  • Patent number: 7027897
    Abstract: A mass transit vehicle traction motor control system includes an automatic control block for receiving and processing a tachometer signal having a first resonance signal superimposed thereon to produce a rate request signal having a corresponding second resonance signal superimposed thereon. A filter is provided for decreasing an amplitude of the second resonance signal whereupon the rate request signal is isolated therefrom. A communication and control block and a propulsion and control block co-act to process the isolated rate request signal to produce a speed control signal that is configured to cause a traction motor of a mass transit vehicle to provide motive force to the mass transit vehicle at a rate related to the value of the speed control signal.

  • Patent number: 5116262
    Abstract: An arrangement for mounting high voltage electrical devices. A generally planar member made of electrically insulating material is provided with a uniform grid of recesses. Mounting plugs are selectively insertable into desired ones of the recesses of the member. Each mounting plug includes an insulating body which is configured to be removably fixed in a desired one of the recesses of the member. A conductive pin extends through the insulating body and presents a mounting terminal on each side of the member when the plug is inserted into one of the recesses. Each mounting terminal on at least one side of the member is configured for affixing thereto both an electrical lead and a mounting device for an electrical component to be attached to the member.

  • Patent number: 4138669
    Abstract: A remote monitoring and controlling system for sub-sea oil/gas production equipment includes a control station for generating an appropriate digital code signal to accomplish a desired function and a cooperating remote station station system for receiving the signal and processing it in order to perform the selected function after the receipt of the signal is confirmed at the control system and an execute digital signal is generated at the control system.
