  • Patent number: 11724724
    Abstract: A system for controlling one or more vital wayside devices of a railway network, comprising one or more vital switches, each vital switch being comprised in or operatively connected to an associated device of the one or more vital wayside devices, and a controller which is configured to control the one or more vital wayside devices. The controller is connected to each of the one or more vital switches by means of at least one optical fiber cable and is configured to output one or more light command signals over the at least one optical fiber cable, and each vital switch is configured to switch from an open status to a closed status to provide power and ground to the associated vital wayside device upon receiving at least one corresponding light command signal outputted by the controller for commanding an action of the associated vital wayside device.

  • Patent number: 10988151
    Abstract: A system controls a level crossing of a railway track installation. The railway track installation includes at least one track. The system includes at least two magnetometers associated with the at least one track and placed at corners of a crossing area between the at least one track and a road. The system also includes a level crossing control unit configured for receiving data from the magnetometers. Each magnetometer is arranged to detect a respective magnetic field vector of the earth's magnetic field and to send data representative of the magnetic field vector to the control unit. The control unit is configured to elaborate the data to detect changes in the magnetic field vectors due to the presence of a train in the crossing area and to control the level crossing as a function of the detected changes.

  • Patent number: 10533288
    Abstract: The railroad track wire connection is configured for electrically connecting a first element of a railroad installation to a second element of the railroad installation, the first element and the second element being electrically conductive, at least one of the first element and the second element being a rail of a line of rails of a railroad track of the railroad installation.

  • Patent number: 8316329
    Abstract: Double patterning is achieved with a single reticle while maintaining the integrity of in-scribe patterns and without blading the reticle. In-scribe structures may or may not be double patterning. For example, elements such as electrical test structures might have features that are so closely spaced that double pattering is desired. However, elements such as optical alignment marks might not require double patterning. For those elements for which double patterning is not desired, a first sub-array of the reticle has a pattern for the element, whereas the corresponding location in a second sub-array has a blank. By the corresponding location, it is meant the location on the reticle that would be exposed to the same target region to which the element would be exposed if the reticle were used for double patterning. Thus, the blank prevents target region from being exposed more than once.
