20080197327 | Wide band gap semiconductor templates - The present invention relates to a thin film structure based on an epitaxial (111)-oriented rare earth-Group IVB oxide on the cubic (001) MgO terminated surface and the ion-beam-assisted deposition (“IBAD”) techniques that are amendable to be over coated by semiconductors with hexagonal crystal structures. The IBAD magnesium oxide (“MgO”) technology, in conjunction with certain template materials, is used to fabricate the desired thin film array. Similarly, IBAD MgO with appropriate template layers can be used for semiconductors with cubic type crystal structures. | 08-21-2008 |

20090133004 | GENERIC FRAMEWORK FOR RUNTIME INTERCEPTION AND EXECUTION CONTROL OF INTERPRETED LANGUAGES - A system and method for controlling execution of an interpreted language. Statements of the interpreted language to be executed by a script engine are intercepted by a protection module and control is passed to a script helper module that is associated with the script engine. The script helper module establishes a secure communications channel with an authorization component and passes the statements and an authorization request to the authorization component. The authorization component sends a reply to the script helper module which either permits the script engine to execute the statement or cancels the attempted execution. When the script engine is loaded, a list is updated identifying the script engine. If a script helper module is not present for the loaded script engine, a boot-strap loader is called to load the script helper module. A special information block contains data as to the location of the interception points. | 05-21-2009 |
20120047556 | ON-LINE CENTRALIZATION AND LOCAL AUTHORIZATION OF EXECUTABLE FILES - A system and system for controlling the execution of executable files. The executables are identified by either a cryptographic digest or a digital certificate. The cryptographic digest is computed from the binary image of the executable. An executable that is attempting to execute is intercepted by a protection module that consults a database of stored rules over a secure channel to determine whether or not the executable can be identified as a permitted executable and whether or not it has permission to execute on a particular computer system under certain specified conditions. If a stored permission is available, it is used to control the execution. Otherwise, the user is consulted for permission. | 02-23-2012 |

20120181162 | Method for Stabilizing Carbon-Containing Fibre and Method for Producing Carbon Fibre - The group of inventions pertains to the field of producing high-strength carbon fibres, which can be primarily manufactured from an organic starting material (precursor). A method for stabilizing a carbon-containing fibre (precursor) is claimed, in which the fibre is placed into a gaseous medium and subjected to treatment with microwave radiation as the gaseous medium is heated. More specifically, the fibre is placed into a working chamber filled with a gaseous medium, the latter is heated by heating the chamber (for example, the walls thereof) while the fibre is treated with microwave radiation. According to a second aspect of the invention, a method for producing a carbon fibre is claimed, comprising, as a minimum, fibre stabilizing and carbonizing stages, in which the precursor is stabilized by means of the above-described method by subjecting the fibre to microwave radiation as the medium in which the fibre is immersed is heated. After the fibre has been carbonized, it is possible, as an alternative, for said fibre to be additionally coated with graphite. If necessary, the stabilized fibre can also be carbonized and/or coated with graphite by the complex treatment thereof with microwave radiation as the medium in which the fibre has been placed for carbonizing/coating with graphite is heated. As a result, the time taken to stabilize the precursor fibres is reduced, thereby affording a reduction in the energy consumption and an increase in the productivity of the process for producing carbon fibre. | 07-19-2012 |
