Abstract: Pixel transporting system includes at least one sender device, at least one receiver device, wherein the sender device and receiver device are coupled and configured by the pixel transport system to process a signal from a sender device and transport the processed signal from the sender device to the receiver device, wherein processing of the signal comprises rendering a partial subset or complete set of source pixels based on a mapping of a virtual projection from a source endpoint to a sink endpoint. Optionally, virtual projection is only partially mapped onto the sink and results in only the intersecting subset of source pixels for transport to the sender device. Also, optionally, the virtual projection is completely mapped onto the sink and results in a complete set of source pixels for transport to the sender device.

Abstract: Information sources are selected in accordance with a subject matter of interest to a user, where the subject matter of interest is identifiable by a plurality of sets of subject-related data, and each set has an indication of at least one context in which the set is of interest to the user. The state of the user is tracked, one or more contexts are identified from the tracked state, at least some sets of subject-related data are selected in accordance with a predetermined relationship between at least some of the identified contexts and said indication of context, a list of information sources is generated based on the selected sets of subject-related data, and the list is transmitted to a terminal associated with the user so as to allow the user to select an information source of interest and thereby to access information from the source.

Abstract: A method of changing a user profile involves the system suggesting a change which includes one or more selection choices representative of the suggested change. The user makes one or more selections which results in temporal modification of the user profile. The method further involves monitoring user action in respect of the temporal modification, and, in accordance with the user action satisfying predetermined criteria, permanently changing the user profile based on the user selections.

Abstract: The invention is concerned with a method of selecting information sources in accordance with a subject matter of interest to a user, where the subject matter of interest is identifiable by a plurality of sets of subject-related data, and each set has an indication of at least one context in which the set is of interest to the user.

Abstract: The invention is concerned with a method of changing a profile representing subject matter of interest to a user, where the profile includes a plurality of sets of subject-related data.

Abstract: A dust-proof element for reducing creeping dispersion of dust along a free surface formed as one of locally limited dust trap element (5) and dust barrier (7) having a surface with an artificial pimpled microcrystalline structure with bumps and indentations having a size in a range from 5 to 100 &mgr;m and spaced from each other by a distance from 5 to 200 &mgr;m, and a method of protecting hand-held tools and working tools with the dust-proof element.
