A number of illustrative variations may include a method of relative localization via the use of simultaneous location and mapping gear sets.

A rotatable stroboscopic animation device with a rotatable base portion and at least one light source. An angular-velocity-dependent flashing system flashes the at least one light source according to a predetermined flash mode dependent on the angular velocity of the base portion to produce coherent, automatic stroboscopic animation of images retained by the base portion. The flashing system can comprise an angular velocity determination system in cooperation with an illumination system. Angular velocity can be determined by an orienting system, such as a compass, in combination with a sampling system, a gyroscope, or a rotational sensor. A flash mode selection mechanism, which can be manual or automatic, permits a selection of a flash mode from among a plurality of flash modes. A manual flash mode selection mechanism can be formed by relatively pivotable upper and lower disks of the base portion. Animation disks can have indications of predetermined flash modes.

The present invention provides a photo-substrate for printing of lenticular images that comprises a lenticular lens array, and an energy-reactive material adhered to the backside of the lenticular lens array. According to the methods of the present invention, the lenticular image is printed directly through the lenticular lens array onto the energy-reactive material, using, for example, collimated light or laser. The photo-substrate of the present invention can be adapted for large scale or industrial production to print lenticular images on a wide array of substrates, including such things as packaging and clothing.

A lighting scriptfor use by a lighting controller to control at least one luminaire to render illumination effects, as the video content is outputted in a space illuminated by the at least one luminaire, synchronously with the outputting of the video contentis generated as follows. Frame image data of the video content is processed to determine at least one colour palette of the frame image data. A sequence of illumination effectsto be rendered during the outputting of the video content and which is modifiable by a useris displayed to the user. The displayed sequence conveys at least one illumination colour derived from the determined colour palette to be rendered in at least one of the illumination effects. The generated lighting script is for rendering the modified sequence of illumination effects.

One embodiment of the present disclosure may take the form of a projection module for projecting onto a projection surface. The projection module includes a light source emitting a beam of light, a diffractive optical element in optical communication with the light source, the diffractive optical element acts to split the beam of light into a plurality of diffracted light beams, a lens assembly in optical communication with the diffractive optical element and configured to converge the diffracted light beams onto the projection surface, and a motion assembly connected to at least one of the light source or the lens assembly. The motion assembly changes an orientation of the diffractive light beams relative to the lens assembly.

A secure lens sheet or layer suitable for use in a micro-optic system, which is made up of a plurality of joined fine lens arrays (e.g., joined fine lenticular and/or joined fine non-cylindrical lens arrays), is provided. Each array has a lens pitch different from adjacent or contiguous arrays and/or is orientated in a direction different from adjacent or contiguous arrays. A micro-optic security device, which utilizes the inventive secure lens sheet and one or more overlying or underlying arrangements of micro-sized image icons (e.g., line data), is also provided. The image icon arrangement(s) and the secure lens layer are configured such that one or more synthetic images are projected by the security device. These projected images may show a number of different optical effects. With such a combination lens layer, some regions could be optically active when the device is tilted in one direction, some could be active when tilted in the opposite direction, and some areas could be active when the device is tilted in either (or any) direction. The inventive micro-optic security device may be partially embedded in and/or mounted on a surface of a security article (e.g., paper or polymer security document, label, card), or integrated therein.
