Patent number: 12003686Abstract: 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: GrantFiled: July 5, 2022Date of Patent: June 4, 2024Assignee: Lexmark International, Inc.Inventors: Stephen Porter Bush, Timothy John Rademacher, Christopher Alan Adkins

Patent number: 11484633Abstract: A multi-stage system for warming blood that enables safe and rapid blood transfusions in the field. The first stage of the system is a rapid blood warming device that heats blood quickly from cold storage to body temperature. This stage may use a high-energy power source, such as AC power, that is available in a facility such as a hospital. The second stage is a portable heated blood transport device into which heated blood bags are placed for transportation to a patient. This device keeps the blood bags warm using battery power. Because blood bags are pre-heated with the rapid warming device, the transport device can be lightweight and portable. An optional third stage is a transfusion temperature regulating device that boosts the final temperature of blood just before it enters the patient. All three devices may have sensors and controllers that maintain blood temperature within desired ranges.Type: GrantFiled: April 5, 2022Date of Patent: November 1, 2022Assignee: ARCHEMEDIC SOLUTIONS, LLCInventors: Glen Stephen Porter, Harry Ryan
