SYSTEM, METHOD AND APPARATUS FOR CHARGING A WORN DEVICE
A wearable device (10) has an internal rechargeable power source (112) for supplying power to internal circuitry of the device. An external rechargeable battery pack (30) is physically and electrically interfaced to the wearable device and provides power to recharge the internal rechargeable power source while the device is being worn, thereby eliminating the need to connect the wearable device directly to a source of electricity using wires. The rechargeable battery pack is recharged in a charging station (68) connected to a source of electricity .
