Abstract: Disclosed are embodiments of a rotary-wing drone that includes a drone body, linking arms that extend from the drone body with a propulsion unit located on a distal end of the linking arms, and at least two drone supports extending from the drone body. The drone supports may include a lifting means so that the drone supports are able to be lifted when the drone flies, where the drone supports come into alignment with the linking arms. The drone supports may form the leading edge of the rear linking arms and/or the trailing edge of the front linking arms of the drone.

Abstract: This headset has two earphones adapted to be introduced inside or near to the auditory canal of the user. The earphones are connected by a connection element that has a central band resting on the top of the headset user's head, and two lateral branches extending the band. Each of the bands has, at a proximal end, an articulated connection with the central band; at a distal end, a deformable connection with the respective earphone; and, in a median region, a case that houses electric or electronic components. An internal side of the case, which is directed towards the user's head, has a bearing face that is adapted to come into contact with a temporal region of the headset user.

Abstract: The drone comprises a body and a plurality of propulsion units, each provided with a propeller driven by a respective motor, the different motors being able to be controlled in a differentiated manner so as to pilot the drone in attitude and speed and with production of a lifting force. The accessory has a shaft that is removably fastened to the drone body in a transverse orientation with respect to the main direction of progression of the drone, and at a point located in alignment with the center of gravity of the drone and above that center of gravity. The accessory has two ring elements that are mounted freely in rotation, independently of each other, at the ends of the shaft and symmetrically with respect to the drone body. The density of these ring elements with respect to water is lower than the unit, and their diameter is higher than the overall size of the drone.

Abstract: The fast fixing system comprises a link part (24) integral with the accessory (22), and a support face (26) formed on the drone body (12). The link part is mobile in rotation (28) with respect to the frame between a free position allowing the placing or the removal of the accessory, and a locked position in which the link part is immobilized in rotation and in translation on the frame, so as to form with the latter an integral unit. Means are provided, which define the locked position by a rotation stop of the link part with respect to the frame, means for axial translation blocking of the link part with respect to the frame when the link part is in the locked position, and means for elastic fastening of the link part to the frame once the locked position reached.

Abstract: The device (10) comprises a casing (12) accommodating a microphone (14), a sound reproduction transducer (16), a plurality of control buttons (18, 20, 22, 24), a printed board carrying electronic circuits, a power battery, as well as, possibly, operation indicators (26, 28), an external connector and a near-field communication antenna. The casing is in the form of an elongated band bended on itself in such a manner to form a clamp having laterally a U-shaped profile, a first branch (32) carrying the transducer and a second branch (34) carrying the microphone. The bended band has in the central region a transverse discontinuity (36) mechanically separating the two branches and acoustically decoupling the transducer and the microphone from each other.

Abstract: The appliance comprises a casing, a removable front plate, an electrical connector, and mechanical means for assembling the front plate on the casing and for fastening it thereto. The mechanical means comprise, at a first end, means that form a separable hinge comprising at least one pair of respective magnetic elements such as permanent magnets disposed in the region of the connector and facing one another on the casing and the front plate, and the opposite end, means for locking the front plate to the casing. Mechanical coupling of the front plate on the casing at the location of the separable magnetic hinge results solely from the mutual attraction of the facing magnetic elements.
