摘要： A user interface is implemented using visual indicia and a background for the visual indicia that encodes address information. The background appears visually as a stipple pattern, but is implemented using glyphs which form an address carpet that encodes address information uniquely identifying each location of the user interface. An image capture device is used to capture an area of the address carpet that is at or near visual indicia of interest to the user while selecting a location in the visual indicia. The image capture device captures the area of interest, and transmits the image area to a computer for processing. The computer first determines the proper orientation of the image, and then decodes the information encoded by the glyphs. The decoding results in an X, Y address identifying the location of the captured area in the address carpet and, by reference, the address of the selected location. Based on the address, the computer may perform an operation associated with the area.

摘要： A captured image includes a portion of a set of two-dimensional address codes. The portion of address codes can be decoded to determine a discrete pointer uniquely defining the portion. The captured image is first processed to determine the orientation of the portion, and then decoded based on the orientation to determine the discrete pointer. To determine the orientation of the portion, the portion is first analyzed to determine values at discrete locations within the portion. The values at each location form a matrix of binary data. The values of the matrix are then correlated to determine an orientation of the captured portion of two dimensional address codes. After determining the orientation of the portion, the values can be further analyzed to determine a discrete pointer that identifies the location of the portion within the address space defined by the two-dimensional address codes.

摘要： A self-clocking glyph code is provided for encoding n-bit long digital values (where n>1) in a logically ordered sequence of composite glyphs 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.

摘要： 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 the 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 glyphs 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.

摘要： Bands of predetectors (92) detect the approach of lines of glyphs (12, 14) within an image being scanned. Linear lines or arrays of glyph detectors (116, 118, 120) are sampled in accordance with the detected approach of lines of glyphs. Each detector array includes a plurality of analog glyph detectors (20, 50) which respond to the presence of glyphs with a characteristic analog output. Preferably, the glyph detectors generate a corresponding analog output of a first polarity or other characteristic in response to glyphs of a first orientation and an output of a second polarity or characteristic in response to glyphs of a second orientation. The analog signals which are characteristic of the detection of a glyph are converted into binary 1's and 0's in accordance with the polarity or other characteristic of the signals. In this manner, glyphs are detected by analog detectors and the information encoded in the glyphs is directly output as a binary signal without computer analysis of the image.

摘要： A system for fluid transport is provided where a quantity of fluid is held in a reservoir. A droplet generator is employed to generate droplets from the fluid, for example a nozzle-based system or a nozzleless system such as an acoustic ejection system. A generated droplet has a trajectory whereby it arrives at a target. A circuit is used to modify one or more characteristics of the generated droplet in a way which increases the likelihood that the droplet will not splash or bounce when it arrives at the target. The circuit may in different embodiments control the speed of the droplet or the Weber number of the droplet. The circuit may create an electric field in an area of space where the droplet passes. The circuit may charge the droplet by causing it to contact ions.
