Abstract: A computer readable medium stores a program causing a computer to execute a key generating processing. The computer generates a signatory private key which is used in an electronic signature, a signatory public key, a signatory public key certificate, a certification public key which is used when recording the signatory private key in a PKI card and a certification private key, transmits the certification private key to the PKI card via a secure communication path, and transmits an encoded signatory key obtained by encoding the signatory public key certificate and the signatory private key using the certification public key to the PKI card via the secure communication path or a non-secure communication path.
Abstract: A composition that may be used to form an electronic circuit element includes metal nanoparticles in a metal nanoparticle solution, at least a low-polarity additive and a solvent. The low-polarity additive is either a styrenated terpene resin or a polyterpene resin. The composition may be used to form conductive features on a substrate by depositing the composition onto a substrate, and heating the deposited composition on the substrate to a temperature from about 80° C. to about 200° C. to form conductive features on the substrate.

Abstract: A method and system feeds sheets through a media path in a process direction and moves a laterally movable sheet registration carriage (positioned within the media path) in a lateral direction perpendicular to the process direction. It determines the lateral error of the sheets within the media path before the sheets enter the sheet registration carriage, using first sensors positioned within the media path. This allows the sheet registration carriage to be moved to a variable lateral starting position (as opposed to a consistent reset position or centered reset position) before the sheets enter the sheet registration carriage based on the error of the sheets as determined by the first sensors. The error can be the amount of lateral error, or simply can be a classification of lateral error (right error, left error, etc.).

Abstract: An interrupt control apparatus includes: an interrupt request supply unit that supplies interrupt request information; a processing unit that performs interrupt processing based on the interrupt request information supplied by the interrupt request supply unit; and a time measuring unit that is used to measure an elapse of a predefined time period from a time point when the interrupt request supply unit starts to supply the interrupt request information, wherein: even if new interrupt cause information is stored during the time when the time measuring unit is measuring the elapse of the predefined time period, the interrupt request supply unit does not supply interrupt request information based on the new interrupt cause information to the processing unit; and after the elapsed time measured by the time measuring unit reaches the predefined time period, the interrupt request supply unit supplies the interrupt request information to the processing unit.
Abstract: A system evaluates image quality in an image generating system in the presence of digital image noise and/or missing jets. The system includes a test pattern generator configured to generate a test pattern on an image substrate, an image capture device configured to generate a digital image of the generated test pattern on the image substrate, an image evaluator configured to process the digital image and generate a solution for an over-determined matrix of equations formed from differential distance measurements obtained with reference to a jet in the digital image by minimizing the root-mean-square (RMS) of residual errors corresponding to the matrix, and a controller configured to generate a correction parameter from the generated solution and to apply the correction parameter to the jet used for the used for the differential distance measurements.

Abstract: A history management apparatus includes: a storage unit that stores history information of image processing which contains set-membership information containing pieces of document identification information of an input document and an output document, and an image of at least one of the input document and the output document as history information; and a notification unit that, when history information in which a surveillance target element is contained in an image of an input document or an image of an output document is detected from the storage unit, notifies a notified party of such as the detected history information. When the surveillance target element is not contained in both of the images in the history information, and it is identified that at least one of ancestral documents of the input document has the surveillance target element, the notification unit notifies the notified party of the history information.

Abstract: An illuminator system includes an illuminator array positioned adjacent to an image bearing surface, a light diffuser, and a linear sensor array. The light diffuser includes a plurality of rounded lenslets having convex or concave configuration positioned between the illuminator array and the image bearing surface. The rounded lenslets are positioned with respect to the illuminator array to receive the light beams emitted by the illuminator elements and to diffuse the light beams being transmitted to the image bearing surface in the linear direction of the illuminator array. Each of the rounded lenslets has a textured surface with a plurality of indentations. Each of the indentations is configured to randomly diffuse the light beams being transmitted to the image bearing surface.
