a system for remotely restoring inoperative data communications is disclosed, which includes a first laser transceiver unit located in a head end, and a second laser transceiver unit remotely located in a node end, and an optical transmission medium connected between the head end and the node end. For this example, the head end is the host end of a distributed base station system for a cellular radiotelephone network, the node end includes the cellular transmitter/receiver (remote radio head) and antenna components, and the optical transmission medium is a fiber optic cable.

Abstract: Packaging for a coiled electrical extension cord having a body portion with a plurality of side walls, end walls extending from the side walls, a bottom wall extending between the side walls along an edge thereof and a top wall extending from each side wall along an opposite edge wherein the top walls and side walls have tabs and mating slots for securing the packaging together and the top walls form an opening along a top surface of the packaging at opposite ends thereof allowing the electrical extension cord to extend out of the packaging.
