Publication number: 20150282262Abstract: A non-isolated light-emitting diode (LED) driving circuit has a rectifier, a switching device, a sampling resistor, a power supply unit, a controller unit and a lighting unit. The controller unit samples a voltage at the sampling resistor to compare the sampling voltage with reference voltage to determine if the switching device is turned on or off When the switching device is turned on, a charging current outputted from the rectifier charges the power supply unit and the power supply unit simultaneously discharges to supply power to the lighting unit. When the switching device is turned off, a discharging current outputted from the power supply unit supplies power to the lighting unit. As there are no transformer and electrolytic capacitor, the non-isolated LED driving circuit is simplified, durable and cost-effective.Type: ApplicationFiled: March 25, 2014Publication date: October 1, 2015Applicant: Xi'An Quanxin Electronics Co.Inventors: Xinquan Lai, Jie Han, Huisen He, Lili Shao

Patent number: 7844449Abstract: A scalable two-pass scalable probabilistic latent semantic analysis (PLSA) methodology is disclosed that may perform more efficiently, and in some cases more accurately, than traditional PLSA, especially where large and/or sparse data sets are provided for analysis. The improved methodology can greatly reduce the storage and/or computational costs of training a PLSA model. In the first pass of the two-pass methodology, objects are clustered into groups, and PLSA is performed on the groups instead of the original individual objects. In the second pass, the conditional probability of a latent class, given an object, is obtained. This may be done by extending the training results of the first pass. During the second pass, the most likely latent classes for each object are identified.Type: GrantFiled: March 30, 2006Date of Patent: November 30, 2010Assignee: Microsoft CorporationInventors: Chenxi Lin, Jie Han, Guirong Xue, Hua-Jun Zeng, Benyu Zhang, Zheng Chen, Jian Wang
