  • Patent number: 10739136
    Abstract: An ascent rate indicator mechanism includes a first wheel set and a pressure sensor. The first wheel set is connected to the pressure sensor driven in rotation by a pressure variation. The mechanism further includes a second wheel set driven by the first wheel set in a single direction of rotation from a start position into a measurement position corresponding to a decrease in pressure, uncoupling and return structure to be actuated at regular intervals to uncouple the second wheel set and to return it to the start position, an ascent rate display mechanism connected to the second wheel set and including an indicator member arranged to occupy, at each regular interval, a display position representative of the decrease in pressure during the interval, and synchronization structure actuated at each regular interval and arranged to maintain the display position of the indicator member during the regular interval.

  • Patent number: 8848488
    Abstract: A timepiece mechanism for a secondary display of a first physical quantity, wherein a push-button activates first mechanism for the coupling/uncoupling of the secondary display to or from a movement including a first display, and a pivoting first physical quantity cannon-pinion heart, wherein the first mechanism controls the coupling/uncoupling to or from the movement. A second push-button controls the zero reset of the secondary display, by uncoupling the first coupling/uncoupling mechanism, and returning the heart-piece to the original position thereof. A second coupling/uncoupling control mechanism includes either a pivoting time zone wheel set including a friction wheel, meshing with the movement, and a time zone wheel which, when the wheel set is in the coupling position, drives a second physical quantity cannon-pinion heart and/or a third physical quantity cannon-pinion heart, the friction wheel and time zone wheel being coaxial and cooperating via friction; or an inter-time zone mechanism.
