20150084892 | CONTROL DEVICE, DISPLAY DEVICE, CONTROL METHOD AND PROGRAM PRODUCT - A control device according to embodiments may control update of a target region in an electronic paper. The device may comprise a divider unit, a manager unit and an update instruction unit. The divider unit may be configured to divide the target region into a plurality of sub-regions. The manager unit may be configured to configure an update start timing of each sub-region so that flashings occurring at updating of the sub-regions appear at different timings. The update instruction unit may be configured to instruct to execute an update process of each sub-region according to the update start timings. | 03-26-2015 |
20150089261 | INFORMATION PROCESSING DEVICE AND SEMICONDUCTOR DEVICE - According to an embodiment, an information processing device includes a memory device, one or more peripheral devices, a processor, and a state controller. The processor is able to change between a first state, in which a command is executed, and a second state, in which an interrupt is awaited. When the processor enters the second state and if an operation for data transfer is being performed between at least one of the peripheral devices and the memory device, the state controller switches the information processing device to a third state in which power consumption is lower as compared to the first state. If the operation for data transfer is not being performed between any of the peripheral devices and the memory device, the state controller switches the information processing device to a fourth state in which power consumption is lower as compared to the third state. | 03-26-2015 |
20150228047 | DATA PROCESSING DEVICE, SEMICONDUCTOR DEVICE, DISPLAY DEVICE, CONTROL METHOD AND PROGRAM PRODUCT - A data processing device according to embodiments may comprise: a processor that reconstructs a plurality of update requests for updating at least a part of a display into one or more update requests, or determine that the plurality of the update requests are unnecessary; and an update instruction unit that instructs to execute update processes of the display using the reconstructed one or more update requests. | 08-13-2015 |
20150261283 | COMMUNICATION DEVICE - According to an embodiment, a communication device includes a register and a controller. The register receives data from an external device via an input data line. In a first state in which the communication device is able to receive the data, when a condition in which the data is not sent to the input data line continues for a certain period of time, the controller controls to switch state of the communication device to a second state in which power consumption is less than in the first state. | 09-17-2015 |
20150262715 | INFORMATION PROCESSING DEVICE, SEMICONDUCTOR CHIP, INFORMATION PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT - According to an embodiment, an information processing device includes a data obtaining unit and a data storage controller. The data obtaining unit is configured to obtain data measured by a sensor. The data storage controller is configured to store the data obtained by the data obtaining unit in a first memory of volatile nature when a sampling interval indicating an interval at which the data obtaining unit obtains the data is equal to or smaller than a threshold value. The data storage controller is configured to store the data obtained by the data obtaining unit and the data stored in the first memory in a second memory of nonvolatile nature when the sampling interval exceeds the threshold value. | 09-17-2015 |
20150271817 | COMMUNICATION DEVICE, WIRELESS COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND COMPUTER PROGRAM PRODUCT - According to an embodiment, a communication device for dynamically building a network includes a first receiver and a first transmitter. When the communication device attempts to newly join the network, the first receiver waits for reception of a first beacon containing information for joining the network from another communication device already joining the network for a predetermined first period. When the communication device is already joining the network, the first transmitter determines a schedule indicating timings at which a plurality of communication devices already joining the network transmit first beacons so that intervals at which the communication devices transmit the first beacons in the network as a whole do not exceed the first period and transmit the first beacon according to the schedule. | 09-24-2015 |
20160085292 | ELECTRONIC DEVICE - According to an embodiment, an electronic device includes functional modules and converters. A processor includes a memory storing state information on the state of the processor. Each converter converts the power-supply voltage to a rated voltage for functional modules, and supplies the rated voltage to at least one functional module. When the processor switches to the standby state, a controller stops the supply of the rated voltages to the functional modules except a state holding unit, a receiving unit, and the controller; and stops the operations of the converters not connected to the state holding unit, the receiving unit, and the controller. The state holding unit holds the state information before the processor switches to the standby state. The receiving unit receives a return signal representing the trigger for returning from the standby state. The state holding unit, the receiving unit, and the controller are connected to the same converter. | 03-24-2016 |
