Publication number: 20140108243Abstract: Processing duplicate items in image cash letter (“ICL”) return files for efficient handling. A duplicate item processing module can receive ICL return files comprising items representing duplicate electronic checks. The duplicate item processing module can determine whether the processing entity erroneously presented the item more than once. The duplicate item processing module can also determine whether the depositing institution erroneously deposited the item more than once for processing. Based on the determination of the source of the error, the duplicate item processing module can make a correction in its own records and/or forward the ICL return file with the duplicate item to the depositing institution.Type: ApplicationFiled: December 20, 2013Publication date: April 17, 2014Inventors: Benjamin T. Breeden, JR., Richard Rodrigues, Steven D. Martin, Timothy Rachek

Patent number: 8573498Abstract: A printed cash letter includes a machine-readable identifier, such as a barcode, identifying the cash letter. Upon printing, information from the identifier is read and stored in a first record. To determine whether the cash letter is a duplicate, a check presentment module compares information from the identifier with information in the first record. If information identifying the cash letter already exists in the first record, the cash letter is a duplicate. To verify cash letter printing, information identifying multiple cash letters to be printed is stored in a second record. Upon printing a portion of the cash letters, information read from identifiers on the printed cash letters is compared with information in the second record. If the second record includes information regarding a cash letter not identified in the information scanned from the barcodes, then the check presentment module identifies the cash letter as having not been printed.Type: GrantFiled: November 6, 2007Date of Patent: November 5, 2013Assignees: Federal Reserve Bank of Kansas City, Federal Reserve Bank of ChicagoInventors: Randall Lee Mueller, Richard Rodrigues, David Treptow

Patent number: 8557640Abstract: A low voltage protection device that includes a silicon substrate comprises an inner layer of a first dopant type. The device also includes a first outer layer of a second dopant type disposed adjacent a first surface of the inner layer and a second outer layer of the second dopant type disposed adjacent a second surface of the inner layer opposite the first surface. The device further includes a first mesa region disposed in a peripheral region of a first side of the low voltage protection device. The first mesa region includes a first area that includes a peripheral portion of a cathode of the low voltage protection device, the cathode formed by diffusing a high concentration of dopant species of the first type on a first surface of the silicon substrate, and a second area comprising a high concentration of diffused dopant species of the second type.Type: GrantFiled: February 1, 2013Date of Patent: October 15, 2013Assignee: Littelfuse, Inc.Inventors: Richard Rodrigues, Johnny Chen, Ethan Kuo

Patent number: 7943959Abstract: A surge protection device with small-area buried regions (38, 60) to minimize the device capacitance. The doped regions (38, 60) are formed either in a semiconductor substrate (34), or in an epitaxial layer (82), and then an epitaxial layer (40, 84) is formed thereover to bury the doped regions (38, 60). The small features of the buried regions (38, 60) are maintained as such by minimizing high temperature and long duration processing of the chip. An emitter (42, 86) is formed in the epitaxial layer (40, 84).Type: GrantFiled: August 28, 2007Date of Patent: May 17, 2011Assignee: Littelfuse, Inc.Inventor: Richard A Rodrigues

Patent number: 4629944Abstract: A starter circuit for a fluorescent tube lamp is connected between the cathode heaters of the tube to provide an initial heating current and then changes to a high impedance to ignite the tube. The circuit is fed by raw rectified a.c. and has a main thyristor requiring a high holding current to maintain the initial conduction. The current through the main thyristor sets up a voltage across a series diode which triggers a second thyristor to reduce the gate voltage of the main thyristor. The main thyristor ceases conduction when the current falls below the holding value and the inductive ballast impedance then produces a high energy striking pulse for the tube. The pulse voltage is limited to increase its duration. One embodiment generates a single pulse only each time the circuit is switched on and another embodiment produces pulses for a period of time before becoming quiescent. The main thyristor and the voltage limiting means are embodied in a monolithic semiconductor structure.Type: GrantFiled: February 29, 1984Date of Patent: December 16, 1986Assignee: Texas Instruments IncorporatedInventors: Michael J.
