A portable electronic object including a case including at least a first part made of insulating materials, at least one electronic module providing at least one piece of information to a display, and a controller allowing a user to act on the at least one electronic module.

Portable touch electronic object

A system including at least a first command issuing device and at least one second command receiving device, each including a control unit and a short-range radio communication unit, the system configured to use at least a first functional profile allowing execution of a first function, the first profile allowing the first device to generate a first coded message, the first function being executed by the at least one second command receiving device upon receipt of the first coded message by the second device. The system is further configured such that the second command receiving device can execute a second function in response to receipt of the first coded message.

Multi-device system with simplified communication

The smart battery includes an electronic circuit for managing the supply voltage connected to a battery. The electronic circuit includes a battery end-of-life detector, a management unit, an oscillator stage, a DC-DC converter powered on when the supply voltage of the battery is close or equal to a battery end-of-life threshold, and a data or command communication interface. The data or command communication interface is a 1-wire interface which is connected to a positive supply voltage terminal of the smart battery for transmitting a modulated data or command signal through one of the supply voltage terminals. The modulated signal transmitted by the interface may include battery end-of-life information.

A sealed pushbutton for a wristwatch includes a pushbutton head that is movable between a resting position and an active position, a first fixed conductive element, a second movable conductive element, and an elastically deformable capsule. The elastically deformable capsule hermetically covers the first fixed conductor, and an upper surface of the capsule is in physical contact with a lower surface of the pushbutton head and the capsule is locatable in a non-deformed position when the pushbutton head is in its resting position and in a deformed position when the pushbutton head is in its active position. The first and second conductive elements form a capacitive or resistive switch device, and the switch is in open state when the pushbutton head is in its resting position and in closed state when the pushbutton head is in its active position.

Waterproof watch pushbutton

A wristwatch with capacitive touch zones including a case made of a non electrically conductive material, the case including a housing in which a battery is housed and which is closed by an electrically conductive battery cover. The electrically conductive battery cover is mounted on the watch case with interposition of an electrically conductive sealing gasket between the battery cover and the battery.

There is disclosed a method for maintaining the oscillations of a vibrating device and a vibrating device implementing this method. The vibrating device is intended to be fitted to a unit worn close to the body, such as a timepiece, including a case, a moving mass inside this case intended to transmit vibrations thereto, a coil (L) electromagnetically coupled to said moving mass in order to make it vibrate, and an excitation circuit for exciting said coil CL). According to the method disclosed, driving pulses () of alternate polarity and determined duration (T) substantially coinciding with the extrema of the movement induced voltage (U, V) across the terminals (B, B) of said coil (L) are generated.

The watch is provided with a circular row of capacitive keys defined by transparent electrodes (to) arranged on the inner face of the crystal () of the watch and connected to a detection device via a multiplexer. These keys are activated by the person wearing the watch placing a finger () on the crystal facing one of the electrodes. The watch further includes means for detecting the position of at least one of the hands () by means of the same detection device, using the electrodes (to) of the capacitive keys and/or other fixed electrodes ().
