Abstract: A thermal energy removal system is provided to cool a rail of a railway track in a self-powered mode and/or an externally-powered mode. The system comprises a cooling module configured to mount on a side of the rail to remove heat stored inside the rail. The cooling module includes a solid state electrical insulation sandwiched between a plate and a heat sink. The cooling module further includes a first terminal and a second terminal. The first and second terminals to provide an electric energy source based on the heat extracted and harnessed for powering at least one of an electronic circuit, a light source, and a communication device associated with railways infrastructure.

Abstract: A railroad crossing indication device (250) includes a processing unit (350) for receiving and processing data provided by a constant warning time device (40) in communication with a railroad track (20), wherein the data relate to a train approaching the railroad crossing, and a screen unit (300, 400, 500) for displaying information of the train approaching the railroad crossing based upon the data provided by the constant warning time device (40). Furthermore, a railroad crossing indication system (200) and a method (600) for displaying information at railroad crossings are disclosed.

Abstract: A system for operating a gate arm of a railroad crossing gate is provided. The system includes a lever, a spring attached to an extendable gate arm, a cable mechanism including a cable and a crossing mechanism. The lever is movably coupled to the cable and the spring is coupled to the cable. The lever is coupled to the crossing mechanism and the cable is coupled to the crossing mechanism. The cable mechanism is configured to extend and retract the extendable gate arm and the lever is configured to enable the spring to pull the extendable arm out from a retracted position.

Abstract: A system for aligning a bed of an imaging system with an imaging plane. The system includes a laser device which generates a laser beam and a target element having a target detecting surface. The system also includes a reflective element which receives the laser beam. The reflective element includes a reflective detecting surface for detecting a first position of the laser beam. A first parameter of the bed is adjusted until the laser beam is positioned on a first center portion of the reflective detecting surface. In addition, the laser beam is reflected to the target detecting surface to detect a second position of the laser beam. A second parameter of the bed is adjusted until the laser beam is positioned on a second center portion of the target detecting surface to orient the bed substantially perpendicular to the imaging plane.
