  • Patent number: 8239594
    Abstract: A modular card issuance system comprises a plurality of sequentially ordered modules configured such that each module is in electrical communication with its adjacent modules. This system also comprises a main controller that is in electrical communication with each of the modules. Upon power-up of the system and without assistance from the main controller, each module determines its own identity, its relative position among the plurality of modules and the total number of modules in the system. This information is then reported to the main controller upon request from the main controller.

  • Patent number: 5266781
    Abstract: Standardized card processing modules are mechanically and electrically interconnected to form an application specific card personalization machine. A controller is coupled to a communication bus which permits the controller to download card data to the card processing modules and to upload status information from the card processing modules. Each one of the card processing modules performs a different encoding or personalization function under the control of a local processor.

  • Patent number: 5204669
    Abstract: The present invention provides a method and apparatus for dynamically assigning addresses and determining the configuration of a plurality of programmable function modules connected to an electrical conductor, such as a serial bus. The programmable function modules are electrically interconnected by a control line in a point-to-point connection between one another. A programmable controller will first transmit an enabling signal on the control line and then will transmit predetermined addressing information on the serial bus. The first function module will then access the serial bus and retrieve the addressing information, assign itself a unique address as determined by the addressing information, modify the addressing information in a predetermined manner, return the modified addressing information to the serial bus, and enable the adjacent function module on the control line. Each function module connected to the serial bus will be assigned an address in a similar fashion.
