Apparatus, systems and methods for fall-down detection based on a wireless signal
First Claim
1. A system 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:
- a transmitter located at a first position in the venue and configured for transmitting a wireless signal through a wireless multipath channel impacted by the transient motion of an object in the venue;
a receiver located at a second position in the venue and configured for;
receiving the wireless signal through the wireless multipath channel impacted by the transient motion of the object in the venue, andobtaining a time series of channel information (CI) of the wireless multipath channel based on the wireless signal; and
a transient motion monitor configured for;
monitoring the transient motion of the object based on the time series of CI, andtriggering a response action based on the monitored transient motion of the object.

Abstract
Apparatus, systems and methods for detecting and monitoring fall-down actions and other transient motions are disclosed. In one example, a system for monitoring a transient motion in a venue is disclosed. The system comprises a transmitter, a receiver, and a transient motion monitor. The transmitter is located at a first position in the venue for transmitting a wireless signal through a wireless multipath channel impacted by the transient motion of an object in the venue. The receiver is located at a second position in the venue for: receiving the wireless signal through the wireless multipath channel, and obtaining a time series of channel information (CI) of the wireless multipath channel based on the wireless signal. The transient motion monitor is configured for: monitoring the transient motion based on the time series of CI, and triggering a response action based on the monitored transient motion.

29. 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.

30. 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.
