Publication number: 20230401340Abstract: Values are received for one-time programmable (OTP) bits of an application-specific integrated circuit (ASIC) that are unprogrammed. The ASIC has one or multiple processors that are disabled. The OTP bits of the ASIC are programmed with the received values. The OTP bits after having been programmed govern which and whether instructions are executable by the ASIC. Future reprogramming of the OTP bits of the ASIC is disabled. In response to successful programming of the OTP bits and successful disabling of future reprogramming of the OTP bits, the processors of the ASIC are enabled.Type: ApplicationFiled: June 14, 2022Publication date: December 14, 2023Inventor: Gary M. Nobel

Patent number: 6870959Abstract: A method for automatic removal of vertical streaks involves a comparison between image data for a pixel and its neighbor pixels to determine whether the pixel is non-homogenous. In a preferred method, the comparison employs an adaptive threshold against which a difference between the pixel and its neighbor pixels is compared, with the adaptive threshold taking into account accumulative information pertaining to pixels generated by a common optical sensor element. A preferred method also includes the step of considering locations of non-homogenous pixels in the image to determine whether the image data associated with the non-homogenous pixels needs to be changed or modified. A preferred method also includes the step of associating the non-homogenous pixels with different image data.Type: GrantFiled: October 7, 1999Date of Patent: March 22, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Charles Chi Jia, Gary M. Nobel, Cindy Sansom, Howard Merrill, Daniel Wee

Patent number: 6618173Abstract: A method for automatic prevention of vertical streaks involves processing output signals from a plurality of photosites to determine what gain is appropriate for each output signal. An exemplary preferred method distinguishes between different types of output signals for which a first type of gain is appropriate and other output signals for which a second type of gain is appropriate. The first type of gain is a proportionate gain. The second type of gain is determined from at least one gain which is appropriate for output signals generated by neighbor photosites. The second type of gain is applied to the output signals when the processing indicates that a light-absorbing optical obstruction associated with the photosites generating the output signals appears to be positioned in an optical path of the photosites on or between a scan surface area over which an object to be imaged by the photosites is positioned and a calibration strip facing the scan area surface.Type: GrantFiled: October 7, 1999Date of Patent: September 9, 2003Assignee: Hewlett-Packard Development Company, LP.Inventors: Gary M. Nobel, Daniel Wee

Patent number: 6565190Abstract: In one embodiment of the invention, an inkjet printer selectively energizes ink ejection elements in a scanning printhead such that the top nozzles of the printhead do not always print the first line of text in a scan. In one embodiment, this is accomplished by occasionally aligning the bottommost nozzle in the printhead with the bottom of the last full line of text to be printed during the scan. The alignment of the printhead with respect to the lines of text to be printed is varied from page to page or varied at other intervals so that the top nozzles and bottom nozzles are used about equally. This will also cause more uniform wear of the middle nozzles. The more uniform wearing of the nozzles and ink ejection elements extends the life of the printhead.Type: GrantFiled: June 14, 1995Date of Patent: May 20, 2003Assignee: Hewlett-Packard CompanyInventors: Gary M. Nobel, Nicholas Nicoloff, Jr., Thomas M. Sabo, Clayton L. Holstun

Patent number: 5953028Abstract: A printer/plotter having a carriage for removably mounting a plurality of printheads, with one type of printhead such as a wider swath higher resolution black inkjet cartridge having one type of electrical interconnect and another type of printhead such as a narrower swath lower resolution color inkjet cartridge having a different type of electrical interconnect. The carriage includes differently configured flex-circuit conductive assemblies for each different type of electrical interconnect without having to change the datum configuration of the cartridges mounted in the carriage.Type: GrantFiled: October 24, 1997Date of Patent: September 14, 1999Assignee: Hewlett-Packard CompanyInventors: Gary M. Nobel, Majid Azmoon, Donald G. Harris

Patent number: 5949453Abstract: A printer with mixed base resolution capabilities, having a higher resolution monochrome component such as black and lower resolution components such as cyan, magenta and yellow. The different resolution components are integrated into the same printing mechanism for composite printing of higher resolution black and lower resolution color at the same time. For increased throughput, a higher resolution black printhead has a wider swath.Type: GrantFiled: October 29, 1993Date of Patent: September 7, 1999Assignee: Hewlett-Packard CompanyInventors: Donald G. Harris, Majid Azmoon, Gary M. Nobel

Patent number: 5796417Abstract: In a printer/plotter having a carriage for removably mounting one or more printhead cartridges, multiple pairs of aligned electrical interconnect pads provide signal transmission between printhead circuits and corresponding circuits on the carriage. A compliant foam material is positioned on the carriage to provide increased pressure for assuring conductivity across each interconnect pad junction. In a preferred embodiment, a thick block of compliant foam material having a flat upper surface is installed on the carriage for each printhead cartridge, and is positioned in an elongated rigid cavity of the carriage to push against the peripheral base portions of more than fifty dome-shaped copper interconnect pads which are densely packed on the flexible circuit.Type: GrantFiled: March 6, 1995Date of Patent: August 18, 1998Assignee: Hewlett-Packard CompanyInventor: Gary M. Nobel

Patent number: 5533904Abstract: An improved interconnect system for an inkjet printer. The inventive interconnect system includes first and second unitary flexible circuits having first and second sets of contacts, respectively, for providing first and second electrical interconnections, respectively. The first and second flexible circuits are aligned and retained so that contacts thereon engage corresponding contacts disposed on a rigid support. In a specific implementation, the first flexible circuit is aligned by a first set of pins arranged along a first axis and the flexible circuit is aligned by a second set of pins arranged along a second axis, perpendicular to the first axis. This arrangement allows for the alignment and mounting of two flexible circuits on a single printer carriage without a substantial increase in the width thereof.Type: GrantFiled: April 28, 1994Date of Patent: July 9, 1996Assignee: Hewlett-Packard CompanyInventors: Gary M. Nobel, Arthur K. Wilson, Patricia S. Brown, Jason R. Arbeiter

Patent number: 5504513Abstract: An inkjet printer (10) has a movable carriage (12) supported above an ink-receiving medium by a rail (14) defining a carriage axis. A cartridge holder (16) is mounted on the carriage and having at least one cartridge compartment (18), each of the at least one compartment having a compliant compartment wall (82). Each compartment is providing with an opening at one end (19) of the carriage floor for receiving the snout (72) of an ink jet printer cartridge (20) on which is mounted a nozzle plate with more that one nozzle for depositing ink onto the ink-receiving medium. Each compartment is also provided with equalizing structure for maintaining the cartridge substantially perpendicular to the carriage axis when the compliant compartment wall is deflected by a spring at the middle of the compartment forcing two datum surfaces on the cartridge against front and rear supporting surfaces on the compartment wall. The equalizing structure preferably includes a second opening (21) at the other end of the floor.Type: GrantFiled: April 25, 1994Date of Patent: April 2, 1996Assignee: Hewlett-Packard CompanyInventors: Gary M.
