A projection method of an electronic device, includes detecting the presence of an object within a preset distance range from a projection unit of the electronic device, generating a projection adjusting instruction if an object is detected within the preset distance range from the projection unit, and adjusting a projection display of the projection unit in response to the projection adjusting instruction.

Watch with a time setting mechanism with an uncouplable motion work lever, with a striking mechanism having a governor, including at least one control piece set in motion by a movement or on user command, and a governor mechanism arranged to regulate to a substantially constant value the rotational speed of a strike function actuator, this striking mechanism including, for at least one control piece, a governor trigger piece arranged, according to the angular position of this control piece, to operate a governor stop jumper able to block or allow the rotation of this governor mechanism, and, by means of an articulated connection, to isolate the motion work lever in an uncoupling position or place it in a coupling position.

An acoustic timepiece display mechanism includes a chronograph repeater for the acoustic display, by a striking mechanism, of a duration measured by a chronograph mechanism. The striking mechanism includes a winding lever for driving a rack to move a striking unit including a rack pinion integral with a striking ratchet, to move a striking rack to read the magnitude concerned and to release a corresponding strike function. The acoustic display mechanism includes, between a control mechanism included in the chronograph mechanism and the winding lever, a safety mechanism arranged, depending on the position of the strike wheel set, to allow or prevent travel of an operating lever of the control mechanism of the chronograph mechanism, which operating lever is arranged to be pivoted under the action of a chronograph start pusher.

Timepiece with a movement driving an output wheel set, a passing strike or minute repeater mechanism, including a strike drive wheel set including a release ratchet with which cooperates a click for execution of a strike function, a strike uncoupling lever for moving any click away from the strike wheel set, including a first lever carrying the click and its spring, the output wheel set activating a second lever, the pivoting of which causes the first lever to pivot, the striking mechanism includes a torque smoothing jumper, which is returned by a first spring into abutment on the output wheel set, in order to use, when the second lever is not in mesh with the output wheel set, an equivalent torque to that which it uses when meshed with this output wheel set.

A repeater mechanism includes: an hour part, which is mobile between a resting position and a reading position; an hour spring that returns the hour part towards its reading position; a chain that is hooked to the hour part; a barrel that includes a shaft, a drum, a spring, a pulley that is mobile in rotation relative to the shaft and on which the chain is hooked, and also a ratchet that is integral in rotation with the barrel shaft and coupled to the pulley as long as the hour part exerts a traction force on the chain, and uncoupled from the pulley as soon as this traction force is cancelled out; and a pulley spring that is interposed between the ratchet and the pulley.
