Abstract
Method of determining a motion of continuous variable velocity for display means, comprising a step of establishing a model of at least one simulated mechanical force and/or torque value from values measured by a sensor, and a second step of solving a newton equation of motion from these simulated mechanical force and/or torque values, wherein the second step allows a simulated velocity to be calculated for the display means.
Claims12
A method of determining a motion for a display member of a timepiece, the method comprising:
- rotating a crown of the timepiece;
- establishing a model for calculating at least one simulated mechanical force and/or torque value from values measured from the rotating crown by a sensor;
- obtaining a physical magnitude from the rotating of the crown;
- inputting the physical magnitude, measured values, and at least one simulated force and/or torque into a Newtonian equation of motion;
- solving the Newtonian equation to calculate a simulated speed for said display member;
- and
- moving the display member at the simulated speed,
- wherein the display member is a movable mechanical component that is viewable on the timepiece.
