摘要： Techniques for generating temporary digital ink on media are provided. Marks or gestures are made using one or more temporary digital inks on media, such as an digital document. Digital ink may be dynamically determined to be permanent or temporary. Each mark or gesture using temporary digital inks may fade based on at least one condition. The conditions include a predetermined time determined based on, a first stroke of the temporary digital ink, completion of the temporary digital ink, appearance of the temporary digital ink to another user, a first stroke of a succeeding group of digital ink, and a stroke of the succeeding digital ink is completed. Conditions may also include changing display attributes, such as color and thickness of digital ink, and fading or switching in reaction to an audio or video signal.

摘要： An automated test to tell computers and humans apart is disclosed, comprising displaying on a computer screen an animation comprising of a foreground and a background, one of the foreground comprising a plurality of typographical characters and the other comprising partial obstruction of the typographical characters, and wherein the animation comprises relative motion between the background and foreground. The automated test may comprise displaying on a computer screen an image, and requiring the user to perform operation on the image to resolve an encoded solution. The test may also comprise displaying on a computer screen a video clip, and requiring a user to provide an input corresponding to subject matter presented in the video clip.

摘要： Techniques are provided for determining relevant information from a document based on document structure. A document is selected and structural elements within the document having a dominance relationship are determined. A first location within the document is selected. The structural element surrounding the first location is determined and the surrounding and non-surrounding structural elements are characterized. Additional documents are associated with the first location in the surrounding structural element based on the surrounding structural element characterization and the non-surrounding structural element characterization. Techniques for dynamically determining annotations for images based on document structure are also provided.

摘要： Described is a technique for providing shared access to an encrypted portable memory device which improves both usability and security by allowing the owner of the encrypted storage device to designate access to specified files only to the next host to mount the secure disk. The number of steps required to perform a file sharing operation is greatly reduced with this system and access to the contents of the protected storage device can be granted with greater granularity.

摘要： A system for providing a dynamic audio-visual environment using an eSurface situated in a room environment; a projector situated for projecting images onto the eSurface; a camera situated to picture the room environment; a central processor coupled to the eSurface, the projector and the camera. The processor receives pictures from the camera for detecting the location of the eSurface; and controls the projector to aim its projection beam onto the eSurface. The eSurface is a sheet-like surface having the property of accepting optically projected image when powered, and retaining the projected image after the power is turned off.
