    摘要: A display device for a timepiece representing the lunar libration phenomenon thanks to at least one Moon disk, to at least one aperture and to at least one drive organ. The at least one Moon disk includes a set of Moon phase representations including at least three Moon phases with a first surface, a second surface and/or a delimitation configured to delimit this first surface and this second surface. The at least one aperture being configured to reveal this set of Moon phase representations and this at least one drive organ is configured to move this at least one Moon disk so as to represent the lunar libration phenomenon.

    摘要: A method for detecting the presence and/or determine a position of an object on a measurement surface of an electronic device. The process includes: providing oscillating signal(s) at input points which are different and spaced from the array of electrodes in a detection area of the measurement surface; receiving oscillating signal(s) having passed through the array, which defines a transfer function of the signals, in output point(s) which are different and spaced from the array of electrodes in a detection area of the measurement surface; measuring a coupling or an attenuation induced by the presence on one or more oscillating signals passing through the array of electrodes of an object placed on the measurement surface in order to determine the position of the object in the detection area of the measurement surface depending on the modification of the transfer function of the array of electrodes.

    摘要: A method for determining an error in the angular position measurement of a timepiece motor having one or more phases, including: detecting (3) each instant (14) when the value of one of the back electromotive forces is zero, storing (4) a time corresponding to each detected instant, measuring (5) several time intervals between two instants (14) detected in the same revolution of the motor, comparing (6) the measured time intervals to reference time intervals to deduce the reference intervals to which they correspond, and determining (7) an angular position measurement error if the measured intervals do not correspond to the expected reference intervals. The invention also relates to a method for correcting the angular position measurement. Also, a determination and correction system for implementing the methods and a timepiece including such a system.
