Granted: 1999-03-16
Abstract: A network system is disclosed for handling telephone requests for authorizing financial transactions between a merchant (10) and the issuer (20) of the transaction card presented for the transaction.  The network system includes an intelligent switch (14) for receiving an incoming call from a merchant.  The switch includes a Voice Response Unit (VRU) (16) which generates a request for the merchant to enter the account number of the transaction card.  The switch then determines the issuer based on data contained in the account number received from the merchant (118).  The switch then initiates a call to the issuer (120).  The switch then connects the merchant and issuer to enable the issuer to obtain additional information, directly from the merchant, for evaluating the transaction (132).  Once the information has been received, the issuer will generate an approval code which is relayed by the switch to the merchant (146, 148). The switch will also keep a record of the transaction parameters (154).  If the merchant and issuer are located in different countries, the switch can add a bilingual operator to the call for translating the verbal communications between the merchant and the issuer (232).

Granted: 2002-12-17
Abstract: An electronic control is provided for a vehicle having a main drive for propelling the vehicle, a fluid pump for providing pressurized fluid, and a supplemental drive driven by the pressurized fluid for providing supplemental propulsion for the vehicle. A main drive sensor senses the speed of the main drive and responsively produces a main drive speed signal. A supplemental drive sensor senses the speed of said supplemental drive and responsively produces a supplemental drive speed signal. A microprocessor receives the main and supplemental drive speed signals, modifies the main drive signal by a preselected amount and responsively produces a modified main drive speed signal. The microprocessor further produces an error signal responsive to a difference between the supplemental and modified main drive speed signals and processes the error signal to produce a control signal. A fluid control device receives the control signal and controls fluid flow in the supplemental drive in response to the control signal.
