Abstract
Techniques are described herein for imaging static or semi-static objects in a wireless power delivery environment and tracking non-static objects contained therein. More specifically, embodiments of the present disclosure describe techniques for determining the relative locations and movement of non-static objects in a wireless power delivery environment. Additionally, the techniques describe methods and system for generation of motion-based maps such as heat (or dwell maps) and flow maps.
Claims20
A method comprising:
- determining a first phase pattern at which a signal is received by a plurality of antennas from a transmitter at a first time;
- determining a second phase pattern at which the signal is received by the plurality of antennas from the transmitter at a second time;
- identifying a difference between the first phase pattern and the second phase pattern;
- and
- determining presence or absence of movement of the transmitter based on the difference.
A system comprising a processor configured to:
- determine a first phase pattern at which a signal is received by a plurality of antennas from a transmitter at a first time;
- determine a second phase pattern at which the signal is received by the plurality of antennas from the transmitter at a second time;
- identify a difference between the first phase pattern and the second phase pattern;
- and
- determine presence or absence of movement of the transmitter based on the difference.
One or more non-transitory computer readable media having program instructions stored thereon that, when executed by a computing device, cause a machine to:
- determine a first phase pattern at which a signal is received by a plurality of antennas from a transmitter at a first time;
- determine a second phase pattern at which the signal is received by the plurality of antennas from the transmitter at a second time;
- identify a difference between the first phase pattern and the second phase pattern;
- and
- determine presence or absence of movement of the transmitter based on the difference.
