Abstract: A system for routing data in an automatic identification system includes an event management system (EMS), a real-time in-memory data structure (RIED) coupled to the EMS, the RIED for storing event information gathered by the EMS and a task management system (TMS) for ensuring that the RIED is updated by one transaction at a time. With this particular arrangement, a system for managing a large number of real-time events is provided. In one embodiment, the control system can be provided in a distributed hierarchical arrangement. The EMS of each control system can include filters which limit the amount of information provided to the next level in the hierarchy. In this manner the hierarchical control system network acts as a high volume data collector and processor. In some embodiments a level of the hierarchy can be removed spatially and/or temporally from an adjacent level in the hierarchy. This approach results in an intelligent network and also lends itself to scalability.

Abstract: An integral gas compressor and internal combustion engine. The compressor is built by converting a portion of an internal combustion engine to a compressor by removing the original engine head and valve train and replacing these with a compressor head assembly. The compressor head assembly includes compressor valves and valve chairs for holding the compressor valves in place. An inlet manifold encloses all of the valve chairs and places all of the inlet flow paths through the valve chairs in communication with a gas source. The head defines a discharge passageway therethrough which is in communication with a discharge opening. A venting system is provided to vent any gas that might build up in the compressor due to leakage past the piston rings and to transfer this vented gas to a fuel inlet of the engine, as desired. An oil viscosity sensing system is provided for sensing the oil viscosity in the crankcase and shutting down the engine when the viscosity drops below a prdetermined level.
