- regulator 2 the oscillator which serves for maintenance and frequency regulation of the other maintained system, which remains referred to as “the resonator” 1.
- T is the kinetic energy and V the potential energy and inertia / (t), the stiffness k (t) and the rest position x 0 (t) of said resonator are a periodic function of time, x is the generalized coordinate of the resonator.
- the equation of the forced and damped parametric resonator is obtained by the Lagrange equation for the Lagrangian L by adding a forcing f (t) and a Langevin force taking into account the dissipative mechanisms:
- the function f (t) takes the value 0 in the case of a non-forced oscillator.
- This function f (t) can, again, be a periodic function, or be representative of a Dirac type pulse.

- the maintenance oscillator or regulator in addition to the modulation of the parametric terms, also introduces a non-parametric maintenance term f (t), whose amplitude is negligible once the parametric regime is reached [W]. . B. Case, The pumping of a swing from the standing position, Am. J. Phys. 64, 215 (1996)].

- These secondary spiral balances 260 are advantageously replaced by systems without axes, that is to say, flexible guidance, this all the more easily as the amplitude of their oscillation is not necessarily high. In this case, only the inertia of the main balance spring is modified. Depending on the angular position of the unbalance of the small balance-springs, it is thus possible to create a system whose center of gravity is modulated.
- Such a modulation of the position of the center of gravity is preferably a dynamic modulation, acting on one or more of the components of the resonator 1.
- Inertia modulation is achievable by shape modification, by mass change, or by changing the center of gravity of the resonator relative to its center of rotation, for example with the use of a flexible balance. It is also possible to use on-board resonators, with an asymmetry with an adequate phase ratio, as can be seen in FIG. 7, where the imbalances are either in phase or alternating anti-phase.
- this periodic movement imposes a periodic modulation of the resonance frequency of the resonator mechanism 1, by imposing a modulation of the rigidity of an elastic return means that comprises the resonator mechanism 1 or a modulation of a return exerted by a magnetic or electrostatic or electromagnetic field within the resonator mechanism 1. More particularly, in this second variant, the periodic movement imposes a periodic modulation of the resonance frequency of the resonator mechanism 1, by imposing a modulation of the active length of a spring that includes the oscillator mechanism 1 (as visible in FIGS. 1 and 12), or a modulation of the section of a spring that comprises the oscillator mechanism 1 (as visible in FIGS.

- the internal losses can be modified without modifying the rigidity: two springs are substituted for a single spring of equivalent overall stiffness, the internal losses are then greater; it is possible in particular to put in series, or in parallel as the case may be, two springs, one of which may be pre-constrained.
- Another way to change losses while keeping the same rigidity is to use, on a spring, or a thermal compensation by doping silicon, or a thermo-elastic effect with a heat transfer between two different parts of the coil of a spring.
- the periodic movement imposes a periodic modulation of the quality factor of the resonator mechanism 1, modulating the mechanical friction within the resonator mechanism 1, with an effect similar to a virtual increase in gravity.

- the periodic movement imposes a periodic modulation of the rest point of the resonator mechanism 1, by modulating the equilibrium between the restoring forces acting on the resonator mechanism 1 generated by means mechanical elastic return and / or magnetic return means and / or electrostatic return means.
- the simplest is to subject the resonator to several recall forces of different origins, of which it is sufficient to modulate at least one in time, intensity and / or direction. These forces are not necessarily all of the same nature, some may be mechanical (springs) and others related to the application of a field.
- a particular example is the application to a balance spring 3 equipped with two spirals, the modulation of position of only one of the pitons is enough to modulate the balance.
- a twist of a spiral spring is a good way to change the balance of forces applied to the resonator 1, and thus to modulate their balance.
- we can apply the six degrees of freedom to the peak the figure representing a particular simplified application, including rotation around the Z axis can be advantageous;
- the modulation of the position of the rest position is combined with a modulation of the rigidity according to the first mode: in fact, often, if the equilibrium of the forces is modified, the overall rigidity.
- the modulation action on the rest point then combines with a modulation action of the stiffness.
- the modulation is carried out on at least one of these elements.

- these fins are held by flexible blades.
- the speed is intermediate the fins are close to the serge, according to Figure 5A.
- an aerodynamic effect causes them to rise (airfoil effect), during the reversal the fins pass on the other side as can be seen in FIG. 5C.
- the inertia is modified with a frequency which is 4 times the natural frequency of the balance-spring resonator.
