Abstract:
Apparatus, systems and methods for recognizing and classifying events in a venue based on a wireless signal are disclosed. In one example, a disclosed system comprises a first transmitter, a second transmitter, at least one first receiver, at least one second receiver, and an event recognition engine, in the venue. The first transmitter transmits a training wireless signal through a wireless multipath channel impacted by a known event in the venue in a training time period associated with the known event. Each first receiver receives asynchronously the training wireless signal, and obtains, asynchronously based on the training wireless signal, at least one time series of training channel information of the wireless multipath channel between the first receiver and the first transmitter. The second transmitter transmits a current wireless signal through the wireless multipath channel impacted by a current event in a current time period associated with the current event. Each second receiver receives asynchronously the current wireless signal, and obtains, asynchronously based on the current wireless signal, at least one time series of current channel information of the wireless multipath channel between the second receiver and the second transmitter. The event recognition engine trains a classifier based on the training channel information; and apples the classifier to: classify the current channel information and associate the current event with at least one of: a known event, an unknown event and another event.

Claim (Index 16):
The method of  claim 15 , further comprising:\n computing how many times each known event achieves a smallest mismatch cost; and associating the at least one first section with at least one of:\n a known event that achieves the smallest mismatch cost for most times, \n a known event that achieves a smallest overall mismatch cost, wherein an overall mismatch cost is a weighted average of at least one mismatch cost associated with the at least one first section, \n a known event that achieves a smallest cost based on another overall cost, and \n an unknown event, \n wherein the at least one first section is associated with the unknown event in at least one of the following situations:\n no event achieves a mismatch cost lower than a first threshold T 1  in a sufficient percentage of the at least one first section, and \n no event achieves an overall mismatch cost lower than a second threshold T 2 .
