摘要
This disclosure describes a wearable fall detection device configured to utilize several methods that facilitate monitoring a wearer of the device. The device comprises a first sensor configured to generate elevation data that represents an elevation of the device, and a second sensor configured to generate acceleration data that represents a magnitude of acceleration of the device. The device also includes a processor configured to determine, based on the elevation data, an elevation of a floor located underneath the wearer, and detect a fall affecting the wearer. Detecting a fall may be done by determining that the acceleration data satisfies a fall hypothesis condition, and determining, based on the elevation data, that the apparatus is vertically displaced from the floor by less than a threshold distance.
