    • A combined power and fiber optic cable can be terminated and connected to a second such cable. The male plug, in addition to its two male blades and hollow ground pin, carries a fiber optic conductor spring mounted to the plug. The receptacle has the normal female contact and ground pin contact to receive the blades and ground pin, respectively. The receptacle further carries a fiber optic conductor. When the male plug and receptacle are joined the electrical circuit between electrical conductors joined to the plug and receptacle are closed. In addition the end faces of the fiber optic conductors within the plug and receptacle are joined. The spring allows the fiber optic conductor of the plug to stay in intimate contact with the fiber optic conductor of the receptacle.

    • A connector for communications systems has four input terminals and four output terminals, each arranged in an ordered array. A circuit electrically couples each input terminal to the respective output terminal and cancels crosstalk induced across the adjacent connector terminals. The circuit includes four conductive paths between the respective pairs of terminals. Each conductive path includes a plurality of conductive strips arranged in a zig-zag pattern with alternating strips mounted on opposite sides of the substrate and connected end-to-end by conductive devices passing through the substrate. The first and third paths are in relatively close proximity with conductive strips of the first path crossing conductive strips of the third path on opposite sides of the substrate to simulate a twisted wiring pair. The second and fourth paths are in relatively close proximity with conductive strips of the second path crossing conductive strips of the fourth path on opposite sides of the substrate to simulate a twist wiring pair.

    • An arc fault detector comprised as a stand alone unit and in combination with a ground fault circuit interrupter (GFCI) functions to provide protection from potentially dangerous arc fault conditions. When combined with a GFCI, the combination arc fault/ground fault circuit interrupter (AFCI/GFCI) provides protection from both arc fault and ground fault conditions. A single transformer is used to detect faults between neutral and ground and arc faults. An impedance splits the current flow into two portions so as to generate differential current proportional to the current flowing through the conductors. An early arcing detector periodically tests the AC line for high impedance between the device and a main breaker panel. The AFCI/GFCI device detects both AC line frequencies and high frequencies associated with arcing. Both average and instantaneous values of both AC line frequency and high frequency arcing signals are processed to generate an arc fault signal. The device allows the arc detector to differentiate between destructive high level arcing and low level arcing such as generated by typical household appliances and equipment. This serves to decrease the occurrence of false tripping. The device also includes a timer circuit, which permits the user to temporarily disable the arc detector, and includes communication circuitry to permit the device to communicate the occurrence and location of the arc fault to a centralized monitoring station.
