A table system includes a touch screen integrated in a table top, a computer system in communication with the touch screen, the touch screen being configured to serve as a primary input to the computer and to display multiple active sections at different orientations corresponding to different seating locations on the table top simultaneously, and a secondary screen, located away from the touch screen, in communication with the computer system, the secondary screen being configured to continuously display media files stored on the computer system at a single orientation and to be viewed from the different seating locations simultaneous with use of the touch screen, the touch screen configured to display representations of media files to be displayed on the secondary screen and to serve as selection input for the media files.

Multimedia, multiuser system and associated methods

An optical assembly includes a first transparent substrate having first and second surfaces, a second transparent substrate having substantially parallel third and fourth surfaces, a reflective portion on the second transparent substrate, a plurality of filters between the first substrate and the reflective portion, the plurality of filters filtering light beams incident thereon, the plurality of filters and the reflective portion forming a bounce cavity within the second transparent substrate, a collimating lens for collimating light beams to be input to the bounce cavity, a tilt mechanism for introducing tilt to light beams input to the bounce cavity; an input port receiving light beams and an output port transmitting light beams. The tilt mechanism may be between the first and second substrate.

Optical assembly

An optical element may include a substrate including a diffractive structure having multiple periods, at least one period of the multiple periods having multiple steps, heights of the multiple steps non-monotonically increasing across the at least one period. The optical element may be used with at least two wavelengths, e.g., three wavelengths, may be on a single surface and may provide an efficiency of at least 50% for all wavelengths.

Optical wavelength division coupler and associated methods

A broadband diffractive diffuser contains at least three levels, with approximately a phase shift of .pi. between at least two of the at least three levels. Such a diffuser provides light with more than two phasor vectors at the zero order. The presence of the more than two phasor vectors reduces the zero order diffraction efficiency at non-design wavelength, increasing the usefulness of the diffuser at wavelengths other than the design wavelength. Preferably, the diffractive diffuser includes a plurality of regions, approximately 50% of an area of the plurality of regions presenting a phase shift of .pi. at a design wavelength, approximately 25% of the area of the plurality of regions presenting a phase shift of 2.pi. at the design wavelength, and approximately 25% of the area of the plurality of regions presenting a phase shift of 0 at the design wavelength. Such a diffractive diffuser may be formed by logical operations between two diffractive diffuser patterns, by adding two diffractive diffuser patterns, or by pixel-by-pixel scanning.
