The lens element may comprise one or more lenticular lenses or an array of lenses. In some embodiments, individual reflectors may be interspersed between and among the LEDs in an LED array. 3A and the three bar actuator array 34 of FIG. FIG. 11 shows an example of a motion with a variable rate, here a snap back action. Those skilled in the art will appreciate there are many other potential motion regimens that could be given based on application requirements including a regimen where the actuator is moved and held at a set position to hold a fixed position of the lens element relative to the display.

The motion regimen depicted in FIG. FIG. 10 shows an example of a motion with the constant rate in both directions of movement. The driving and PTO arrangement 5 has been placed into the gap 2 a of the two lower halves of the panel 2 and fastened onto the base 1. The driving and PTO arrangement 5 is situated symmetrically in relation to the pivot shaft 3 a of the panel 2 in the direction of the width of the panel 2, and also in the direction of the reciprocating motion of the panel 2. In that kind of an arrangement there are one or more mutually symmetrically placed PTO units 7 at either side of the panel 2 in the direction of the reciprocating motion of the panel 2. Equally, the PTO units 7 can also be placed in many other ways.

The amount of motion or displacement is proportional to the input voltage Vin. The pair of mutually similar circular coupling elements 8 a is fastened to the first end of a pair of the first lever arms 8 b that are pivoted at their second end to the first end of a pair of the second lever arms 8 c that are further pivoted at their second end to the actuating rod 6 a through a joint pin 8 d that is constantly fastened to the actuating rod 6 a. It can be seen that in that case there are three different alternatives to control the energy capturing; either to use the first pair (p1) alone or together with the second pair (p2) or to use all three pairs simultaneously.

It means that in this control variation the smaller piston head 9 s together with the larger piston head 9 g is used in the first cylinder pair, and the smaller piston heads 9 s only are used in the second and third cylinder pairs. Cansancio dolor muscular sueño . 10. One of the two uppermost hydraulic cylinders 7 h has been partially cross-sectioned so that the piston 9, pressure pace 9 a and the hollow cylindrical space 11 between the inner surface of the cylinder 7 h and the outer surface of the first section of the pistons 9 is seen. 6, where lens element 602 is not in contact with display unit 604, but is separated by a gap 610. Electroactive polymer actuator 606 lies beneath display unit 604 and is in contact with housing 608. In principle, the gap between the lens and the display unit may be any distance; however, it should be remembered that the gap will require a change in focal length of the lens element to ensure that it focuses on the display correctly.
They may also be molded into either the lens element 602 or the housing 608. Alternatively, the standoffs may comprise springs or telescoping sections which enable the adjustment of the gap. Also the control of the apparatuses according to prior art has caused problems because the force of waves varies a lot. BACKGROUND According to prior art there are various types of wave energy recovery systems where the arrangements include a base and, for instance, one or more panels pivotally connected to the base to make a reciprocating or oscillating movement about a rotation axis or pivot axis in response to wave forces or tidal forces.
The reciprocating panel 2 oscillates on the base 1 back and forth with the movement of seawater for recovering kinetic energy like wave energy of seawater. However, before the removal of the hydraulic cylinder block 7 a both the free end of the hydraulic cylinder block 7 a and the free end of the guiding cylinder 6 b must be closed and sealed against seawater. Preferably a closing and sealing mechanism 12 is placed between the connecting ends of the guiding cylinders 4 a and 6 b.
However, in order to remove the PTO unit 7 the hydraulic cylinder block 7 a must be separated from the guiding cylinder 6 b. At first the PTO unit 7 is descended onto the base 1 and fastened at its place. And one further advantage is that a part of the energy capturing hydraulic cylinders can be easily switched off without disturbing the operation of the other hydraulic cylinders. FIG. 12 presents in a side view, partially cross-sectioned and in a simplified and diagrammatic way the power-take-off arrangement according to FIG. Dolor externo de rodilla . FIG. 12 shows the sequence of steps for assembly of an embodiment of optical system which comprises artwork as the display.
FIG. 7 provides a side view of the embodiment of the optical system of the present invention shown in FIG. The optical system of the present invention may find use in point-of-purchase displays or general illumination applications. FIELD OF THE INVENTION The present invention relates in general to optical systems and more specifically to lenticular lens systems which enable the viewer to see two or more images in a display, such as an artwork, sequentially by changing the angle of the lenticular lens with respect to the viewer or by changing the position of the lens with respect to the display. The present invention provides an optical system comprising a lens element, a display unit displaced transversely from the lens element, at least one actuator coupled to at least one of the lens element or the display unit and capable of changing position of the lens element relative to the display unit in a lateral direction, and an electronic control system capable of driving the at least one actuator to move in a programmed manner to control positioning of the lens element relative to the display unit.

Such a control system is capable of driving the actuator to move in a programmed manner to control positioning of the lens element relative to the display unit. In FIGS. 5-7 also an energy conversion machinery 7 c of the PTO unit 7 is shown. Such a lighting system 930 is illustrated in FIGS. For example, FIGS. 9A and 9B show actuator 932 acting in a bi-lateral manner to provide left-directed rays 938 and right-directed rays 940. A greater number of phases may be employed to produce a rotating light effect, such as those used on emergency vehicles, or a “wobble” pattern. Depending on the application, a tertiary reflector or reflectors (not shown), which are also stationary relative to the primary reflector, may be employed to assist in redirecting stray rays from the light source. The foregoing examples of the present invention are offered for the purpose of illustration and not limitation.

To vary the diffusion angle, a translucent member is placed between the LED system and the surface. A reflector can be between the light source and the user as well as behind the light source. Alternatively, both the light source as well as the reflector assembly may be driven each by its own actuator to provide more control over the direction and diffusion of the light vector. A flat, small, and lightweight form factor is particularly suitable for point-of-purchase displays and low profile lighting systems. Still further, a multi-phase electroactive polymer actuator may be employed to provide a unique lighting pattern, e.g., a strobe effect, flashing, etc. Dolor de vientre bajo y espalda . The actuator(s) may be moved at different frequencies or with variable rates to provide complex patterns of colors, intensity, focus, and other lighting effects such as a stroboscopic effect. The oscillating movement is then converted for example to electric energy with the help of a power-take-off (PTO) unit equipped with a power-take-off (PTO) machinery comprising a generator or alike.
This function is achieved for instance by a pressure prevailing in the hydraulic circuit 9 b of the PTO unit 7 which pressure is returned the pressure spaces 9 a, or by springs or another appropriate actuator. Thus, for instance, divers are needed to perform the job. In that case there are 26 different alternatives to combine the use of the cylinder pairs and their piston heads for controlling the energy capturing.
