20140257604 | BRAKING SYSTEM - A brake control unit for a railway vehicle having first and second cores. The first core is responsible for brake control functions and the second core is responsible for communications. A switch controls communication between the second core and a communication bus on the railway vehicle to safeguard the braking function of the first core. The second core only has write access to the communication bus when enabled by the first core, which first core determines whether the system is in a defined safe state to safeguard the braking function. This reduces the testing requirements for new communications software. | 09-11-2014 |
20100063632 | PLATFORM SCREEN DOOR - A control system for a platform screen door system. The platform screen door system includes a door configured to be opened and closed. The control system includes a door drive means and a microprocessor door drive control means configured to control an opening and closing of the door according to a predetermined profile. Also included is at least one probe configured to monitor one or both of the door drive means and a motion of the door. Further included is a controller configured to control the door drive means such that when the controller is in use the controller brakes the door drive means when a signal from the probe is outside a predetermined door operating envelope. | 03-11-2010 |
20090307980 | PLATFORM SCREEN DOOR SYSTEM - A platform screen door system includes a fixed driving panel and at least one door leaf slidable relative to the fixed driving panel. Further included is a telescopic guide including a fixed guide mounted on the fixed driving panel, a moving guide mounted on the at least one door leaf, and a moving intermediate guide mounted on the fixed guide. Also included is a drive means for slidably moving the at least one door leaf from a closed position to an opened position wherein the at least one door leaf overlaps the fixed driving panel. | 12-17-2009 |
20090145325 | PLATFORM SCREEN DOORS - An apparatus and method for controlling the operation of a screen door system. The apparatus includes a first transceiver adapted to be mounted on a train, a second transceiver adapted to be mounted on either a train platform or a portion of the platform screen door system. The first and second transceivers are configured to communicate with each other such that when a train is stopped at the train platform within a predetermined distance of and adjacent to a door of the platform screen door system, a signal is transmitted from the first transceiver to the second transceiver to open the door. When passenger embarkation and debarkation is complete, a signal is transmitted from the first transceiver to the second transceiver to close the door, and when the door is closed and locked, a signal is transmitted to the train to depart. | 06-11-2009 |
