Description

用于实施无线电源的方法及设备
技术领域
本发明涉及以无线方式为装置供电。更特定来说，本发明涉及以无线方式为具有电荷存储组件的外罩的装置供电，其中无线电源装配到所述外罩中。
背景技术
随着处理器能力扩展及电力需求减小，完全不依赖电线或电力软线而操作的装置正在不断发展。这些“无系留”装置包括从蜂窝电话及无线键盘到建筑物传感器及有源射频识别(RFID)标签。
这些无系留装置的工程师及设计师仍然必须将便携式电源(主要使用电池)的限制作为关键设计参数来处理。虽然处理器及便携式装置的性能由摩耳定律(Moore’slaw)驱动而每18-24个月加倍，但容量方面的电池技术仅每年增长很少的6％。即使利用电力自觉设计及最新的电池技术，许多装置仍不能针对需要大量无系留装置的应用(例如，后勤保障及建筑物设备自动化)来满足寿命成本及维护要求。如今需要双向通信的装置需要每3到18个月进行定期维护以对装置的电源(通常为电池)进行更换或再充电。仅广播其状态而不接收任何信号的单向装置(例如，自动化实用电表读数器)的电池寿命较好，通常10年内需要进行更换。对于所述两种装置类型来说，定期电源维护较昂贵，且对于装置希望监视及/或控制的整个系统具有破坏性。非定期维护行为更为昂贵及具有破坏性。从宏观上来说，与内部电池相关联的相对较高的成本还减少了可部署的装置的实际或经济上可行的数目。
对无系留装置的电力问题的理想解决方案是可从外部环境收集并产生的充足能量的装置或系统。此能量可从许多不同能源中产生，例如太阳光、振动、热量或电磁辐射。然后所产生的能量可直接地为无系留装置供电或扩充电源。然而，由于外部环境中的低能量，此理想解决方案实施起来并不总是可行的。因此，地点上的限制可需要使用专用电源。本发明考虑到了这些因素并提供一种用于理想情况且还用于更多的限制性环境的解决方案。

在本发明的操作中，无线电源16的设计已详细描述于名称为“用于无线电源的方法及设备(Method and Apparatus for a Wireless Power Supply)”的美国专利第7,027,311号、名称为“使用RF能量收获的供电装置(Powering Devices using RF EnergyHarvesting)”的美国临时申请案第11/447,412号及名称为“用于各种负载的高效整流的方法及设备(Method and Apparatus for High Efficiency Rectification for VariousLoads)”的美国临时申请案第60/729,792号中，其所有内容以引用方式并入本文中。所引用的专利详细论述了如何设计及构造无线电源或RF能量收获器以用于各种应用，例如为无线的(例如但不限于蜂窝电话)或有线的用于通信或供电的或此两者，例如但不限于工业传感器。然而，描述如何用新的及现有的装置集成或实施无线电源(WPS)或RF能量收获器已变得有利且成为本发明的中心。应注意，术语无线电源或WPS可用于描述用于RF能量收获的电路或与RF收获天线18结合使用的用于RF能量收获的电路。所述WPS可用于收获RF能量并将RF能量转换为可用形式，例如但不限于直流(DC)电力。
本发明可使用脉冲RF或其它能量传输器，例如，如名称同为“脉冲传输方法(Pulsing Transmission Method)”的两个美国临时申请案第60/656,165号及第11/356,892号中所描述，其以引用方式并入本文中。
对于含有电荷存储组件50的装置(例如但不限于电池20)来说，以各种方式实施或集成无线电源16是可能的。WPS可经设计以装配到用于容纳电池20、电池或电荷存储组件50的外罩14、隔室或空间中。此可包含任何电池20或电荷存储组件50大小及/或形状，其中包含但不限于ANSI C18.1M，1-2001部分中所描述的电池，其以引用方式并入本文中。WPS可在直接供电应用中完全地取代电池20、电池组30或电荷存储组件50，或者可在电池20及电荷存储组件50的再充电中取代一个或一个以上电池20或电荷存储组件50。举例来说，曾用WPS改装无线温度及湿度传感器以由于WPS对电池20进行再充电及天线18捕获并转换RF能量而获得较长的电池20寿命。无线传感器含有使用四个AAA碱性电池构造而成的3伏电池20组30，其示意图及图式分别显示于图1a及图1b中。通过用WPS或能量收获器取代所述电池中的两者来将WPS改装到无线传感器中。WPS印刷电路板62(PCB)具有0.83×1.84英寸的尺寸且经设计以装配到由两个拆除的电池留下的空间中。使用end-launchSMA连接器36将RF收获天线18连接到WPS PCB，所述end-launchSMA连接器激励无线传感器外罩14以允许RF收获天线18位于无线传感器外部。使用两个AAA电池的WPS的示意图可参见图2a。图2b图解说明如何配置WPS以取代所述AAA电池中的两者并在使用两个AAA电池时保持与无线传感器的原始电池20组30相同的大小及/或尺寸。应注意，如果发现对所述应用是有利的，则WPS可与电池20或电池串联或并联放置。
在与先前描述的类似的实施例(取代所述电池中的一者或所有)中，可以与任何电池类型或电池组合(例如但不限于WPSANSI C18.1M，1-2001部分中所描述的电池)相似或采取其大小及形状的一种方式来制造WPS。举例来说，WPS可设计有允许将其装配到标准AA电池20的外壳或壳中的大小及形状，如图3所示。在此情况下，可无需具有电池20化学物，且具有电池20的形状的WPS可含有WPS电路、PCB、电荷存储组件50及/或RF收获天线18。如果发现是有利的，则天线18还可位于WPS外部。电荷存储组件50包含但不限于：电容器、超级电容器或任何其它能够存储电荷的组件。
如先前所描述，WPS可取代装置12中的一个或所有电池，不论是不是具有电池20的形式。如果取代了所有电池，则WPS向装置12提供直接电力，然而，如果仅取代装置12中的一个或某些电池，则WPS可提供用于对剩余电池再充电或扩充剩余电池的电流，因此排除了拆除电池来取代或再充电或将装置12插入到电网以对电池再充电的需要。应注意，可使用可再充电及不可再充电电池来实行此实施例。对于不可再充电电池来说，必须添加保护电路以确保不向不可再充电电池提供任何充电电流，这意味着WPS所提供的任何能量都被用于为装置12直接供电。举例来说，考虑一种由两个不可再充电AA电池供电的无线传感器。经制造以类似于AA电池的两个WPS可取代两个不可再充电电池。然而，如果仅需要一个经制造以类似于AA电池的WPS，则另一不可再充电电池可由可再充电AA电池取代或加以保护或配置(串联)以确保所述不可再充电电池不会由WPS充电。本发明所使用的可再充电电池化学物可以是但不限于：镍金属氢化物(NiMH)、镍镉(NiCd)、锂离子、锂聚合物、可再充电碱、铅酸、锂薄膜或任何其它类型的可再充电电池化学物25。
RF电力接收天线18可位于电池20或具有电池20的大小的组件的内部(如图3所示)或外部(如图4所示)。
极其类似于先前所描述及图3中所示的WPS的另一实施例为将WPS包含在标准大小或自定大小的可再充电电池20的封装中且同进保持电池20的功能。此可再充电电池化学物25或电池20的能量部分28可以是但不限于：NiMH、NiCd、锂离子、锂聚合物、可再充电碱、铅酸、锂薄膜或任何其它类型的可再充电电池化学物25。这可需要置换电池20中的某些化学物以为WPS、PCB及/或可能地为RF收获天线18留出空间。此实施例可参见图5。电池20可正常地发挥作用，但可由于移除了某些化学物而具有略小的电荷容量。在此情况下，WPS可对具有WPS的外壳中存在的电池20化学物充电或扩充，而外壳中的电池20化学物可为用WPS改进的装置12提供操作电力。对于具有不处于RF电力场中的可能性的装置(例如但不限于：蜂窝电话、PDA或任何其它由移动电池20供电的装置)来说，这是一个比图3中所显示的更具吸引力的实施例。在先前的情况下，WPS类似于电池20但不具备电池20的功能，如果WPS没有正从RF电力传输器或RF电力网络接收电力，则仅使用WPS来供电的装置12不会发挥作用。但是，对于图5中所示的情况来说，且在仅取代装置12的一个或某些电池的先前情况下，WPS-电池20组合仍具有在不处于RF电力场时向装置12提供操作电力的能力。举例来说，可需要用取代电池20的WPS来改进蜂窝电话。大多数蜂窝电话仅具有一个可修改的电池20组30。在此实例中，图3中所显示的实施例可能不是最佳选择，因为蜂窝电话仅在处于RF电力场中时或当在RF电力场中的时间周期时电荷存储组件50(例如电容器)内存储有电荷时才运行。因为可使蜂窝电话四处移动，所以即使在不是RF电力场的地方，改进此蜂窝电话的最佳选择也是将可再充电电池化学物25包含在内，其中当蜂窝电话不在RF电力场中时由WPS向蜂窝电话提供可操作电力。
在先前实施例的情况下，RF电力接收天线18可位于含有电池20化学物的电池20或具有电池20大小的组件的内部(如图5中所示)或外部(如图6中所示)。
对于内部RF收获天线18来说，只要外壳由在所关注频率下对RF场具有极低或不具有衰减的材料(例如但不限于塑料)构成，天线18即可形成于电池外壳26内部。对于非衰减外壳来说，天线18可形成为所述外壳的一部分。举例来说，所述外壳可由塑料材料制成，所述塑料内设置有金属偶极子。对于由衰减的材料(例如金属)构成的外壳来说，使电池20的金属外壳发生谐振以形成RF收获天线18也是可能的。不论电池20的外壳是否电连接到电池20的一个端子，均可使外壳发生谐振。在外壳浮动或没有电连接到电池20的端子的情况下，WPS可通过阻抗匹配网络连接到金属的或其它合适的天线18材料的外壳以将金属外壳阻抗匹配到WPS。另外，WPS及/或阻抗匹配电路与外壳之间的接触点可用于协助阻抗匹配且还可帮助调整及/或改进电池外壳22RF收获天线18的辐射特性。此一实例可参见图7，其中天线18形成为中空圆柱体且像外壳一样环绕WPS及/或电池化学物25。对于所述实施例中的任一者来说，可必要地将电池外壳22划分为两个或两个以上电绝缘或电隔离部分以使电池外壳22发生谐振。举例来说，电池外壳22可通过在偶极子的两部分之间放置绝缘材料或电介质而形成为偶极子天线18(天线18形成为中空圆柱体)，如图8所示。图8中所示的此实例由于偶极子天线18的平衡性质而具有两个天线18馈电线。馈电点的数目将取决于WPS所使用的天线18的类型。
应注意，本文实施例中的任一者均可形成为WPS或形成为包含电池化学物25的WPS，不论是否显示于说明性图式中。
另外，WPS可含有或具有外部阻抗匹配以保证从天线18到WPS的最大电力传输。WPS可经设计以匹配天线18，或反之亦然，而不需要阻抗匹配。因此，所形成的WPS及天线18系统可具有或可不具有标准阻抗，例如50欧姆。
对于电池外壳22电连接到一个电池20端子的情况来说，可需要将隔离添加到电连接的电池20端子以保证RF噪声没有注入到从WPS及/或电池20接收电力的装置12中且保证装置12不会载入电池外壳22RF收获天线18且致使天线18的特性(例如阻抗)发生变化。此隔离可仅仅是低通滤波器(LPF)，其可允许来自电池20的DC能量流到装置12且同时阻挡RF能量。此一实例可参见图9。应注意，LPF可视具体应用而位于电池20的内部或外部。
对于外部RF收获天线18来说，天线18可形成于电池20上或远离电池20。RF收获天线18可形成于如图10所显示的非衰减外壳外部，或可通过在金属或衰减外壳与天线18之间放置电介质而形成于金属或衰减外壳上，如图11所示。金属外壳可充当反射体或接地平面以帮助增大天线18的增益。对于金属外壳来说，其还可能包含凹处，天线18可形成于所述凹处中且同时保证齐平的表面，如图12中可见。所述凹处可限制在外壳的一侧或可包含整个电池20圆柱体。另外，金属外壳可具有电隔离或电绝缘区域，天线18可形成于所述区域中。在某些应用中，使用电池20标签来形成天线18是可能的，所述标签可部分地或全部为金属的，例如金属箔。此一实例可参见图13。
在某些应用中，使天线18远离电池20或电荷存储组件50而定位是有利的。在这些情况下，天线18可连接到位于电池20上的专用端子。举例来说，电池20的本体可含有两个金属垫48或环绕电池20外部的环，如图14所示，其中天线18或传输线60可使用弹簧加载触点来连接。还可能包含连接器36、插孔、插头或适配器，这取决于电池20及电池外罩14的大小及形状，如图15所示。
在某些应用中，使用电池20的外壳作为天线18的一部分可是有利的。举例来说，可将金属(或其它导电材料)电池外壳22用作贴片天线18的接地平面。所述贴片可形成于金属(或其它导电材料)电池外壳22上方且由非导电材料隔开。WPS可位于电池20内部或外部且可用同轴电缆、微带或任何其它馈电技术来为贴片天线18馈电。图16中可见使用金属电池外壳22来作为接地平面的同轴馈电贴片天线18的实例。应注意，电池外壳22可以是浮动的或可连接到一个电池20端子。
应注意，可以任何类型及数目的天线来实施本文所描述的天线18配置。举例来说，WPS可连接到一个以上RF收获天线18，其中每一天线18均可以是但不限于：偶极子、单极子、贴片、微带或任何其它天线18类型或配置。在某些应用中，也可有利地具有可连接到一个或一个以上天线的多个WPS。
在先前的实施例中，WPS集成到电池20或具有电池20大小的外罩14中，而天线在内部或外部。在某些应用中，可有利地使WPS位于电池20或具有电池20大小的外罩14外部，而天线可位于外罩14内部或外部。举例来说，WPS可形成于电池20的外壳上，而天线如前文描述可在外部连接到电池外壳22或形成为电池外壳22的一部分。图17中可见使用电池外壳22作为天线18的外部WPS的实例。
在某些应用中，可使用多个电池外壳22来形成WPS的天线18。举例来说，可使用两个具有浮动外壳的AA电池来形成偶极子天线18，如图18所示。根据将被收获的RF电力的一个频率或多个频率，可必要地包含阻抗匹配网络以将偶极子天线18匹配到WPS。
在先前实施例中，使用多个电池外壳22来形成RF收获天线18。由于到电池20的电力连接可导致对天线18的辐射特性不合需要的影响，使用电池外壳22来形成天线18并不总是有利的。因此，RF电力收获天线18可环绕电池20或多个电池形成以启用不会影响天线18的辐射特性的有线连接。举例来说，可使用两个由导电材料(例如但不限于金属)制成的中空圆柱体(每一中空圆柱体均含有AA电池20)来形成偶极子天线18。WPS可安装在两个中空圆柱体之间，两者均具有电连接。另外，来自WPS的电线可从圆柱体内部穿到电池两端以作出用于电池20再充电的电连接。因为位于圆柱体内部，所以所述电线不会对天线18的辐射特性产生影响，且由于表层的影响，RF电流均存在于圆柱体表面上。另外，可在天线18的每一端处添加隔离以将WPS电池20再充电单元的电力端子与RF电力收获天线18结构隔离。图19中可见WPS电池20再充电单元的实例。
在某些应用中，改进或重新设计含有WPS及/或RF收获天线18的产品可能不是有利的。因此，WPS及RF收获天线18可经设计以位于装置12外部，且WPS的输出可通过连接器36、插口、插头或适配器连接到装置12以使由WPS捕获的能量被传送到装置12来用于直接的供电应用，或传送到可再充电电池20或电荷存储组件50以用于电池20再充电或扩充应用。WPS可以连接到现有的端口、连接器36、插口、插头或适配器的方式来设计，其经设计以用于再充电设备52的连接，所述再充电设备从除RF电力收获以外的装置获得其电力，例如但不限于机动车中的AC电网或DC电力。举例来说，可用使用电池20再充电插座的WPS及RF收获天线18对蜂窝电话再充电，所述电池再充电插座可构建于所述电话中以通过到墙壁或汽车电源插座的有线连接来进行电池20再充电。WPS可用集成天线18装配到PCB上，如图20所示。还可能将WPS及RF收获天线18中的任一者包含在装置12内部，而另一者位于装置12外部并通过连接器36、插口、插头或适配器连接到装置12。举例来说，WPS可足够小以装配到蜂窝电话中。然而，当位于所述蜂窝电话外部时，天线18可能会过大或可具有更好的RF电力收获特性。因此，WPS可放置在蜂窝电话内部，而RF电力收获天线18位于蜂窝电话外部。外部RF电力收获天线18可使用现有的或专用连接器36来连接。
在某些应用中，可有利地将WPS及RF电力收获天线18构建到装置的现有附件或外部组件(例如但不限于：保护盖、保护壳、腰带扣、皮套、固定器、面板、入坞站、项链架、臂章架、头戴耳机、装运箱或任何其它装置附件)中或其上。举例来说，经常使用皮制外壳来保护蜂窝电话以避免对电话的损害及擦伤。可将WPS及RF收获天线18设计到蜂窝电话盖54中，其中使所述盖插入到电池20再充电插座中，所述电池再充电插座构建于所述电话中并连接到WPS的输出以对蜂窝电话电池20再充电。蜂窝电话盖54还可具有接纳来自标准再充电设备52的连接或穿过所述连接的能力，所述标准再充电设备具有到墙壁或汽车电源插座的有线连接。举另一实例来说，可以与蜂窝电话类似的方式对iPOD或其它音乐装置再充电。然而，在iPOD的情况下，WPS及RF收获天线18可远离装置12定位并附装到头戴耳机56的软线。WPS的输出可通过软线被供应到iPOD，所述软线可通过连接器36、插口、插头或适配器附装到iPOD再充电插座，如图21所示。还可能将WPS及天线18集成到现有的头戴耳机56软线中以消除所需要的第二电线及连接器36。
在某些应用中，将WPS集成到天线18或天线18结构中可是有益的。因此，天线18的输出不会是RF电力，而是可由装置12使用的电力形式，例如但不限于DC电力。将WPS集成到天线18中可消除由连接器36及若干段传输线60导致的损耗源。因此，所形成的WPS及RF收获天线18可具有较高的效率。举例来说，同轴偶极子为经设计以直接连接到同轴电缆的不平衡天线18。所述偶极子的两个轴向元件在偶极子中央汇合，且两个导体通过形成为中空圆柱体的较低的轴向元件退出到偶极子末端。典型的同轴偶极子可参见图22a。如图22b显示，WPS可集成到天线18及DC电力中，所述DC电力可由连接到DC连接器36、插口、插头或适配器的两个导体传递到偶极子底部。
在某些应用中，还可有利地将WPS实施为同轴(或其它传输线60)线内设备58。天线18的输出可连接到WPS且WPS通过连接器36、插口、插头或适配器将DC电力传递到连接到WPS的装置12。举例来说，具有SMA连接器36的同轴偶极子可连接到位于WPS上的相反极性的SMA连接器36。WPS可接纳RF收获天线18所提供的RF电力，且WPS将DC电力输出到通过连接器36、插口、插头或适配器连接的装置12，以直接为装置12供电或对装置12电荷存储组件50再充电。线内同轴WPS的实例可参见图23。
WPS可以若干方式形成。在新的设计中，WPS可集成到现有的或新设计的PCB上，其中集成或外部天线18用于收获RF能量。WPS可呈离散组件42及/或集成电路的形式。在集成电路的情况下，可必要地使用一个或一个以上外部组件以使由集成电路固有的寄生元件(例如但不限于：导体、半导体及金属半导体接合的有限电阻、低质量因素电感器、衬底40的电容、其它组件的电容及其它寄生元件)导致的WPS转换效率的损耗最小化。
WPS还可实施为含有离散组件42及集成电路44的PCB(或其它衬底40)。所述PCB可含有用于连接到另一PCB或衬底40的通孔销或表面安装垫48。举例来说，名称为“用于对各种负载的高效整流的方法及设备(Method and Apparatus for HighEfficiency Rectification for Various Loads)”的美国临时申请案第60/729,792号中显示的WPS实施为具有四个表面安装垫的模块。RF输入垫连接到天线18、输出垫连接到装置12以用于直接供电且连接到电池20或电荷存储组件50以用于再充电应用，且其它两个垫连接到接地。所述模块经设计以焊接到另一PCB上以保证适当的布局且便于由用户使用。图24显示WPS模块的尺寸。
当发现有利时，WPS可实施为电池20组30或实施于所述电池20组30中。举例来说，WPS及RF电力收获天线18可形成于电池20或多个电池的外部封装内或其上，而保持在电池外壳26外部。举一特定的实例，通常将蜂窝电话电池装入塑料外壳中以提供保护、给予支撑并呈现美观的大小及形状。电池及(可能的)电池再充电或保护电路形成于所述塑料外壳内。WPS及RF电力收获天线18还可形成于塑料外壳内以使其成为电池组30的一部分。在某些应用中，可有益地将RF电力收获天线18形成为外部组件或将RF电力收获天线18形成于用于盛装电池20的塑料(或其它材料)外壳外面上。装有电池20或多个电池的WPS的实例显示于图25中。
本发明不应与通过感应耦合的电力传送混淆，所述电力传送要求装置12相对靠近电力传输源。作者克劳斯·芬克泽勒(Klaus Finkenzeller)所著的RFID手册将感应耦合区定义为传输器与接收器之间小于0.16×λ的距离，其中λ为RF波的波长。本发明可实施于近场(有时称作感应)区及远场区中。远场区是大于0.16×λ的距离。
在本发明的任何实施例中，所传输的RF电力均可限定为仅包含电力，即，信号中不存在数据。如果所述应用需要数据，则所述数据优选地在单独的频带中传输且/或具有单独的接收器。
虽然在前述实施例中出于图解说明的目的对本发明进行了详细描述，但是应了解，所述细节仅用于该目的，且除可在所附权利要求书中加以描述外，所属技术领域的技术人员可在不背离本发明的精神及范围的情况下对其进行变动。
