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 7):
A method for human fall detection, comprising:\n setting a processor to a sleep state; storing sensor data generated by a sensor unit of an apparatus worn on a person under care in a buffer, wherein the sensor data is continuously generated and the buffer is configured to store the latest limited sensor data; waking the processor up from the sleep state when receiving a collision signal from the sensor unit, wherein the collision signal is generated by an accelerometer when the accelerometer determines that an acceleration value calculated from current sensor data is larger than a first threshold; the processor comparing current acceleration value calculated from the current sensor data with a second threshold; the processor retrieving the latest previous 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; 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 generating an alarm for a fall event if the sensor data meets the fall conditions; otherwise, the processor entering the sleep state.
