Filed: 1994-08-11
Abstract: The device according to the first invention is adapted for producing the image of an object with the aid of radiation that either has been transmitted therethrough or excited therein or else scattered thereby. A lens is placed between a radiation source and a means for placing the object, or between the latter means and an image-forming means that registers the distribution of intensity of the radiation incident thereon (or else in both of these spaces), which lens is made according to the second invention and adapted for converting a flux of particles (that is, focusing a diverging or quasi -parallel radiation, forming a quasi-parallel radiation from a diverging one, monochromatization, spatial separation of different-energy particles contained in an original polychromatic flux, etc.). The lens comprising a set of radiation transfer channels (predominantly in the form of glass mono- or polycapillaries) is characterized in that the channels are arranged orderly across the lens cross-section with the obcervance of axial symmetry (i.e., mirror, central, or rotations1), whereby interference of the radiation emerging from the lens occurs. The channels may be grouped into modules 30 which are arranged orderly and symmetrically, each of the modules being in turn established by smaller modules 31 featuring the same number, shape, and mutual arrangement.
Patent CA-2171570-A1 (CA)
Inventor: LIM SWEE BOON
IPC: G06F9/45
Filed: 1996-03-12
Abstract: A system and method provides for variable target outputs from a compiler with only a single execution. The compiler includes a front end, a generic back end, and plurality of individual back ends that are dynamically loaded by the compiler during execution. The front end produces an abstract syntax tree which is then processed by the generic back end and the individual back ends to produce a number of back end trees, each adapted for a specific back end, and representative of the desired structure of the various target outputs, including target code files, or events. The generic back end traverses the abstract syntax tree, and on each node of the tree, invokes each back end that has a node of its back end tree attached thereto. The back end can then modify its own back end tree, and attach further back end nodes to other nodes of the abstract syntax tree. In turn the generic back end will invoke such added attached nodes, until all attached back end nodes on all the nodes of the abstract syntax tree have been processed. This results in completedback end trees for all of the back ends, requiring only a single pass of the front end to produce the abstract syntax tree. The individual back ends then process their respective back end trees to produce their target outputs. A look up operation is provided in the generic back end that returns one or more back end nodes in response to a request therefore specifying a node of the abstract syntax tree, and a family identification value of a back end node.

Title: Automatic determination of landscape scan in binary images
Inventor: KNOWLTON KENNETH C
IPC: G06V30/10
Filed: 1995-01-11
Abstract: A method and system for determining whether a digitized page is intended to be viewed in a first, portrait orientation or in a second, landscape orientation that is rotated with respect to the first orientation. The method includes a first step of examining an image of the digitized page on an image scanline by image scanline basis to detect occurences of graphic elements having heigths, widths, and aspect ratios that are within predetermined limits. The range-defining thresholds are determined to correspond to the expected dimensions of "charactersized" graphic objects. For each detected occurrence, the method determines a spatial relationship of the detected occurrence to other adjacently disposed objects. The method further operates, in accordance with a plurality of the determined spatial relationships, to declare the digitized page to have one of the first format and the second format. The step of determining operates to ascertain an amount of a spatial separation between the detected occurrence and an adjacent object on the same scanline and to an adjacent object on a succeeding scanline. The step of examining includes a step of forming, for each scanline, a list of spans of image pixels each having a predetermined value, and the step of determining a spatial relationship determines, for each span of the list, a distance to a next span on the same scanline, and for a last span of an image object, a distance to a first open span on a succeeding scanline. Each image object has an associated bounding box and a clear pedestal having a width that is a function of the width of the bounding box. The distance to the first span on a succeeding scanline defines a height of the pedestal.
