Abstract:
A portable object includes a near-field communication device. The communication device includes an electronic chip provided with two terminals connected to an electrical circuit including an antenna and a filter. The communication device is provided to receive and transmit at a defined frequency corresponding to the resonance frequency of the electrical circuit. The portable object includes a control element which is able to be displaced between two predefined positions, i.e. an active position in which the communication device is activated and a passive position in which the communication device is deactivated. The electrical circuit includes, furthermore, a bypass branch provided with a mechanical switch which is able to switch between an open state and a closed state in response to a displacement of the control element from one to the other of its predefined positions causing a modification in the resonance frequency of the electrical circuit.
Abstract:
An applique intended to be affixed to a timepiece dial including at least one foot portion having a first end attached to the applique and a second, free end, the foot portion being arranged to be capable of insertion into a hole provided in the dial. The foot portion includes at least one aperture opening towards the exterior and forming a housing arranged to receive anchor for anchoring the foot portion to the dial, once the foot portion is inserted into the hole in the dial.
Abstract:
The invention relates to a process for the production of a part provided with an external element comprising the following steps: provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit a metal layer onto the upper surface of the substrate by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layer dissolve the insulating layer cover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assembly separate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element with a shape corresponding to the imprint of the pattern.
Abstract:
A method of manufacturing a ceramic element for a timepiece is provided, including forming a body made of oxide-based ceramic; exposing at least one portion of the external surface of the body to a reduction reaction, to remove oxygen atoms to a predetermined depth in order to make the at least one portion electrically conductive; depositing a metallic material starting from the at least one electrically conductive portion; and machining the body and/or the metallic material in order to provide the element with an aesthetic finish.
Abstract:
A method for depositing a decorative and/or functional layer on at least a portion of a surface of a finished or semi-finished article made of a non-conductive ceramic material, this deposition method includes the following operations: subjecting the at least a portion of the surface of the article to a carburising or nitriding treatment during which carbon, respectively nitrogen atoms, diffuse in the at least a portion of the surface of the article, then depositing, by galvanic growth of a metallic material, the decorative and/or functional layer on at least a portion of the surface of the article which has undergone the carburising or nitriding treatment.
Abstract:
A method of fabricating a decoration provided with at least one attachment includes forming an envelope of material, the envelope including an external surface and an internal surface, and the external surface including a visible embossed part of the decoration, forming the at least one attachment, and fastening the at least one attachment directly and permanently against the internal surface of the envelope of the decoration.
Abstract:
A safety valve for a watch including a head that is movably mounted on a tube and able to move between an open position and a closed position, the tube including in its internal volume a first spring and wherein the tube is provided on an external face with a cam surface allowing a manual movement and an automatic movement of the head into its open position, after the first spring, the tube includes a second spring having a higher stiffness than that of the first spring.
Abstract:
A process for producing a part provided with an external element includes: providing an electrically conductive substrate having an upper surface and a raised pattern with a crest on the upper surface; depositing an electrically insulating layer onto the upper surface around the pattern to a thickness less than or equal to the distance between the crest and the upper surface; depositing a metal layer onto the crest by galvanic growth so that the metal layer partly rests on the insulating layer; dissolving the insulating layer; covering an assembly including the substrate and the metal layer with a mass of a base material of the part to form an imprint; separating the mass and the metal layer from the substrate, the mass then exhibiting an external element formed by a recess, the shape of which corresponds to the imprint and the base of which interfaces with the metal layer.
Abstract:
A fixing device is for attaching a band to a watch case by a connecting link. The watch case includes a case middle, at least one pair of lugs, and a case back. The connecting link includes a passage accepting fixing structure of attachment to the watch case. The fixing structure is incorporated into the connecting link and includes an elastic return separating two pivots mounted with the ability to move inside the passage, and each capable of moving between a compressed position and a rest position in which the pivots are designed to rest in a hole formed in each lug of the watch case.
