A storage control apparatus can be connected to a higher level apparatus and a plurality of storage devices, and receives, from the higher level apparatus, a request to write into one of the plurality of storage devices. Here, if a storage device, among the plurality of storage devices, that has been specified as the access destination for the write request is not yet active, the storage control apparatus suspends the data involved in the write request, and writes the suspended data involved in the write request into the storage device once the storage device specified as the access destination is in a ready state.

Storage control apparatus, control method thereof, storage medium, and information processing apparatus

This information processing apparatus can operate first wireless communication in parallel with second wireless communication whose communication standard is different from that of the first wireless communication by sequentially operating the first wireless communication and the second wireless communication. In addition, this information processing apparatus determines whether or not a parallel operation in which the second wireless communication is operated in parallel with and in addition to the first wireless communication is to be performed, and decides the transmission interval of the first wireless communication based on the determination result.

Information processing apparatus, control method thereof, and storage medium

An information processing apparatus includes a first power supply unit, a first device and a second device to which power is supplied from the first power supply unit, a second power supply unit, a third device to which power is supplied from each of the first power supply unit and the second power supply unit, and a power control unit configured to perform control to switch a power supply source for the third device from the first power supply unit to the second power supply unit, and then to cause power to be supplied from the first power supply unit to the second device.

Information processing apparatus

An image forming apparatus includes a control unit configured to control writing or reading data to or from a storage unit and a cooling unit configured to cool the control unit and the storage unit, in which the control unit reads temperature information from the storage unit, and changes a timing of when to read the temperature information next from the storage unit and a cooling level of the cooling unit in conjunction with each other.

Image forming apparatus, method for controlling image forming apparatus, 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.

Power transmission device, power transmission method, and storage medium

In a wireless power supply system, a power transmitting apparatus wirelessly supplies power to an assigned power receiving apparatus. The wireless power supply system includes an assigning unit that assigns the power receiving apparatus to the power transmitting apparatus, and a determining unit that, when the assigning unit assigns a particular power receiving apparatus to a plurality of power transmitting apparatuses, determines a power supply schedule such that the plurality of power transmitting apparatuses supply the power to the particular power receiving apparatus, not simultaneously.

Wireless power supply system

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.

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.

Prevent printing if image data on preprinted sheet does not match data on at least one sheet

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.

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.

Bus control device

When a print processing apparatus is in a power saving mode, an information processing apparatus informs, for the print processing apparatus, the user that the print processing apparatus is in the power saving state. It can thus be made known to the user that the print processing apparatus is in the power saving state.

Information processing apparatus and information processing method

An information processing apparatus including a first bus connected a first bus device, a second bus connected to a second bus device, and a bus bridge connecting the first bus and the second bus. A power control unit supplies electric power to the first bus device and the bus bridge when the information processing apparatus is in an operative state, and stops power supply when the information processing apparatus is in a power saving state. A transmission control unit controls transmission of a recovery signal which is entered from the second bus device and transmitted to the power control unit to return the information processing apparatus from the power saving state to the operative state, when the information processing apparatus is in the power saving state. The power control unit resumes the power supply to the first bus device and the bus bridge in response to the recovery signal.
