Abstract

本发明提供一种用于移动装置中的可展开天线。所述天线可折叠到收藏位置中，在所述收藏位置中，所述天线与外壳共面。所述天线也可打开，优选打开到一斜角，且用于接收来自至少6英寸远的无线功率。

Description

用于无线功率的可展开天线
背景技术
共同转让给本申请案的先前申请案已描述了通过使用(例如)磁场将功率以无线方式感应到接收器中来以无线方式将功率从发射器发送到接收器。
发射和接收天线及其设计在这种系统中变得很重要。
发明内容
本申请案描述一种用于无线功率的可展开天线。
附图说明
现在将参考附图详细描述这些和其它方面，其中：
图1展示蜂窝式电话中所使用的系统；
图2展示膝上型计算机中所使用的系统；
图3展示与PDA一起使用的系统；以及
图4展示打开到一斜角的翻板。
具体实施方式
在我方的在2007年7月9日申请且标题为“使用耦合天线的无线能量传送(WirelessEnergy Transfer Using Coupled Antennas)”的第11/775,168号专利申请案中详细描述了无线功率的概念，所述专利申请案的标的物明确地以引用的方式并入本文中。大体上，这描述了一种能够在通常大于6到12英寸且更通常在3英寸与6英尺之间的距离内发射功率的无线功率发射器和接收器。
然而，发明人已发现使无线功率接收天线过于靠近传导平面可能会减少接收到的功率。可能需要在具有传导要求的各种物品(例如POA、膝上型计算机和手机)中使用这种类型的功率接收天线。然而，这些装置中的每一者可具有本身形成传导平面的显示或印刷电路板。手机可能问题更多，因为手机可能使用接地平面作为其天线的一部分。
本发明的一方面是使用可展开天线，其维持一些或所有谐振器天线远离装置超过波长的1/10。一方面描述可展开天线的使用。
根据一个方面，无线功率接收天线嵌入在壳体的盖板中。在一个位置中，所述天线被收藏，所以所述天线被固定地按压抵靠着外壳且不占用额外空间。然而，可将天线打开到其接收位置。图1说明蜂窝式电话中的装置。蜂窝式电话100包含铰接的壳体部分。当闭合时，所述铰接的壳体部分覆盖键盘的某一或所有部分，或可折叠到背部部分上，以覆盖背部部分的一部分。然而，对于这些铰接“翻盖电话”来说常规的做法是覆盖键盘的某一或所有部分，以防止(例如)无意的拨号。在所述实施例中，铰接部分105包含我方的共同待决申请案中所描述的类型的接收天线110，其可包含感应式环形天线和电容器。铰接部分还可包含麦克风部分115，其优选朝铰接部分的边缘定位，以维持远离接收天线。
图2说明膝上型计算机200中所使用的实施例。在此膝上型计算机中，所述计算机包含展示为205的第三叶片，其包含嵌入其中的环形天线210。第三叶片通常可定位于膝上型计算机下面，且可从下面折叠到伸出位置以接收功率。
图3说明PDA中的装置，其中PDA 300的壳体可折叠出来以与其中的天线305形成翻盖件。所述实施例的每一者中的每一装置包含天线与位于移动装置内的接收电路之间的柔性带状电缆或其它柔性电子连接件。
在操作中，每当用户在充电区内时，用户可将天线从膝上型计算机405展开，如图4中所示。当打开时，在图4中展示为400的翻板与所有五个膝上型计算机的主外壳形成斜角，其为除0度或90度之外的角度。使用此斜角可防止原本可能(例如)由于正交感应干扰而发生的某些类型的干扰。这使得能够在处于所述区中时充电。无线功率天线因此可集成到原始装备中。这使得天线能够具有合适的谐振频率，其在集成到原始装备中时完全合适。谐振频率可在装置正被制造的时间期间考虑装置中的所有元件的所有阻抗。
尽管上文仅详细描述了几个实施例，但其它实施例也是可能的，且发明人希望这些实施例包含在本说明书内。本说明书描述了用以实现可以另一方式实现的较一般目标的具体实例。本发明既定为示范性的，且权利要求书既定涵盖所属领域的技术人员可能能够预测到的任何修改或替代方案。举例来说，这可并入到使用功率输入的其它电子装置或其它装置中。举例来说，另一方面可使得来自汽车的折页天线能够对与之相关联的电子电池进行充电。
而且，发明人希望仅使用词“用于......的装置”的那些权利要求既定根据35 USC112第六段加以解释。此外，不希望将来自说明书的任何限制加到任何权利要求中，除非那些限制明确地包含在所述权利要求中。本文所描述的计算机可为任何种类的计算机，通用或某种专用计算机(例如工作站)均可。
所述计算机可为运行视窗XP(Windows XP)或哩纳克斯(Linux)的基于英特尔(例如，奔腾或酷睿2)或AMD的计算机，或可为梅肯套希(Macintosh)计算机。所述计算机还可为手持式计算机，例如POA、手机或膝上型计算机。
程序可以C或Python或Java、Brew或任何其它编程语言编写。所述程序可驻存在存储媒体(例如，磁性或光学)上，
例如，计算机硬盘驱动器、可装卸盘或媒体，例如存储棒或SD媒体、基于有线或无线网络或基于蓝牙的网络附加存储装置(NAS)或其它可装卸媒体。程序还可经由网络(例如)通过服务器或其它机器向本地机器发送信号而运行，向本地机器发送信号允许本地机器执行本文所描述的操作。在本文中提及具体数值的情况下，应考虑到所述值可增加或减小20％，同时仍保持在本申请案的教示内，除非具体提及某一不同范围。在使用指定逻辑意义的情况下，还既定包含相反的逻辑意义。
