Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a human-machine dialog system comprising: a first part (1) including a data processing unit and an electrical power supply unit (11), a second part comprising a number of human-machine dialog members (2) each provided with a human-machine dialog interface (20) and a fastening support (3) arranged to accommodate each human-machine dialog member (2) in a removable and interchangeable manner, a communication and power supply bus (4) linking the power supply unit (11) and the processing unit of the first part (1) to each human-machine dialog member (2), said communication and power supply bus (4) being at least partly arranged in the fastening support (3) to connect each human-machine dialog member (2).

Abstract: A telephone communication system comprising a radiocommunication module (10) and a data encryption/decryption module (28), characterized in that the radiocommunication module (10) comprises a modem interface module (20) which is connected to the radiocommunication module (10) and controls an external modem (33). The encryption/decryption module (28) comprises a microcircuit support reader, an encryption/decryption circuit (29) and a vocoder circuit (30) receiving voice data to be encrypted or decrypted from the communication module (10). The encryption/decryption (29) of data is carried out directly in the encryption/decryption circuit (29) of the encryption/decryption module.
