摘要： A method of making a louver device for a light guide screen. More specifically, in a specific embodiment, a transparent layer is provided. A plurality of similarly angled surfaces are established within the transparent layer. The angled surfaces are coated with a light-reflective material such that the coated surfaces define a plurality of light paths through the transparent layer.

摘要： In a particular, a high contrast projection system configured for front or rear projection includes a screen having a viewing side and a back side opposite thereto. The screen includes a transparent layer of material having louver members disposed therein to provide fractional reflective coverage across the width of the transparent material. The screen discriminates an image signal light from a source, such as a projector, from ambient light incident upon the viewing surface. The image signal light is redirected over a range of angles relative to a normal to the viewing side, while the majority of ambient light is directed generally toward the back side, for example passing through the transparent material between louver members. A light absorbing back panel adjacent to the back side absorbs the ambient light further improving contrast.

摘要： Electronic writing systems and methods are described. In one aspect, an electronic writing system includes an elongated housing, an inertial sensor, an optical sensor, and a tracking module. The elongated housing has an optical input. The inertial sensor is attached to the housing and is operable to generate data indicative of movement of the housing relative to an inertial reference frame. The optical sensor is attached to the housing and is operable to generate data from light received through the optical input. The tracking module is operable to compute relative displacement data from inertial movement data corresponding to data generated by the inertial sensor. The tracking module also is operable to detect at least one calibrated position from calibration data encoded in optical data generated from light received by the optical sensor.
