Filed:

Dec 19, 2001

Appl. No.:

10/027784

Inventors:

Paul V. Long - Newberg OR
David E. Slobodin - Lake Oswego OR

Assignee:

InFocus Corporation - Wilsonville OR

International Classification:

G03B 2100

US Classification:

353 31, 353 33, 353 34, 353 99, 353 38, 359372

Abstract:

Projected systems ( ) include light source apparatuses ( ) for programming narrow bands of unpolarized blue, green, and red light to associated reflective imaging devices that reflect selected patterns of the blue, green, and red light into a dichroic cross-combiner assembly ( ), which recombines the light into a composite image and directs it into a projection lens ( ) The reflective imaging devices are preferably micromirror displays ( ) having an array of pivotable micromirrors ( ) that direct on-state micromirror light to the projection lens and direct off-state micromirror light to a light absorbing surface ( ).

International Classification:

G09G 5/00

US Classification:

345 23, 709225, 353 30

Abstract:

A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of transmission bandwidth by transmitting a subset of the digital image data. The subset image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. Header data is provided to further describe the subset image data. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received. A wireless to digital visual interface (DVI) graphics engine decompresses and renders the image for output to a DVI connector receptacle.

International Classification:

G06F 3/01

US Classification:

702178, 702177, 702187, 702188

Abstract:

A method and apparatus for a collaborative meeting room system. In response to user input, an electronic device starts a meeting timer to begin timing a meeting at which a previously-created meeting agenda is used. The electronic device causes a projection device to project a running meeting timer, as a result of starting the meeting timer. An agenda item included in the previously-created meeting agenda is retrieved, as a result of starting the meeting timer. The electronic device causes the projection device to project meeting minutes for the agenda item, as a result of retrieving the agenda item.
