  • METHOD AND DEVICE FOR CONTROLLING THE ADJUSTMENT OF A SWITCHING STATE OF AN ELECTRIC SWITCHING SYSTEM IN THE FIELD OF GUIDED VEHICLES
    Publication number: 20110260552
    Abstract: A method and a device dynamically control the secure adjustment of a binary switching state of at least one electric switching system built into an automatically functioning apparatus used in the field of guided vehicles, the switching system driving at least one actuator by a driving circuit. The device includes: a control module controlling the state of the electric switching system, and a reading device capable of reading the switching state of the electric switching system and of transmitting a control signal related to the read switching state to a monitoring module. The device is characterized in that the reading device is provided downstream from the electric switching system and is coupled to the driving circuit of the actuator, thereby providing the automatically functioning apparatus with enhanced reliability and maintainability.

  • Device for despatching a secure output command
    Patent number: 7550868
    Abstract: The invention aims to provide a compact device for despatching a command. For this purpose, the invention proposes a novel type of output stage. A secure verification device of the despatching of a binary command signal from at least one conductor has an input terminal and an output terminal. Means of insertion despatch a verification message on said conductor. At least one optical coupler has an emission diode coupled to the conductor so as to copy the verification message when the binary signal is in a first state and not to copy it when it is in a second state different from the first state.
