    • A train location system and method of determining track occupancy utilizes inertial measurement inputs, including orthogonal acceleration inputs and turn rate information, in combination with wheel-mounted tachometer information and GPS/DGPS position fixes to provide processed outputs indicative of track occupancy, position, direction of travel, velocity, etc. Various navigation solutions are combined together to provide the desired information outputs using an optimal estimator designed specifically for rail applications and subjected to motion constraints reflecting the physical motion limitations of a locomotive. The system utilizes geo-reconciliation to minimize errors and solutions that identify track occupancy when traveling through a turnout.

    • This invention concerns a sound proof hangar for airplanes with a wide entrance (3) for aircraft (7). To provide a sound barrier at the open side, the entrance opening is limited, at least on one side, by a series of deflecting surfaces (10), the inner edges of which are directed, in horizontal section, towards the hangar interior and the external edges of which are directed laterally. The deflecting surfaces (10) can be moved between a closed position which partly or completely closes the entrance opening (3) and a position which opens the entrance opening (3).

    • A non-ferrous current sensor is used to continuously measure the charging current magnitude in step-graded foil and paper insulation systems used on high voltage measurement and control apparatus such as instrument transformers and on the condenser bushings of power transformers and circuit breakers. The low voltage measured signal is conditioned by an electronic circuit such that it modulates a DC signal in a system current control loop to provide continuous remote monitoring and alarm functions. Remote power is supplied to the sensor and conversion circuits through the current loop. Alarm level thresholds and alarm time delay are embodied in a control device which may be located in a remote location, away from the high voltage equipment. Step-graded insulation systems form a capacitively divided circuit between the high potential and ground. As the dielectric between the foil layers breaks down, the total capacitance of the insulation system increases, producing an increase in the charging current. The sensor detects changes in the charging current through the insulation ground conductor, indicating the degradation of the dielectric properties between the foil layers. Continuous monitoring of the alarm relay contacts provide a means for reporting abnormal conditions and initiating event-based maintenance procedures. The modulation of a standard 4-20 mA current control loop allows for a multiplicity of monitoring equipment to be added to the system for additional data collection and reporting.
    • 有色金属电流传感器用于连续测量用于高压测量和控制装置(如仪表变压器)和电力变压器和断路器的冷凝器衬套上的分级箔和纸绝缘系统的充电电流大小。 低电压测量信号由电子电路调节,使得其在系统电流控制回路中调制DC信号以提供连续的远程监控和报警功能。 远程电源通过电流回路提供给传感器和转换电路。 报警水平阈值和报警时间延迟体现在一个控制设备中,该控制设备可能位于远离高压设备的远程位置。 分级绝缘系统在高电位和地之间形成电容分压电路。 当箔层之间的电介质发生故障时,绝缘系统的总电容增加,产生充电电流的增加。 传感器检测通过绝缘接地导体的充电电流的变化,表明箔层之间的介电性质的劣化。 对报警继电器触点的连续监控提供报告异常情况和启动基于事件的维护程序的方法。 标准4-20 mA电流控制回路的调制允许将多种监控设备添加到系统中,以便进一步的数据采集和报告。
