Abstract: The present invention describes a method for selectively delivering electronic messages to an identified user or users in a system of mobile and fixed devices, including multiple display devices and multiple users, based on the context of the system and the environment of the identified user. Electronic messages intended for an identified user or users may be given a level of privacy and a level priority, and contextual attributes for its delivery may be specified. The system perceives contextual attributes for the recipient user or users, including display devices in close proximity to the identified users, and determines a display property for said electronic message based on the contextual attributes, the user profile properties of each user, and the level of privacy and level of priority of the electronic message.

Abstract: A system and method for creating data values suitable for producing a gray scaled approximation of a facsimile image on a lower resolution display. Facsimile image data is compressed based upon horizontal and vertical scaling factors that depend upon the number and organization of display screen pixels to be used to produce the gray scaled image verses the number and organization of pixels in the facsimile image. A conversion vector having entries in a one-to-one relationship with the display pixels of a display scan line is formed. Numerical values are then added to or subtracted from the conversion vector entries associated with the beginning and ending of the black runs of the facsimile image, as determined by using the horizontal scaling factor. The numerical values themselves depend upon how much of the conversion vector entry is spanned by the scaled black facsimile image run length.
