Publication number: 20190182407Abstract: 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: ApplicationFiled: December 12, 2017Publication date: June 13, 2019Inventors: Wei-Chih Wang, David R.

Patent number: 10288979Abstract: The present disclosure describes the design and fabrication of a Terahertz (THz) beam steering device and a multifunctional patternless flat lens using electro-optic tunable fishnet materials (TFMM) to create a portable THz imaging system. The THz beam steering device and multifunctional patternless flat lens utilize a tunable resonant frequency of TFMM (with a negative refraction index) to achieve a maximum beam steering angle (field of view) and beam modulation. The portable THz scanning system is made by combining the TFMM beam steering device with a pair of continuous wave (CW) photomixer modules powered by two tunable CW lasers with built-in optical isolators, a fiber-optic beam combination and a multifunctional flat lens.Type: GrantFiled: December 12, 2017Date of Patent: May 14, 2019Assignee: National Tsinghua UniversityInventors: Wei-Chih Wang, Chi-Leung Tsui, Da-Jeng Yao

Patent number: 9345424Abstract: A clinical sensing glove system to quantify force, shear, hardness, etc., measured in manual therapies is disclosed. A sensor is disposed in a clinical glove. The sensor undergoes micro-bending, macro-bending, evanescent coupling, a change in resonance, a change in polarization, a change in phase modulation, in response to pressure/force applied. The amount of micro-bending, macro-bending, evanescent coupling, change in resonance, change in polarization, and/or change in phase modulation is proportional to the intensity of the pressure/force. A clinician can quantitatively determine the amount of pressure, force, shear, hardness, rotation, etc., applied.Type: GrantFiled: April 3, 2009Date of Patent: May 24, 2016Assignee: University of WashingtonInventors: Wei-Chih Wang, David J.
