【Antiinflamatorio】para Tratar el Dolor Muscular - Calmatel.. In some of these embodiments of the invention, the first part, due to its oscillating movement, repetitively interacts with the second generator module and transfers momentum to the second generator module, which thereby continues to oscillate, the frequency of its oscillation depending on a plurality of factors, including dampening due to the generation of electric power, the characteristics of the biasing means, the stiffness of the connecting members, the mass of the second generator module, etc. The pole 1 comprises a relatively rigid part 1 1 , which can be substantially hollow and made of lightweight materials such as, for example, carbon fibre, fibreglass, polyester resin, epoxy resin, basalt fibres, balsa wood, aluminium and/or titanium, etc. By choosing the size and strength of the magnets, the number of magnets and the number of rows of magnets in the vertical direction, as well as the position of the magnets, an interaction between the magnets associated to the first part and the magnets associated to the second part can be set, which serves for the natural frequency of the first part to vary in the most aligned manner possible with the frequency of appearance of the vortices, which in turn varies according to the relative velocity between the fluid (for example, air) and the first part.

Figure 4 shows how the magnets are mounted on a total of five rows, of which the four top rows contribute to the electrical power generation owing to their interaction with the coils 50, while both the four top rows and the bottom row contribute to the auto-tuning of the generator to wind speed. WO-2014/135551 -A1 describes how this can be achieved by actively acting on the piezoelectric material that is part of the structure of the pole.

It also explains how the natural frequency of oscillation of the pole can be modified by applying a voltage to a piezoelectric material that surrounds an elastic core of the pole. This choice of triggering can help to make sure that, for example, a plurality of magnets (“displacing magnets”) attached to the first part are appropriately positioned in relation to corresponding magnets (“displaced magnets”) on the second generator module, so as to provide for appropriate triggering, irrespective of the orientation of the plane in which the first part is oscillating. In other embodiments of the invention, for example, when there is one very predominant direction of movement of the fluid, the pole may have another type of cross section, but the circular cross section can often be the most appropriate one. In some embodiments of the invention, said at least one first magnet comprises a plurality of first magnets arranged at different heights above a base of the generator and said at least one second magnet comprises a plurality of second magnets arranged at different heights above a base of the generator.

Figures 7 and 8 show two sets of magnets associated to the pole, according to a possible embodiment of the invention. In some embodiments of the invention, the system for generating a magnetic field comprises at least one first magnet (for example, one or more annular magnets, or a plurality of magnets which are arranged at two or more points, preferably diametrically opposed, of the circumference of the first part, for example, forming continuous or discontinuous rings at one or more heights of the first part) associated to (for example, attached to) the first part and at least one second magnet (for example, one or several annular magnets, or a plurality of magnets which are arranged in correspondence with two or more points, preferably diametrically opposed, of the circumference of the second part, for example, forming continuous or discontinuous rings, at one or more heights of the second part) associated to (for example, attached to) the second part.

The generator also comprises a subsystem of magnets (comprising at least one magnet) and at least one coil and is configured such that the oscillatory movement of the first part produces a relative displacement between the subsystem of magnets and said at least one coil, such that an electromotive force is generated in said at least one coil. In some embodiments of the invention, the generator is arranged so that as a result of the oscillating movement of the first part, an oscillating movement of the second generator module is produced, said oscillating movement being in a direction parallel with the longitudinal axis of the first part and having a frequency higher than the frequency of the oscillating movement of the first part.

In some embodiments of the invention, the second generator module can be arranged to be repetitively triggered by the first part during said oscillating movement of the first part, by magnetic interaction between the first part and the second generator module. Embodiments featuring magnetic interaction can comprise a plurality of magnets (which can be referred to as displacing magnets) arranged, for example symmetrically, around the longitudinal axis of the first part so as to be displaced by the first part, and corresponding magnets (which can be referred to as displaced magnets) attached to the second generator module.

In many embodiments of the invention, the first part is oscillating at a relatively low frequency, and it can be desirable to produce the displacement between magnet(s) and coil(s) at a higher frequency, to enhance efficient production of electric power. Nonetheless, given that it is indicated that the pole itself is made up of a plurality of elements with high electromechanical coupling, it is understood that it is the swaying of the pole that deforms the elements thereby generating a power differential between the surfaces of the affected elements. Given that the current generated depends on the variations in the magnetic field to which the coil is subjected, this high frequency variation in the magnetic field is beneficial for the generation of current. In some cases, the high speed of the blades may also be a problem, since they may impact bird life.
