Abstract: A technique for enhancing the illusion of physical presence in a common space during a multipoint video conference is disclosed. The technique may include controlling the appearance of a first portion of the video images separately from an appearance of a second portion of the video images to achieve a consistent image appearance across the multipoint videoconference.

Abstract: Embodiments of displaying information are disclosed.

Abstract: A method and apparatus senses light reflected off of a surface of an object at angles with respect to incident light.

Abstract: In one embodiment, a method transmits data between an object and one or more communication devices on a perimeter of a display surface.

Abstract: In embodiments, data corresponding to an object is determined from symbology.

Abstract: Embodiments including a surface are disclosed.

Abstract: An embodiment of an apparatus includes a surface and a projector to project light onto the surface. The embodiment further includes a first lens array to receive the light from a first region of the surface and a second lens array to receive the light from a second region of the surface.

Abstract: Infrared light is emitted towards a surface. The infrared light is redirected by an object positioned on the surface. The infrared light as redirected by the objected is detected. A position of the object on the surface is determined based on the infrared light detected.

Abstract: A filter for a printhead assembly includes a frame having an opening formed therein, filter material enclosing the opening of the frame, and a fluid fitting associated with the frame, the fluid fitting including a fluid port offset from the frame and a fluid passage communicated with the opening of the frame and the fluid port.

Abstract: Valves, ink delivery systems, and a method are provided for moving ink from an ink supply source to a printhead. The printhead ejects ink onto a print media to satisfy a print job. An inlet receives ink from the ink supply source within a central cavity of a valve. The ink flows through the central cavity to an outlet that is interfaced to the printhead. Moreover, the central cavity is segmented into first and second regions. In one embodiment, an Elastomer material segments the central cavity. The first region includes a seal adapted to close the inlet when the valve is in a closed position. The second region includes an actuation means for moving the seal to open and closed positions. Further, in one embodiment, the second region is humidified.
