Description
[0001]この出願は、米国仮出願61/730492(出願日:2012年11月27日、名称:“手首着用デバイスを無電で充電するための装置”)および米国仮出願61/747185(出願日:2012年12月28日、名称“無線充電システム”)の優先権を請求するとともに、出願日の利益を請求するものであり、いずれも参照によってこの文書に組み込まれている。
[0002]多くのポータブル無線デバイスは再充電可能な電源に依存している。そのようなポータブルデバイスのフォームファクタ(form factor)は大きく異なっているが、特に人気を獲得しているフォームファクタは、手首着用型デバイスあるいは首着用デバイスに組み込まれたポータブルデバイスである。小さな、手首着用デバイスの一例は、無線ヘッドセットあるいはイヤピースと対となって、ポータブルセルラ電話として機能するデバイスである。他のデバイスおよびデバイス機能性は手首着用デバイス内に組み込み可能である。
[0043]実施形態において、受信アンテナ160が組み込まれる装置は、ループ形状の構成あるいは位置、およびC形状の構成または位置のいずれかをもつことができ、手首バンドの周りに配置し、その後、手首バンドが手首の周りに固定されたときに、ループ形状の位置に閉じることを可能にするために、“C”形状の位置に対して開放可能な手首バンド内に配置されることを可能にするために、ループ形状の構成あるいは位置、とC形状の構成または位置の間で移動されるように構成される。さらに受信アンテナ160は概して、数多くの異なるアプリケーションに適合するような形状にすることができる。受信アンテナ160の制限されない例のループ形状の構成は、円形、三角形、六角形、五角形、および他のループ形状を含む。もちろん、受信アンテナ160は他の適当な形状を有する。
