Patent number: 6955073Abstract: A method of determining the accuracy of a pressure sensor in a surgical console is disclosed. The method involves actuating a linear actuator so that its plunger is linearly displaced a pre-defined amount, and measuring the force exerted by the plunger on a non-compliant member. The accuracy of the linear actuator and the plunger are determined by comparing the force measured in the measuring step to a pre-defined force.Type: GrantFiled: February 28, 2003Date of Patent: October 18, 2005Assignee: Alcon, Inc.Inventors: Michael D. Morgan, Gary P. Sorensen

Patent number: 6868720Abstract: A method of determining the accuracy of a pressure sensor in a surgical cassette is disclosed. The method involves displacing a diaphragm of the sensor a pre-defined amount of displacement, and measuring the force exerted on the diaphragm by the displacing step. The accuracy of the pressure sensor is determined by comparing the force measured in the measuring step to a pre-defined force for the pre-defined amount of displacement.Type: GrantFiled: February 28, 2003Date of Patent: March 22, 2005Assignee: Alcon, Inc.Inventors: Donn D. Lobdell, Michael D. Morgan

Publication number: 20040253129Abstract: A surgical system having a cassette with an aspirant vent line that permits a fluidic connection between the inlet to a aspirant pump and the outlet of the aspirant pump through a vent valve. When the aspiration vent valve is open, fluid flows from the pump outlet into the pump inlet, thereby releasing any pressure within the pump inlet. Such a system does not require a second source of irrigation fluid, minimizes pressure surges into the irrigation fluid line and does not affect the fluidic performance of the aspiration system.Type: ApplicationFiled: July 15, 2004Publication date: December 16, 2004Inventors: Gary P. Sorensen, Michael D. Morgan

Patent number: 6783345Abstract: The invention provides methods, systems, and devices for installing barriers in openings or gaps in or between structures such as walls, ceilings, and floors. At least one barrier molding bag is positioned in the hole or gap, and a flowable firestop material that is preferably operative to cure or harden, such as a hydratable cementitious slurry, is introduced into the bag to create a barrier in the hole or gap.Type: GrantFiled: May 20, 2002Date of Patent: August 31, 2004Assignee: W.R. Grace & Co.-ConnInventors: Michael D. Morgan, Xiudong Sun, Laura A. Tennenhouse, Robert A. Wiercinski, Benita Dair, Antonio J. Aldykiewicz, Jr., Leon Bablouzian, Lawrence Shapiro, William J.

Patent number: 6780230Abstract: Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate.Type: GrantFiled: January 11, 2002Date of Patent: August 24, 2004Assignee: W.R. Grace & Co. -Conn.Inventors: Dennis M. Hilton, Michael D. Morgan, Robert Paul, Karl D. Taub, Robert S. Young, Ricky N. Bastarache

Patent number: 6740074Abstract: A surgical system having a cassette with an aspirant collection chamber and an aspiration vent line that draws fluid from the aspirant collection chamber. The pressure within the collection chamber is maintained near ambient so that when the aspiration vent line is open, fluid flows from the collection chamber and into the aspiration line. Such a system does not require a second source of irrigation fluid, minimizes pressure surges into the irrigation fluid line and does not affect the fluidic performance of the aspiration system. In addition, various vent pressures can be achieved by varying the vertical position of the reservoir relative to the aspiration line.Type: GrantFiled: August 9, 2001Date of Patent: May 25, 2004Assignee: Alcon, Inc.Inventors: Michael D. Morgan, Gary P. Sorensen
