Patent number: 10612861Abstract: A thermosiphon system includes a condenser, an evaporator, and a condensate line fluidically coupling the condenser to the evaporator. The condensate line can be a tube with parallel passages can be used to carry the liquid condensate from the condenser to the evaporator and to carry the vapor from the evaporator to the condenser. The evaporator can be integrated into the tube. The condenser can be constructed with an angled core. The entire assembly can be constructed using a single material, e.g., aluminum, and can be brazed together in a single brazing operation.Type: GrantFiled: January 11, 2018Date of Patent: April 7, 2020Assignee: Google LLCInventors: Jeremy Rice, Jeffrey S. Spaulding, Huan D. Nguyen

Patent number: 8086310Abstract: A method and an apparatus for projecting an end of service (EOS) and/or an elective replacement indication (ERI) of a component in an implantable device and for determining an impedance experienced by a lead associated with the implantable device. An active charge depletion of an implantable device is determined. An inactive charge depletion of the implantable device is determined. A time period until an end of service (EOS) and/or elective replacement indication (ERI) of a power supply associated with the IMD based upon the active charge depletion, the inactive charge depletion, and the initial and final (EOS) battery charges, is determined. Furthermore, to determine the impedance described above, a substantially constant current signal is provided through a first terminal and a second terminal of the lead. A voltage across the first and second terminals is measured. An impedance across the first and second terminals is determined based upon the constant current signal and the measured voltage.Type: GrantFiled: May 21, 2010Date of Patent: December 27, 2011Assignee: Cyberonics, Inc.Inventors: Randolph K. Armstrong, Albert W. Guzman, Huan D. Nguyen
