Abstract: A digital form scoring system that does not require that the targets on the marked form be digitally captured with a drop-out scanner. This is accomplished by locating each target, and in the mark interpretation logic, sensing an area within the outline of the target, then digitally removing all or most of thin lines of print that form a symbol or character within the outline, and removing the shading in the background, before applying the logic that determines whether a region of dark gray scale values in the sensing area should be considered a valid mark entered by the subject.

Abstract: A document image scanner; a camera having a field of view, for sensing differentiated information areas on each physical document as the physical document is transported; an image processing system associated with the camera, for producing a virtual image data file from the differentiated information areas sensed by the camera; sensors for determining the position of the physical document relative to the camera field of view; of electro-mechanical devices for actuating the transporter; and a data interface controller for receiving data from the sensors and controlling the electro-mechanical devices. A communications link is provided between the data interface controller and the image processing system for synchronization by the data interface controller, of the physical document as conveyed and the virtual document image captured by the image processing system.

Abstract: In a broad aspect of the invention, the master printed form is scanned and processed according to a forms definition program to produce a virtual form file comprising a virtual layout of the significant regions such as bubble targets of printed material on the form, on a virtual coordinate system. Production forms that have been marked by subjects (e.g., students, voters, survey respondents, etc.), are then scanned to produce a marked form file of gray scale darkness values for each marked form. The marked form file and the virtual form file, are compared and processed to determine the location and spatial relationships of the marks on the marked form, in relation to the virtual coordinate system of the virtual form. The raw scan of each marked form is also processed to determine whether darkened areas on the marked form image should be interpreted as intentional responses from the subject, at the virtual coordinates where targets are located on the virtual form.

Abstract: A method for preparing fibronectin and further a process for treating cancer resections which prevents or reduces local recurrences of cancer in procedures in which cancerous tissues are resected comprising the steps of: mixing a pharmaceutical fibronectin with a suspending medium to provide a fibronectin composition; applying the fibronectin composition to a surgically exposed tissue from the cancer resection; and closing the surgically exposed tissue using conventional suturing techniques.

Abstract: The processing of documents evidencing business transactions is enhanced by optically scanning and imaging only specific areas of interest, amount fields for example, and simultaneously storing the imaged amount fields in two separate files. Subsequently, only those images which correspond to a dollar amount which has not been successfully read will initially be displayed to an operator for key entry of the amount. A balancing procedure is performed and if a comparison of the total of the individual imaged amounts equals the total entered on a summary document further key entry of amounts will be unnecessary.
