Abstract:
An electronic device includes a memory; a first processor; a second processor for which power consumption is lower than power consumption of the first processor; a communicator that communicates with an external device; and a switch that switches a connection destination of the communicator to the first processor or the second processor. The second processor is configured to, in a case in which a condition for transitioning to a power suppression state that is an operating state in which power consumption is suppressed is satisfied, connect the communicator by the switch. The first processor is configured to, in a case in which a condition for transitioning to a normal state that is a normal operating state is satisfied, connect the communicator by the switch.
Abstract:
An electronic device includes a first display; a second display for which power consumption is lower than that of the first display; a first communicator; a second communicator for which power consumption is lower than that of the first communicator; a memory; a first processor; a second processor for which power consumption is lower than that of the first processor; and an operation acquirer to, when an operation from a user is acquired, send a wake-up signal that causes the first processor to recover from a sleep state in which power consumption is suppressed to a normal state. The first processor is configured to, when a condition for transitioning to a power suppression state is satisfied, send a power suppression notification to the second processor, stop displaying by the first display and communicating by the first communicator, and transition to the sleep state, and to, when the wake-up signal is received from the second processor or the operation acquirer, recover to the normal state from the sleep state, and start displaying by the first display and communicating by the first communicator. The second processor is configured to, when the second processor receives the power suppression notification from the first processor, start displaying by the second display and communicating by the second communicator, and to, when a condition for transitioning to the normal state is satisfied, send the wake-up signal to the first processor, and stop the displaying by the second display and the communicating by the second communicator.
Abstract:
An information processing apparatus includes a first processor, a second processor and a positioning processor. The second processor consumes a reduced amount of power compared to the first processor during an operation. The positioning processor receives radio waves from positioning satellites and converts the radio waves into positioning data. The second processor controls the positioning processor. The second processor stores the positioning data received from the positioning processor. The second processor transfers the stored positioning data to the first processor at a timing determined in accordance with an operating condition of the first processor.
Abstract:
An information processing apparatus includes: a communication unit that performs wireless communication with an external apparatus; a first control unit that switches between a normal state and a low electric power consumption state that suppresses electric power consumption to less than the normal state; and a second control unit that operates at lower electric power consumption than the first control unit, in which the information processing apparatus controls a connection state of the communication unit with the first control unit and the second control unit, based on a state of the information processing apparatus.
Abstract:
A display device includes a display, a touch panel and a controller. The display includes a plurality of display panels laminated on one another. The touch panel is provided on a screen of the display and accepts touch operation. The controller determines with respect to which display panel among the plurality of display panels the touch operation is carried out, and carries out a process corresponding to operation content of the touch operation on the determined display panel.

An electronic device includes: a magnetic first nonvolatile memory that has no movable element; a nonmagnetic second nonvolatile memory; and a processor. The processor is configured to execute processing including: stopping writing data onto the first nonvolatile memory but writing the data onto the second nonvolatile memory in response to determining, based on magnetic field information regarding a magnetic field around the electronic device, that the electronic device is on a magnetic field equal to or stronger than a reference magnetic field strength in writing the data onto the first nonvolatile memory; and writing the data of the second nonvolatile memory onto the first nonvolatile memory in response to determining, based on the magnetic field information, that the electronic device is not on the magnetic field and that the data is on the second nonvolatile memory.
Abstract:
An electronic device includes first and second processors, and first and second display units. While the first and second processors cooperate with each other and perform a display operation including a time display, the first processor can be set to a normal mode, a low power mode in which a power consumption is lower than a power consumption in the normal mode, or a pause mode in which a power consumption is lower than the power consumption in the low power mode, and the first processor is stopped. In the normal or low power modes, the first processor controls such that the first display unit displays a time, and the second processor controls such that the second display unit does not display a time. In the pause mode, the first display unit is turned off, and the second processor controls such that the second display unit displays a time.
