Abstract: A first operating system and a second operating system are executed by a processor of a computing device. The first operating system has a first user space on which a first user space driver is executed. The second operating system has a second user space on which a second user space driver is executed. A common kernel driver is executed on a common kernel to determine which user space driver made a given function call to the common kernel driver and translate the given function call into a corresponding hardware-specific call, based on said determination. The common kernel driver enables the first user space driver and the second user space driver to access computer hardware of the computing device simultaneously.

Abstract: An insulation system for shafts through which hot gases flow, especially exhaust gas shafts of gas turbines has an insulation layer (20, 40) as well as a flat cover (26, 39), which holds the insulation layer (20, 40) and covers it against the gas flow. The cover (26, 39) is guided by bearing rails (21, 41). In such an insulation system, the number of spacers (22, 23, 24; 47, 48, 49) by which the bearing rails (21, 41) are fastened to a shaft wall (25, 50) shall be minimized. Furthermore, the insulation system shall be able to be manufactured with a high degree of prefabrication in the workshop and with low assembly effort at the construction site. The bearing rails (21, 41) are fastened to the shaft wall (25, 50) with a fixed mount (31, 51) and at least one movable mount (32, 52).
