  • Patent number: 6618022
    Abstract: A self contained radio frequency identification integrated circuit (RFIDIC) switch. The RFIDIC switch includes a switch housing, a radio frequency identification integrated circuit enclosed in the switch housing and an actuator extending into the switch housing. The RFIDIC is powered by a radio frequency carrier signal. The actuator is movable to a first position and to a second position. The radio frequency identification integrated circuit transmits a signal when said actuator is in one of the positions. Movement of the actuator to the other position alters said signal.

  • Patent number: 6581058
    Abstract: One exemplary embodiment of a scalable clustering algorithm accesses a database of records having attributes or data fields of both enumerated discrete and ordered values and brings a portion of the data records into a rapid access memory. A cluster model for the data includes a table of probabilities for the enumerated, discrete data fields of the data records. The cluster model for data fields that are ordered comprises a mean and spread of the cluster. The cluster model is updated from the database records brought into the rapid access memory. At least some of the database records in the rapid access memory are summarized and stored within the rapid access memory. A criteria is then evaluated to determine if further data should be accessed from the database to further cluster data records in the database. Based on the evaluating step, additional database records in the database are accessed and brought into the rapid access memory for further updating of the cluster model.

  • Patent number: 6439454
    Abstract: A system for issuing printed documents exchangeable for value having interconnected printer and feeder modules. The printer module includes a printing station having a printhead supported for reciprocal movement in a direction transverse to the path of movement of the print medium. A sensor carried by the printhead is operative to sense and read preprinted indicia on the print medium. The feeder module includes a receptacle for storing the print medium as a continuous form. A slot is provided for enabling the insertion of print media external to the feeder module. A gate mechanism blocks the feed slot under predetermined operating conditions. A first drive mechanism is operative to feed the print medium from the receptacle towards the printing station. A severing mechanism is operative to sever the lead document from the supply.
