Abstract: This timepiece includes a movement with a diameter of less than 40 mm which comprises a barrel (1) for the housing of a mainspring and of which the diameter is less than the radius of said movement. The barrel (1) comprises a cylindrical lateral wall (2), surrounded by a tooth gear (3), of which each edge (21, 21?) is closed by a disk (4, 4?) traversed axially by an opening (5, 5?) for pivoting of a barrel arbor (7). The height of the housing is between 85% and 97% of the total height of the periphery of the barrel (1).

Abstract: An escapement for a mechanical watch comprising: an escapement wheel (10) kinematically connected to a power source, a roller (14) mounted on a balance (16) including, on two different levels, a pin (23) and an impulse pallet (24) co-operating with said wheel (10); a limiting member (26) performing a periodic movement during which it co-operates with the pin (23) to limit the travel of said roller (14); a control member (30) provided with a rest lift (32) performing, from a stable position wherein said wheel (10) is pressed on the rest lift (23), a periodic movement during which the wheel is released and provides an impulse to the impulse pallet (24). The periods of the limiting member (26) and of the control member (30) correspond, respectively, to an alternation and an oscillation of the balance.

Abstract: The invention concerns a timepiece with mainspring of the so-called fly tourbillon type, the tourbillon having a balance bridge (2) forming a cage with a collet (1) and a single protruding ball bearing (5) supporting said so-called fly tourbillon assembly. Said so-called fly tourbillon assembly is visible on the dial side (15) and is designed as an independent tourbillon module. Said tourbillon module is separable from the clockwork (13) by being detached on the rear side of the clockwork (13) and by being removed on that same side.

Abstract: A mechanism for setting and winding of a clockwork, with a winding button spindle, rotatable around its arbor and displaceable in the axial direction, and with a first gear arranged at a distance from the winding button spindle, rotatable around its arbor and displaceable in the direction of its arbor. The rotational movement of this first gear is operatively connected to the rotational movement of the winding button spindle via at least one additional gear. The axial displaceability of the first gear is operatively connected to the axial displaceability of the winding spindle via a first connection device, so that the first gear can be engaged in the axial direction with additional clockwork parts by axial displacement of the winding spindle.

Abstract: The invention relates to a method for transmitting digitized moving images (image data stream) from a transmitter to a receiver. The image data stream that is subdivided into priority classes is transmitted by means of a predetermined protocol to the receiver with the aid of an adaptation layer located at the transmitter. At an adaptation layer of the receiver, transmission errors are determined, subjected to an error processing and fed to an image decoder.
