Patent number: 11618246Abstract: A fiber reinforced metal composite having a metal layer and a fiber layer which are arranged in a stack, and adjacent layers are fixed by bonding; the composite has a two-layered or three-layered structure, wherein one layer is closely adhered to another layer and the thickness of the layer is from 0.6 mm˜0.9 mm. Such structure changes the structure of the existing fiber metal composite characterized by generally having more than three layers, and greatly reduces the thickness of the composite while maintaining good mechanical properties. Also disclosed is an application of fiber reinforced metal composite in the field of luggage case manufacturing, providing two preparation methods for providing fiber reinforced metal case shell with simple and available operations.Type: GrantFiled: November 12, 2020Date of Patent: April 4, 2023Inventors: Wai Chung Wong, Cheuk Nang Sung, Qiu Jin, Song Wang

Publication number: 20200330728Abstract: A catheter for ablation, mapping, injection, and directional control by an external magnetic system has a catheter body, an intermediate section, and a tip section having a tip electrode with an omnidirectional distal end and a concentric needle port. The tip electrode houses a magnetic device and a position sensor in an integrated configuration that facilitates a path in the tip section for extension and retraction of a component, including an injection needle, with reduced stress and friction. The integrated configuration is an efficient use of space in the tip electrode that allows the tip section to carry both the position sensor and the necessary volume of magnetic or magnetizable material to accomplish magnetic navigation. The catheter also includes a very soft and flexible intermediate section and an even softer and more flexible distal transitional section carrying additional magnetic members to facilitate remote magnetic navigation.Type: ApplicationFiled: June 29, 2020Publication date: October 22, 2020Inventors: Christopher J. Birchard, Jerett A. Creed, Wai Chung Wong
