    Abstract: A display mechanism of a watch including at least one indicator member and a drive member assembly. The indicator member is mounted to rotate about a first axis of rotation and is configured to indicate a time. The indicator member also has a second axis of rotation extending along the indicator member and a rotary element mounted to rotate about the second axis of rotation. The drive assembly includes a first drive member and a second drive member such that the first drive member drives the rotary element when it is moving about the first axis of rotation.

    Abstract: A portable electronic authentication device (10) for providing access to a website or a computer resource or a secure place. The portable electronic device includes a first communication unit (11) and a second communication unit (12) different from the first communication unit. The first communication unit is intended to receive an interrogation signal (SP) from a control device of a control system, which includes the portable electronic device. The second communication unit is intended to transmit a response signal (SL) which includes identification data of the portable electronic device to authenticate the portable electronic device in the control system and allow access to a website or a computer resource or a secured place.

    Abstract: The active lighting device of a bicycle includes a first optical system with a first light source for long-distance illumination, controlled by a control unit, and a second optical system with a second light source for short-distance illumination, controlled by the control unit. It includes a light sensor for determining the light intensity of a location in which the bicycle is situated and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

    Abstract: An antenna (100) for near-field communication including an electrically conducting track (102). This track (102) defines, by the pattern thereof, a primary shape of the antenna and includes an arrangement of primary portions (121) of the same width and of secondary portions (122) of different widths to that of the primary portions (121), such that the arrangement forms a figurative image (123) on the antenna (100).

    Abstract: An active lighting device is placed on a person's wrist to light a path that the person is taking. The device is preferably in the form of a wristwatch. The device includes first light sources, which are controlled by a control unit. The first light sources are placed on a portion of a case. Each first light source activated by the control unit can produce a light beam of different orientation from another first light source activated by the control unit. The device further includes a motion sensor connected to the control unit to determine the wrist movement of the person wearing the device in order to allow the control unit to select certain first light sources to be activated depending on the person's wrist movement in order to light the path to be followed in the same defined forward direction.

    Abstract: A reference oscillator for a transmitter and/or a receiver of electromagnetic signals. The reference oscillator is suitable for generating a modified reference signal alternating ON times and OFF times with a predefined duty cycle from a signal supplied by a reference resonator. The reference oscillator also includes an adjustment circuit suitable for adjusting the duty cycle of the modified reference signal according to at least one adjustment parameter dependent on a rank of at least one harmonic component of the modified reference signal so as to minimize at least one harmonic component of the modified reference signal. A frequency synthesizer and a radio frequency signal receiver can include such a reference oscillator.
