摘要： A method and apparatus for controlling blood withdrawal and infusion flow rate with the use of a pressure controller. The pressure controller uses pressure targets based upon occlusion limits that are calculated as a function of flow. The controller has the ability to switch from controlling withdrawal pressure to controlling infusion pressure based upon the detection of an occlusion. The controller distinguishes between partial and total occlusions of the withdrawal vein providing blood access. Depending on the nature of occlusion, the controller limits or temporarily reverses blood flow and, thus, prevents withdrawal vessel collapse or reverses blood flow to quickly infuse blood into the vessel without participation from operator.

摘要： A method and system for monitoring an evaporative purge system for malfunctions and leaks. First, a plurality of predetermined entry conditions are checked for satisfaction. If the plurality of predetermined entry conditions have been met, a flow of vapor in the evaporative purge system is determined. The evaporative purge system is then sealed from atmosphere so as to pull a vacuum on the fuel tank. The vacuum is compared to a predetermined vacuum range. If the vacuum is within the predetermined vacuum range, the vacuum is allowed to stabilize to obtain a stabilized vacuum level. A decrease in the stabilized vacuum level is determined after a predetermined amount of time to obtain a vacuum bleed-up. A vacuum bleed-up acceptance threshold is then determined based on the determined flow of vapor and the vacuum bleed-up is then compared to the vacuum bleed-up acceptance threshold. If the vacuum bleed-up exceeds the vacuum bleed-up acceptance threshold, atmosphere is provided to the evaporative purge system until stabilization. The evaporative purge system is then sealed again to create a pressure build. The pressure build is compared to a pressure threshold. Finally, a malfunction signal is generated if the pressure build is less than the pressure threshold.

摘要： An evaporative purge flow monitoring system is provided for use in a motor vehicle having an internal combustion engine, a fuel tank, and an evaporation canister in communication with the fuel tank and the engine for trapping and subsequently reusing fuel vapor dispelled from the fuel tank. The evaporative purge flow monitoring system includes a vapor management valve interposed between the engine and the evaporation canister. An Electronic Engine Control (EEC) assembly is further provided in communication with the vapor management valve and the engine wherein the EEC assembly is provided with a test logic to determine satisfactory operation of the vapor management valve. The test logic determines whether the vapor management valve is defective based on either the presence of significant fuel vapor as determined by the test logic or a change in an engine performance parameter generated within the EEC assembly without requiring a separate sensor when the vapor management valve is temporarily closed.
