Abstract: A control device includes at least one push-button (3) slideably mounted in a shell (1) in a push-button direction (P) substantially perpendicular to the shell (1), and elastic elements (50) that tend to cause the button (3) to emerge from the shell (1) and retaining elements (4, 30) that limit the travel of the button (3) against the action of the elastic elements (50). The retaining elements include at least one hook (30) of the button (3) of which a nose (300) projects perpendicularly to the push-button direction (P), and a rod (4) running parallel to the shell (1) to form an end stop for the button (3) in collaboration with the nose (300) of the hook (30), the rod (4) being mounted removably in the shell (1).

Abstract: A device (100) for wireless electrical charging, intended to be installed in an automobile has a coil referred to as the “emitter coil” and a circuit for supplying the emitter coil, a first part (101) and a second part (102), at least one of which can move relative to the other between: a closed position of the device, in which the first and second parts are arranged so as to delimit a cavity for receiving a terminal (107); and an open position of the device adapted to allow insertion of the terminal. The second part has on the side of the first part a resilient element (103) including a rigid portion (110) which includes the emitter coil, the rigid portion being adapted to bear, when the device is in the closed position, against the terminal in the reception cavity, and to hold the terminal immobile against the first part.

Abstract: Method and device for communication between an automobile vehicle and payment unit carried by a user in order to pay for an action carried out on the vehicle equipped with wireless communication elements (11) and the payment unit including at least one portable device equipped with wireless communication elements (22) for communicating with the vehicle via a wireless communication (A) and with a central server via a wireless communication (C) and an electronic payment card, the method including: equipping the payment card with wireless communication elements for communicating with the portable device via a wireless communication (B), equipping the payment card with storage elements, performing various steps for mutual recognition between the various elements of the device, and authorizing use of the payment card via authentication data for single use sent by the central server to the portable device then stored in the payment card.

Abstract: A radiofrequency transmitter (1) including two plastic covers (61, 62) arranged one on top of the other, enclosing a printed circuit (5), and having a metal belt (3) inserted between the covers in their joining area, characterized in that an internal portion of the metal belt (3) is fixed in at least one recess (212) created between the two plastic covers (61, 62). A method for assembling a radiofrequency transmitter (1) including a step of assembling the different parts forming the transmitter (1) is also described.

Abstract: A multicontact block includes at least two independent electrical contacts (2-6) of the blister-effect type that are capable of elastic deformation. This multicontact block includes two longitudinal profile elements (11, 12), called stays, to each of which each blister-effect contact (2-6) is connected via an elastic flat section (21, 22) capable of allowing the elastic deformation of the contact, and two transverse profile elements for rigidification (7-10), called cross-ties, running between the stays (11, 12) and interposed between the contacts (2-6). Moreover, support lugs (13-16) are positioned under the profile elements (7, 10) and define a support reference plane for the multicontact block, designed to be intercepted by each contact (2-6) when it is deformed elastically.
