Abstract: A self-clocking glyph code (31) is composed of data glyphs (34) which encode logically ordered data values, together with one or more multi-glyph synchronization code patterns (33). Each of the synchronization code patterns (33) is distinguishable from the data glyphs (34), but the synchronization code pattern (33) or patterns provide an explicit spatial reference for the data glyphs. To this end, the glyphs (37) of the synchronization code pattern (33) or patterns are written on the recording medium (35) in accordance with the same spatial formatting rule as the data glyphs (34), plus at least one additional formatting rule that establishes a predetermined geometric relationship between the glyphs of the synchronization code pattern or patterns (33) and corresponding ones of the spatially formatted data glyphs (34), such that the logical order of at least a significant number (>> 1)of the data glyphs (34) is inferable from the synchronization code pattern or patterns (33). Preferably, each of the synchronization code patterns (33) is composed of glyphs (37) that are selected from the same finite symbol set as the data glyphs (34), so the synchronization code pattern or patterns (33) 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 device for moving an object, such as a sheet of paper (20) or other substrate, includes a base element (10), a drive mechanism (15) to move the base element (10) in first and second directions (7), such as by vibration, and a plurality of flexible ratchets (5) fixedly secured to the base element (10). As the base element vibrates, the ratchets (5) advance the sheet of paper in a direction (9) perpendicular to the direction (7) of vibration of the base element (10). Pluralities of base elements and drive mechanisms can be provided (Figs. 6,7) to direct movement of the substrate in various directions.

Abstract: Planar hergestellte Struktur (201, 401, 501, 601) zur Verwendung in einem zugehörigen Markierungsgerät, das aus mehreren Markierungsgerätearten zur Erzeugung von Markierungen auf einem zugehörigen Substrat ausgewählt ist, wobei die hergestellte Struktur umfasst:ein Substrat (206),einen selbsthebenden Federfinger (200) mit einem nicht angehobenen Ankerbereich (208), der an dem Substrat angebracht ist, und einem Auslösebereich (202), der sich über dem Substrat (206) erstreckt, wobei der Auslösebereich (202) ein zum Rand des nicht angehobenen Ankerbereichs (208) zugewandtes Ende (212) und ein abgewandtes Ende aufweist, wobei das abgewandte Ende eine Spitze (202T) umfasst, die ausgebildet ist, als ein elektrostatischer Feldkonzentrator zu dienen, um die elektrostatische Extraktion von Markierungsfluiden aus einem Reservoir mit Markierungsfluiden des zugehörigen Markierungsgeräts in Richtung einer zu markierenden Oberfläche zu ermöglichen.

Abstract: A self-clocking glyph code (23) is provided for encoding n-bit long digital values (where n>1) in a logically ordered sequence of composite glyphs (31a-31d) that are written, printed, or otherwise recorded on a hardcopy recording medium in accordance with a predetermined spatial formatting rule. As used herein, a "composite glyph" is a graphical symbol that has a plurality of predefined, substantially orthogonal, graphical characteristics; each of which is capable of assuming any one of a plurality of predefined graphical states. An n-bit long digital value is distributively encoded in a glyph of this type by decomposing its n-bits, prior to or during the encoding, into a plurality of shorter, ordered, non-overlapping bit strings. The digital values of these bit strings, in turn, are encoded in the states of respective graphical characteristics of the composite glyph in a predetermined logical order, thereby preserving the logical ordering of the bit strings.
