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: 11310392Abstract: The present disclosure provides a fluid-optical encryption system and a method thereof. The fluid-optical encryption system uses a fluid surface that changes topology over time to modulate the wave front of an electromagnetic signal in an encryption, decryption, authentication or other communication system. The electromagnetic signal can be pulsed or continuous, coherent or non-coherent, and can be optical or in another wavelength range such as micrometer or infrared. The information carrying signal is either transmitted through the fluid system or reflected off the surface of the fluid system. The fluid system time dependent change can be induced by mechanical vibration in the fluid container, distorting the fluid container, acoustic waves through the fluid, or by surface tension changes at the boundary of the fluid cause by electrowetting or electrostatic effects. The fluid surface can exhibit patterns that oscillate or change periodically, or change in a chaotic manner.Type: GrantFiled: December 12, 2017Date of Patent: April 19, 2022Assignee: National Tsinghua UniversityInventors: Wei-Chih Wang, David R.
