    摘要: The present disclosure relates to set of a ohmic contact electrodes on both P-type and N-type layers of a GaN-based light emitting diode (LED) and a fabricating method thereof. The materials of ohmic contact electrodes on both P-type and N-type layers of a GaN-based LED are a metal combination of Cr/Pd/Au. In one embodiment, the fabricating method comprises etching out an N-type GaN layer on an epitaxial structure on a sapphire substrate, and evaporating a P-type transparent electrode layer on the P-type GaN layer, then positioning patterns of the ohmic contact electrodes on both P-type and N-type layers, and then evaporating a metal combination of a Cr layer 50 Å to 500 Å thick, a Pd layer 300 Å to 1000 Å thick and an Au layer 3000 Å to 20000 Å thick in turn on the P-type transparent electrode layer and N-type GaN layer respectively, and then annealing electrodes of the chip, on which the Cr, Pd and Au layers are evaporated in nitrogen atmosphere for 5 minutes to 20 minutes at a temperature from 200 degrees to 450 degrees. Excellent ohmic contact characteristics and better thermal stability are obtained as well as higher oxidation resistance, thus improving the reliability of diode.

    摘要: An improved system for backlighting a visual effect of interest is presented. The system includes a lenticular luminescent lens, an electroluminescent (EL) light source and a power source coupled to the EL light source. The lenticular luminescent lens includes a luminescent substance disposed thereon/therein for providing the visual effect of interest when exposed to stimulating light. The EL light source is affixed to a surface of the lenticular luminescent lens. When the power source applies power to the EL light source, the EL light source activates an area of illumination backlighting the visual effect of interest.

    摘要: Data classification is used to classified input items by associating the input items with one or more classes from a set of one or more classes in a data classification system, including identifying relevant features in an input item to form a feature vector for the input item, receiving at the data classification system an indication of a point-of-view, adjusting the feature vector according to the point-of-view indication or modifying a pattern discriminator (e.g., trainer and classifier) to inline-process feature vectors depending on the provided point-of-view (e.g., SVM custom kernels), and classifying the input item into the set of classes according to the point-of-view. The point-of-view data can be introduced either as a pre-process step prior to passing it off to the pattern discrimination algorithm, or can be incorporated directly into the pattern discrimination algorithm if applicable. The pattern discrimination algorithms can detect arbitrary patterns given a similarly prepared dataset during both training and subsequent classification of unclassified documents.
