20160109013 | DRIVELINE COMPONENT HAVING RING GEAR INTEGRALLY FORMED WITH TUBULAR DRIVE MEMBER - The present teachings provide for a power transfer device and method of forming a power transfer device that includes a unitarily formed transfer member and a support member. The transfer member can be supported within a housing for rotation about an input member and can be coupled to the input member to receive rotational power therefrom. A ring gear defined by the transfer member can meshingly engage with a pinion gear. The support member can be disposed concentrically about the input member and be rotatable about a first axis relative to the housing. The support member can have a first end and a second end. The first end of the support member can be supported for rotation relative to the housing by a support bearing. The second end of the support member can be received within a bore defined by the transfer member and fixedly coupled thereto for common rotation. | 04-21-2016 |

20150161030 | DETECTING METHOD AND SYSTEM FOR CONCURRENCY BUGS - In a detecting method for concurrency bugs, a Current Fetter Set is defined for a dynamic instance of a static instruction in program invariants. A Belonging Invariants Set and an Enforcing Invariants Set from the Current Fetter Set are extracted. The Belonging Invariants Set and the Enforcing Invariants Set are pruned to obtain final results after pruning and storing the final results after pruning in an invariants database. Invariant violation is detected using a detection unit whether a first Current Fetter Set dissatisfying with corresponding Belonging Invariants Set and Enforcing Invariants Set is shown. If yes, the first Current Fetter Set is determined to contain a bug, the detection unit generating a violation report. A currently-running thread (the violated thread) is stalled to prevent running of the bug. | 06-11-2015 |
20150163668 | PROTECTING SYSTEM AND METHOD FOR PRIVACY INFORMATION IN MOBILE TERMINAL - The present disclosure disclosures a protecting system and method for privacy information in a mobile terminal. In the system, a crowdsourcing database stores security strategy information of applications. An interaction management module receives a recommendation request of security strategy sent by the mobile terminal. A recommendation algorithm module calculates according to the recommendation request of security strategy to obtain corresponding recommended security strategy. An interaction management module recommends the recommended security strategy to the privacy protecting module. A privacy protecting module notifies a user and assists the mobile terminal to set privacy protection strategy according to the recommended security strategy recommended by the interaction management module, and protects the privacy information in the mobile terminal according to the privacy protection strategy. The system can set privacy protection dynamically. In this way, user experience is improved. | 06-11-2015 |
