Abstract: A RF transaction device is provided, which is operable to store multiple distinct data sets owned by unrelated data set owners, wherein the distinct data sets may include differing formats. The method includes the steps of: adding, by a read/write, a first data set to the RF transaction device, wherein the first data set is owned by a first owner; adding, by the read/write device, a second data set to the RF transaction device, wherein the second data set is owned by a second owner; and storing the first data set and the second data set on the RF transaction device in accordance with an owner defined format. The first and second data sets may each be stored as a Block of Binary. The first and second data sets are associated with first and second owners, respectively, and are configured to be stored independent of each other and in accordance with the particular data set storage protocol.

Abstract: A transponder-reader payment system includes a RFID reader for interrogating a transponder, and a fob including a transponder which is associated with fob data file funded by one or more funding sources. In exemplary operation, the fob identifying information may be presented to the RFID reader for completion of a transaction request. The transaction request may be provided to a fob issuer system which may process the transaction request in accordance with a funding protocol wherein the transaction request is satisfied according to a fob issuer predefined funding criteria relative to the multiple funding sources.

Abstract: A transponder-reader payment system includes a fob including a transponder, and a RFID reader for interrogating the transponder. The system may further include a personalization system for populating onto the fob and RFID reader identifying information and security and authentication keys which may be used during mutual authentication of the fob and the reader and for completing a transaction. In exemplary operation, the fob and RFID reader may be personalized, the fob may be presented to the RFID reader for interrogation, the fob and reader may engage in mutual authentication, and fob identifying information may be provided to the reader for transaction completion. In another exemplary embodiment, operation of the transponder-reader payment system may be controlled by an activation circuit. Further, the fob may be responsive to multiple interrogation signals.

Abstract: The present invention relates to a process for producing an transparent or translucent transaction device having multiple features, such as a holographic foil, integrated circuit chip, RFID circuitry, silver magnetic stripe with text on the magnetic stripe, opacity gradient, an invisible optically recognizable compound, a translucent signature field such that the RFID circuitry and signature on back of the device is visible through the device body. The invisible optically recognizable compound is an infrared ink and/or film, which can be detected by a sensor found in an ATM or device manufacturing assembly line.

Abstract: Systems and methods are configured to manage data sets associated with a transaction instrument. For example, a method is provided for facilitating the management of distinct data sets on a transaction instrument that are provided by distinct data set owners, wherein the distinct data sets may include differing formats. The method includes the steps of: adding, by a read/write, a first data set to the financial transaction instrument, wherein the first data set is owned by a first owner; adding, by the read/write device, a second data set to the financial transaction instrument, wherein the second data set is owned by a second owner; and storing the first data set and the second data set on the financial transaction instrument in accordance with an owner defined format. The first and second data sets may each be stored as a Block of Binary.

Abstract: The present invention relates to a process for producing an transparent or translucent transaction card having multiple features, such as a holographic foil, integrated circuit chip, RFID circuitry, silver magnetic stripe with text on the magnetic stripe, opacity gradient, an invisible optically recognizable compound, a translucent signature field such that the RFID circuitry and signature on back of the card is visible from the front of the card and an active thru date on the front of the card. The invisible optically recognizable compound is an infrared ink and/or film, which can be detected by a sensor found in an ATM or card assembly line.

Abstract: A transponder-reader payment system includes a fob including a transponder, and a RFID reader for interrogating the transponder. In exemplary operation, the fob identifying information may be presented to the RFID reader for completion of a transaction request. The transaction request may be provided to a fob issuer system which retrieves a value for satisfying the transaction request from a fob associated transaction data file. The issuer system may deplete the transaction data file in accordance with the transaction request and replenish the data file in accordance with fob user or fob issuer defined reload protocol.

Abstract: A transponder-reader payment system includes a fob including a transponder, and a RFID reader for interrogating the transponder. The system may further include a payment device separate and distinct from the fob, but associated with payment account mutually shared with the fob. In exemplary operation, the fob identifying information, or the payment device information, may be presented to the RFID reader for completion of a transaction request. A process server may receive the transaction request and satisfy the transaction request in accordance with a predetermined payment criteria. The process server may additionally augment a rewards account based on fob or payment device usage, thereby incenting fob usage in one instance and payment device usage in the other.

Abstract: A control for a hydraulic propeller pitch actuator includes a low power pilot valve responsive to digital electronic input signals to control movement of a hydraulic servomotor driving a higher power servovalve. Negative feedback motion is delivered from the servomotor to both the pilot valve and the servovalve.

Abstract: A large flow of high pressure fuel is supplied to a gas turbine engine by mounting a small modified vortex pump over or around a main high speed shaft. The pump includes a plurality of short, stubby impeller blades rotating at a very high speed within a fuel filled annular chamber having an axial fuel inlet and a tangential fuel outlet. A pump booster and priming system ensures the pump fills with fuel during operation.

Abstract: A metering valve (10) having a bi-directional motor (11) with a linearly-displaceable output shaft (21) in which the shaft (21) is separated from but cooperates with a bi-directionally movable piston (16) to provide a variable flow aperture (102) in a secondary flow path (12,52,74,78,76,102,100,48) extending axially through the piston (16). Flow along a primary flow path (12,18,48,14) is varied by movement of the piston (16) in response to an imbalance of opposing hydraulic forces. The imbalance in forces results from varying the foresaid flow aperture (102) by displacing the output shaft (21). However, the flow aperture (102) is only transitorily varied by displacement of the shaft (21) since the valve (10) is designed to provide a follow-up servo function by which the piston (16) is kept at a substantially constant distance from the shaft (21).

Abstract: A high speed liquid vortex pump is fitted with an electrically controlled needle valve assembly which modulates the pressure of a small portion of the working fluid which in turn moves a spool valve to regulate the high volume, high pressure pump output flow.

Abstract: A high speed liquid vortex pump is fitted with a flexible tube in the discharge throat. The flow area of the flexible tube, and thus the pump output flow rate, is varied by surrounding the tube with a pressure modulated stream of the working fluid.
