Publication number: 20120294177Abstract: The present disclosure discloses a method for multi-homing path selection of a stream control transmission protocol (SCTP). The method includes the following steps of: starting quality evaluation of paths; calculating a quality evaluation value of each path; comparing the quality evaluation value of each path; and selecting a path with the highest quality evaluation value to transmit a data message. The present disclosure also discloses an apparatus for multi-homing path selection of an SCTP. By adopting the method and the apparatus, a network selects the path with the highest quality evaluation value to transmit a data message. As long as path faults affect the transmission efficiency, other path with better quality is selected for transmission, thus the capability of the network of dealing with all kinds of path faults can be improved, and the data transmission speed and quality are further improved.Type: ApplicationFiled: October 15, 2010Publication date: November 22, 2012Applicant: ZTE CORPORATIONInventors: Xincheng Yan, Xiaowei Ji, Changjiang Yang, Jingyuan Chen, Ying Tan, Jun Du, Aimin Wang, Jianye Liu

Publication number: 20120222754Abstract: A structure of water-saving device includes a base, an adjusting ring and a gland. The adjusting ring is mounted in a water-inlet channel. The gland is movably positioned in the base to limit the adjusting ring. A central part of a top surface of the gland sinks downward to form a recess. When water flow impacts the gland, the gland pushes the adjusting ring, such that the adjusting ring is deformed. Since a difference of pressure occurs between a top and bottom surfaces of the gland, the larger the water pressure is, the larger the force from the gland toward the adjusting ring becomes; thus the degree of deformation of the adjusting ring also becomes large, such that the area between the adjusting ring and the bottom surface of the base for water flowing through decreases and the flow of water gradually achieves a stable value.Type: ApplicationFiled: October 24, 2011Publication date: September 6, 2012Inventors: Jian-ke Huang, Sheng-chao Dai, Sheng-jun Du

Publication number: 20100262423Abstract: Described is a technology by which a feature compensation approach to speech recognition uses a high-order vector Taylor series (HOVTS) approximation of a model of distortions to improve recognition accuracy. Speech recognizer models trained with clean speech degrade when later dealing with speech that is corrupted by additive noises and convolutional distortions. The approach attempts to remove any such noise/distortions from the input speech. To use the HOVTS approximation, a Gaussian mixture model is trained and used to convert cepstral domain feature vectors to log spectrum components. HOVTS computes statistics for the components, which are transformed back to the cepstral domain. A noise/distortion estimate is obtained, and used to provide a clean speech estimate to the recognizer.Type: ApplicationFiled: April 13, 2009Publication date: October 14, 2010Applicant: Microsoft CorporationInventors: Qiang Huo, Jun Du
