SYSTEM AND METHOD FOR CHANGING AN ACTIVATION STATE OF AN ELECTRONIC DEVICE USING ACOUSTIC SIGNALS

摘要

The disclosure relates to a system and method for unlocking and unlocking activation to a device. An activation management system of an embodiment comprises: a sensor providing an output signal when the sensor is activated by an acoustic signal; and an activation module receiving the output signal from the sensor. The activation module evaluates the output signal against a pattern and to change an activation state of the device if the output signal completes a match for the pattern.
