    • Open neutral conductor protection of a 3 phase circuit is obtained by coupling the 3 phase conductors and the neutral conductor of the three phase circuit to a high current GFCI and using power from two of the phases of the 3 phase circuit as the source of power for the high current GFCI. A voltage reducing means such as a step down transformer is connected across two phases of the 3-phase circuit to convert the high voltage, such as 208 volts, across the two phases to 120 volts which is used as the input power for the circuit of the High Current GFCI. In operation, the circuit of the GFCI derives its input power from two separate phases of the 3-phase circuit and, therefore, when an open neutral fault occurs, the supply voltage to the GFCI is not interrupted and the GFCI can continue to provide protection for the system.

    • The invention includes a coil support assembly having an insulator interfacing a surface of a shield disposed within a processing chamber. The insulator has an extension which extends through the shield. A second insulator is disposed between the shield and a coil and contacts a protrusion extending from the coil. A fastener is disposed through the first insulator and extends through the second insulator and into the protrusion. The fastener is electrically isolated from the shield by the first insulator. The invention includes coil assemblies containing the described coil support configuration. The invention further includes a method of supporting a coil within a processing chamber having a shield disposed therein. Insulators are inserted to extend from an outer side of the shield through a thickness of the shield. A coil is mounted within the chamber by inserting fasteners through each insulator into bosses which-protrude outwardly from the coil body.

    • A vehicle mounted, navigation device is disclosed. This invention combines a global position system (GPS) with an image capturing system into a portable device that can be optimally mounted within a vehicle. It can be used for land, air and sea vehicles. The image capturing system detects and interprets visual information to provide the vehicle operator with appropriate navigational guidance assistance and to alert operator of potentially hazardous conditions. Additionally, the device has the capability to store consecutive frames of detected, visual information so as to enable the device to be used for accident aftermath analysis and the documentation of an event or scene.

    • A ground fault protection circuit for plural loads connected across a power source with plural branches which can be used where the loads are unbalanced. Each branch includes a ground fault circuit interrupter device that has a common line for the electronics of the GFCI separate from the neutral line from the power source to the load where the common lines for the electronics for the ground circuit interrupter devices in each branch are connected to a common point. The ground fault protection circuit employs plural ground fault circuit interrupter devices and eliminates nuisance tripping. The common line for the electronics for a GFCI is routed through the core of the current sensing transformer of the GFCI. The separate neutral line for the electronics, connecting the common lines for the electronics for plural GFCI devices and routing the common lines for the GFCI electronics through the core of the transformer of each GFCI, eliminate improper GFCI operation due to unbalanced loading. The ground fault protection circuit may be used for a three phase power source.
