Publication number: 20220252018Abstract: The present disclosure relates to a method for controlling pressure of an engine, including a controller structured to implement the method and an engine system including the controller. More specifically, the present disclosure relates to a method based on a mass balance analysis of a fuel system to determine how much mass needs to be pumped to maintain or achieve a certain pressure for the engine. In some embodiments, the method analyzes how much mass can be pumped by each pumping event based on current engine conditions. The analysis is performed over the smallest repeatable pump events and cylinder events cycle, or “subcycle,” based on the number of pump events and cylinder events for a given engine configuration.Type: ApplicationFiled: August 2, 2019Publication date: August 11, 2022Applicant: Cummins Inc.Inventors: Paul Peavler, Donald J.

Patent number: 11243867Abstract: Techniques for modifying a user interface in which respective elements are presented if the criteria for those elements are satisfied include receiving criteria and element characteristics for a new or modified user interface element. The criteria for the new or modified element are compared to criteria for existing elements to determine other elements that could be presented contemporaneously if a request satisfying multiple sets of criteria is received. For each element with corresponding criteria, the characteristics of the element are compared to those of the new or modified user interface element to determine whether the sets of characteristics are mutually exclusive. If the characteristics are mutually exclusive, a conflict exists and information regarding the author of the existing element and the goal or rationale associated with the element may be provided to the user attempting to modify the user interface.Type: GrantFiled: December 7, 2018Date of Patent: February 8, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Michael Carey Wexler, Vignesh Lakshminarayanan, Vinod Murali, Leonardo Maia Carneiro De Novaes, Gerasimos Arvanitis, Calvin Daniel Freitas

Patent number: 11037098Abstract: Examples provide a system for managing disposition of returned items and/or items having damaged packaging. An item is identified based on item scan data. Item data associated with the item and condition data describing the condition of the item, including describing defects in the item or item packaging. The system identifies a set of applicable disposition options customized for the item. The system recommends a disposition from the set of applicable disposition options to assist the user with selection of an appropriate disposition. The disposition can include a price markdown, donation of the item, return of the item to a supplier, and so forth. If the selected option is a markdown of the item, the item disposition component generates a markdown amount for the selected item which avoids loss for the item. The item disposition system generates a label for the item including details of the selected disposition.Type: GrantFiled: March 14, 2019Date of Patent: June 15, 2021Assignee: Walmart Apollo, LLCInventors: Tim Wicks, John Sokolsky, Joshua Chaney, Michael Carey, Russell Dylan Lane, Rajiv Jivan, Roger Paredes, Chelsea Burns, John E.

Publication number: 20210157963Abstract: A non-limiting example of a computer-implemented method for error injection includes executing a pre-silicon operation on a simulated chip verifying that a plurality of latches from a timing simulation set error checkers when run against a manufacturing test suite in order to generate a cross-reference file containing latch entries in a table. It executes a first post-silicon operation on a hardware chip based on the simulated chip to determine empirically that timing latches from logic built-in self tests (“LBIST”) trigger the same error checkers set by the plurality of latches verified in the simulated chip. The method updates the cross-reference file based on the results of the determination. The method executes a second post-silicon operation on the hardware chip to improve chip frequency by working around functional checkers using the cross-reference file and updating the cross-reference file based on the results of the improving.Type: ApplicationFiled: November 22, 2019Publication date: May 27, 2021Inventors: Sean Michael Carey, Richard Frank Rizzolo, Bodo Hoppe, Divya Kumudprakash Joshi, Paul Jacob Logsdon, Sreekala Anandavally, WILLIAM RURIK

Patent number: 10956659Abstract: Multiple webpages are used to generate a template that includes portions of webpage code or other instructions common to the webpages, and a view model for each webpage that indicates instructions that may be added to the template to reconstruct the webpage. A first webpage and a second webpage are analyzed to generate a first set of tokens that represent instructions for the first webpage and a second set of tokens that represent instructions for the second webpage. The sets of tokens are compared to determine matching and differing instructions between the webpages. A template is generated that includes the matching portions of instructions and placeholders at locations associated with differences. A view model for each webpage is generated that includes a value for each placeholder, the value being the instructions that may be added to the template at the location of the placeholder to reconstruct the webpage.Type: GrantFiled: December 9, 2019Date of Patent: March 23, 2021Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Michael Carey Wexler, Erik Anders Karulf
