Abstract: A flat panel display which allows for precise detection of the location of the cursor with respect to the displayed image. Parallax problems are eliminated by focusing the displayed image on a panel (35) by projection through the panel. The location of a stylus (114) is determined using known digitizing techniques together with the use of an erect, unity magnification imaging lens array (34) for displaying the projected image. Alternatively, the location of the stylus with respect to the displayed image is determined by causing the stylus to feed signals, for example optical signals, through a significant portion of the optical path used for displaying the image.

Abstract: A dryer (10) used to remove a flammable solvent or vapors from a traveling web of material (12) supported in flotation by opposing air bars (146a-146n). The dryer consists of a large metallic cylinder (14) through which the web of material moves longitudinally. Seals (16,18) in the ends of the metallic cylinder at the point of entry and point of exit of the traveling web provide for a control system to maintain the desired environment under controlled pressure within the metallic cylinder. The web of material travels successively through one or more zones (bz1,bz2,bz3) within the metallic cylinder. In each drying zone, the web of material is exposed to pressurized atmosphere at predetermined temperatures. The solvent is recovered from the pressurized atmosphere by rapid cooling, membrane separation, or absorption. Sensors within each zone of the dryer measure the oxygen content of the pressurized atmosphere. If the oxygen content exceeds a given threshold, pressurized nitrogen or other inert gas is added. Through the use of a carbon bed (60) at the last zone, pressurized atmosphere from that zone is rendered sufficiently free of solvent to be exhausted to the air or to a nitrogen recovery unit, thereby maintaining the desired overall pressure within the metallic cylinder.
