Apparatus, systems and methods for fall-down detection based on a wireless signal

A method implemented on a machine having a processor, a memory communicatively coupled with the processor and a set of instructions stored in the memory for monitoring a transient motion in a venue, comprising:

• receiving a wireless signal through a wireless multipath channel impacted by the transient motion of an object in the venue;
• obtaining a time series of channel information (CI) of the wireless multipath channel based on the wireless signal;
• monitoring the transient motion of the object based on the time series of CI;
• and
• triggering a response action based on the monitored transient motion of the object.

A monitor of a motion monitoring system, comprising:

• a processor;
• a memory communicatively coupled with the processor;
• and
• a set of instructions stored in the memory which, when executed, causes the processor to perform:
• obtaining a time series of channel information (CI) of a wireless multipath channel from a receiver of the motion monitoring system, wherein the receiver extracts the time series of CI from a wireless signal received from a transmitter of the motion monitoring system through the wireless multipath channel impacted by a transient motion of an object in a venue,
• monitoring the transient motion of the object based on the time series of CI, and
• triggering a response action based on the monitored transient motion of the object.

A receiver of a motion monitoring system, comprising:

• a wireless circuitry configured to receive a wireless signal through a wireless multipath channel impacted by a transient motion of an object in a venue, wherein the wireless signal is transmitted by a transmitter of the motion monitoring system;
• a processor communicatively coupled with the wireless circuitry;
• a memory communicatively coupled with the processor;
• and
• a set of instructions stored in the memory which, when executed, causes the processor to obtain a time series of channel information (CI) of the wireless multipath channel based on the wireless signal, wherein:
• the time series of CI is to be used by a transient motion monitor of the motion monitoring system to monitor the transient motion of the object and trigger a response action based on the monitored transient motion.
