  • Patent number: 9230541
    Abstract: This application discloses a method implemented of recognizing a keyword in a speech that includes a sequence of audio frames further including a current frame and a subsequent frame. A candidate keyword is determined for the current frame using a decoding network that includes keywords and filler words of multiple languages, and used to determine a confidence score for the audio frame sequence. A word option is also determined for the subsequent frame based on the decoding network, and when the candidate keyword and the word option are associated with two distinct types of languages, the confidence score of the audio frame sequence is updated at least based on a penalty factor associated with the two distinct types of languages. The audio frame sequence is then determined to include both the candidate keyword and the word option by evaluating the updated confidence score according to a keyword determination criterion.

  • Publication number: 20150090689
    Abstract: Described herein are coating compositions for protecting one-glass solution (OGS) glasses and other display glasses during processing. The coatings are non-reactive to typical indium-tin oxide touch components, metal electrodes, and black matrix inks, and can thus be used to over-coat these materials. In one aspect, the coating compositions described herein can be applied by a screen printing application process in a single layer or in multiple layers and are compatible with CNC edge grinding and acid etching. Further, the protective coatings are rigid, but not brittle, and are durable but still able to be processed rapidly. Additionally, the protective coatings are transparent, allowing alignment marks on the substrates to be visible. Finally, the protective coatings can easily be removed after substrate processing has been completed.

  • Publication number: 20150060401
    Abstract: A method of edge coating a batch of glass articles includes printing masks on surfaces of a glass sheet, where at least one of the masks is a patterned mask defining a network of separation paths. The glass sheet with the printed masks is divided into multiple glass articles along the separation paths. For at least a batch of the glass articles, the edges of the glass articles in the batch are finished to reduce roughness at the edges. Each finished edge is then etched with an etching medium to reduce and/or blunt flaws in the finished edge. A curable coating is simultaneously applied to the etched edges. The curable coatings are pre-cured. Then, the printed masks are removed from the glass articles with the curable coatings. After removing the printed masks, the pre-cured curable coatings are post-cured.
