Simple and inexpensive high-capacity output catch tray for document production machines

Granted: October 2, 2003
Application Number: 20030185614
The invention is relates to a simple, inexpensive high capacity output catch tray for copiers and other document production machines. The output tray automatically increases in capacity as the stack of copies in it accumulates, without external power source or control, while maintaining a relatively constant elevation relative to the copier output port, and automatically returns to its original position when partially or completely unloaded.

Methods and systems for the provision of printing services

Granted: September 25, 2003
Application Number: 20030182438
The present invention relates to methods and systems for providing printing services over a communications network. In particular, the present invention enables a user to obtain print jobs at an unspecified location which may be remote from the source of the print job. A spooling server is used to store a print job received via the network from a print job source. A printer polling device is capable of polling the spooling server via the network to identify whether any print jobs…

Process and system for mixed page imposition

Granted: January 30, 2003
Application Number: 20030020956
A process for formatting printable information orders selected data objects, document pages or images, to create a new document, where pages may be of uniform dimension and page orientation or varying in one or both of dimension and page orientation. Groups of pages are imposed on sheets so that the sequence of the printed pages matches the page sequence of the created document after post-printing processing. A method of imposing the differently shaped and sized printable pages on sheets…

Methods and apparatus for correcting spectral color measurements

Granted: November 7, 2002
Application Number: 20020165684
Methods and apparatus are disclosed for correcting spectral measurements, such as are obtained by a spectrophotometer for measuring color. A single matrix is used that operates on a raw measurement vector (spectrum) to obtain a corrected spectrum. The matrix may embody a transform that minimizes the difference between the corrected spectra and a set of reference spectra. The difference may be characterized by a set of basis function weighting vectors which are then used to build the…

Digital image compression with spatially varying quality levels determined by identifying areas of interest

Granted: October 3, 2002
Application Number: 20020141650
Methods and systems for compression of digital images (still or motion sequences) are provided wherein predetermined criteria may be used to identify a plurality of areas of interest in the image, and each area of interest is encoded with a corresponding quality level (Q-factor). In particular, the predetermined criteria may be derived from measurements of where a viewing audience is focusing their gaze (area of interest). In addition, the predetermined criteria may be used to create…
