Publication number: 20080098156Abstract: The disclosed systems and methods provide for the protection of protected memory, for example, a hard disk, in a computer system. The systems and methods are configured to re-direct read and write access commands from locations in the protected memory to alternative storage locations. The systems and methods provide the ability for the user to accept or reject any BIOS changes that are to be made to the computing system. In addition, the systems and methods protect against operating system crash due to missing or corrupted files. The systems and methods are additionally operable to recover mistakenly deleted or damaged application data from a hard disk level, as well as to protect the operating system and data of the computing system against virus penetration. In other embodiments, the systems and methods are operable to provide for a security lock to the computing system and its associated data.Type: ApplicationFiled: December 20, 2007Publication date: April 24, 2008Inventors: Andrew Shen, Hanxiang Sun, Zhang Jian

Publication number: 20070277055Abstract: Various embodiments of systems and methods for preserving saved memory states to which a computer system can be restored are disclosed. In certain embodiments, the systems and methods intercept write operations to protected memory locations and redirect them to alternate memory locations. Embodiments of the systems and methods include creation of a table for each memory state. Certain embodiments additionally include a recovery capability, by which the protected memory in the computer system is capable of being restored or recovered to a recovery point that represents a saved memory state. Further embodiments relate to systems and methods for preventing protected memory locations from being overwritten that utilize a plurality of memory state values.Type: ApplicationFiled: August 31, 2006Publication date: November 29, 2007Inventors: Andrew Shen, Hanxiang Sun, Zhang Jian, Janet Vohariwatt, Timothy Murray

Publication number: 20060255287Abstract: A radiation detector has an electron emitter that includes a coated nanostructure on a support. The nanostructure can include a plurality of nanoneedles. A nanoneedle is a shaft tapering from a base portion toward a tip portion. The tip portion has a diameter between about 1 nm to about 50 nm and the base portion has a diameter between about 20 nm to about 300 nm. Each shaft has a length between about 100 nm to about 3,000 nm and an aspect ratio larger than 10. A coating covers at least the tip portions of the shafts. The coating exhibits negative electron affinity and is capable of emitting secondary electrons upon being irradiated by radiation. The nanostructure can also include carbon nanotubes (CNTs) coated with a material selected from the group of aluminum nitride (AlN), gallium nitride (GaN), and zinc oxide (ZnO).Type: ApplicationFiled: May 13, 2005Publication date: November 16, 2006Inventors: Marian Cholewa, Shu Lau, Gyu-Chul Yi, Jin Yoo, Adrian Burden, Lei Huang, Xingyu Gao, Andrew Shen Wee, Herbert Moser
