Abstract: Aspects of the present disclosure involve a system and method for charging a device. The current disclosure also presents a cradle which can be used as an interface for communicating with external computing systems and power charging systems. In one embodiment, the cradle is used to down convert a high powered signal from a power charging system for use to charge a device such as a wearable. In another embodiment, the cradle is used to communicate with and external computing system for device upgrades and maintenance.

Abstract: Aspects of the present disclosure involve a system and method for communicating with multiple devices using a single radio. In one embodiment, a wearable device is configured to use a single radio for near-field and far-field communications. In another embodiment, the wearable device is configured to include an adaptable radio filter that enables the near-field and far-field transmission. The wearable device may further include an adaptable radio IC whose physical layer parameters are adjusted based in part of the transmission mode of a received signal.

Abstract: A modulation amplifier includes a signal converter, a summator and a plurality of high frequency stages (3.sub.1-m or 4.sub.1-n). The high frequency stages (3.sub.1-m) are driven by equiphased control signals (s.sub.1-m); the high frequency stages (4.sub.1-n) are driven by control signals (t.sub.1-n) of different phase .PHI..sub.1-n. The high frequency stages (3.sub.1-m or 4.sub.1-n) can be selected in an arbitrary manner by the control signals (s.sub.1-m or t.sub.1-n). The summator adds the high frequency output signals (x.sub.1-m or y.sub.1-n) of the high frequency stages (3.sub.1-m or 4.sub.1-n). The output signal can be conveyed, for example, to a low pass and a subsequent load. The phases (.PHI..sub.1-n) of the output signals (y.sub.1-n) of the high frequency stages (4.sub.1-n) correspond to those of the control signals (t.sub.1-m). So many high frequency stages (3.sub.
