Patent number: 11476789Abstract: A system of driving and controlling a motor is provided. A main controller adjusts frequencies of all or some of pulse waves of an initial pulse width modulation signal to output a pulse width modulation signal according to instruction information. The adjusted frequency of each of the pulse waves is equal to a first preset frequency or a second preset frequency. When a motor driver drives the motor to stably rotate, the motor driver decodes each of the pulse waves having the first preset frequency into a first message and decodes each of the pulse waves having the second preset frequency into a second message. The motor driver arranges and combines all of the first messages and the second messages that are decoded from the pulse waves to obtain the instruction information. The motor driver executes an operation instructed by the instruction information.Type: GrantFiled: October 4, 2021Date of Patent: October 18, 2022Assignee: ANPEC ELECTRONICS CORPORATIONInventors: Yun-Li Liu, Wei-Chih Wang, Yuan-Hung Wang

Patent number: 10637698Abstract: A system and a method for demodulating a frequency shift keying signal are provided. The system includes a power transmitter and a power receiver. The power transmitter generates a frequency shift keying signal including a power signal and a power modulation instruction message. The power receiver detects a non-modulation period of the power signal within a waiting time, and then modulates a frequency of the power signal according to the power modulation instruction message to generate a pulse width modulated signal. The power receiver then calculates a full period of the pulse width modulated signal and then subtracts the non-modulation period from the full period of the pulse width modulated signal to obtain an undemodulated signal.Type: GrantFiled: June 25, 2019Date of Patent: April 28, 2020Assignee: ANPEC ELECTRONICS CORPORATIONInventor: Yuan-Hung Wang
