Problems solved by technology

While suitable for applications requiring relatively low power (on the order of mW), this same process is not suitable for applications requiring more power (at least on the order of a few watts to several hundred watts) or where the power source and power sink are further spaced from each other (e.g. , inches to feet) for those applications

Abstract

Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.

Description

technical field [0001] The described embodiments relate generally to wireless charging, and more particularly to devices, systems, and methods related to distributing power to receiver devices that may be located in a wireless power system. Background technique [0002] Historically, transmitting power wirelessly has only been successful for limited applications. In particular, only those applications where the wireless power source and the wireless power receiver are in close proximity to each other have been successful. In this arrangement, the wireless power source and wireless receiver are typically inductively coupled through a magnetic field capable of coupling both the power source and receiver. While suitable for applications requiring relatively low power (on the order of mW), this same process is not suitable for applications requiring more power (at least on the order of a few watts to several hundred watts) or where the power source and power sink are further sp...
