Audio pattern matching for device activation |
摘要 |
A system and method are disclosed for activating an electric device from a standby power mode to a full power mode. The system may include one or more microphones for monitoring audio signals in the vicinity of the electric device, and a standby power activation unit including a low-power microprocessor and a non-volatile memory. Audio captured by the one or more microphones is digitized and compared by the microprocessor against predefined activation pattern(s) stored in the non-volatile memory. If a pattern match is detected between the digital audio pattern and a predefined activation pattern, the electric device is activated. |
