Abstract: Disclosed embodiments may include a permanent magnet system that will move rotor assembly with respect to the position of a stator assembly. A stator assembly may be stationary and take the form of a circular system while a rotor assembly may be magnetically urged in rotational movement within the stator assembly. Both the rotor and stator assemblies may be populated with permanent magnet pole pieces such that the rotating magnetic field of the rotor interacts with the static magnetic field of the stator and thereby achieves a magnetic interaction that urges rotation of the rotor assembly. By virtue of the moving magnetic fields of the rotor, positions of the rotor and stator magnets, the attraction to repulsion forces of the rotor magnets may be uneven and thus add to the rotational energy of the rotor.

Abstract: A display system is convertible between a planar display and a stereoscopic display. The system includes a flat panel display having a display surface. An alignment strip is affixed to the flat panel display proximate to the display surface. A lenticular screen is removably held in close proximity to the display surface by the alignment strip. An alignment method using software to generate test patterns ensures proper alignment of the lenticular screen the the display. A rotational pattern is displayed, and the user moves the pattern to align it with the lenticular slant. A vertical test pattern is displayed, and the user moves the pattern to center it within the display field.

Abstract: A method and apparatus for optimizing viewing distance for a stereogram system. In a stereogram, an image is held in close juxtaposition with a lenticular screen. In the invention, a data store is used to store optimum pitch values for specified viewing distances. An interdigitation program then acts on the table values and creates a mapping of interdigitated views for each viewing distance. The user can then select or specify a desired viewing distance, and the optimum mapping of views is automatically chosen for display.

Abstract: A neutralizing sheet for an autostereoscopic image viewing system. The image viewing system includes a lenticular sheet covering a display screen. The neutralizing sheet including a pliable portion and is movable between a first position and a second position. The pliable portion has a refractive index similar to the lenticular sheet. When pressed into the lenticular sheet to define the first position, the pliable portion deforms to assume the shape of the lenticular sheet. Thus, refraction through the lenticular sheet is neutralized and viewing of planar images is enabled. In the second position, the neutralizing sheet is separated from the lenticular sheet and viewing of stereoscopic images is enabled.
