Abstract: A system that tracks when normal digital postage meter mail or digital processor mail is received by an addressee. The foregoing is accomplished by connecting a scanner and control software to a digital postage meter or digital processor that would read incoming digitally metered mail. Instead of printing an indicia, the scanner would read the already existing indicia and other information on the mail piece and then extract the sender data fields that are contained in the indicia or on the mail piece. The extracted mail data would be periodically uploaded to a data center. The data center would compare the extracted data with mail sender data that has previously been uploaded from sending meters and processors to determine if fraud has been committed in the production of the postal indicia.

Abstract: A digital crossbar switch designed to facilitate easy and flexible interconnection of up to 8 data ports. The device includes 8 bidirectional ports, each 8 bit wide. Interconnection of the ports is controlled by 32 stored control memory locations associated with each port. The controlling memory locations can be changed dynamically without interfering with data flow. Additional program flexibility can be achieved by providing each port with a 16 word first-in first-out data buffer. The capability to bit reverse the data on any of the ports is also provided to simplify the interconnection of busses from different architectures. The device is fully expandable to wider busses, has extensive test capability and a master reset is provided for system initialization.
