12, the trajectory of the movement (II) with magnetic repulsion experiences an increase in oscillation frequency compared to the damped simple harmonic movement (I) for large displacements. When the device has no tuning system, its movement can be modeled as damping one of the simple harmonic oscillators (a) (fig. In other words, the function of the magnets 30 and 40 may be to obtain an automatic tuning between the natural oscillation frequency of the rod and the frequency at which eddy currents occur.

Fig. 18 schematically shows how the rod-like members 605 are attached at one end to the ring-shaped frame member 601 of the first generator module and at the other end to the ring-shaped frame member 602 of the second generator module. This trigger selection may help to ensure that, for example, a plurality of magnets (“displacement magnets”) attached to the first portion are properly positioned relative to corresponding magnets (“displacement magnets”) on the second generator module to provide proper triggering regardless of the orientation of the plane in which the first portion oscillates. The rigid top is attached to the base by a flexible bottom so that the rigid top can oscillate relative to the base.

In some embodiments of the invention, the displacement magnets are arranged around or at a distance from the longitudinal axis of the first part to interact with respective ones of the displaced magnets during oscillation of the first part to repeatedly transfer momentum from the first part to the second generator module. In some embodiments of the invention, the flexible connection members have a cross-section having a first width in said axial direction of displacement of the second generator module and a second width in a direction perpendicular to said axial direction, said second width being larger than said first width. In some embodiments of the invention, the second generator module is biased in a first direction by a first biasing means, such as by a first biasing means comprising a magnet and/or a spring, the first direction being parallel to the longitudinal axis of the first portion.

In this way, when the oscillation of the rod 1 occurs, the flexible portion 12 bends to one side and to the other, so that a portion of the magnets 30 mounted on the flexible portion 12 approaches a portion of the magnets 40 mounted on the static structure 2, while on the diametrically opposite side of the flexible portion 12, a portion of the magnets 30 is distant from the magnets 40 of the corresponding portion. Such a tilt has been found useful for introducing a torque which may be used to reduce or eliminate the tendency of the first part to enter a resonant mode different from the resonant mode corresponding to its natural oscillation frequency. In other embodiments of the invention, the rod may have another type of cross-section, for example when there is a very dominant direction of movement of the fluid, but a circular cross-section may generally be the most suitable one.
In other embodiments of the invention, the coil and magnet may be present in both the first and second generator modules, etc. The energy generated by the coil 50 may be suitably regulated and constrained by the power electronics system 60, the power electronics system 60 may comprise, for example, an inverter or the like, and the conduction system 61 may drain the generated power. As explained above, there is a small range of wind speeds (locked aerodynamic phenomenon) where the karman vortex based device can maintain its resonance, but this is much less than what is required for a reasonably competitive wind generator. Fig. 4 shows that the flexure 12, which is rod-shaped, supports five rings of magnets 30 and that, coaxially with respect to these rings of magnets 30, there are five rings of magnets 40 mounted on the static structure 2 coaxially with respect to the flexure 12 of the rod.
7 and 8, with one set of magnets disposed above the other and separated by a gap in which a coil 50 may be mounted. In this document, the word “comprise” and variations such as “comprises” and “comprising”, etc., are not to be interpreted as exclusive, that is, they do not exclude the possibility of other elements, steps or the like being included in the description. For example, in the case of a first part in the shape of a bar without a system for adapting to the resonance frequency, the bar does not oscillate when the wind speed is too low. In this embodiment of the invention, the rod 1 has a circular cross-section, so that it does not depend on the direction of the wind, which may vary over time, in terms of its ability to capture the energy of the wind. 605, such as metal or carbon fibre rods or bars, which may be used to maintain the relative position of the first and second generator modules, which are substantially fixed in a plane perpendicular to the longitudinal axis of the first part, thereby preventing contact between the first and second generator modules while allowing sufficient amplitude of movement of the second generator module relative to the first generator module, parallel to said longitudinal axis of the first part.

That is, the first part is caused to be moved by the eddy currents, whereby energy is transferred from the fluid to the first part, which is then transferred to the second generator module, which causes an oscillation, whereby this energy part is converted into electrical energy due to the relative movement between the magnet and the coil. The first part including the relevant elements may have a substantially larger inertia and generally a larger mass than the second generator module, whereby the triggering may cause the second generator module to oscillate at a relatively high frequency compared to the oscillation frequency of the first part; the link between mass and inertia has been discussed above. In some embodiments of the invention, the second generator module is connected to the first generator module by means of a plurality of connecting members arranged to allow the second generator module to move parallel to the longitudinal axis of the first portion and to prevent the second generator module from contacting the first generator module.
The fact that the second generator module may be made to oscillate at a higher frequency than the oscillation frequency of the first portion may be useful for enhancing the efficiency of the conversion of the energy represented by the oscillation of the first portion into electrical energy. In some embodiments of the invention, the first portion has a height of at least 1 meter, for example above 2 meters, 5 meters, 10 meters, 15 meters, 60 meters, 100 meters, or 200 meters.
As the wind speed continues to increase, although the amplitude increases at a decreasing rate, conversely the repulsion force increases very fast (since the increase is preferably inversely proportional to the square of the distance between the first and second portions) enabling the system to store potential energy in the magnet which is converted fully or substantially to kinetic energy (speed) when the first portion passes through the neutral position of zero bending, which enables the natural oscillation frequency of the first portion to be increased. Postura de yoga para dolor de espalda . Thus, when the amplitude of the oscillating movement increases, the magnetic repulsion between the first and second portions increases, and when the amplitude of the oscillating movement decreases, the magnetic repulsion between the first and second portions decreases. In some embodiments of the invention, each connection member is connected to a first generator module at a first connection point and to a second generator module at a second connection point, wherein the connection points or a projection of the connection points on a plane perpendicular to the longitudinal axis of the first part are separated by an angle α in a plane perpendicular to the longitudinal axis of the first part (i.e.
In some embodiments of the invention, the generator is arranged such that during the oscillatory movement of the first part a force is exerted on the second generator module to displace the second generator module parallel to the longitudinal axis of the first part, the force varying during the oscillatory movement of the first part. Fig. 7, 8 and 9 schematically show how magnets mounted on the support 13 discussed above may be arranged at each stage in the shape of a plurality of concentric rings 30, 31 and 32 in some embodiments of the invention. Some embodiments of the invention include both the first and second aspects described above. Fig. 18 is a cross-sectional top view of a portion of the generator of the embodiment of fig. That is, rather than using a member that allows movement by rolling or stretching, the ability of the connecting member to bend to a certain amount allows movement of the second generator module in a direction parallel to the longitudinal axis of the first portion.
In this way, the structure of the generator with magnets 30 and 40 of fig. Furthermore, the generator has a second portion, which may be substantially static, and which at least partially surrounds the first portion, e.g. Causas del dolor de pie . This variation may be used to cause an oscillation of the second generator module parallel to the longitudinal axis of the first part, and the oscillation implies a relative movement between the magnet and the coil, thereby converting kinetic energy into electrical energy. Fig. 4 shows how the magnets are mounted on a total of five rows, the top four contributing to the generation of electricity due to the interaction with the coils 50, and the top four and bottom contributing to the auto-tuning of the generator to the wind speed. The turns of the coil 50 are parallel or nearly parallel to the horizontal plane. 1 and 4 contributes to an automatic increase of the resonant frequency of the rod when the wind speed increases, and vice versa.

During the oscillating movement of the first part 1 comprising the flexure 12, the distance between the shifting magnet 700/701 and the shifted magnet 702/703 will periodically increase and decrease. In some embodiments of the invention, the direction is upward. In some embodiments of the invention, the second direction is downward. The arrangement of fig.
