1. An apparatus comprising:
- a wireless power receiver configured to receive a wireless power signal;
communication circuitry configured to transmit one or more change requests associated with a quantity of the wireless power signal; and
control circuitry configured to;
measure a plurality of reception levels associated with the quantity of the wireless power signal;
determine, based on the one or more change requests, a linear model of expected reception levels; and
in response to determining that at least one of the plurality of reception levels is different from the linear model, transmit a request that is configured to cause a decrease in a transmit power of the wireless power signal, a suspension in transmission of the wireless power signal for a time period, or a stop to transmission of the wireless power signal.
