    摘要： There is provided a voltage or current sensing device. An exemplary voltage or current sensing device includes a drive circuitry configured to deliver a drive current to a magnetic core operably coupled with a conductor, for driving the core to cyclical magnetic saturation. The device also includes sense circuitry configured to receive a voltage signal corresponding to an application current in the conductor. The device also includes signal processing circuitry configured to sample the voltage signal, wherein a first sample is in phase with the drive current and a second sample is out of phase with the drive current. The device also includes a feedback loop configured to deliver a compensation current to the magnetic core, wherein the compensation current is configured to balance the magnetic core and wherein the compensation current is based at least in part on the first sample in phase with the drive current.

    摘要： A multi-use wayside railway control system for installation and use in operating wayside railway equipment in a railway wayside application selected from among a plurality of differing railway wayside applications usable in the control system. The system includes detectors responsive to and generating data indicative of operating conditions of the selected wayside application A controller receives data from the detectors and is responsive to the data for operating the wayside equipment. A programmed processor associated with the controller includes a software program storage device for storing a plurality of separately selectable operating programs, each of the operating programs comprising application specific information for a selected wayside application and corresponding configuration of wayside equipment. A control display unit enables selection of one of the stored operating programs compatible with the selected wayside application and corresponding wayside equipment configuration for use by the controller.
