This invention relates to a deterministic field bus and a process for management of this bus enabling communication of messages between several subscriber stations each comprising at least one controller that generates and decodes the communication protocol, in which an exchange principle is used such that only one subscriber station is activated at any one time, with the others being passive.

Deterministic field bus and process for managing same such that when transmissions from one subscriber station are enabled transmissions from other subscriber stations are disabled

This invention relates to a system for controlling several actuators (Al, . . . , Anr), comprising at least two computers (L, L, . . . , Lk) and at least two means (C, C, . . . , Cn) of controlling at least one actuator, each control module being capable of controlling at least one actuator through at least one first connection () and being capable of receiving information about this at least one actuator through at least one second connection (), in which each control module is connected to at least two computers through at least two first communication buses ().

Control system and process for several actuators

A light signaling device related to the operating state of a system has at least one light and circuits of detection of a failure of this or these lights, in which each light comprises m branches in parallel each composed of n light emitting diodes in series, and a branch selector; where m and n are integers such that m&#x2267;2 and n&#x2267;1. This invention also relates to a process for management of such device.

Light signaling device related to the operating state of a system

This invention relates to a process for management of a light signaling device related to the operating state of a system comprising several lights each comprising several branches of several light elements, that includes a step for dynamic management of redundancy if a branch of a light should fail. This invention also relates to a device making use of this process.
