  • Patent number: 10393801
    Abstract: The present invention provides a method and a fault isolation system for detecting errors in an integrated circuit. One feature of the present invention is using a movable second probe to scan and acquire an output signal through the vias or metal line structure of a diagnostic area along a detecting line, so as to find the fault location precisely, and another feature of the present invention is using a cutter in conjunction with the above method to narrow down the fault range. The cutter is used to electrically isolate the portion of diagnostic area step by step for approaching the fault location. This method can help to save a lot of analysis time and also makes the minor fault localization possible.

  • Publication number: 20190182407
    Abstract: 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.

  • Patent number: 10288979
    Abstract: 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.

  • Patent number: 9345424
    Abstract: 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.

  • Publication number: 20160015271
    Abstract: The present invention relates to a palpation diagnostic device, which comprises an optical pressure sensor embedded in a holder; wherein the optical pressure sensor is an optical fiber sensor, or a micro-fabricated waveguide sensor to be disposed on a finger or a palm; and the optical pressure sensor is configured to receive an optical signal whose intensity is attenuated when a force is applied on the optical pressure sensors. Therefore, the palpation diagnostic device of the present invention can provide high sensing sensitivity by attenuating the intensity of the optical signal in the optical pressure sensors which a force is applied on, so it can provide precise and immediate information based on quantitative feedback for the users.
