Abstract: A test equipment is provided, which includes a cabin for providing a low-temperature testing environment for elements under test, and an air curtain structure surrounding the cabin to send dry air toward the cabin. The air curtain structure includes a ring body and a plurality of openings disposedinside the ring body, so that the ring body can send dry air toward the cabin through the plurality of openings, thereby reducing the ambient humidity and preventing condensation water dripping from causing the test equipment damage.

Abstract: Provided herein are high performance electrodes, electrode materials comprising a plurality of active electrode material-containing particles secured within one or more graphenic web, and precursors thereof. Also provided herein are processes of generating the same by an electrospray process.

Abstract: Provided in certain embodiments are high performance graphene fibers and yarns, including components and precursors thereof, and composites comprising the same. Also provided herein are methods of manufacturing such fibers, yarns, composites, and components/precursors thereof.

Abstract: This invention provides a method whereby Si microparticles (“Si MP”) with low cost and nitrogen-abundant chitin fibers from crustacean shells are used as raw materials to produce Si nanoparticles and nitrogen doped carbon composite via a scalable ball milling method. During the ball-milling process, Si MP are downsized, and the chitin fibers are wrapped around the particles. The milled product is then post-thermally treated to obtain Si and nitrogen doped carbon composites.

Abstract: A light emitting device includes a light emitting structure and a distributed Bragg reflector (DBR) structure disposed thereon. The light emitting structure includes an n-type confinement layer, an active layer disposed on the n-type confinement layer, and a p-type confinement layer disposed on the active layer opposite to the n-type confinement layer. The n-type and p-type confinement layers are disposed proximal and distal to the DBR structure, respectively. The DBR structure includes first to Nth DBR units. The first and Nth DBR units are disposed proximal and distal to the light emitting structure, respectively. Each of the first to Nth DBR units has a center reflection wavelength defined by ?+(z?1)?0.

Abstract: A sandwich structure for enhancement of photoluminescence (PL) from luminescent films and the corresponding preparation method are disclosed. The sandwich structure comprises a support, a luminescent film grown on the support, and a single-layer close-packed microsphere array deposited onto the luminescent film. The microspheres have high transmittance excitation light and emitted light, respectively. The low price of dielectric microspheres is beneficial to industrial applications. The stable chemical properties of dielectric microspheres make PL enhanced in a long term. Both metal and non-metal materials can be used as the support in the sandwich structure. These features significantly improve the technique of PL enhancement for luminescent films.

Abstract: A method for retrieving object information is applied to a portable electronic device and includes the following steps. A global position system (GPS) module receives a position signal to get GPS data. A magnetic sensing module senses magnetic field to get azimuth direction data. A touch input module inputs an event which is a movement moving from a touch position towards an object to get input direction data. A processing module gets angle difference data according to the azimuth direction information and the input direction information. The information of the corresponding object from a database according to the parameters of the GPS data is retrieved, and the parameters of the GPS data, the azimuth direction data and the angle difference data are used by the processing module.

Abstract: A Chinese character input device and method thereof are described. The Chinese character input device includes a database, a touch panel and a processing module. The database stores multiple candidate characters, multiple initial consonants and multiple rhymes. Each candidate character is composed of at least one initial consonant and at least one rhyme. The touch panel displays a virtual keyboard including initial consonant virtual keys and rhyme virtual keys and receives a command. The command includes a touch on an initial consonant virtual key to determine an input initial consonant and a release at a rhyme virtual key to determine an input rhyme. The processing module is connected to the database and compares the input initial consonant and input rhyme with the initial consonants and rhymes in the database to generate at least one corresponding candidate character and displays the candidate character on the touch panel for selecting.
