Abstract: A self-clocking glyph code is composed of data glyphs which encode logically ordered data values, together with one or more multi-glyph synchronization code patterns. Each of the synchronization code patterns is distinguishable from the data glyphs, but the synchronization code pattern or patterns provide an explicit spatial reference for the data glyphs. To this end, the glyphs of th e synchronization code pattern or patterns are written on the recording medium in accordance with the same spatial formatting rule as the data glyphs, plus at least one additional formatting rule that establishes a predetermined geometric relationship between the glyphs of the synchronization code pattern or patterns and corresponding ones of the spatially formatted data glyphs, such that the logical order of at least a significant number ( ~ 1) of the data glyph s is inferable from the synchronization code pattern or patterns. Preferably, each of the synchronization code patterns is composed of glyphs that are selected from the same finite symbol set as the data glyphs, so the synchronization code pattern or patterns typically are defined by glyph patterns that have a suitably high statistical probability of being unique with respect to any pattern of data glyphs.

Abstract: A heater for an ionographic marking apparatus including a housing, means for generating a supply of marking ions within the housing, means for transporting the marking ions through and out of the housing, and an array of modulation electrodes upon a substrate for controlling the transport of ions out of the housing, the modulation electrodes being spaced from one another by electrically insulating regions. The heater is associated with the array for raising the temperature of the electrically insulating regions so as to prevent the condensation of moisture thereon.

Abstract: PROBLEM TO BE SOLVED: To provide an acoustic print head for ejecting a liquid drop, as required, from the free surface of a liquid fountain, and a method for changing the passage of ejected liquid drop. SOLUTION: A drop 38 of aqueous ink is focused on a substrate 42 using fields 48, 50. The drop 38 is uncharged and an uncharged inductive drop 38 is subjected to a force in an uneven filed, the drop is focuses. More specifically, lateral directional error in the initial speed of the drop 38 is corrected using the fields 48, 50 such that a lateral speed which may cause a displacement of the drop up to 50 μm from an intended position at a place of 1 mm high from the ink surface is corrected to cause a displacement of less than 2.5 μm.

Abstract: PROBLEM TO BE SOLVED: To reduce a metal required for sputtering.
SOLUTION: A flattening structure for use with an associated marking device selected from a plurality of marking device types for making a mark on an associated substrate is provided. The flattening structure includes: a substrate; and a self-lifting spring finger having a non-raising anchor part mounted to the substrate and a separated part extending to the substrate where the separated part has a proximal end and distal end, and the distal end includes a tip for promoting the discharge of a marking fluid, and the separated part of the self-lifting spring finger rises from the surface by etching.

Abstract: PROBLEM TO BE SOLVED: To make ink drops supplied from a plurality of supplying sources uniform. SOLUTION: This system includes a cooling system 260 for compensating non-uniform heating effect in a print head causing the variation of a temperature. By setting a distribution and an efficiency of the cooling system, the temperature of ink is maintained in a constant level through the print head.

Abstract: PROBLEM TO BE SOLVED: To efficiently identify the original spatial position of each glyph by reading a sensitive indication embedded in a medium and the part of two-dimensional data address code and translating them to individual pointers. SOLUTION: A user arranges a camera pen 1710 on a visual mark or near that mark on a glyph address carpet 1732 as a graphical interface and performs selection by pressing a button 1715. By pressing the button 1715, the camera pen 1710 captures the part of the address carpet 1732 under that top end and transmits an image through a frame capture 1728 to a computer 1712 for analysis. At the computer 1712, a processor 1722 executes a program, analyzes the captured part of the glyph address carpet 1732, determines the direction of the image in order to decode and interpret address information encoded into glyph and decodes the address at the position selected on the address carpet.

Abstract: PROBLEM TO BE SOLVED: To provide a detection system which identifies a glyph in real time without performing a computer analysis of an image. SOLUTION: A glyph detector 20 includes a pair of photosensitive elements 22a and 22b which are dimensioned to adapt themselves to two dots of both ends of one glyph and a pair of photosensitive elements 24a and 24b which are dimensioned to overlap on two dots of both ends of the other glyph. The bottom electrode 30 of the pair 22 and 22b is connected to a positive voltage source, while the top electrode 34 of the pair 24a and 24b is connected to a negative voltage source. Output voltage becomes maximum when an area under one pair of the electrode is white and an area under the other pair is black. When one glyph is detected, the maximum output voltage is positive and when it responds to the other glyph, the maximum voltage becomes negative. The maximum positive or negative voltage is shown in 1 or 0 of binary.
