An apparatus to transmit wireless power comprises a transmit antenna, a driver, a sensing circuit, and a control circuit. The transmit antenna generates a wireless field to charge devices. The driver powers the transmit antenna for generation of the wireless field. A power level of the wireless field is based on a power level of the driver. The sensing circuit senses wireless power received at the transmit antenna and generates a monitoring signal based on the sensed wireless power received at the transmit antenna. The control circuit controls the power level or inhibits the driver from powering the transmit antenna when the monitoring signal indicates that the transmit antenna is receiving wireless power from a foreign antenna."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection device and method for power transmitter","description":"Aspects of a protection circuit and method are disclosed.
