Patent number: 7050195Abstract: A method of, and apparatus for, printing information on a hardcopy medium includes the acceptance of data representing a first information and the acceptance of data representing a second information. Second information is printed in regions on the medium where first information data is not printed. Second information data is encoded into a grayscale or color data representation such that necessary or maximum data density is achieved. First information is printed using black (K) ink (or alternatively using a different color gamut than that used for printing the second information) such that first information can be filtered out in a straightforward manner upon scanning of the printed medium by a digital scanning apparatus, and second information can then be recovered and utilized to advantage.Type: GrantFiled: April 20, 2000Date of Patent: May 23, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventor: Michael J. Jones

Patent number: 6711806Abstract: An inkjet printing device employs an inkjet printhead with a plurality of drop generators to eject drops of ink. Each drop generator includes a planar heater resistor, comprising three segments. Two of the segments are disposed on either side of the third segment and provide a reduced thermal loss for the third segment. This reduced thermal loss and other features cause a controlled nucleation point to occur over the third segment even though the two segments on either side will create ink vapor bubbles of variable size depending upon the applied energy.Type: GrantFiled: March 4, 2002Date of Patent: March 30, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventor: Donald W. Schulte

Patent number: 6697089Abstract: In order that an improved communications interface between a human and a computer be provided, the interface to the computer program is directed to accommodate the variabilities of human communication rather than accommodate the rigid structure of syntax, grammar, and semantics normally used in communications with a computer. A computer program human interaction dialog is customized by detecting a need of the computer program to present knowledge to a user in human perceptible form and providing options of grammar and semantics for describing the knowledge. These options of grammar and semantics are presented as a choice to the user. The user's choice is saved for later use when the knowledge itself is presented.Type: GrantFiled: April 18, 2000Date of Patent: February 24, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventor: Shane A. Bryan

Patent number: 6673160Abstract: In order that sensitive structures of inkjet printing mechanisms be cleaned without damaging these structures, a cleaning sheet and a process of using the sheet has been created. Debris and dried ink is removed from print cartridges and their carriage using a cleaning sheet having two strips of material spaced with a napped surface disposed longitudinally between the side edges and spaced apart from each other. By controlling the distance the strips are spaced from the sheet feed edge of the cleaning sheet, the print cartridges can be placed adjacent the strips for scrubbing against the strips without resulting in a media jam in the printer due to the increased thickness of the cleaning sheet.Type: GrantFiled: February 5, 2001Date of Patent: January 6, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ralph L Stathem, John R. Carnes, Kevin Almen, Babak Honaryar, Kris M. English

Patent number: 6594899Abstract: An inkjet printing device employs an inkjet printhead with a plurality of drop generators to eject drops of ink. Each drop generator includes a planar heater resistor, a protection layer having a first heating surface on the heater resistor and a second heating surface entirely surrounding the first heater surface on the heater resistor, and an ink ejection nozzle. The drop generator vaporizes ink at the first heating surface and ejects a drop of ink of a first mass from the nozzle when a first range of energies is applied to the heater resistor. The drop generator vaporizes ink at the first heating surface and the second heating surface and ejects a drop of ink of a second mass from the nozzle when a second range of energies is applied to the heater resistor.Type: GrantFiled: February 14, 2001Date of Patent: July 22, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Robert C. Maze, Todd A. Cleland, Arun K. Agarwal, Mark A. Buonanno

Patent number: 6592205Abstract: A printhead is formed from a plurality of ink ejectors mounted on an inner surface of a rigid substrate while protruding through holes provided in the substrate. Electrical contact is provided on a surface of the ink ejectors common with the ink ejecting nozzles thereby avoiding vias to another surface. The rigid substrate provides a conducting layer on its inner surface such that the ink ejectors may be connected thereto with solder reflow techniques.Type: GrantFiled: August 7, 2001Date of Patent: July 15, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Timothy Beerling, James W Pearson, Antonio Cruz-Uribe, Melissa D.

Patent number: 6557974Abstract: A printhead for an inkjet printer employs non-circular orifices, such as oval or parallelogram, at the surface of the orifice plate to increase the restoring force of the ink meniscus. The reduced tail and diminished spray of an ink droplet expelled from the non-circular orifice results in improved edge roughness and improved quality of print.Type: GrantFiled: October 25, 1995Date of Patent: May 6, 2003Assignee: Hewlett-Packard CompanyInventor: Timothy L.

Patent number: 6540325Abstract: An inkjet printing device is arranged to employ a first set of multiple nozzle drop generators activated by a first address signal and a second set of multiple nozzle drop generators activated by a second address signal. The multiple nozzles of each drop generator of the first set are arranged in a predetermined geometric pattern, each of which encompasses at least one nozzle of a drop generator of the second set. The ink ejectors of one drop generator of the first drop generator set are arranged in subgroups, one subgroup of which shares a switched power return with one subgroup of ink ejectors of one drop generator of the second drop generator set.Type: GrantFiled: March 6, 2001Date of Patent: April 1, 2003Assignee: Hewlett-Packard CompanyInventors: Naoto A.

Patent number: 6489084Abstract: The photoresist barrier layer of an inkjet printer printhead is processed to enable channels narrower than a predetermined width in the barrier layer to be created without blockage. Relatively large volumes of photoresist which form a wall of the channel are exposed to a partial exposure of electromagnetic radiation to yield a reduced concentration of photoresist barrier layer in the large volume.Type: GrantFiled: September 18, 2000Date of Patent: December 3, 2002Assignee: Hewlett-Packard CompanyInventors: David Pidwerbecki, Gerald T.
