Abstract:
The disclosure is related to a method and an apparatus for human fall detection with power-saving feature. In the method, a processor is set in a sleep state under a normal operating condition, and sensor data generated by a sensor unit of the apparatus worn on a person is stored in a buffer. A processor of the apparatus is woken up from a sleep state when the processor receives a collision signal, and the processor then retrieves the buffered sensor data and current sensor data. The sensor data is processed by a fall detection program. The apparatus will generate an alarm for a fall event if the sensor data meets the preset fall conditions; otherwise, the processor returns to the sleep state. The apparatus saves power by avoiding huge data calculation while staying in the sleep state until being woken up by the collision signal.

Claim (Index 13):
An apparatus for human fall detection, worn on a person under care, comprising:\n a processor; a power management unit inside the processor, used to set the processor to an awake state or a sleep state; a sensor unit, being an accelerometer or an accelerometer combined with other sensors such as gyroscope operatively coupled with the processor, used to generate sensor data correlated to the apparatus; and a memory unit, operatively coupled with the processor, used to store a fall detection program that is executed by the processor for performing a method for human fall detection comprising:\n setting the processor in a sleep state; \n storing the sensor data in a buffer, wherein the sensor data is continuously generated and the buffer is configured to store the latest limited sensor data; \n waking the processor up from the sleep state when receiving a collision signal from the sensor unit, wherein the collision signal is generated by the accelerometer when the accelerometer determines that an acceleration value calculated from current sensor data is larger than a first threshold; \n the processor comparing current acceleration value calculated from the current sensor data with a second threshold; \n the processor retrieving the sensor data stored in the buffer and the current sensor data from the sensor unit if the current acceleration value is larger than the second threshold; otherwise, the processor entering the sleep state; \n the processor comparing the sensor data stored in the buffer and the current sensor data with fall conditions set by a fall detection program; and \n generating an alarm for a fall event if the sensor data meets the fall conditions; otherwise, the processor entering the sleep state.
