Abstract
The present invention relates to a method for controlling an electronic device (10), to an electronic device (10) as such as well as to an electronic assembly (100). A key idea of the present invention is to provide a standby state in which no operation power is consumed with respect to processes of monitoring and terminating said standby state. The standby state can at most be terminated upon receipt of a remote wakeup radio signal (WS) from which also the operation power for terminating said standby state is extracted.
Claims32
A method for controlling an electronic device comprising:
- during operation of said electronic device, controllably switching said electronic device between an active state and a standby state, wherein in said standby state no operation power is consumed at least with respect to processes of terminating or monitoring said standby state,
- terminating said standby state and entering said active state upon receipt of a remote wakeup radio signal (WS),
- extracting the operation power for terminating said standby state from said received remote wakeup radio signal (WS),
- analyzing, during or after receipt of said remote wakeup radio signal (WS), said remote wakeup radio signal (WS), and
- determining whether or not said remote wakeup radio signal (WS) contains a certain identification code (ID) assigned to said electronic device, and controllably switching said electronic device between the active state and the standby state based on the determination.
2 more elements
An electronic device comprising:
- a wakeup unit configured to controllably switch said electronic device between an active state and a standby state, wherein in said standby state no operation power is consumed at least with respect to processes of terminating or monitoring said standby state, and said wakeup unit is configured to terminate said standby state and enter said active state upon receipt of a remote wakeup radio signal (WS),
- an extracting unit configured to extract the operation power for terminating said standby state from said received remote wakeup radio signal (WS),
- an analyzing unit configured to analyze, during or after receipt of said remote wakeup radio signal (WS), said remote wakeup radio signal (WS), and to determine whether or not said remote wakeup radio signal (WS) contains a certain identification code (ID) assigned to said electronic device, wherein said wakeup unit switches said electronic device between the active state and the standby state based on the determination.
