Abstract: A device and method is shown and described for the purpose of providing situational awareness to third party observers through a portable emergency light system. The system includes a casing, a power supply, a control panel, and a series of lights. The lights are configured to illuminate according to one or more elected illumination patterns. The particular patterns may represent given situations or conditions, and provide notice to observers related to a warning, caution, or defined perimeter. The sequential blinking, brightness, and coloring of the emitted light may vary. Multiple units may be connected to provide an elongated series of lights. This is ideally useful for roadside assistance and emergency personnel.

Abstract: The present invention provides methods and systems for preventing the misconfiguration of OSRP and OS/ISIS networks using a NMS, including: configuring a GNE with an address and NE ID for the NMS; forwarding topology information through a management interface to a NMS server; at the NMS server, copying a topology database of all NEs that are connected to the GNE; and, at the NMS server, launching NE mediators for all of the NEs in the topology database. Each NE mediator includes a listener that listens for updates and topology changes within the network.

Abstract: A current interrupter for use in the power transmission and distribution industry that uses an electrically conductive handle to route current through the current interrupter when the current interrupter shunts current away from opening electrical switch contacts. The electrically conductive handle eliminates the previously used dedicated electrical contacts. The current interrupter has a spring, known as a charging spring, to enhance its opening sequence. The charging spring in conjunction with the guide springs in the interrupter provides an added opening force allowing the internal contacts of the current interrupter to open faster, thus reducing the amount of internal arcing experienced by the current interrupter. The interrupter has a driving bracket a portion of which is electrically conductive. As the handle moves along the conductive portion of the driving bracket, the contacts remain closed even as the handle approaches that point on the bracket past which the contacts will separate.

Abstract: A driving bracket for use in the power transmission and distribution industry that uses an electrically conductive portion to route current to a handle of a current interrupter when the current interrupter shunts current away from opening electrical switch contacts. The electrically conductive portion is mounted on a swing arm assembly and the driving bracket and the handle eliminate the previously used dedicated electrical contacts as well as various internal wiring required to connect those contacts.

Abstract: A fork lift truck (10) has a truck body (12), a lift mechanism (14) connected to the truck body (12) by means of a vertically extending pivot (52) and means (24) for turning the lift mechanism (14) relative to the truck body (12) about said pivot (52) to steer the truck (10), the truck body (12) having a pair of rear ground engaging wheels (16) mounted on transverse axes, the lifting mechanism (14) having a single ground engaging front wheel (40) mounted centrally on a transverse axis, the front wheel (40) having independent drive means (44, 46).
