Abstract: 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.

Abstract: 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.

Abstract: 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.
