Abstract: A valve train carrier comprises an enclosed main passage configured to be in pressure communication with pressurized engine oil and an enclosed secondary passage adjacent the main passage. An oil barrier between the main passage and secondary passage is configured to permit oil flow from the main passage to the secondary passage such that the secondary passage receives oil from the main passage at a lower pressure than oil in the main passage. Outlet passages permit discharge of oil from the carrier.

Abstract: According to an exemplary embodiment a random number generator system, comprises a pre-processing unit, and a random number generation unit, wherein the pre-processing unit is adapted to calculate an internal seed out of an external seed and/or system variables and/or dynamic variables related to stack, and wherein the random number generation unit is adapted to generate a random number by using a determined function, wherein the determined function is a function of the internal seed and of at least one dynamic runtime variable related to the stack.
