Publication number: 20230085110Abstract: An implantable medical device comprises a control circuit and a memory. The memory is operably coupled to the control circuit. The memory comprises instructions that, when executed by the control circuit, cause the control circuit to monitor an output of at least one comparator, the output of the at least one comparator being responsive to a cardiac signal of a patient. The instructions further cause the control circuit to automatically adjust a gain level applied to the cardiac signal over time based on the monitored output of the at least one comparator.Type: ApplicationFiled: September 10, 2021Publication date: March 16, 2023Applicant: LivaNova USA, Inc.Inventor: Robert Alan Adkins

Publication number: 20220337724Abstract: A supply item has toner for use in an imaging device. A chip has memory storing quanta indicating allowed usage of the supply item over its lifetime and a multiplier correlating the quanta to toner mass. The imaging device requires quanta to conduct imaging operations and loads the quanta and multiplier by way of a certificate stored in the memory. The imaging device retrieves quanta from the chip over time and both devices keep tally. Initialization between the supply item and imaging device includes providing encrypted and unencrypted instances of firmware versions and certificates from the supply item that the imaging device can compare for security. Alternatively, the supply item defines a fuser assembly, imaging unit, intermediate transfer member, or other component installed for use in the imaging device.Type: ApplicationFiled: July 5, 2022Publication date: October 20, 2022Inventors: STEPHEN PORTER BUSH, TIMOTHY JOHN RADEMACHER, CHRISTOHPER ALAN ADKINS

Patent number: 9959493Abstract: Methods for authenticating printer supply items using revocation lists are disclosed. Revocation lists are updated using DNSSEC to communicate between a printer and a DNS name server. A first domain name is created containing a request for a challenge to an authentication module and sent to the DNS name server. A second domain name is created containing a response to the challenge and sent to the DNS name server. The DNS name server indicates success or failure, which is used to authenticate the printer supply item. Other systems and methods are disclosed.Type: GrantFiled: March 8, 2016Date of Patent: May 1, 2018Assignee: Lexmark international Inc.Inventors: Christopher Alan Adkins, James Ronald Booth, Matthew David Clarke, Graydon Randall Dodson, Joshua Scott Potter

Patent number: 9569631Abstract: A method and apparatus for configuring an electronics device. The method includes receiving, by the electronics device, a request for a command to perform a predetermined operation by the electronics device and sending the command in response to receiving the request. The electronics device then receives a signature based upon the command, whereupon the electronics device verifies the signature by the electronics device and, following an affirmative verification, executes the command for performing the predetermined operation. In this way, the electronics device may be reconfigured remotely without knowledge of the particular command for performing the predetermined operation by the electronics device.Type: GrantFiled: May 31, 2011Date of Patent: February 14, 2017Assignee: Lexmark International, Inc.Inventors: Christopher Alan Adkins, Stephen Porter Bush, Mark Walter Fagan, Duane Edward Norris, Douglas Keith Perterson, Jr., Thomas James Wack, Gregory Scott Woods

Patent number: 9535852Abstract: Slave device circuitry, including processing circuitry which is configured to determine a new session identification value; determine a seed value using a secure hash algorithm on a previously determined seed value; determine a slave number from using the secure hash algorithm on the new session identification value, the determined seed value, and a serial number of the slave device associated with the slave device circuitry; receive a host number from the host imaging apparatus and calculate a session key using a hash-based algorithm computation on the host number, the slave number, the new session identification value, and a stored encryption key. The session key has a first portion for performing encryption and decryption operations on data to be transmitted and data received by the slave device, respectively, and a second portion for generating a new address value of the slave device for communicating with the host.Type: GrantFiled: December 9, 2015Date of Patent: January 3, 2017Assignee: Lexmark International, Inc.Inventors: Christopher Alan Adkins, Timothy John Rademacher
