Abstract: The present invention is an apparatus for controlling a variable geometry turbocharger (VGT) in closed loop and open loop modes, and a switching mechanism for determining whether open loop or closed loop control laws should be used. In the closed loop mode, a correction factor, obtained from a pressure correction map based on engine speed and atmospheric pressure, is subtracted from the desired boost pressure to prevent overspeed of the turbocharger at lower atmospheric pressures. The actual boost pressure is then compared to the desired boost pressure after correction to obtain a boost pressure error signal. The boost pressure error signal is used as an input to a proportional integral differential control law that responsively produces a desired VGT vane position. A minimum limit on the desired VGT vane position is based on engine speed and fuel quantity, whereas a maximum allowable vane position may be a predetermined constant or function. A linearization map is used to obtain a VGT current signal that is transmitted to an actuator for moving the vane position.

Abstract: A computer-implemented method for providing risk management for online transactions. An exchange price for a foreign currency relative to a base currency is entered into a host computer. The host computer will also receive data descriptive of one or more transactions involving the foreign currency that occurred within a predetermined time period. The data will include a transaction amount. Currency is exchanged according to the entered price and the transaction amounts contained in the data. A risk exposure for the predetermined time period can be calculated based upon an aggregate amount of currency involved in transactions during the predetermined time period. The risk exposure can be based upon market data relating to the price of the foreign currency. The present invention can be implemented to capture each transaction amount that relates to a sale occurring on an e-commerce site. Currency is automatically exchanged at the price entered for the local currency. Transactions can include an online sales transaction consummated over a computerized communications network, a retail transaction between a business and a retail customer, a business to business transaction, an online auction transaction or any other quantifiable transaction.

Abstract: An apparatus for communicating with an electronic control module on an engine of a machine from a remote location is disclosed. The apparatus includes an electronic controller associated with a power supply on the electronic control module. A sensor is connected to the electronic controller for sensing an engine parameter indicative of the operating state of the engine. A communications interface for transmitting and receiving a communication signal is associated with the electronic controller. An ignition switch is connected to the power supply, such that when the ignition switch is in the off position, the electronic controller is powered down. The electronic controller is subsequently powered up if a communication signal is received from the remote location. This in turn allows a sensed engine parameter to be communicated to the remote location, and further allows machine information to be downloaded from the remote location to the electronic control module while the ignition switch remains in the off position.
