Patent number: 11604522Abstract: A dynamic data transmission format adjustment method is provided. Firstly, a peripheral device raw input data is acquired from a device main body of a wireless peripheral device. Then, the peripheral device raw input data is converted into a variable-bit-length peripheral device transmission data according to a dynamic data transmission format conversion rule. Then, a network transmission packet containing the variable-bit-length peripheral device transmission data is generated, and the network transmission packet is transmitted to a wireless receiver of the wireless peripheral device. Then, the variable-bit-length peripheral device transmission data in the network transmission packet is converted and restored into a fixed-bit-length peripheral device transmission data according to the dynamic data transmission format conversion rule. Then, the fixed-bit-length peripheral device transmission data is transmitted from the wireless receiver to a computer host.Type: GrantFiled: April 19, 2022Date of Patent: March 14, 2023Assignee: PRIMAX ELECTRONICS LTD.Inventors: Chun-Nan Su, Chih-Feng Chien, Yun-Jung Lin, Chin-An Lin
