  • Patent number: 9810964
    Abstract: An electro-optic modulator includes a waveguide of a nonlinear optical material and an electrode line for generating an electrical field in a modulating region of the waveguide when a voltage is applied to the electrode line, thereby modulating light passing through the waveguide. Therein, the forward electro-optic response of the modulating region is the same as the backward electro-optic response; and the electro-optic response has a band-pass or a low-pass characteristic. A distance measuring device includes a light source emitting light, and such an electro-optic modulator arranged such that the emitted light passes through the electro-optic modulator in a first direction before being emitted from the distance measuring device, and after being reflected from a target passes through the electro-optic modulator in a second direction which is opposite to the first direction.

  • Patent number: 9405007
    Abstract: A distance measuring device includes a light source emitting light, and an integrated electro-optic modulator arranged such that the emitted light passes through an optical waveguide of the electro-optic modulator in a first direction before being emitted from the distance measuring device, and after being reflected from a target passes through the electro-optic modulator in a second direction which is opposite to the first direction. The forward electro-optic response of a modulating region of the electro-optic modulator is the same as the backward electro-optic response, and a center of gravity of the modulation is independent of modulation frequency.

  • Publication number: 20080309202
    Abstract: The electronic component includes at least one resonator element arranged in a housing of a case. The case includes a main part with a base and at least one lateral wall of annular shape, and a cover fixed onto the main part to hermetically seal the housing of the case. One portion of the cover is transparent to a determined wavelength of a light beam to allow the resonator element to be optically adjusted once the case is sealed. The cover is fixed onto a rim of the lateral wall of the main part, which is preferably made of a ceramic material, such that one part of the rim preferably surrounds the entire lateral surface of the cover to ensure protection of the electronic component against lateral shocks.

  • Publication number: 20060049722
    Abstract: The invention concerns a piezoelectric resonator (10), intended to be packaged in a case, including a base (12) formed of a first fixing zone (121), a second central mechanical uncoupling zone (122) and a third zone (123) opposite to the first fixing zone. At least two vibrating arms (13a, 13b) extend from said third zone, on each of which at least one groove (141a-144a, 141b-144b) is formed on at least one of the top or bottom faces of the arms. The resonator is characterised in that the base is provided with a hole (15) through the second central mechanical uncoupling zone.

  • Publication number: 20030067248
    Abstract: The resonator according to the invention, which is intended to be mounted in a case, includes a tuning fork shaped part (42) with two parallel arms (44, 46) connected to each other by a base (48) and carrying electrodes (52, 54) to make them vibrate, these electrodes being connected to connection pads (60, 62) intended to be electrically connected to the exterior of the case. In accordance with the invention, the resonator (40) also includes a central arm (50) attached to the base (48) and located between the arms (44, 46) of the tuning fork shaped part (42), substantially equidistant from them, this central arm (50) having a greater mass than that of the arms of the tuning fork shaped part and the connection pads (60, 62) are carried by this central arm.

  • Publication number: 20010004125
    Abstract: Encapsulated piezoelectric resonator including on the one hand a central plate (5) made of a piezoelectric material cut to form a frame (6) and a central resonant element (9) connected to said frame (6), the top and bottom faces having a metal coating, on the other hand bottom (11) and top (16) covers, each being formed by a spacing frame (12, 17) made of metal or a metal alloy and a closing plate (14, 19), characterized in that at least one of the elements (12, 14, 17, 19) forming the covers (11, 16) is electrically connected to the frame (6) of the central plate (5) and has an extension (10, 13, 18, 20) bent into a Z shape to bring its distal portion (10a, 13a, 18a, 20a) in line with a covering plate (14, 19) and to form electrical and mechanical connection means situated in a same plane.

  • Patent number: 6080250
    Abstract: A device for preparing and applying labels and a method of operating said device is provided. The device includes three parts: a roller transport track, a label dispenser and a label manipulator. The latter can pick up a label deposited by the label dispenser on the roller transport track and stick it at a predetermined point onto an object arranged in any desired way in a three-dimensional space.
