Patent ID: 10866302

Abstract:
Methods, apparatus and systems for wireless inertial measurement are described. In one embodiment, a described system comprises a transmitter transmitting a wireless signal, a receiver, and a processor. The receiver is configured for: receiving the wireless signal through a wireless multipath channel, and extracting a plurality of time series of channel information (TSCI) of the wireless multipath channel from the wireless signal. One of the transmitter and the receiver is a stationary device, and the other one is a moving device moving with an object. The processor is configured for: determining that a first channel information (CI) at a first time of a first TSCI associated with a first antenna of the moving device matches a second CI at a second time of a second TSCI associated with a second antenna of the moving device, wherein both the first TSCI and the second TSCI are associated with a same antenna of the stationary device; computing at least one movement parameter and a spatial-temporal information (STI) of the moving device; and tracking at least one of the object and the moving device based on the STI.
