Jump of young woman over green using laptop or tablet gadget while jumping. running girl in motion or movement FIG. 3C illustrates one embodiment of a six bar actuator array 36 comprising six bars 36A, 36B, 36C, 36D, 36E, 36F coupled to a fixed frame 31, where each bar is separated by a divider 37. Each of the bars 34A-F comprises an electrode 32 and an elastomeric dielectric 33. The six bar actuator array 36 amplifies the motion of the sliding surface in comparison to the single bar actuator array 30 of FIG. Individual reflectors/lenses or groups of reflectors/lens may be driven or moved independently of each other to provide multi-faceted directionality to the light rays. The diaphragm may have any number of phases to provide the desired effect. 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. As for light sources, any type may be employed with the subject systems, depending on the desired lighting elect.

Still further, a multi-phase electroactive polymer actuator may be employed to provide a unique lighting pattern, e.g., a strobe effect, flashing, etc. Electroactive polymer actuators have application in the lighting industry, in the context of both wall socket (120V/60 Hz power) driven/stationary lighting systems and battery-operated/mobile lighting systems. A flat, small, and lightweight form factor is particularly suitable for point-of-purchase displays and low profile lighting systems. 2009/0147340 and 2010/0033835, the entireties of which are incorporated herein by reference. CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority to International Patent Application No. WO2010/054014, the entireties of which are incorporated herein by reference. Further, unless otherwise indicated, the terms and expressions employed herein have been chosen for the purpose of describing the illustrative embodiments for the convenience of the reader and are not for the purpose of limitation thereof. Upon application of a voltage to the actuator via lead lines 820 coupled to a power supply (not shown), diaphragm 808 relaxes and is moved in the z-axis along with rod 822 and light source 806 are also displaced in the same direction, as illustrated in FIG.

An electromagnetic actuator can be coupled to the LED-based light source and the translucent material and adapted to move the translucent material relative to the radiation generated by the LED-based light source. The translucent member can include a plurality of individual lenticular lenses. By moving the lens array either laterally or transversely with respect to the LED light source array, the light perceived by the user can change in intensity, focus, and beam direction.

9A and 9B, where selected portions of the multi-phase diaphragm 936 of actuator 932 having frame 934 may be activated to change the direction of the reflected rays. Where the array of LEDs contains multiple colors of LED light sources or excites an array of multiple compositions of phosphors, the relative intensities of the different colors of light emitted may be varied by moving the lens array laterally with respect to the LED array so the user will perceive different mixtures of colored light.

For example, for directed light, light-emitting diodes (LEDs) may be employed, whereas conventional incandescent lights may be used to produce diffuse light. Examples of electroactive polymer devices and their applications are described, for example, in U.S. SUMMARY OF THE INVENTION 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 the 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.

FIG. 7 is a side view of the embodiment of the electroactive polymer actuator lenticular device of the present invention shown in FIG. This arrangement provides a reflector “ring”, however, any other suitable arrangement of reflectors and the resulting construct may be employed with the present invention. This embodiment of the optical system of the present invention 600 is illustrated in FIG. The foregoing examples of the present invention are offered for the purpose of illustration and not limitation. 8A and 8B is one that couples the reflector assembly, or one or more reflectors/lenses thereof, to the electroactive polymer actuator to adjust its position relative to the light source(s). Lenticular lens systems enable the viewer to see sequentially two or more images printed in a display such as an artwork 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.

¿Qué es el dolor torácico y cómo tratarlo? The diffuse illumination arises from varying the diffusion angle of light generated by a light emitting diode (LED) system. 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 scope of the invention is to be measured by the appended claims. Dolor de la parte baja de la espalda . The optical system of the present invention may find use in point-of-purchase displays or general illumination applications. In the present invention, an electronic control system is used to afford the smooth motion of the lens element. Suitable electronic control systems are disclosed, for example, in U.S. 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.

These standoffs may be separate piece parts as is known in the art. In some embodiments, the display may include a layer of phosphors placed between the LED light sources and the lens stack. In other embodiments, the light source and the secondary reflector may be stationary and the primary reflector movable relative thereto. Pat. Nos.
