Patent number: 8772197Abstract: One aspect of the present invention relates to reactive compositions and methods of use thereof, wherein a metal oxide cluster is used to connect a reactive group (or groups) to the surface of a substrate. In certain embodiments, the reactive group in the compositions decomposes organophosphate agents through nucleophilic hydrolysis. In certain embodiments, the reactive group in the compositions is bactericidal. Remarkably, the use of metal oxide clusters in the disclosed compositions and methods permits incorporation of higher quantities of nucleophilic and bactericidal groups without the difficulties associated with having to pretreat the substrate prior to its association with the reactive groups.Type: GrantFiled: August 18, 2008Date of Patent: July 8, 2014Assignee: Massachusetts Institute of TechnologyInventors: Trevor Alan Hatton, Lev E. Bromberg, Huan Zhang

Patent number: 8706158Abstract: The present invention provides a mobile phone for authenticating Subscriber Identification Module (SIM) card and a SIM card authentication method adapted for the mobile phone. Once a SIM card is inserted into the mobile phone, the mobile phone acquires a phone number associated with the inserted SIM card and identifies whether the acquired phone number has been stored in the non-erasable programmable memory of the mobile phone. If yes, the user is legal and can use the mobile phone, if no, then the user is illegal and cannot use the mobile phone. Therefore, the mobile phone protects and hides stored information from the user.Type: GrantFiled: December 30, 2011Date of Patent: April 22, 2014Assignees: Fu Tai Hua Industry (Shenzhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Zhang-Yong Zheng, Bi-Qing Luo, Huan-Huan Zhang, Xin Lu

Publication number: 20120066532Abstract: An electronic device includes a dynamic memory, a static memory, a detection unit, a copy unit and a set unit. The dynamic memory stores an interrupt monitoring program. The interrupt monitoring program monitors whether an interrupt request is generated, and generates an interrupt signal when the interrupt request is generated. The detection unit detects whether the electronic device needs to enter a sleep mode, and generates a detection signal if the electronic device needs to enter the sleep mode. The copy unit copies the interrupt monitoring program from the dynamic memory to the static memory in response to the detection signal, and runs the interrupt monitoring program in the static memory for monitoring whether an interrupt signal is generated. The set unit sets the dynamic memory into a self-refresh mode in response to the detection signal.Type: ApplicationFiled: March 16, 2011Publication date: March 15, 2012Applicants: HON HAI PRECISION INDUSTRY CO., LTD., FU TAI HUA INDUSTRY (SHENZHEN) CO., LTD.Inventors: SHIH-FANG WONG, XIN LU, XUE-SHUN LIU, JUN-JIE LI, BIAO-GENG ZHONG, HUAN-HUAN ZHANG, DAN WANG, BI-QING LUO, FEI WANG, LI-XIA PENG
