摘要： A method is provided for a wireless communication device containing at least a main processor for data processing, and a transmitter and a receiver for wireless communication. The method includes providing power to the main processor using a power source via a power switch, performing device initialization of the wireless communication device, and determining whether the wireless communication device recovers from a power-down standby mode, where the power source is disconnected to the main processor such that the main processor does not consume power from the power source. Further, the method includes recovering device states based on information stored on a non-volatile storage when it is determined that the wireless communication device recovers from a power-down standby mode. The method also includes reporting device status including at least battery level of the wireless communication device to an external server based on configuration information on the wireless communication device.

摘要： The present disclosure provides a method and a system for fall detection. Measurement signals are received from a plurality of sensors to monitor user activities, the plurality of sensors including a motion sensor for collecting motion information and a biomedical sensor for collecting physiological information. According to a signal processing sequence, whether the measurement signals meet multiple qualifying conditions for a fall incident is determined. The multiple qualifying conditions include: a condition evaluating at least the motion information, and a condition evaluating at least the physiological information. The method further includes: when the measurement signals do not meet the multiple qualifying conditions, continuing to monitor the user activities; and when the measurement signals meet the multiple conditions, determining that a fall incident has occurred, and sending an alert message to a designated contact.
