Patent number: 11963691Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.Type: GrantFiled: December 21, 2020Date of Patent: April 23, 2024Assignee: Cilag GmbH InternationalInventors: Ryan M.

Patent number: 8844503Abstract: A fuel supply system and method of controlling fuel flow through a supply system is provided including a variable flow, i.e. speed, electric fuel transfer pump and a control system adapted to variably control the transfer pump based on fuel demand of the engine. The system provides improved transient response by providing the transfer pump with a feed forward speed/flow command based on engine fueling demand determined based on engine operating conditions. The transfer pump is controlled based on fuel demand not necessarily achieved yet by the high pressure pump and injectors. Therefore, this system controls the EFTP substantially simultaneously with controlling the high pressure pump and injectors to optimize fuel flow through the entire system ensuring the minimum required fuel flow is passing through the second the fuel filtration system, hence maximizing steady state fuel filtration efficiency, and minimizing surge effects on filtration efficiency.Type: GrantFiled: September 23, 2011Date of Patent: September 30, 2014Assignee: Cummins Intellectual Property, Inc.Inventors: Joseph A.
