Abstract: A device for measuring force comprising, on the one hand, an upper rigid element (1) and a lower rigid element (2) linked by an elastic body (8), and on the other hand a capacitive sensor independent of the elastic body. The elastic body is made out of a single piece of material by machining a hollow cylinder. The capacitive sensor comprises a plurality of flat electrodes (6, 7) laid out so that different combinations of electrodes enable all 6 degrees of freedom to be measured.

Abstract: Driving device especially for a timepiece, constituted by a stepping motor the stator of which comprises a coil having a single winding and the rotor of which is constituted of a permanent magnet and of a control electronic circuit able to deliver pulses of current to the motor. The motor includes precise positioning magnets for its rotor which are active in the absence of the pulses. The electronic control circuit is arranged in such a way that the pulses are delivered in pairs, with opposed polarities in each pair, the order of succession of the polarities in a pair determining the sense of rotation of the rotor.
