An antenna assembly for a mobile device comprising a printed circuit board and an antenna structure located at a distance from the printed circuit board. The antenna structure is electrically connected to the printed circuit board via at least one elastomeric connector comprising a plurality of conductive filaments and an insulating structure extending between the antenna structure and the printed circuit board.

Antenna assembly for a time-piece

The optical recognition system determines the position and/or movement of an object () on a positioning device (). The positioning device includes means () for driving the object in rotation and/or along a curvilinear or rectilinear path. The optical recognition system includes optical detection means, such as a digital camera (), for detecting the position or orientation of the object, and a data processing station () for data supplied by the detection means. A certain number of different figures or references are distributed over the external surface of the object. The arrangement of each figure on the external surface of the object enables the detection means, associated with the data processing station, to determine the position or orientation of the object on the positioning device. The figures are formed by circular barcodes (), wherein each circular barcode defines a precise position of the object () on the positioning device.

System for optical recognition of the position and movement of an object on a positioning device

The positioning device can position a spherical object. This object is placed and held by gravity on three points of support (P, P', P&#x2033;) of the positioning device. The center of gravity of the object in any position is within the triangle formed by the three points of support. The positioning device includes means for driving the object in rotation. The drive means includes a drive member including wheel whose contact with the external surface of the object forms one of the support points (P) of the positioning device. This drive member can impose a rotation on the object, via the wheel, in all directions. The other two points of support (P&#x2032;, P&#x2033;) are made using two ball and socket joints, wherein the ball is held on an air cushion in a housing of the ball and socket joint.

Device for positioning an object in all directions

The measuring system includes a receiver including at least one fixed receiving antenna for picking up electromagnetic fields generated by a transmitting antenna belonging to an electronic device, and a positioning device on which a support element is placed. The positioning device includes mechanisms for driving the support element in rotation. The measuring system further includes a detection device for detecting position/orientation of the transmitting antenna, and a data processing station. A hollow spherical element houses the electronic device, and is held on the positioning device by gravity on three points, one of which is formed by a drive member, and the two other points are formed using ball and socket joints. Several circular barcodes arranged on the external surface of the spherical element enable the system to determine the position/orientation of the spherical element using the digital camera.
