Abstract: An aspect of topic generation includes parsing communications conducted by users through an application. The communications include a communication generated by a sender and response communications received from recipients in reply to the communication generated by the sender. An aspect also includes identifying keywords and indications of sentiment from the parsed communications, determining a focus of the communication generated by the sender based on the keywords identified from the parsing, and formulating a topic for a publication based on criteria including a frequency of occurrence of the keywords in the parsed communications, a threshold level of the indications of sentiment that appear in the parsed communications, and/or a number of the communications containing one or more of the keywords having corresponding timestamps that fall within a threshold period of time. An aspect further includes submitting the topic for publication to the sender.

Abstract: In flat panel displays wherein thermionic electrons are focused to a narrow beam by means of an anode or gating grids, such grids structures are subjected to temperature deformation and vibratory stress. In high resolution displays individual grid structures are placed in close proximity to similar structures, often less than 0.0265 inch apart. Failure to accommodate physical deformation due to wide variations in temperature and or physical stress caused by shock and vibration will cause the grid wires to short circuit and the display to fail. The invention operates to maintain the relative separation of the individual grid structures within a range of temperatures, shock, and vibration.

Abstract: A deflecting apparatus for a flat-panel display having an evacuated display housing and a display screen. The display has phosphor stripes or dots for generating visible radiation when bombarded with electrons when accelerating voltage V.sub.1 is applied to stripes. The invention provides for an elongate electron source positioned in the back of the evacuated display housing for emitting electrons which are guided to the display screen through an anode grid or an electron gating grid located before the display screen. The deflecting apparatus for rendering the beam of electrons emitted from the elongate electron source uniform has a deflecting element or unit which is positioned at the back of the display housing and produces a spatially parabolic potential under the influence of steering potential V.sub.4. This spatially parabolic potential forces the electrons moving in the direction of the anode grid or gating grid to form a uniform beam.

Abstract: A control device may be connected in series or in parallel to a telephone for restricting or routing calls made from the telephone to take advantage of low cost carriers for intra-LATA calls. The serial or parallel connection of the telephone can be detected as well. The device may be programmed for routing depending on the geographical location of the telephone. The central receiving office of the local phone company can be prevented from routing the call by the use of interfering tones.
