Patent number: 11950713Abstract: Systems disclosed herein are directed to a display stand unit for a retail environment. The display stand unit includes a base having an interior and a display stand. The display stand includes a stem that connects to and extends upwardly from the base and a receiving surface that is suspended above and spaced away from the base by the stem. The receiving surface is configured to releasably hold an electronic device above and spaced away from the base. The display stand unit further includes a security cable that extends out from the base. The security cable is configured to attach to the electronic device to movably secure the electronic device to the base. The display stand unit further includes a retractor disposed within the interior of the base and connected to the security cable. The retractor automatically retracts the security cable.Type: GrantFiled: February 4, 2022Date of Patent: April 9, 2024Assignee: Apple Inc.Inventors: David Samuel Kumka, Clayton R. Woosley, Daniel S. Foster, Eric Weijia Wang, Gregory R. Ritter, Joshua Adams, Christopher Hu, Priya K. Nambiar

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
