Patent number: 10866881Abstract: A method for firmware debug trace capture includes creating a hand-off block (“HOB”), capturing first debug trace statements during a boot sequence of a computer and writing the first debug trace statements to the HOB. A trace memory buffer can be created and the first debug trace statements can be copied from the HOB to the trace memory buffer. Second debug trace statements are captured during the boot sequence and appended to the trace memory buffer. In some configurations, the first debug trace statements can be written to the HOB during the pre-Extensible Firmware Interface initialization (“PEI”) phase of the boot sequence and the second debug trace statements can be written to the trace memory buffer during the driver execution (“DXE”) phase of the boot sequence.Type: GrantFiled: February 7, 2020Date of Patent: December 15, 2020Assignee: American Megatrends International, LLCInventors: Michael Harry Deiderich, III, Matthew Hoffmann, Thomas Gilreath

Patent number: 10838742Abstract: A firmware can include multiple features for multiple users enabled based on the presence of authenticated variables. When attempting to access functionality of a feature, the firmware will check for the presence of an authenticated variable corresponding to the feature. The authenticated variable for the feature may be installed by a user. The firmware may data to enable a feature that includes an authenticated variable for enabling the feature and an authenticated variable corresponding to an end-user of the firmware. If the firmware has access to the end-user authenticated variable, the feature authenticated variable is installed.Type: GrantFiled: September 2, 2019Date of Patent: November 17, 2020Assignee: American Megatrends International, LLCInventor: Matthew Hoffmann

Patent number: 10372661Abstract: Debug trace statements from a firmware are captured during a boot cycle of a computer executing the firmware. The debug trace statements are written to a motherboard's Serial Peripheral Interface (“SPI”) device. A microcontroller's SPI device receives the debug trace statements from the motherboard's SPI device, transforms the data format of the debug trace statements, and transmits the transformed debug trace statements over a serial communications port of the microcontroller.Type: GrantFiled: February 28, 2017Date of Patent: August 6, 2019Assignee: American Megatrends International, LLCInventor: Matthew Hoffmann

Patent number: 8179566Abstract: A method is provided for classifying a color printer gamut into a plurality of gamut subclasses including representing the color printer gamut as a composite of gamut classes wherein each gamut class is comprised of a subset of printer color separations; and, assigning selected spot color targets to determined ones of the gamut classes. The method further includes determining if the selected spot color target is located inside, or on-boundary, or outside of the gamut classes.Type: GrantFiled: December 19, 2007Date of Patent: May 15, 2012Assignee: Xerox CorporationInventors: Lalit Keshav Mestha, Alvaro Enrique Gil, Matthew Hoffmann

Publication number: 20080043271Abstract: This disclosure relates generally to methods and systems for color management in image/text printing or display systems, and more particularly to a system and method for automatically achieving spot color production through use of a plurality of gain matrices per spot color in determining spot color coordinates. Furthermore, this disclosure provides a means for mapping out-of-gamut target spot colors substantially near a boundary of the gamut of an image output device, such as a printer or display.Type: ApplicationFiled: October 4, 2007Publication date: February 21, 2008Inventors: Alvaro Gil, Lalit Mestha, Matthew Hoffmann
