| 20120325981 | Railway Signaling System with Redundant Controllers - Disclosed is a railway signaling system for controlling a load. In accordance with the teachings of this invention, the system comprises a first autonomous controller and a second autonomous controller which is redundant with the first controller, each controller connectable to the load such that there is no single point of failure. The first and second controllers operable in either an on-line mode wherein both power outputs provide power to the load or an off-line mode wherein a single power output does not provide power to the load. On-line controllers monitor current therethrough. When both controllers are on-line, the current between the two controller is imbalanced up to a threshold limit, if the threshold limit is exceeded by one controller, that controller will go off line, and if the first controller is off-line and the second controller is on-line, the second controller monitors output voltages of the off-line controller to ascertain that the output voltages are zero. | 12-27-2012 |
| 20130206924 | KEY LOCK AND ARRANGEMENT HAVING A KEY LOCK - A key lock which can be used particularly flexibly and cost-effectively has a communication device for wire-free linking of the key lock to an actuating mechanism. The key lock further has a cable-independent power supply device for autonomously providing the electrical power required for extended operation of the key lock. | 08-15-2013 |
| 20140138495 | RAILWAY SIGNALING SYSTEM WITH REDUNDANT CONTROLLERS - Disclosed is a method of controlling a load in a railway signaling system, the method comprising providing a first autonomous controller connectable to the load and a second autonomous controller which is redundant with the first controller such that there is no single point of failure; operating the first and second controllers in one of two modes. There is an on-line mode wherein both controllers provide power to the load to control the load such that current through the load is shared between the first and second controllers. There is an off-line mode wherein a single controller does not provide power to the load and the other controller continues to operate on-line to control the load, whereby control of the load is uninterrupted. | 05-22-2014 |
