Patent number: 9935414Abstract: A commutator has a conductive layer, a segment layer and an insulating layer separating the conductive layer and the segment layer. The segment layer includes multiple commutator segments. A mounting hole is defined along an axis of the commutator passing through the conductive layer. The three-layer structure of the commutator forms a capacitor having an increased confronting area and reduced inter-plate distance. The capacitor thus has a greater capacitance and hence greater EMI absorbing capability, making it possible to reduce EMI emissions without additional EMI reduction components outside the commutator. A rotor and a motor employing the commutator are also disclosed.Type: GrantFiled: December 11, 2015Date of Patent: April 3, 2018Assignee: JOHNSON ELECTRIC S.A.Inventors: Qing Bin Luo, Chi Wai Lai, Wen Ming Wu, Zhao Sen Meng, Xiao Lin Ren, Xian Xue Ao, Bei Bei He, Hong Jiang Zhao, Ying Song Ye

Patent number: 8946978Abstract: A lighting device (2) comprises a light source (210) having a main forward emission direction (20), and an envelope (220) in which the light source (210) is arranged. The envelope (220) comprises an upper portion (225) having scattering properties and being arranged to reflect a part of the light from the light source (210) laterally and backwardly relative to the main forward emission direction (20) and transmit a part of the light from the light source (210). The light intensity distribution of the lighting device (2) is more uniform, as backward and lateral light intensity is increased while the light in the main forward emission direction (20) is still admitted.Type: GrantFiled: October 19, 2012Date of Patent: February 3, 2015Assignee: Koninklijke Philips N.V.Inventors: Johannes Petrus Maria Ansems, Joris Hubertus Antonius Hagelaar, Peter Johannes Martinus Bukkems, Vincent Stefan David Gielen, Reinier Imre Anton Den Boer, Shi Bei He

Patent number: 8194953Abstract: The present invention provides a method and system of material identification using binocular steroscopic and multi-energy transmission image. With the method, any obstacle that dominates the ray absorption can be peeled off from the objects that overlap in the direction of a ray beam. The object that is unobvious due to a relatively small amount of ray absorption will thus stand out, and the material property of the object, such as organic, mixture, metal and the like can be identified. This method lays a fundament for automatic identification of harmful objects, such as explosive, drugs, etc., concealed in a freight container.Type: GrantFiled: July 28, 2008Date of Patent: June 5, 2012Assignees: Nuctech Company Limited, Tsinghua UniversiyInventors: Yali Xie, Qitian Miao, Hua Peng, Kejun Kang, Haifeng Hu, Zhiqiang Chen, Xueguang Cao, Chuanxiang Tang, Jianping Gu, Xuewu Wang, Hongsheng Wen, Bei He, Yaohong Liu, Shangmin Sun, Quanwei Song, Jin Lin, Xianli Ding
