| 摘要 |
The invention relates to an electronic device comprising means for controlling operation modes, one or more subunits for which, in terms of power consumption, at least two operation modes are determinable, one of the modes being an active mode and one being a sleep mode, in which sleep mode power consumption is smaller than that in the active mode. The device comprises means for measuring a movement of the device by measuring one or more movement components, the means for controlling the operation modes being configured to keep the operation mode of one or more subunits of the device as the active mode as long as the movement of the device is unknown, change the operation mode of at least one subunit of the device from the active mode to the sleep mode when the movement is identified, keep the operation mode of one or more subunits of the device as the sleep mode as long as the movement of the device is known, change the operation mode of at least one subunit of the device from the sleep mode to the active mode when the movement changes to unknown. |
