Troyer Patent Portfolio update: Canadian patent granted January 15, 2013 that contain a combination claims of Troyer four US patents 2001, 2005,2006 and 2012. claims. The Canadian patent office is very thorough, especially with the upgraded global search engines. This is an important validation for Troyer, declaring that there is no prior art for her innovation.
Basic patent: laser projector apparatus with expanded laser beam directed to a reflective light valve with the 635 nm red or over. Cyan can be added to the blue green. Great blacks and whites are created and colors in the full spectrum (like nature). The spatially modulated laser beams keeps their inherent quality of polarization, collimation and coherence to the screen. The images have IF IT IS—infinite focus, instant transformation and innate sharpness automatically adjusting to any irregular surfaces such as domes and curved screens. The laser apparatus is the linchpin for the HIVE: holographic immersive virtual environments (holodeck playpen space); edutainment (content); edutainer (performance).
Each spatially modulated pixel has an infinite depth of focus attribute that provides sharp 3D depth and sharp focused dimensional images (domes, simulation, irregular surfaces, water screens, etc.). The laser apparatus includes a camera/ sensor as part of the projector. Film, slides, microscopic organisms, etc. can be captured by the camera and amplified without pixels to a curved screen image. The laser apparatus is like an overhead projector. The live action is captured and amplified on the dome. Live action gestures can be sensor evaluated (Kinect camera) and integrated. Small dimensional high resolution pictures from an OLED or other device can be captured. A hologram or 3D laser modulated image is captured and amplified.
The laser apparatus can be an advanced telecine copying film; also video and still images (slides). The telecine images are captured on a small curved screen, the video feed transformed to full color Z depth dimensional moving pictures. The capture is real time and is agnostic to the frame rate. The laser apparatus is a digital intermediary tool that provides instant transformation to images (full color, curved space, Z depth factor, 2D to 3D).

  2. 2. Third-party disclaimerEnglish AbstractA laser projection system wherein speckle is suppressed through beam-pathdisplacement, by deflecting the beam during projection, thereby avoiding bothabsorption and diffusion of the beam while preserving pseudocollimation(noncrossing rays). Path displacement is achieved by scanning the beam onliquid crystal light valves (LCLVs) (30), which also provide enhancements -in energy efficiency, brightness, contrast, beam uniformity (by suppressingboth laser-mode ripple and artifacts). Preferably deflection is performed by amirror (20) mounted on a galvanometer or motor (21) for oscillation; imagesare written incrementally on successive portions of an LCLV control stagewhile the laser "reading beam" is synchronized on an output stage. Beamsplitter analyzer cubes (25) are preferred over polarizing sheets.French AbstractLes lignes laser à 635 nm ou plus (idéalement 647 nm) sont préférées pour le rouge, donnantdes images, satisfaisantes du point de vue énergétiques, brillantes et à mouvement rapide auxcouleurs riches et pleines comparables à un film. Les lignes vertes et bleues sont égalementutilisées et le cyan retenu pour un bon mélange de couleurs, un survoltage supplémentairelumière couleur et sa contribution à la suppression du chatoiement. Ce chatoiement est supprimépar le déplacement du parcours faisceau - par déviation du faisceau durant la projection, ce quisupprime tant son absorption que sa diffusion tout en conservant la pseudo-collimation (rayonsnon croisés), ce qui est important pour la netteté illimitée. Le déplacement du parcours estobtenu par balayage du faisceau sur les valves à cristaux liquides (LCLV), ce qui donne lieu àplusieurs améliorations en matière defficacité énergétique, de brillance, de contraste etdhomogénéité du faisceau (par suppression à la fois des ondulations mode laser et desartefacts) et une rotation de faisceau pratique pour le transfert de faisceau entre les étages delappareil. Cest, de préférence, un miroir, monté sur un galvanomètre ou un moteur aux finsdune oscillation rotative, qui assure la déviation. Les images sont écrites de manièreincrémentielle sur des parties successives de létage de commande des LCLV (optique ouélectronique) tandis que le faisceau laser est synchronisé sur létage de sortie. Le faisceau estfaçonné, avec très peu de pertes dénergie, aux fins dun masquage, en un profil transversal peuprofond qui est décalé sur lécran de visualisation ainsi que sur les LCLV. Des cubesanalyseurs/diviseurs de faisceau sont préférés au-dessus de feuilles polarisantes. La modulationspatiale assurée par une LCLV et maintenue par pseudo-collimation permet la formationdimages sur des supports de projection irréguliers avec des parties à des distances différentesdu projecteur- y compris des dômes, des sculptures des monuments, des bâtiments, des chutesdeau, des embruns, du brouillard, des nuages, de la glace, des mousselines et autres structuresà étage, des arbres et autres frondaisons, des terres et des surfaces rocheuses et même desassemblages de créatures vivantes, des personnes y compris.
