Display system with nonvisible data projection
TLDR
A display system includes an illumination source configured to produce visible and nonvisible radiation and to direct the visible and notvisible radiation along an optical path; and a modulator disposed in the optical path configured to modulate the visible radiation to generate a visible image, and to modify the nonvisible data stream as discussed by the authors.Abstract:

Patent
A method for fabricating a structure for a microelectromechanical systems (mems) device
TL;DR: In this paper, a microfabrication process for MEMS devices is described, which may be used to manufacture a MEMS device, and the process comprises depositing one or a stack of layers on a base layer, said one layer or an uppermost layer in said stack being a sacrificial layer; patterning said one or stack of layered layers to provide at least one aperture therethrough through which said base layer is exposed; depositing a photosensitive layer over said layer; and passing light through said at least 1 aperture to expose said photo sensitive layer.
Patent
Process for modifying offset voltage characteristics of an interferometric modulator
TL;DR: In this paper, a process for modifying the processing parameters to shift the non-zero offset voltage closer to zero has been developed, which may have improved performance and/or simpler drive schemes.

Interactive movement and contact simulation game
TL;DR: In this article, the authors present an interactive contact and simulation game in which a player and a 3D computer generated image interact in simulated physical contact, where a plurality of position sensing and impact generating means are secured to various locations on each player's body.
Patent
Coordinate input system and display apparatus
TL;DR: In this paper, the authors present an object to provide a coordinate input system for image display, which uses a ray reflecting indicator smaller in size and lighter in weight than a light pen and to improve ease of use.
Patent
Method and apparatus for detecting the location of a light source
TL;DR: In this article, the position of a remotely generated spot from a laser illuminator is detected by a so-called sensor which is positioned to detect light from the spot which is diffusely reflected off the screen along the portion of the optical path between the computer-driven light modulator and the screen.

Color wheel synchronization apparatus and method
Steven E. Stark,Edmund D. Passon +1 more
TL;DR: In this article, a multimedia projector employing a color wheel (42) in a frame sequential color display system includes a light sensor (68) positioned to receive light scattered from a point in an optical path (34) after the color wheel.
Patent
Method and apparatus for inhibiting projection of selected areas of a projected image
TL;DR: In this article, an infrared source close to the video projector uniformly floods the projection screen with non-visible infrared radiation, and the subject can then look directly at an audience without being blinded by the projector.
