摘要： Pixel elements capable of imaging spatial intensity variations within themselves, and displays comprised of such elements, are described. The pixel elements include a resistance layer disposed between at least one set of electrodes. Over that resistance layer is a liquid crystal material. Over that liquid crystal material is a field electrode. In operation a voltage, whose components are referenced to the field electrode, is applied across the resistance layer. The resulting current flow induces a spatially varying electric field between the field electrode and the resistance layer. That spatially varying electric field results in a corresponding response by the liquid crystal layer which results in a spatially varying light transmission through the liquid crystal material. By varying the voltage across the resistance layer and/or the voltage applied to the field electrode varying amounts of light transmission can be achieved.

摘要： An image detection and pixel processing system includes a plurality of detector elements for receiving an image. The detector elements are subdivided into a plurality of macrodetectors, with each macrodetector constituting four or more detector elements, and with each macrodetector providing information for determining both a total light intensity value within the macrodetector and a centroid of light intensity indicative of light intensity position within the macrodetector. An image processing assembly receives information from the plurality of macrodetectors, with the image processing assembly relating a pixel and its encompassed subpixel area to each corresponding macrodetector, and further determining the total light intensity within the pixel and the centroid of light intensity within the subpixel. The image processing assembly is capable of rendering each subpixel area as an edge when magnitude of the centroid of light intensity is greater than a predetermined threshold.

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： An apparatus for imaging books or other bound documents which includes a cradle for supporting a book and an optical system positioned above the cradle. The optical system is mounted for movement along a vertical axis toward and away from the cradle. It includes an upper portion supporting a camera and mirror arrangement and a lower portion comprising a platen assembly. The upper and lower portions are mounted for independent movement along the vertical axis over a first range of travel remote from the cradle, and are coupled for movement as a single unit over a second range of travel, toward and proximate to the cradle. When the upper and lower portions are coupled, the optical system has an optical path of a predetermined length extending from the platen surface, through the mirror arrangement and through the camera.

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 color scanner with a wedge shaped platen sequentially records opposing pages of a bound document positioned thereon using a single imaging station. The scanner includes a partially reflective mirror positioned between the wedge shaped platen. The two sides of the wedge shaped platen are illuminated with polarized light having angles orthogonal to each other. Polarized illuminators operate in combination with polarization analyzers positioned under the wedge shaped platen to sequentially image the opposing pages of the bound document. A controller insures that polarized light sources consisting of the three primary colors red, green, and blue, sequentially expose each opposing page of the bound document. The opposing pages of the bound document are focused through optics onto the single imaging station. In another embodiment, light polarized by analyzers positioned under the wedge shaped platen is filtered by a polarizer positioned in front of the focal optics before reaching the single imaging station. The controller first exposes one side of the platen and then the other to each of the three primary colors red, green, and blue. Digital representations of each primary color are combined to form a single composite image for each opposing page of the bound document. In one arrangement, the imaging station is a two-dimensional array of detectors which sense an image of a page of the bound document projected thereon. In another arrangement, the imaging station is a photoconductive belt which when exposed by the polarized light records a latent image thereon. In either arrangement, a one page imaging station records opposing pages of a bound document either electronically or on print media, one page at a time.

摘要： Selection of a trait may be received. A complex segment rule may be created that is usable to evaluate one or more qualification events. For example, the segment rule may be usable to evaluate a combined recency and frequency of the one or more qualification events. The qualification events may be based on collected network data associated with the plurality of visitors with each qualification event corresponding to a separate qualification of visitor according to the trait. The qualification events may be evaluated together according to the segment rule. For example, the combined recency and frequency of the one or more qualification events may be evaluated according to the segment rule. Evaluating the segment rule may include estimating a segment population size in real-time.
