Wake-up system and method for an electronic apparatus

摘要

An electronic device may include a wireless transceiver for establishing a wireless interface with a wireless transceiver of another device. The electronic device may further include a wake-up assembly including a permanent magnet that generates a magnet field and a sensor that outputs a signal corresponding to sensed magnetic field. A control assembly of the electronic device may be configured to control at least one of activation or deactivation of the wireless transceiver when the output from the sensor indicates that the magnetic field of the permanent magnet has been disturbed by presence of a magnet external to the electronic device.
