Abstract: Systems, methods and computer readable media are disclosed for a trusted proxy to intercept communications between an untrusted computerized gaming system and an online multi-player gaming service that requires games to be trusted, allowing the untrusted computerized gaming system to use the multi-player gaming service. In addition to allowing the untrusted computerized gaming system to use the multi-player gaming service in general, the trusted proxy can also limit the extent of the interaction between the untrusted computerized gaming system and the multi-player gaming service.

Abstract: Mechanisms are disclosed that allow for execution of unsigned content and the securing of resources in a closed system when such unsigned content is executing on the system. For example, an application programming interface is used between an access layer implementing unsigned content and an operating system of the closed system. The application programming interface may have sub-interfaces that correspond to sub-layers of the access layer, including a graphics sub-interface, an audio sub-interface, an input sub-interface, and a storage sub-interface. These sub-interfaces present access calls made by the sub-layers to the protected resources of the closed system. By providing the application programming interface, unsigned content, e.g., video games can run on a closed system that is typically designed to run only signed content.

Abstract: Mechanisms allow for execution of unsigned managed code graphic resource call in a closed system when such unsigned content is executing on the system. For example, a managed code graphic resource device is used between an application running unsigned content and a supervisor mode graphic resource device. A managed mode graphics device validates graphic resource calls made by the application. A managed mode graphics device manages resource calls by differentiating between calls that may be made directly to the supervisor mode graphics device, calls that may be pipelined for later action, and calls that may be made to an intermediate device.

Abstract: Systems, methods and computer readable media are disclosed for an overlaying requester to send graphics commands to a game connected to the overlaying requester via a dummy graphics application programming interface (API) object that the game will render over normal game-play graphics. In addition to allowing the overlaying requester to send graphics commands to the game in general, the dummy graphics API object can also limit the extent of the interaction between the overlaying requester and the computerized gaming system.

Abstract: A method of monitoring the fire resistance of hydraulic fluids involves measuring a property of the hydraulic fluid that changes as the hydraulic fluid is used; relating the measurement to the fire resistance of the hydraulic fluid; and if necessary, taking remedial action in order to improve the fire resistance of the hydraulic fluid. A suitable property is the molecular weight of polymer anti-mist additives such as polymethyl methacrylate and the fire resistance may be improved by adding to the hydraulic fluid, a concentrate of the polymer in a suitable solvent when the measured molecular weight falls below an acceptable value.
