  • Publication number: 20110235097
    Abstract: An information processing device of the present invention has: a receiving section that receives a print job transmitted by a sender; a printing executing section that, when a print job received at the receiving section is a print job to which authentication information is not added, executes printing immediately, and, when a print job received at the receiving section is an authentication-added print job to which the authentication information is added, stores the print job temporarily, and executes printing on the basis of authentication of a person who carries out printing; and a notification section that, when printing of the authentication-added print job has been executed at the printing executing section, notifies the sender of the print job that printing of the print job has been executed.

  • Patent number: 8024968
    Abstract: A method detects the level of ink in a printhead reservoir by monitoring the power drawn by a thermistor positioned within the printhead reservoir. The method includes dissipating power in a thermistor in an ink reservoir, controlling the power dissipated in the thermistor to maintain the thermistor at a temperature that is a fixed differential above a reservoir temperature, measuring a parameter that corresponds to the power dissipated in the thermistor, and comparing the measured parameter to a predetermined value to detect ink in the reservoir contacting the thermistor.

  • Patent number: 8027540
    Abstract: A method begins by receiving an image of a handwritten item. The method performs a word segmentation process on the image to produce a sub-image and extracts a set of feature vectors from the sub-image. Then, the method performs an asymmetric approach that computes a first log-likelihood score of the feature vectors using a word model having a first structure (such as one comprising a Hidden Markov Model (HMM)) and also computes a second log-likelihood score of the feature vectors using a background model having a second structure (such as one comprising a Gaussian Mixture Model (GMM)). The method computes a final score for the sub-image by subtracting the second log-likelihood score from the first log-likelihood score. The final score is then compared against a predetermined standard to produce a word identification result and the word identification result is output.
