  • Patent number: 8199355
    Abstract: A document management software is executed in print control device connectable via a network to an information processing device that sends an instruction and document thereto. The software includes: a step of determining if a non-native document is selected, wherein the non-native document is stored in a detachable memory connected to the print control device; a step of sending to the information processing device the selected non-native document so as to convert the non-native document into a native document; and a step of receiving the converted native document from the information processing device for printing, wherein the native document is printable document.

  • Patent number: 8099676
    Abstract: A logon management software application is executed in a print control device (4) connectable to an information processing device (1), and performs the steps of: detecting if a hardware keyboard (38) is connected to the print control device during a logon process; displaying on a display (35) a first logon GUI for using the connected hardware keyboard if the connection of the hardware keyboard is detected; displaying on the display a second logon GUI, different to the first logon GUI, if the connection of the hardware keyboard is not detected; and controlling a logon of the print control device based on information entered into the first and/or second logon GUI dependent on whether the connection of the hardware keyboard is detected during at least part of the logon process.

  • Patent number: 6389392
    Abstract: A method and apparatus for pattern recognition comprising comparing an input signal representing an unknown pattern with reference data representing each of a plurality of pre-defined patterns, at least one of the pre-defined patterns being represented by at least two instances of reference data. Successive segments of the input signal are compared with successive segments of the reference data and comparison results for each successive segment are generated. For each pre-defined pattern having at least two instances of reference data, the comparison results for the closest matching segment of reference data for each segment of the input signal are recorded to produce a composite comparison result for the said pre-defined pattern. The unknown pattern is the identified on the basis of the comparison results. Thus the effect of a mismatch between the input signal and each instance of the reference data is reduced by selecting the best segments from the instances of reference data for each pre-defined pattern.
