Patent number: 10720789Abstract: A wireless charging system including a transmitter and a receiver. The transmitter is formed of a coil of wire that includes a first loop portion, a second loop portion, and a crossing portion. The crossing portion electrically couples the first loop portion and the second loop portion such that when current is generated in the coil, electrical current flows through the first loop portion in a different rotational direction than in the second loop portion. The receiver is formed of a ferromagnetic core and multiple (e.g., three) coils disposed about the ferromagnetic core. Each coil may be disposed about a different axis of the core such that current may be induced in at least one of the coils by a magnetic field in any direction.Type: GrantFiled: March 22, 2019Date of Patent: July 21, 2020Assignee: Apple Inc.Inventors: David W. Ritter, David B. Kosecoff, David S. Kumka, Madhusudanan Keezhveedi Sampath, Steven Charles Michalske, Tavys Q. Ashcroft, Aditya Rao, Ariadne Smith

Patent number: 10333333Abstract: A wireless charging table comprising a table top having an upper surface upon which one or more electronic devices can be placed, a wireless charging transmitter positioned under the upper surface of the table top, the wireless charging transmitter comprising a plurality of transmitter coils that define a charging region at the upper surface of the table top, and a power distribution system operatively coupled to the wireless charging transmitter, the power distribution system configured to receive power from an alternating current (AC) power source and distribute power to the wireless charging transmitter. The plurality of transmitter coils include at least a first transmitter coil comprising: a first loop portion; a second loop portion; and a crossing portion comprising overlapping conductive paths that electrically couple the first loop portion.Type: GrantFiled: June 16, 2016Date of Patent: June 25, 2019Assignee: Apple Inc.Inventors: David W.
