Abstract: Systems, methods and computer-readable media according to the present technology enable wireless power transmitters (WPTs) to detect and characterize background signals and/or interfering noise to establish a blocker/interferer signal signature, or background signature, for a multi-signal wireless power delivery environment. The processes and methods according to present technology can be implemented as a continuous process. Alternatively, where a WPT and associated receiver device operate for signaling and wireless power transmission according to an expected or predetermined schedule, the processes described herein need not run at all times, but rather can be scheduled for only such times and durations sufficient to achieve the advantageous technical effects. In either case, the present technology provides a power-, memory-, and computation-efficient technique for both the WPT and the wireless power receiver devices (e.g., WPRs).

It is also shown that, by choosing an appropriate frequency, transmission line, and load, one can achieve the negative power factor of the (equivalent) transmission line circuit, and also make the power delivered from the source be lesser than that consumed at the load.
