A miniature life-saving device for an emergency situation is disclosed. The device, for example, is useful for a trapped person under a mound of debris created by a fallen building during an earthquake or a terrorist attack. The device comprises a communication unit, a sensory unit and a power supply system. The power supply system may be a battery. The power supply system may also be a kinetic-to-electrical-energy converter. The device may be embedded in a person's clothes or accessories. The device may be operated in an extremely low power mode in a sustaining mode of operation for receiving an external signal only. The sensory unit, comprising an accelerometer/gyroscope and/or an infrared/temperature sensor, measures the survivability of the person and transmits the measured data to an external rescue station after receiving an authorized signal. The device may also be operated collaboratively with a handheld electronic device. |
