Publication number: 20210133371Abstract: Aiming at insufficient drying seafood on-board caused by hull swings, the present invention involves the establishment of location correction system for processing seafood transportation displaced by wind waves and anti-accumulation drying processing method. This invention employs CFD-DEM method to simulate the state and distribution of the material particles modulated by the deflector angle and wind speed. Finally, the optimized rotation angle of deflector and wind speed are obtained where material particles are equally distributed. Meanwhile, the uniform and fast drying of the marine products in the swinging hull are achieved. This invention shows the great advantages of high efficiency, automation and continuity.Type: ApplicationFiled: September 10, 2020Publication date: May 6, 2021Inventors: Yuting DING, Xuxia ZHOU, Shichen ZHU, Zhigang KE, Long LIN, Yucong ZHANG, FangRui YU, Zhaoyong LIN, Ning LIN, Xia XU

Publication number: 20210065941Abstract: This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.Type: ApplicationFiled: February 20, 2019Publication date: March 4, 2021Inventors: Robin Ihnfeldt, Eunjeong Kim, Sungho Jin, Renkun Chen, Xia Xu

Patent number: 8796012Abstract: A technique for high sensitivity evanescent field molecular sensing employs a detection scheme that simultaneously couples a polarized beam to a single mode of a waveguide, and couples the polarized beam out of the waveguide to specularly reflect the beam by the same grating. Strong interaction with the single (preferably TM) mode is provided by using a silicon on insulator (SOI) wafer having a waveguide thickness chosen between 10-400 nm so that the majority of the mode field strength spans the evanescent field. Well known, robust techniques for producing a grating on the waveguide are provided. Interrogation from a backside of the SOI wafer is taught.Type: GrantFiled: December 2, 2009Date of Patent: August 5, 2014Assignee: National Research Council of CanadaInventors: Bill Sinclair, Jens Schmid, Philip Waldron, Dan-Xia Xu, Adam Densmore, Trevor Mischki, Greg Lopinski, Jean Lapointe, Daniel Poitras, Siegfried Janz
