Abstract: A coil-in-coil structure (100) is formed within two devices (106, 108). The coil-in-coil structure (100) enables both wireless charging and secure pairing between the two devices (106, 108). The coil-in-coil structure (100) permits expanded wireless functionality using a single transmit coil (104) at a host radio device (108) and a receive coil (102) at an accessory device (106). A plurality of different accessory devices (606) can be interchangeably accommodated via a single host port (114) of the radio device (108).

Abstract: A system, method, and apparatus for charging primary battery-powered devices and battery-powered accessories tethered to the primary devices are disclosed. The two devices may include batteries of different types having different nominal voltages. A processing unit on the primary device may obtain state-of-charge information and other operating parameters of the batteries and may determine when to provide power to the accessory to charge its battery. The primary device may select its own battery, power provided by a charger to which it is coupled, or conditioned power as the source of charging energy provided to the accessory to charge its battery. Processing units on the two devices may adjust charging parameters to perform energy balancing while the batteries are simultaneously charged, based on operating parameters of the batteries, operating contexts of the devices, a charging prioritization scheme, or a current distribution scheme.
