  • Patent number: 7236338
    Abstract: A system and method are provided for remotely detecting and locating faults in a power system. The system includes at least one slave controller and at least one supplemental protection module. The slave controller is disposed proximate at least one load and electrically connected to the loads via at least one conductor. More particularly, the slave controller includes at least one solid-state switch capable of controllably altering the input current to the loads. The slave controller also includes at least one measuring element for measuring at least one parameter associated with the loads and the solid-state switches. The solid-state switch can then controllably alter the input current to the loads according to the parameter. The supplemental protection modules are electrically connected to the conductors between the slave controller and the loads. In this regard, the supplemental protection modules can detects at least one fault in at least one conductor.

  • Patent number: 7005995
    Abstract: A system is provided for remotely detecting and locating damaged conductors. The system includes at least one slave controller disposed proximate at least one load and electrically connected to the loads via at least one conductor. The slave controller includes at least one solid-state switch capable of controllably altering the input current to the loads, as well as at least one measuring element for measuring at least one parameter associated with the loads and the solid-state switches. The solid-state switch can controllably alter the input current to the loads according to the parameters. The system also includes at least one damaged wire detector electrically connected to the conductors between the slave controller and the loads. The damaged wire detector is capable of detecting and/or locating at least one damaged conductor.

  • Patent number: 6816758
    Abstract: A programmable controller is provided that is capable of interfacing with a remote master controller, where the programmable controller is capable of controlling an input current to at least one load that is proximate the programmable controller. The programmable controller includes at least one solid-state switch capable of controllably altering the input current to the loads. The programmable controller also includes at least one measuring element for measuring at least one parameter associated with the loads and the solid-state switches, such as the current through the solid-state switches, the current through and voltage drop across the loads and/or the temperature at or around the solid-state switches. Additionally, the programmable controller includes a processing element capable of controlling the solid-state switches, such as by controlling the current through the solid-state switches to the loads.

  • Patent number: 4360175
    Abstract: An aircraft weather vane and mooring device having a turntable rotatably mounted about a depending central shaft. A friction brake assembly engages the center shaft to prevent rotation of the turntable under normal wind conditions. The turntable comprises a plurality of radially extending crossarms having a low profile configuration. The crossarms are supported for rotation on ground engaging rollers at spaced-apart locations along the crossarms. Weather panels can be detachably secured between adjacent crossarm members.
