Patent number: 12105894Abstract: A key triggering method is provided. The key triggering method is sensitive to trigger and suitable for fast repeated pressing. The key triggering method includes: presetting a trigger threshold; detecting, by a combination of a main controller and a sensor, a displacement stroke and displacement direction of a key; determining whether a movement distance of the key in a current displacement direction is greater than the trigger threshold; and switching the key between an on state and an off state according to a determination result. The key triggering method can sensitively identify a user's action for fast repeated pressing.Type: GrantFiled: March 14, 2023Date of Patent: October 1, 2024Assignee: G.Tech Technology LtdInventor: Baisong Li

Publication number: 20240001438Abstract: Disclosed is an amorphous nanocrystalline alloy strip. When the amorphous nanocrystalline alloy strip is cut into a plurality of narrow strips having a same width of less than or equal to 10 mm, a relative length difference among the plurality of narrow strips is not greater than 0.50%. Further disclosed is a method for manufacturing the amorphous nanocrystalline alloy strip. The amorphous nanocrystalline alloy strip has good surface flatness. The transverse temperature non-uniformity of molten steel inside a melting pool and the surface temperature non-uniformity of a cooling roller within a strip manufacturing position range are controlled in a process of manufacturing the amorphous nanocrystalline alloy strip, so that the surface flatness of the manufactured strip is improved. The manufacturing process is simple and convenient.Type: ApplicationFiled: March 16, 2021Publication date: January 4, 2024Inventors: Wenzhi CHEN, Guodong LIU, Baisong LI, Yang SHI, Zhigang LI

Patent number: 7649151Abstract: A gear-type key switch of a keyboard device of the present invention includes a key top, a holder member, four gears, a spring member, a film circuit board and a supporting plate. The spring member and the holder member are located above the supporting plate and below the key top. The film circuit board is located between the supporting plate and the spring member. The holder member forms four pairs of shafts and the four gears are respectively rotatably assembled to the four pairs of shafts. The key top forms at least four rack supporting members on a bottom thereof. The rack supporting members are respectively parallel to the four gears and engage with the four gears to provide the upward and downward movement of the key top. The gear-type key switch of a keyboard device is simple in structure, with low friction force and decreased height.Type: GrantFiled: January 28, 2005Date of Patent: January 19, 2010Inventor: Baisong Li
