Patent number: 8002182Abstract: A library terminal permits a user to execute a loan transaction without assistance. The library terminal (i) provides a visible scan line from a bar code reader indicating the correct positioning of the bar code on a circulating item, (ii) leads a user through a loan transaction, (iii) provides an explicit feedback to a user when an article has an improper position on the article receiving area, (iv) both checks out and checks in circulating items, (v) stores fonts in bit maps of screen displays instead of in a separate font memory, (vi) integrates a security marker reader, a printer, and a controller in the same housing, (vii) processes financial transactions related to the borrowing of circulating items, and/or (viii) displays actions for helping the user to correct errors in use of the terminal.Type: GrantFiled: April 3, 2009Date of Patent: August 23, 2011Assignee: 3M Innovative Properties CompanyInventors: Roger D. Larson, James E. Fergen, John E. Nelson, Thomas J. Brace, Michael J. Kieffer, John D. Yorkovich, Gerald L. Karel, Gerald G. Marsolek, Joseph E. Schwietz, Jr., Mitchell B. Grunes, Kathleen M.

Patent number: 7843311Abstract: A network communication and messaging protocol for use in a medical perfusion system, provides the rules which govern how, among other things, information and data is conveyed between the various devices which are connect to the network. The rules define the different types of messages that are used in conveying information and data, as well as the formatting for each of those message types. The various messages provide the ability to configure the perfusion system devices, establish links between the perfusion system devices, and convey various types of information and data, even when the main network controller is unavailable.Type: GrantFiled: March 4, 2009Date of Patent: November 30, 2010Assignee: Terumo Cardiovascular SystemsInventors: Richard M. Willems, Richard A. Nazarian, James R. Watts

Patent number: 6783328Abstract: Fluid pump control modes in a medical perfusion system include a Back Off Response Mode, a Flow Servo Mode, a Pressure Servo Mode, and a Master-Slave Servo Mode. In the Back Off Response Mode, pump's speed is decremented to a new speed when an excessive flow rate or pressure condition is detected. The new speed is maintained until an additional decrement is required or until the Back Off Response Mode is exited. In the Flow Servo Mode, a pump's speed is controlled to maintain a fluid flow rate indicated by a user as a setpoint. In the Pressure Servo Mode, a pump's speed is controlled to maintain a pressure indicated by the user as a setpoint. In the Master-Slave Servo Mode, a slave pump receives an indication of a master pump's speed, and the slave pump speed is controlled to maintain a specified percentage of the master pump's speed.Type: GrantFiled: February 21, 2002Date of Patent: August 31, 2004Assignee: Terumo Cardiovascular Systems CorporationInventors: Lori E. Lucke, Richard M. Willems, Richard A. Griewski
