Abstract: A system and computer software product for providing flexible control of access to information system data, files and other resources is presented. The invention employs a three cornered data arrangement that provides both fine grained access control and the simplicity of coarser grained access control systems. In addition the invention benefits from optional hierarchical inheritance along an unlimited number of hierarchies. Users can be assigned access to a resource in multiple ways. Access can be granted on a resource by resource basis or alternately to a group of resources. Access can also be inherited through three different channels. In addition these permission assignments can specify the extent of the control that the user will have over the resources that they are granted access to. Inheritance of access permissions through these hierarchies is an optional control that can be set within the invention.

Abstract: Invention provides a method and apparatus for remote script execution for secure internet browsing by filtering and partially re-writing a web page for the purpose of enabling the user to get the benefit from the complete code on the page without the risk associated with the potentially dangerous portions of code on that page. The invention executes the complete code set in a rendering computer processor that acts as an intermediary between the user's computer processor and the internet, and passing on, from the rendering computer to the user's computer, only those portions of code that can be safely rendered by the user's browser. This allows the user to see the output of potentially dangerous scripting code without being exposed to the dangers of hosting and executing that scripting code.

Abstract: Apparatus and method for transforming Web resources into safe versions such that malicious code on the resources cannot attack the client viewing the resources. The invention separates the processing of insecure code from the processing of benign code. For Web pages, the benign code is displayed immediately to the client while insecure code is processed on a separate machine. Once insecure code is processed, benign outputs of that code are passed to the client for display. The invention safeguards the client against known and zero day exploits without requiring a catalog of malware/virus signatures, heavyweight code checkers, complete page re-writing or highly restrictive access policies. The invention provides the client with complete malware blocking while retaining most of the original functionality of the Web resource.

Abstract: Apparatus and method for transforming internet resources into safely rendered versions of the same. The invention provides transformative rendering of internet resources to remove malicious code before displaying in a browser or its associated application. Malicious code blockage is accomplished by re-writing all code that is to be transferred to the client browser. Since malicious code is often disguised (or obfuscated), the invention will not attempt to rewrite the entire code set on the page but will still make available the functionality of that code through frequent interaction between the invention's rendering processor and the client browser.

Abstract: Apparatus and method to detect corrosion in metal junctions. Corroded metal junctions are usually discovered by visual inspection. The present invention detects corrosion in metal junctions when it is not visually apparent. A corroded metal junction acts as a nonlinear device. It generates harmonics and other nonlinear products (such as intermodulation) of any signals applied to the junction. The presence of relatively high level harmonics and/or intermodulation products indicates directly that corrosion has occurred. To detect corrosion in a metal junction, one couples a fundamental frequency signal (f0) into the junction and tests for harmonics of that frequency, especially the third harmonic. Harmonic frequency signals that are relatively large (i.e., above the harmonics generated by the testing system) indicate the presence of corrosion. Measurements to determine if a metal junction is corroded are performed without disturbing the junction.

Abstract: Apparatus and method to identify chafing of a conduit, thereby reducing the failure of any system which would be damaged or whose function would be impaired by abrasion of the conduit. Such a system may carry electrical power, fuel, other fluid, hydraulics, pneumatics, optical, or electromagnetic signals. Wear caused by rubbing against external structures is detected by wrapping the conduit with a sensing element, which may be a conductive wire, waveguide, fiber optic cable, or a tube (wound around the conduit or enclosing it) that holds a fluid under pressure. The sensing element is positioned so that chafing on the conduit electrically contacts, breaks, or punctures the sensing element well before the conduit fails.
