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).

English Abstract
A laser projection system wherein speckle is suppressed through beam-path
displacement, by deflecting the beam during projection, thereby avoiding both
absorption and diffusion of the beam while preserving pseudocollimation
(noncrossing rays). Path displacement is achieved by scanning the beam on
liquid crystal light valves (LCLV's) (30), which also provide enhancements -
in energy efficiency, brightness, contrast, beam uniformity (by suppressing
both laser-mode ripple and artifacts). Preferably deflection is performed by a
mirror (20) mounted on a galvanometer or motor (21) for oscillation; images
are written incrementally on successive portions of an LCLV control stage
while the laser "reading beam" is synchronized on an output stage. Beam
splitter analyzer cubes (25) are preferred over polarizing sheets.
French Abstract
Les lignes laser à 635 nm ou plus (idéalement 647 nm) sont préférées pour le rouge, donnant
des images, satisfaisantes du point de vue énergétiques, brillantes et à mouvement rapide aux
couleurs riches et pleines comparables à un film. Les lignes vertes et bleues sont également
utilisées et le cyan retenu pour un bon mélange de couleurs, un survoltage supplémentaire
lumière couleur et sa contribution à la suppression du chatoiement. Ce chatoiement est supprimé
par le déplacement du parcours faisceau - par déviation du faisceau durant la projection, ce qui
supprime tant son absorption que sa diffusion tout en conservant la pseudo-collimation (rayons
non croisés), ce qui est important pour la netteté illimitée. Le déplacement du parcours est
obtenu par balayage du faisceau sur les valves à cristaux liquides (LCLV), ce qui donne lieu à
plusieurs améliorations en matière d'efficacité énergétique, de brillance, de contraste et
d'homogénéité du faisceau (par suppression à la fois des ondulations mode laser et des
artefacts) et une rotation de faisceau pratique pour le transfert de faisceau entre les étages de
l'appareil. C'est, de préférence, un miroir, monté sur un galvanomètre ou un moteur aux fins
d'une oscillation rotative, qui assure la déviation. Les images sont écrites de manière
incrémentielle sur des parties successives de l'étage de commande des LCLV (optique ou
électronique) tandis que le faisceau laser est synchronisé sur l'étage de sortie. Le faisceau est
façonné, avec très peu de pertes d'énergie, aux fins d'un masquage, en un profil transversal peu
profond qui est décalé sur l'écran de visualisation ainsi que sur les LCLV. Des cubes
analyseurs/diviseurs de faisceau sont préférés au-dessus de feuilles polarisantes. La modulation
spatiale assurée par une LCLV et maintenue par pseudo-collimation permet la formation
d'images sur des supports de projection irréguliers avec des parties à des distances différentes
du projecteur- y compris des dômes, des sculptures des monuments, des bâtiments, des chutes
d'eau, des embruns, du brouillard, des nuages, de la glace, des mousselines et autres structures
à étage, des arbres et autres frondaisons, des terres et des surfaces rocheuses et même des
assemblages de créatures vivantes, des personnes y compris.
