  • Publication number: 20060279768
    Abstract: An approach is provided for securely printing electronic documents using a portable media. The approach is applicable to a wide variety of contexts and implementations and includes secure direct printing of electronic documents, secure direct printing of electronic documents with remote user authentication and secure printing of electronic documents with remote data management. The particular information provided on the portable media varies, depending upon the implementation. Furthermore, the approach provides varying degrees of security and may be used in conjunction with conventional printing of electronic documents.

  • Patent number: 7032148
    Abstract: A method and apparatus for selectively masking off unknown (‘x’) captured scan data in first selected scan cells 220 from propagating through the scan chains 221 for test, debug, diagnosis, and yield improvement of a scan-based integrated circuit 207 in a selected scan-test mode 232 or selected self-test mode. The scan-based integrated circuit 207 contains a plurality of scan chains 221, a plurality of pattern generators 208, a plurality of pattern compactors 213, with each scan chain 221 comprising multiple scan cells 220, 222 coupled in series. The method and apparatus further includes an output-mask controller 211 and an output-mask network 212 embedded on the scan data input path of second selected scan cells 222, or a set/reset controller controlling selected set/reset inputs of second selected scan cells. A synthesis method is also proposed for synthesizing the output-mask controller 211 and the set/reset controller.

  • Publication number: 20050225795
    Abstract: An approach for automatically customizing printer drivers generally includes installing a generic printer driver on a client. The client is configured to allow communications between the generic printer driver and a printing device. The generic printer driver automatically retrieves configuration data from the printing device and stores the configuration data on a non-volatile storage. The configuration data indicates one or more attributes of the printing device and allows data to be printed to the printing device via the generic printer driver. The approach allows a generic printer driver to be used with many different printing devices, thereby reducing development costs and installation overhead.

  • Publication number: 20030109942
    Abstract: An interface for connecting one of a plurality of industrial machines having different data format and storage configurations to a communications medium for remote monitoring and control, includes a programmable apparatus having a memory for storing data in predetermined locations and in a predetermined format, and for storing configuration information relating to the at least one of the machines; a configurable electrical interface responsive to the configuration information for receiving machine data from the machine and sending data to the machine; a data translator responsive to the configuration information, receiving data from the interface and transforming the data to the predetermined format; a processor responsive to the configuration information for reading data from and writing data to the predetermined locations in the memory; and a communications port connected to the communications medium.
