Patent number: 11918240Abstract: A clot removal system comprises a catheter, a vacuum source, and a controller. The catheter comprises a proximal end, a distal end, and controller operating parameters and defines a lumen configured to be filled with a liquid column having a proximal portion. The vacuum source is configured to supply vacuum. The controller is configured to carry out a control pattern of turning on and off the vacuum based upon the controller operating parameters and is configured to receive the controller operating parameters in an automatic response to the catheter being operatively connected to at least one of the vacuum source and the controller and, responsive to the connection, to carry out the control pattern to change a level of vacuum at the distal end of the catheter.Type: GrantFiled: January 26, 2022Date of Patent: March 5, 2024Assignee: RapidPulse, Inc.Inventors: Derek Dee Deville, Matthew A. Palmer, William T. Bales, M. Sean McBrayer, Eric Petersen, Richard Cartledge, Thomas O. Bales, Jr., Carlos Rivera

Patent number: 9845751Abstract: Methods and systems are provided for improving combustion stability, in particular during transient operations such as tip-out to lower load conditions, when EGR is being purged. Until a desired LP-EGR rate is achieved, fuel may be delivered as a split injection with at least an intake stroke injection and a compression stroke injection. Subsequently, single fuel injection may be resumed.Type: GrantFiled: January 27, 2017Date of Patent: December 19, 2017Assignee: Ford Global Technologies, LLCInventors: Steven Wooldridge, Gopichandra Surnilla, Jianwen James Yi, Brad Alan Boyer, James Alfred Hilditch, Michael Howard Shelby, Benjamin Richard Petersen

Patent number: 9840976Abstract: Methods and systems are provided for improving engine knock tolerance, in particular when rapidly ramping in LP-EGR from low levels of EGR. Until a desired LP-EGR rate is achieved, fuel may be delivered as a split injection with at least an intake stroke injection and a compression stroke injection to compensate for the transport delay in EGR filling the intake system. Subsequently, single fuel injection may be resumed.Type: GrantFiled: May 8, 2017Date of Patent: December 12, 2017Assignee: Ford Global Technologies, LLCInventors: Steven Wooldridge, Gopichandra Surnilla, Brad Alan Boyer, James Alfred Hilditch, Michael Howard Shelby, Chris Paul Glugla, Benjamin Richard Petersen
