Patent number: 8274278Abstract: An automated, non-destructive anhysteretic magnetization characterization method for studying and modeling soft magnetic materials. This measurement method employs a “reading-waveform” that allows multiple points of reference to be established in tracing out the B waveform. In using the reference values from this waveform, the components of B that cannot be measured directly may be calculated with precision. In turn, the initial magnitude of the B waveform is identified as the unknown component of the anhysteretic state. The processes can be repeated for different values of static fields as well as a function of temperature to produce a family of anhysteretic magnetization curves. The core characterization was performed without physically altering the core, so that the true anhysteretic magnetization curve, and the true B-H loop under applied bias H, is measured.Type: GrantFiled: December 10, 2009Date of Patent: September 25, 2012Assignee: University of South FloridaInventors: Jeremy Walker, Stephen E Saddow

Publication number: 20120155507Abstract: Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.Type: ApplicationFiled: October 18, 2011Publication date: June 21, 2012Applicant: JOHNS HOPKINS UNIVERSITYInventors: Rengaswamy Srinivasan, Michael H.

Patent number: 8197126Abstract: A stirring determining device that determines whether stirring by a stirrer, which stirs liquid contained in a vessel using sound wave generated by a sound-wave generating unit that is attached to the vessel, is successful or unsuccessful. The stirring determining device includes a temperature sensor that measures a temperature of the liquid; and a determining unit that determines whether stirring of the liquid contained in the vessel is successful or unsuccessful depending on the temperature of the liquid measured at least before and after the stirring by the temperature sensor.Type: GrantFiled: January 14, 2010Date of Patent: June 12, 2012Assignee: Beckman Coulter, Inc.Inventor: Nobuyoshi Tsuda
