Abstract

A method and system are disclosed for safely and efficiently delivering a beam of wireless power from a transmitter to at least one receiver. A delta signal is generated by repeatedly calculating the power difference between the power of the beam emitted by the transmitter and the amount of power received at the receiver. The system dynamically generates a time delay that is shorter in duration than a maximum exposure duration associated with a safe exposure duration for the power level of the delta signal. If the time delay is exceeded, the system alters an operational parameter of the system, such as terminating the beam. Due to limitations in building a perfect timing system, the system is built to be more sensitive to time delays with longer safe exposure durations, while large delta signals with short safe exposure durations are responded to immediately without significant consideration for the time delay.
