Patent number: 11883361Abstract: Systems and methods for the transfer of medical fluid are provided. A medical fluid transfer system may comprise a pump configured to transfer fluid through a tube assembly having a first connector configured to couple to a source container and a second connector configured to couple to a target container. The medical fluid transfer system may also comprise a destination sensor configured to output information about the target container. The medical fluid transfer system may further comprise a control system configured to operate the pump based on an operational setting associated with fluid volume; receive measurement data representing a measurement of the target container by the destination sensor, and adjust the operational setting based on an observed volume of fluid transferred to the target container.Type: GrantFiled: January 21, 2022Date of Patent: January 30, 2024Assignee: ICU Medical, Inc.Inventor: Matthias Janssen

Patent number: 11806308Abstract: Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container.Type: GrantFiled: May 10, 2021Date of Patent: November 7, 2023Assignee: ICU Medical, Inc.Inventors: George A. Lopez, Thomas F. Fangrow, Peter Leissling, Matthias Janssen

Publication number: 20190391207Abstract: Thus there is provided a method of determining faults in a stator of a generator, in particular a synchronous generator of a wind turbine. The stator has a plurality of stator coils. A current source for generating a current flow through the winding of the generator is connected. A magnetic field which is generated by stator coils of the generator is detected by a means for detecting a magnetic field. A position of a fault is ascertained by identifying those stator coils which do not generate a magnetic field.Type: ApplicationFiled: January 30, 2018Publication date: December 26, 2019Inventors: Stefan BIEHLE, Matthias JANSSEN

Patent number: 9671370Abstract: A method and system for detecting material loss in a tubular. A method includes identifying a radial cross-sectional area of a tubular as having a loss of material in a wall of the tubular. Responsive to the identifying, an amount of voltage offset present in each of a plurality of measurement signals is determined. Each of the measurement signals provides measurement information for an arc section of the wall. For each of the measurement signals, a zero adjusted signal is produced by adjusting the measurement signal to remove the amount of voltage offset over a length of the tubular for which the identifying recognizes the loss of material. An assessment of wall material loss is produced for each arc section of the wall of the tubular based on the zero adjusted signals. An image of the wall of the tubular showing the wall material loss for each arc section is generated.Type: GrantFiled: October 14, 2015Date of Patent: June 6, 2017Assignee: NATIONAL OILWELL VARCO, L.P.Inventors: Matthias Janssen, Stefan Haberla
