  • Publication number: 20220016409
    Abstract: A sterilizable connector may include a sterilization fluid reservoir to provide a sterilization fluid. The sterilizable connector may include a connector. The connector may include a first end to receive a first tube to connect to a medical device (e.g., directly or via one or more intervening components). The connector may include a second end to receive a second tube to connect to a patient (e.g., directly or via one or more intervening components). The connector may include a body to couple the first end to the second end to enable fluid transfer between the first tube and the second tube. The connector may include a body opening to couple to the sterilization fluid reservoir. The sterilizable connector may include a sterilization fluid injector to inject the sterilization fluid from the sterilization fluid reservoir to the connector.

  • Patent number: 5824897
    Abstract: The invention discloses a helicopter rotor blade static balancing fixture. First, the blade is rooted to provide a basis for accurate station or spanwise measurements. Then, weight information is measured by the load cells, and the distance from the weight measurement to the leading edge of the blade is measured by linear transducers, respectively, and communicated to a computer. The computer calculates the spanwise moment, compares the calculated value to the factory standard spanwise moment, and calculates and displays a recommended weight adjustment. The computer calculates the chordwise moment, compares the calculated value to the factory standard chordwise moment, and calculates and displays a recommended weight adjustment.
