Patent number: 9865440Abstract: A sputtering apparatus includes a sputtering cathode and a target overlying the sputtering cathode. A shield overlies the target and forms an aperture configured to direct sputtering particles onto a substrate. The shield includes a lower shield portion overlying the target, a channel outlet overlying the lower shield portion, and an upper shield portion overlying the channel. In some embodiments the shield includes a first shield and a second shield. The first shield includes a front gas injection outlet. The second shield overlies the first shield and forms the aperture. In various embodiments, the second shield is operable to adjust plasma confinement between the first shield and the second shield.Type: GrantFiled: November 29, 2010Date of Patent: January 9, 2018Assignee: Seagate Technology LLCInventors: Stan Kassela, Wei Xu, Lim Boon Leong, Liu Hao Jun, Chun Wai Tong, Weilu H.

Patent number: 9632917Abstract: Software testing uses a plurality of test cases, where each of the test cases includes a plurality of test tasks. The test cases are analyzed to obtain at least one reusable test task sequence between at least two test cases. The reusable test task sequence includes at least one identical test task. The test cases are divided into at least one test case group according to the reusable test task sequence, where the test cases in each of the test case groups has at least one reusable test task sequence. For each of the test cases of the at least one test case group, an execution script of each test case is generated by using an execution script of a reusable test task, where the execution script of each test case includes at least one of backup or restore for the reusable test task sequence.Type: GrantFiled: January 19, 2015Date of Patent: April 25, 2017Assignee: International Business Machines CorporationInventors: Duan Cai, Liu Hao, Qiang Li, Lan Qian Peng, Yan Yan, Chuan Jie Zheng

Publication number: 20150153629Abstract: The present invention is directed to a camera lens filter assembly including a camera lens filter and an included optical component. The optical component is installed on an optic mounting part; and a clamp is mounted on a clamp mounting part, so the clamp can press to tighten against the optical component for the purpose of assembly. The present invention efficiently prevents air, dust and other environmental pollutants from reaching the front surface of the camera lens and will also seal to secure the camera lens filter to the camera lens barrel in a way that it will not dismount itself due to vibration, use or other operating conditions.Type: ApplicationFiled: November 26, 2014Publication date: June 4, 2015Inventors: Liu Hao, Lu Yi, Robert Michael Rose

Patent number: 7471827Abstract: Systems and methods for automatic generation of a browsing path across image content to present areas with high attention value are described. In particular, an image is modeled via multiple visual attentions to create a respective set of attention objects for each modeled attention. The attention objects and their respective attributes are analyzed to generate a browsing path to select ones of the attention objects. The browsing path is generated to optimize the rate of information gain from the attention objects as a function of information unit cost in terms of time constraints associated with multiple image browsing modes.Type: GrantFiled: October 16, 2003Date of Patent: December 30, 2008Assignee: Microsoft CorporationInventors: Xing Xie, Wei-Ying Ma, Hong-Jiang Zhang, Liu Hao
