The charging surface may include an ultrasonic array of transmitter sub arrays, wherein one or more of the transmitter sub arrays may be selectively activated based on the location to focus an ultrasonic beam on the adjacent ultrasonic receiver. In one example, a movement of the adjacent ultrasonic receiver may be detected and the focus of the ultrasonic beam is adjusted in response to the movement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic universal wireless charging","description":"Methods and systems may provide for detecting a location of an adjacent ultrasonic receiver of a battery powered device relative to a charging surface of a contactless charger.
