Abstract:
Methods, apparatus and systems for detecting and monitoring vital signs and other periodic motions of an object are disclosed. In one example, a system for monitoring object motion in a venue is disclosed. The system comprises a transmitter, a receiver, and a vital sign estimator. The transmitter is located at a first position in the venue and configured for transmitting a wireless signal through a wireless multipath channel impacted by a pseudo-periodic motion of an object in the venue. The receiver is located at a second position in the venue and configured for: receiving the wireless signal through the wireless multipath channel impacted by the pseudo-periodic motion of the object in the venue, and obtaining at least one time series of channel information (TSCI) of the wireless multipath channel based on the wireless signal. The vital sign estimator is configured for: determining that at least one portion of the at least one TSCI in a current sliding time window is associated with the pseudo-periodic motion of the object in the venue, and computing a current characteristics related to the pseudo-periodic motion of the object in the current sliding time window based on at least one of: the at least one portion of the at least one TSCI in the current sliding time window, at least one portion of the at least one TSCI in a past sliding time window, and a past characteristics related to the pseudo-periodic motion of the object in the past sliding time window.

Claim (Index 27):
The method of  claim 25 , further comprising:\n determining a timestamp associated with each channel information of the at least one TSCI; correcting timestamps of all channel information of a particular portion of the at least one TSCI in the current sliding time window so that the corrected timestamps of time-corrected channel information are uniformly spaced in time; and performing an operation on the time-corrected channel information with respect to the corrected timestamps, wherein the current characteristics related to the pseudo-periodic motion of the object is computed based on an output of the operation, wherein the operation comprises at least one of: preprocessing, processing, post-processing, filtering, linear filtering, nonlinear filtering, low-pass filtering, bandpass filtering, high-pass filtering, matched filtering, enhancement, restoration, de-noising, spectral analysis, frequency transform, inverse frequency transform, linear transform, nonlinear transform, feature extraction, machine learning, recognition, labeling, training, clustering, grouping, sorting, thresholding, peak detection, comparison with time-corrected channel information of another portion of another time series of channel information in another sliding time window, similarity score computation, vector quantization, compression, encryption, coding, storing, transmitting, representing, merging, combining, fusion, linear combination, nonlinear combination, and splitting.
