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.
