摘要:
An incoherent, optically uncoupled laser array for an electro-optic line modulator or a line printer or the like and comprising a plurality of spatial laser emitters characterized by having high power density and a uniform far field emission pattern. Structural means is provided in the array to permit the spacing of the emitters sufficiently close to provide a uniform far field emission pattern without permitting phaselocking between adjacent emitters of the array. The structural means may comprise geometric lateral and diagonal displacement of adjacent optical cavities of the laser elements. Alternatively, the structural means may comprise a plurality of spatially disposed isolation regions extending across the laser array and extending into the laser array a distance sufficient to optically isolate the optical cavities of the laser elements from one another and prevent optical coupling between adjacent laser elements. The spatial isolation regions may be formed into the fabricated laser array using impurity induced disordering (IID).

A method of adjusting a document configuration includes the steps of generating a set of document configuration constraints that define an acceptable range of change in the look and feel of a document, the configuration of which is to be adjusted. The method includes modifying the document configuration while satisfying the set of document configuration constraints to minimize the change in the look and feel of the document.

A system for the transaction of transactional amounts when using merchantable content on a medium includes a clearinghouse, an apparatus having a medium handier, a merchantable content receiver, a medium identifier, a content identifier, a medium use mechanism, and a transmitter. The medium handler accepts the medium and the merchantable content receiver accepts the merchantable content. The medium identifier reads a first identifier from the medium. The content identifier reads a second identifier from the merchantable content. The medium use mechanism incorporates and uses the merchantable content with the medium. The transmitter sends the first and second identifiers to the clearinghouse. The clearinghouse has a first account for a medium provider referenced by the first identifier and a second account for the content provider referenced by the second identifier. The clearinghouse further includes an account manager for transferring a royalty amount from the first account to the second account when the first and second identifiers are received.
摘要:
A method and apparatus for detection of highlighted regions of a document. A document containing highlighted regions is scanned using a gray scale scanner. Morphology and threshold reduction techniques are used to separate highlighted and non-highlighted portions of the document. Having separated the highlighted and non-highlighted portions, optical character recognition (OCR) techniques can then be used to extract text from the highlighted regions.
摘要:
Machine readable electronic domain definitions of part or all of the electronic domain descriptions of hardcopy documents and/or of part or all of the transforms that are performed to produce and reproduce such hardcopies documents are encoded in codes that are printed on such documents, thereby permitting the electronic domain descriptions of such documents and/or such transforms to be recovered more robustly and reliably when the information carried by such documents is transformed from the hardcopy domain to the electronic domain.
