Abstract: To reduce the trade-off between image quality and marking speed, high-resolution data for an image is evaluated, and an output value is created based on the evaluation of the high-resolution data. The output value has a larger output spacing than the high-resolution data, and approximates an edge of a solid defined by the high-resolution data, but within an output area defined by the larger output spacing.

Abstract: A management apparatus which includes: a receiving unit that receives first authorization information for a first document that is already issued and contains document identification information identifying at least one document for which it is possible to issue authorization information and an issuance request requesting that second authorization information for a second document be issued; a verifying unit that verifies authenticity of the first authorization information that is received by the receiving unit; a checking unit that, in a case where the authenticity of the first authorization information is verified, checks whether or not document identification information identifying the second document is included in the first authorization information; and an issuing unit that, in a case where the document identification information identifying the second document is included in the first authorization information, issues the second authorization information.
Abstract: In the illustrated embodiment of the invention a scanning system is provided for scanning a chargeable surface for latent image detection. The chargeable surface is charged to a first potential, and a scanner probe is charged to a second potential within a predetermined potential difference from the first potential. The scanner probe is oscillated at a selected frequency and reads or measures the oscillation current that is induced from the oscillation and detects any latent images or other electrostatic distributions on the chargeable surface. A processor processes the probe measurements for determining the potential of a latent image on the chargeable surface based on the scanner probe readings.

Abstract: A machine, such as a phase change or solid ink printing apparatus, has at least one multiple supply unit in the form of an ink stick disposed therein. The ink stick has an electronically-readable memory device associated therewith, and the memory device has stored therein electronic data related to the ink stick and readable by the machine. The memory device is attached to the ink stick and removed before the ink stick is used for printing in the machine. In another aspect, the memory device is attached to a container for the ink stick. The container is a cartridge for use in the machine, or a container for packaging the ink stick. The machine may include a coupler configured to read electronic data from the memory device while the memory device is positioned external to the printing apparatus, thus allowing the machine to verify the suitability of the ink stick before it is installed in the machine.

Abstract: An apparatus and method facilitate combined query based searching with serendipitous browsing in a multimedia collection. A user selects objects to label from a local map, which may include representations of objects retrieved from the collection as being responsive to a text or image base query. The text and image portions of the object can be independently labeled. Unlabeled objects are scored and ranked based on the applied labels of labeled objects, which may take into account cross-media pseudo-relevance and user selectable (or default) parameters, such as a forgetting factor, which tends to place greater weight on more recently labeled objects, and a modality parameter, which laces greater weight on the modality (text, image, or hybrid) currently selected by the user. The local map is modified, based on the ranking, optionally after reranking of objects to improve the diversity of the displayed objects.
