The invention concerns a human-machine dialog system () comprising:

Human-machine dialog system

A device for detecting and signalling a change of state of a push-button, for example of emergency stop type. The device is in a form of an attachment that can be removed from the push-button and includes: an electrical energy generator housed in a casing of the device and configured to cooperate with a control head of the push-button to convert mechanical energy into electrical energy; and a wireless transmitter to send a message to a remote receiver, the wireless transmitter being housed in the casing and electrically connected to the electrical energy generator.

Device for detecting and signaling a change in the state of a push button

A wireless switching device with an actuating member that can move along a main axis between an idle position and a working position, a spring stressed by force by the actuating member in a direction substantially parallel to the main axis, a switching assembly that can include a plunger arranged to be actuated by the actuating member and a wireless transmitter module provided with an antenna for sending a message to a receiver module in the event of an action on the plunger. The antenna can be arranged prominently on the switching assembly in a direction substantially parallel to the main axis and the spring of helical type being arranged coaxially to the antenna.

Wireless switching device

Photoreceptor circuit switchable between operating modes

Optical detector capable of operating in proximity mode or in proximity with background elimination mode, including an emission system and a reception system having hardware and software detection and configuration means capable of recognizing the appropriate mode by measuring the distance of the background, comparing a reception signal with at least one threshold, and automatically switching the reception system into proximity mode or proximity with background elimination mode depending on the result of the comparison.

Self-configurable optical proximity detector

Method for selecting the operation of an optical detector and multimode optical detector

A bichromatic optical cell fitted with two emitters capable respectively of generating a first beam E and a second beam E of different wavelengths &lgr;1, &lgr;2, and a receiver arranged in a manner to receive, at a fixed or a variable angle of incidence, a beam reflected or able to be influenced by an object, coming from one or other of the emitters. Means of polarizing the first beam E are provided and the cell is fitted with means S of selecting a mode of operation M of the polarized reflex type or a second mode of operation M of the proximity type. The selection means S activate one or other of the emitters depending on the mode selected and block one or other of the output channels of the receiver and/or configure one active optical receiving area of the receiver.

Bichromatic optical cell

Photoelectric cell with means of configuring the operating mode. The cell has several optosensitive zones D capable of outputting magnitudes that are activated or processed in different manners, by configuration and/or processing means The cell may thus be used in reflex mode, proximity mode or proximity with background elimination mode. Amplifying parts are provided at the side of the optosensitive zones to amplify electrical magnitudes before routing them to the microcontroller in the processing circuit

Configurable photoelectric cell

A photoelectric cell which detects a distance of an object, including: a first detection component configured to produce a first current which is a function of the distance of the object; a second detection component configured to produce a second current which is a function of the distance of the object; and, a processing circuit configured to shape a first voltage signal and a second voltage signal that correspond to the first current and second current, respectively. The processing circuit includes a main comparator configured to determine whether the distance of the object is greater or less than a detection range of said photoelectric cell by comparing the first voltage signal and the second voltage signal and to output a switching signal indicative of whether the distance of the object is greater or less than the detection range, and, a locking comparator configured to maintain the switching signal in an inactive state when the first voltage signal is less than a set-point voltage which corresponds to a detection distance greater than the detection range.

Photoelectric cell with lockable differential processing

Photoelectric detector fitted with an optical unit having lenses focused along optical axes of transmitting and receiving components 15, 16 and with an electronic circuit 14 on one edge of which are fixed the components. A reflection head 30 is fixed in sealed manner to body 10 of the detector, said head comprising a prism preferably with total reflection 32 inserted into hood 31 with an air space maintained between reflection surface 32a of the prism and front surface 31a of the hood.
