Latest Patents

One of Liu's latest patents is a virtual window for aircraft fuselage. This projection-based virtual window system includes a hull, a transparent lens, a projection system, and a controller. The hull is mounted to an interior wall of a passenger cabin and is positioned over a hole in the wall. The transparent lens, secured between the hull and the wall, features a touch sensing layer embedded within. The projection system displays images on the hull's projection surface, while the controller receives instructions from the touch sensing layer to provide images to the projection system.

Another notable patent is a two-step diffusion method for preparing high-performance dual-main-phase sintered mischmetal-iron-boron magnets. This method belongs to the technical field of rare earth permanent magnet materials. The two main phase alloys consist of RE-Fe-B and (Nd, MM)-Fe-B, where RE is Nd or Pr and MM is mischmetal. The process begins with using PrHoFe strip-casting alloy as a diffusion source, followed by coating a PrHo-rich layer on the surface of (Nd, MM)-Fe-B hydrogen decrepitation powders. This innovative approach improves coercivity by utilizing higher anisotropic fields of PrFeB and HoFeB.
