  • Publication number: 20110316914
    Abstract: A device has an output circuit arranged to receive a voltage pulse, a body diode associated with the output circuit, and a detection circuit electrically coupled to the voltage pulse and the output circuit, such that when the voltage pulse transitions from high to low, the detection circuit is configured to activate the output circuit to reduce current in the body diode. A circuit to control parasitic power dissipation in an integrated circuit has a P-channel FET having a source electrode coupled to a high voltage signal source and a drain electrode coupled to a load, a body diode associated with the P-channel FET such that the body diode conducts current on a falling edge of a high voltage pulse from the high voltage signal source, and a detection circuit electrically coupled to the P-channel FET arranged to cause the P-channel FET to turn on when the body diode conducts current so as to reduce the current and lower parasitic power dissipation caused by the body diode conducting current.

  • Publication number: 20110318041
    Abstract: A calibration procedure for the synchronization of photoreceptor belt seams of tandem marking devices at system cycle-up. The procedure allows for images projected upon equivalent image panels relative to the belt seams of the tandem engines to be printed on the same sheet. The successive image panels on each belt are of relatively equal distance from the respective belt seams. Thus there is less frequency of the need to skip pitches in the printing operation to avoid either imaging on a belt seam or having the sheet arrive outside the input timing window for second engine sheet registration.

  • Publication number: 20110315031
    Abstract: A method and apparatus herein supply one or more media characteristics of a continuous media material (such as printing media) being supplied to rollers of an apparatus (such as a printing apparatus). The method and apparatus adjust the position of at least one of the rollers/shafts, relative to other rollers/shafts, based on the media characteristics to cause the media material to exhibit a target resonance frequency when being processed through the rollers. The method and apparatus can also identify excitation frequencies of vibrations produced by the apparatus as the apparatus feeds the continuous media material along the rollers and set the target resonance frequency at a value that is different from the excitation frequencies to prevent the apparatus from exciting the continuous media material at or near a resonant frequency of the processing system transporting the continuous media material.

  • Publication number: 20110320770
    Abstract: An internal buffer is provided for a DRP core. A selector SEL switches input/output destination of the DRP core between external memory and an internal buffer. Control software executed by a CPU core receives information a pipeline of configurations for a sequence of target processing and generates combinations as to whether the processing result is transferred between the configurations via the external memory or via the internal buffer as transfer manners. Next, for each manner, bandwidth and performance of the external memory used by the DRP core in the manner are calculated. The manner of the best performance satisfying a previously specified bandwidth restriction is selected among the manners and the selector SEL is switched in accordance with the manner.

    Abstract: A power supply control device including a mode switching controller, a first power supply section, a second power supply section, a third power supply section, a wiring system opening and closing unit and a controller. During the sleep mode, the first power supply section continues to supply power to a specific control system, the second power supply section shuts off its supply of power, and the third power supply section supplies power to the specific control system by a separate system to the specific control system. The wiring system opening/closing unit sets a power supply wiring system of the commercial power source to an open state or a closed state. When the third power supply section is supplying power during the sleep mode, the controller controls the wiring system opening and closing unit and sets the power supply wiring system of the commercial power supply to the open state.
