Patent number: 9927616Abstract: Transparent displays enable many useful applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light.Type: GrantFiled: August 16, 2016Date of Patent: March 27, 2018Assignee: Massachusetts Institute of TechnologyInventors: Chia Wei Hsu, Wenjun Qiu, Bo Zhen, Ofer Shapira, Marin Soljacic

Patent number: 9898257Abstract: An automatic probe construction system and the method thereof are provided. The automatic probe construction system includes a data dereference analysis module, a probe selection module, and a probe verification module. The data dereference analysis module dereferences a plurality of target data of an electronic apparatus according to a plurality of pointers, and constructs a plurality of candidate probes.

The probe verification module searches the executable image file for an instruction code corresponding to the dedicated probe, to verify the dedicated probe. Therefore, the dedicated probe can be constructed automatically, and the number of the dedicated probes is thus limited.Type: GrantFiled: February 4, 2016Date of Patent: February 20, 2018Assignee: NATIONAL CHIAO TUNG UNIVERSITYInventors: Shiuhpyng Shieh, Chi-Wei Wang, Chia-Wei Wang, Chia-Wei Hsu

Publication number: 20170299149Abstract: A transparent display includes nanoparticles having wavelength-selective scattering (e.g., resonant scattering) to preferentially scatter light at one or more discrete wavelengths so as to create images. The nanoparticles transmit light at other wavelengths to maintain a high transparency of the display. The nanoparticles are disposed in proximity to a thin film, which can enhance the scattering the process by reflecting light back to the nanoparticles for re-scattering or increasing the quality factor of the resonant scattering.Type: ApplicationFiled: March 31, 2017Publication date: October 19, 2017Inventors: Marin SOLJACIC, Bo Zhen, Emma Anquillare, Yi Yang, Chia-Wei Hsu, John D.

Patent number: 9716016Abstract: One or more techniques or systems for forming an electrostatic discharge (ESD) clamp are provided herein. In some embodiments, the ESD clamp includes a first pad and a second pad. For example, the first pad is a positive supply voltage (Vdd) pad and the second pad is a negative supply voltage (Vss) pad.

Additionally, metal regions are configured to be in contact with at least some of at least one of the active regions or the oxide regions and the first pad. In some embodiments, the metal regions are substantially wedge shaped. In this manner, an ESD clamp with enhanced performance is provided, at least because the respective active regions are substantially rounded or associated with obtuse angles, for example.Type: GrantFiled: December 20, 2012Date of Patent: July 25, 2017Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventor: Chia-Wei Hsu

Patent number: 9458989Abstract: Disclosed herein are transparent color displays with nanoparticles made with nonlinear materials and/or designed to exhibit optical resonances. These nanoparticles are embedded in or hosted on a transparent substrate, such as a flexible piece of clear plastic or acrylic. Illuminating the nanoparticles with invisible light (e.g., infrared or ultraviolet light) causes them to emit visible light. For example, a rare-earth doped nanoparticle may emit visible light when illuminated simultaneoulsy with a first infrared beam at a first wavelength ?1 and a second infrared beam at a second wavelength ?2. And a frequency-doubling nanoparticle may emit visible light when illuminated with a single infrared beam at the nanoparticle's resonant frequency. Selectively addressing these nanoparticles with appropiately selected pump beams yields visible light emitted from the nanoparticles hosted by the transparent substrate in a desired pattern.Type: GrantFiled: December 30, 2013Date of Patent: October 4, 2016Assignee: Massachusetts Institute of TechnologyInventors: Chia Wei Hsu, Wenjun Qiu, Bo Zhen, Ofer Shapira, Marin Soljacic
