摘要:
A system and a method are described for monitoring pressure imbalances in the adsorbent beds of a portable gas concentrator. Using the programmability features found in modern portable concentrators, various mitigative procedures to adjust for pressure imbalances and to predict the need for service are disclosed.

In one aspect, the present invention provides an order slicer that receives an order that to trade a financial instrument. The order associates a trading strategy with said order. The trading strategy is replaceable. In another aspect, an interface accepts a trading strategy of an order to trade a financial instrument. A transmitter transmits the trading strategy to an order slicer.

摘要:
In a trading environment that comprises buy side traders and securities brokers, a computer process capable of preventing securities brokers from receiving information irrelevant to a commission payment for a securities transaction. The process comprises means for providing an overview of commission payments for a predetermined time period, means for providing details of step-out payments for the predetermined period, means for adjusting step-in amounts and frequencies, means for providing notification that a commission payment has been stepped out and is capable of being credited, means for automatically suggesting and performing step-ins and step-outs, and means for assessing the step-outs and step-ins against a predetermined budget.
摘要:
A computer-implemented method for controlling temperature of a computer system is disclosed. The computer system contains multiple modules and at least one cooling fan. The method contains the steps of collecting thermal data from a first set of modules, calculating an initial fan speed, collecting thermal data from a second set of modules, and recalculating the fan speed to adjust cooling of modules to desired operating temperatures.
摘要:
A feed gas drying system is described for a PSA or VPSA oxygen concentrator. A membrane dryer is inserted into the feed gas path to the concentrator absorbent beds, such that the moisture in the feed gas is directed to a part of the dryer exposed to the concentrator exhaust, thus achieving efficient operation of the membrane dryer with no loss of concentrator feed gas.
摘要:
The invention provides improved methods and apparatus for control using field and control devices that provide a virtual machine environment and that communicate via an IP network. By way of non-limiting example, such field device can be an “intelligent” transmitter or actuator that includes a low power processor, along with a random access memory, a read-only memory, FlashRAM, and a sensor interface. The processor can execute a real-time operating system, as well as a Java virtual machine (JVM). Java byte code executes in the JVM to configure the field device to perform typical process control functions, e.g., for proportional integral derivative (PID) control and signal conditioning. Control networks can include a plurality of such field and control devices interconnected by an IP network, such as an Ethernet.
