摘要： A networked conferencing device includes at least one speaker, a display and a plurality of environmental sensors such as cameras, microphones, light level sensors, thermal sensors and motion sensors. The conferencing device receives environmental information from the sensors and processes this information to identify qualified events. The identified qualified events are then used to determine a next powered state for the conferencing device. If the next powered state is different than a current powered state, then the conferencing system transitions to the next powered state.

摘要： A resolution enhancement system (10) comprises a focusing lens (12), a beam-splitter (14), first and second imaging elements (16, 18), and a processing circuit (20). The focusing lens (12) receives and transmits an image to the first and second imaging elements (16, 18). The beam-splitter (14) is interposed between the focusing lens (12) and the imaging elements (16, 18). The beam-splitter (14) divides the image from the focusing lens (12) into two sub-images (24, 26) with each of sub-image being directed to a respective imaging element. The first and second imaging elements (16, 18) are positioned such that each element receives a respective half of the original image from the focusing lens (120). The processing circuit (20) receives the two images which can then be combined at the common edge to form a continuous image with twice the resolution.

摘要： The projector (11) of the present invention provides a device for interactively displaying and annotating a document (13) image at two separate locations. The projector consists of an image plate (39) having an array of picture elements for displaying the image; a projection mechanism for projecting the image displayed by the image plate onto a projection screen (49); and a digitizer (41) having a coordinate input array which corresponds to the array of picture elements of the image plate, wherein the image displayed by the image plate changes in response to coordinate inputs to the digitizer. A method for interactively annotating an image communicated between a remote and a local image includes the procedure of simultaneously transmitting to the remote projector, annotations made to an image in the local projector.

摘要： A polarization converter for polarizing a light beam by converting all light waves to the same orientation comprises: 1) a first beam dividing matrix (32) of refractory material for dividing a single, large light beam (34) into smaller sub-beams (36), 2) a second beam focusing matrix (37) for polarizing select portions of the sub-beams, and 3) a series of narrow and shallow polarizing cells. The second beam focusing matrix further comprises a plurality of concave lenses (48) for redirecting each sub-beam and quarter wave retarders (54) disposed in alignment with, and adjacent to, the reflective side of an equal plurality of mirror segments. The polarizing cells include either a first beamsplitter or a second beamsplitter, where the first beamsplitters and second beamsplitters are disposed in opposing diagonal fashion and in an alternating manner. Lightwaves of a selected polarization pass directly through the first beamsplitter and out of the polarizing cell, while all other lightwaves are horizontally reflected by the first beamsplitter and directed onto the second beamsplitter where they are redirected toward the quarter wave retarder. The reflected light passes through the quarter wave retarder, reflects off of the mirror and again passes through the quarter wave retarder.
