A test device for a detector for detecting gas or a gas/particle mixture, includes a joining means for joining the test device to the detector; a container configured so as to receive a gas or a test gas/particle mixture; a diffusion means associated with the container and designed to diffuse the gas or the test gas/particle mixture in the detector; an energy source; and a radio apparatus able to manage local radio communication in order to remotely trigger the diffusion of the gas or of the test gas/particle mixture in the diffusion means from a control means. A test system comprising at least one test device, at least one radio gateway, a control network comprising a control unit able to remotely control the test device and at least one communication link between the control unit and the radio gateway, said gateway being able to connect the radio apparatus and the control network.

The present disclosure concerns a smoke detector () including: a detection chamber, a baffle system surrounding the chamber enabling to isolate the chamber from outer light and enabling air to flow from the outside to the inside of the chamber, and a mechanical actuator capable of cleaning, in case of an obstruction, intervals between the elements.

The bottle has a neck sealed by a stopper. The safeguarding device () comprises a first and a second part (), the first part () being adapted to be integrated in the stopper () and the two parts () being joined in translation while allowing a limited relative movement of one part with respect to the other when a traction force is applied to the safeguarding device () in order to remove said stopper () from the neck. According to the invention, the safeguarding device comprises an electrical component () disposed so that at least one electrical characteristic of said component is modified during the relative movement of the two parts ().

A device for recognizing distance in real time includes first, second, and cameras. The third camera arranged nearer the first camera than the second camera. The first, second and third cameras acquire simultaneously first, second and third images, respectively, and an electronic circuit of the device estimates the distance of an object as a function of a stereoscopic correspondence established between first and second elements representative of the object. The first and second elements belong to the first and second images, respectively. The stereoscopic correspondence is established by a relationship between the first elements and corresponding third elements belonging to the third image.

Prosthetic knee joint includes: proximal part mobile in rotation around first axis between extended position and flexion position of prosthetic knee joint; the proximal part being mobile in first direction of rotation from extended position to flexion position, at least one part that is fixed when proximal part is moved in first direction of rotation; link part, arranged to connect the proximal part and part, and presenting contact surface with part; the link part and part being arranged so, when proximal part is moved in first direction of rotation, link part slides on contact surface being subjected to first friction force, when proximal part is moved in second direction of rotation, the link part slides on contact surface being subjected to second friction force strictly lower than first friction force.
