Patent number: 11479126Abstract: A system for compensating acceleration of electrical motorbike includes a throttle unit and an electro-mechanic assembly. After the electrical motorbike starts, the throttle unit receives external operation from a rider for generating a series of original throttle signal. An acceleration compensating module calculates a throttle variation rate based on the original throttle signal and variation of a throttle operation magnitude, and calculates a throttle compensating value based on the throttle variation rate when the throttle variation rate is larger than or equal to a correction threshold. A throttle compensating module receives and sums the original throttle signal and the throttle compensating value up for generating a new throttle signal. A torque controller generates a corresponding torque command based on the new throttle signal, and outputs the torque command to the electro-mechanic assembly for operation.Type: GrantFiled: July 26, 2019Date of Patent: October 25, 2022Assignees: DELTA ELECTRONICS, INC., KWANG YANG MOTOR CO., LTD.Inventors: Chien-Ping Huang, Chung-An Hsieh, Hsiang-Hsi Huang, Cheng-Hsien Huang

Patent number: 11482993Abstract: Embodiments herein describe placing a filter network at one of the inputs of the comparator to avoid injecting unequal amounts of kickback noise into the inputs of the comparator. In one embodiment, the filter network matches the impedance seen at the inputs of the comparator. As a result, the amount of kickback noise is essentially equal at the inputs even though the input signals may be at different frequencies. Thus, the kickback noise is essentially cancelled out so that this noise has little to no impact on the output of the comparator.Type: GrantFiled: February 23, 2021Date of Patent: October 25, 2022Assignee: XILINX, INC.Inventors: Kai-An Hsieh, Tan Kee Hian
