The invention relates to a universal interface (INT) arranged to be positioned between a detector (D) and a monitoring-control unit of equipment and comprising:

Universal interface for detector

A human-machine dialog system including a first part including a data processing unit and an electrical power supply unit, a second part including a number of human-machine dialog members each provided with a human-machine dialog interface, and a fastening support arranged to accommodate each human-machine dialog member in a removable and interchangeable manner, and a communication and power supply bus linking the power supply unit and the processing unit of the first part to each human-machine dialog member.

Human-machine dialog system

A method is provided for monitoring a communication between a transmitting equipment item and a receiving equipment item, the transmitting equipment item transmitting control frames (TC_i) toward the receiving equipment item. The method makes it possible to optimize the frequency of transmission of diagnostic frames (TDx_i), thereby making it possible to avoid saturating the communication link and causing an overconsumption of electrical energy, while guaranteeing a high reliability concerning the state of the communication. The method makes it possible notably to adapt in real time the transmission of the diagnostic frames (TDx_i) to the state of the communication, by taking account of the fact that disturbances prevent the control frames (TC_i) from being correctly transmitted by the transmitting equipment item or received by the receiving equipment item and to adapt the transmission of the diagnostic frames (TDx_i) to the value of the rate of probability of occurrence of a communication failure (&#x3c4;), this rate being recalculated on each transmission of a control frame.

Method for monitoring communication between a transmitter and a receiver

A method for monitoring a communication between a transmitting equipment item and a receiving equipment item, said transmitting equipment item transmitting control frames (TC_i) to the receiving equipment item. The method makes it possible to take account of the fact that the control frames (TC_i) are not necessarily transmitted at fixed frequency and to adapt the transmission of the diagnostic frames (TDx_i) to the frequency of transmission of the control frames. Upon a significant variation of this transmission frequency, if no diagnostic frame has been transmitted between the two control frames, the instant of transmission of the next diagnostic frame will take account of this aspect. The method of the invention makes it possible to optimize the frequency of transmission of the diagnostic frames while guaranteeing a high reliability concerning the state of the communication, in order to avoid saturating the communication link and causing an overconsumption of electrical energy, and to adapt in real time the transmission of the diagnostic frames to the frequency of transmission of the control frames.

The invention relates to a method for monitoring a communication between a transmitter entity and a receiver entity. It consists of the transmission of diagnostic frames D dedicated to the monitoring of the communication. The objective of the monitoring is to ascertain the state of the communication before the next data communication frame C so as to be able to ensure that the latter has the maximum chance of taking place. Accordingly, at least one diagnostic frame D must be transmitted before the probable next transmission of a data communication frame C. The instant of transmission Tdiag[0] of the first diagnostic frame D is determined from the minimum period to be complied with between the transmission of two communication frames C. The instants of transmission Tdiag[i] of the diagnostic frames D which follow the first diagnostic frame transmitted at the instant Tdiag[0] are determined on the basis of an increasing function.

Method for monitoring a communication between a transmitter entity and a receiver entity

An emergency stop device including a body, a control button that is translatably movable along a control axis, at least one set of electric contacts that are normally closed and which include a mobile electric contact and a stationary electric contact, a flexible blade having a first free end and a second free end, and an actuation push member that can be translatably actuated, by the control button, between a rest position and an actuated position, and which is configured to engage with the flexible blade. The flexible blade includes a bearing area for the actuation push member, and the flexible blade is shaped to rigidify the bearing area.

Emergency stop device adaptable for a man-machine dialog system

A man/machine dialogue system including: an RFID read/write station including a data processor; an antenna that is magnetically connected or coupled with the read/write station; and a man/machine dialogue member including a man/machine dialogue interface and an electronic tag. The electronic tag includes an internal memory and a processor and is positioned so as to be supplied with power, via magnetic coupling, by the read/write station and so as to be in contactless communication, via magnetic coupling, with the read/write station.

Man/machine dialogue system

A luminous turning button for an electric circuit, including a handle mounted to pivot about an axis to actuate at least one electric switch unit and that is illuminated by a light source substantially disposed along the axis. The handle includes a cap forming a disk and a gripping tab that protrudes in a diametral plane. The cap is made of translucent or transparent material capable of allowing the light to travel to the outside, the gripping tab being hollow and covering an integrated mechanical base made of opaque material.
