Patent application number | Description | Published |
20090276650 | INFORMATION PROCESSING APPARATUS AND METHOD FOR CONTROLLING INFORMATION PROCESSING APPARATUS - An information processing apparatus includes a storage unit configured to store data, a supply unit configured to supply electric power to the storage unit, a determination unit configured to determine whether to cause the information processing apparatus to operate in a power saving mode, a measuring unit configured to measure an elapsed time after a power source of the information processing apparatus is turned on and until the determination unit determines to cause the information processing apparatus to operate in a power saving mode, and a control unit configured to control the supply unit to decrease electric power supplied from the supply unit to the storage unit at a timing determined based on the elapsed time and a predetermined reference time, in case that the determination unit determines to cause the information processing apparatus to operate in a power saving mode. | 11-05-2009 |
20090313408 | BUS CONTROL DEVICE - A bus control device includes a multiplexer which connects a ROM controller to a common bus when a ROM mode is set and which connects a PCI controller to the common bus when a PCI mode is set. The bus control unit further includes a bus switch which disconnects a PCI bus from the common bus when the ROM mode is set and which connects the PCI bus to the common bus when the PCI mode is set. | 12-17-2009 |
20110032559 | DATA PROCESSING APPARATUS, METHOD FOR CONTROLLING DATA PROCESSING APPARATUS, AND INFORMATION PROCESSING APPARATUS - A method is provided that restricts execution of a job where a finished sheet which is specified in a job, and another finished sheet that is fed, do not match each other. The method for controlling a data processing apparatus for causing a post-processing apparatus to execute post-processing on a print product output by executing printing based on print data received from an information processing apparatus includes inputting image data generated by reading a sheet to be post-processed, receiving checking data for checking an image of the sheet, and restricting, if the checking data does not match the input image data, execution of the post-processing. | 02-10-2011 |
20110179961 | PRINTING APPARATUS, PRINTING METHOD, AND STORAGE MEDIUM CAPABLE OF MAKING QUALITY INSPECTION - A printing apparatus capable of improving the printing quality and at the same time reducing the printing failure occurrence rate. An inspection controller of the printing apparatus causes an image reader to read plural pages, which are printed on a sheet according to first image data from a host computer, and generates second image data based on a result of the reading. The inspection controller detects, based on the first and second image data, an amount of printing displacement on each page printed on the sheet, and determines whether the detected amount of printing displacement on each page falls within an allowable range defined by an allowable value. If a saddle-stitching book-binding process is specified in print settings, the allowable value is changed between particular pages where there is an image in a peripheral area around a folded sheet portion and other pages. | 07-28-2011 |
20120166850 | INFORMATION PROCESSING APPARATUS AND METHOD FOR CONTROLLING INFORMATION PROCESSING APPARATUS - An information processing apparatus includes a storage unit configured to store data, a supply unit configured to supply electric power to the storage unit, a determination unit configured to determine whether to cause the information processing apparatus to operate in a power saving mode, a measuring unit configured to measure an elapsed time after a power source of the information processing apparatus is turned on and until the determination unit determines to cause the information processing apparatus to operate in a power saving mode, and a control unit configured to control the supply unit to decrease electric power supplied from the supply unit to the storage unit at a timing determined based on the elapsed time and a predetermined reference time, in case that the determination unit determines to cause the information processing apparatus to operate in a power saving mode. | 06-28-2012 |
20130132747 | INFORMATION PROCESSING APPARATUS WITH POWER CONTROL UNIT, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING CONTROL PROGRAM THEREFOR - An information processing apparatus that is capable of reducing power consumption. A power supply unit supplies electric power to devices including first and second devices of the apparatus. A power-state-switching unit switches a power state of the apparatus among a first power state in which the power supply unit supplies power to the devices, a second power state in which the power supply unit does not supply power to the first device without supplying power from a secondary battery to the devices, and a third power state in which the secondary battery supplies power to the second device. A control unit controls so that the secondary battery is charged by the power supplied from the power supply unit in the first power state, and to control so that the secondary battery is not charged by the power supplied from the power supply unit in the second and third power states. | 05-23-2013 |
20130159736 | ELECTRONIC APPARATUS WITH LOW POWER CONSUMPTION, AND CONTROL METHOD AND STORAGE MEDIUM THEREFOR - An electronic apparatus in which an AC power source and a secondary battery are used in combination and which is capable of reducing power consumption. Among plural apparatuses that constitute an image processing apparatus serving as an electronic apparatus, part of the plural apparatuses can be supplied with power from a secondary battery. In a case where power use efficiency attained when required power for all apparatuses to be operated, among the part of the plural apparatuses, is supplied from the secondary battery is higher than conversion efficiency of an AC power unit attained when the required power is supplied from the AC power unit, FETs are controlled such that power is supplied from the secondary battery to the apparatuses to be operated. | 06-20-2013 |
20140306547 | POWER TRANSMISSION DEVICE, POWER TRANSMISSION METHOD, AND STORAGE MEDIUM - A power transmission device that wirelessly supplies power with a power receiving device includes a power transmission unit configured to wirelessly transmit power to a power receiving device, a receiving unit configured to receive a receiving power amount from the power receiving device, an evaluation unit configured to compare a reference value of the power receiving device and the receiving power amount and evaluate a transmission efficiency of power to the power receiving device based on a comparison result, and a transmission unit configured to transmit an evaluation result by the evaluation unit to the power receiving device. | 10-16-2014 |
