Publication number: 20120025995Abstract: An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. A method, system, and an article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided. The electrical current to an infusion pump is measured. Based on a series of measurements of one or more variables, the infusion pump detects whether there is an occlusion in the system.Type: ApplicationFiled: October 5, 2011Publication date: February 2, 2012Applicant: MEDTRONIC MINIMED, INC.Inventors: SHELDON B. MOBERG, Ian B. Hanson, Cary D. Talbot

Patent number: 8060232Abstract: Methods and computer storage media provide for the installation of potted inserts and installation validation. According to embodiments described herein, an insert is placed within an insert aperture of a panel or other structure. Potting compound is injected into a potting cavity surrounding the insert through a fill hole in the insert until potting compound overflows from another fill hole. The installation is validated by applying a force to the installed insert at a determined frequency using a mechanical impedance instrument and measuring a response frequency. The response frequency is compared to an acceptable frequency range to determine whether the insert is properly installed.Type: GrantFiled: June 13, 2008Date of Patent: November 15, 2011Assignee: The Boeing CompanyInventors: Michael P. Kuntz, Mark L. Younie, Gary E. Georgeson

Patent number: 7970558Abstract: A method for monitoring a signal from a cycle switch mounted to a lubrication divider block system. The method comprises receiving a signal from a remotely located cycle switch that is mounted to a divider block, wherein the cycle switch is responsive to the motion of a piston in the divider block. The number of cycles of the cycle switch are counted based on the signal from the cycle switch. The number of cycles is stored in a computer readable medium and the amount of lubricant used is calculated based on the number of cycles. The amount of lubricant used is then stored in the computer readable storage medium.Type: GrantFiled: April 13, 2010Date of Patent: June 28, 2011Assignee: Coltec Industrial Products LLCInventor: Curtis Roys
