  • Patent number: 9174035
    Abstract: An applicator that has an elastic band to snap a microneedle array against skin with a predetermined force and velocity. The microneedle array, which may be pre-loaded with drug(s), is attached to the elastic band such that the band can be secured in place (e.g., wrapped around a person's arm), pulled away from the arm, and released from a suitable distance so that the microneedle array snaps back against the arm with sufficient force to cause an intended amount of penetration of microneedles. Also, a microneedle application device has an elastic band, a microneedle device, and a structure attaching the band to the microneedle device.

  • Patent number: 9093289
    Abstract: A method for assembling a device on two substantially parallel taut threads. The device includes an electronic chip and two substantially parallel grooves open on opposite sides of the device. The distance separating the grooves corresponds to the distance separating the threads. The device presents a penetrating shape along an axis perpendicular to the plane of the grooves, having a base at the level of the grooves and an apex of smaller size than the distance separating the threads. The method includes the steps consisting in placing the apex of the device between the two threads; in moving the device between the two threads resulting in the threads being separated from one another by the penetrating shape of the device; and in continuing movement of the device until the threads penetrate into the grooves reverting to their initial separation distance.

  • Patent number: 6406769
    Abstract: The invention concerns a watch crystal (1) made of hard mineral material, in particular a crystalline material such as corundum, sapphire or spinel, including a non-circular optical lens (4) shaped in the thickness of the material of the crystal. The lens is formed by machining and polishing a recess (5) preferably situated in the lower face (3) of the crystal. Its contour can have reentering angles, and can be for example rectangular. The machining is effected by means of a brush which hits the bottom of the recess with the addition of a polishing medium.

  • Patent number: 6116774
    Abstract: A bonded body uses an adhesive having high water resistance to realize an adhesive-fixed structure having excellent waterproof properties and exhibiting relatively low changes in properties of the adhesive layer over time. The adhesive-fixed body of the present invention can be obtained by bonding and fixing a body and a glass cover as exterior pairs of a watch with an adhesive layer. The adhesive of the invention can be a curable adhesive containing 100 parts by weight of prepolymer resin having polytetramethylene oxide as a main chain and methacryl groups or acryl groups at both ends of the main chain or in side chains, 50 to 300 parts by weight of at least one selected from acrylic monomers or methacrylic monomers comprising isobornyl acrylate, isobornyl methacrylate or a mixture thereof, and a coupling agent.

  • Patent number: 6019860
    Abstract: Method for fixing two elements together, in particular links (1) of a metal wristwatch strap, according to which a metal pin (2) made of a moulding memory alloy with large hysteresis--programmed such that it turns from the martensitic structure to the austenitic structure in a first temperature range which is situated above the service temperature of the elements and whereby its thickness increases, and such that it turns back from the austenitic structure to the martensitic structure in a second temperature range which is situated under the above-mentioned service temperature--is clamped in the martensitic structure in at least one either or not blind hole (3) in at least one of the elements to be linked; the pin (2) is subsequently heated to a temperature higher than the first temperature range, such that the thickness of the pin (2) is increased, whereby the clamping force of the pin (2) in the hole (3) becomes very large; and the pin (2) is finally cooled down to service temperature, characterized in that
