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 for generating an image of a wireless power delivery environment, the method comprising:
- receiving, by multiple adaptively-phased radio frequency (RF) antennas of a wireless power delivery system, beacon signals initiated by power receiver clients in the wireless power delivery environment;
- determining a phase at which each of the beacon signals is received at the multiple adaptively-phased RF antennas to identify a phase pattern for each beacon signal;
- comparing the phase patterns to prior phase patterns to identify differences;
- and
- processing the phase differences over a period of time to generate an image or map of the wireless power delivery environment.
A system for generating an image of a wireless power delivery environment, the system comprising:
- one or more processors;
- and
- a non-transitory computer readable storage medium having instructions stored thereon, which when executed by the one or more processors of a wireless power delivery system, cause the wireless power delivery system to:
- process beacon signals initiated by power receiver clients in the wireless power delivery environment;
- determine a phase at which each of the beacon signal is received at each of multiple adaptively-phased radio frequency (RF) antennas to identify a phase pattern for each beacon signal;
- compare the phase patterns to prior phase patterns to identify differences;
- and
- process the phase differences over a period of time to generate an image or map of the wireless power delivery environment.
