依据35U.S.C.§119(e)主张优先权
本申请案依据35U.S.C.§119(e)主张以下申请案的优先权:
2009年11月17日申请的标题为“无线电力(WIRELESSPOWER)”的第61/262,119号美国临时专利申请案,所述专利申请案的揭示内容特此以全文引用的方式并入本文中。
技术领域
本发明大体上涉及无线电力,且更具体地说,涉及电力管理、无线充电器的定位以及自动化无线充电。
背景技术
通常,每一电池供电的装置需要其自身的充电器及电源,所述电源通常为交流(AC)电源插座。在许多装置需要充电时,这变得难以使用。
正开发在发射器与待充电的装置之间使用空中电力发射的做法。这些做法大体上属于两种类别。一种类别是基于发射天线与待充电的装置上的接收天线之间的平面波辐射(也称为远场辐射)的耦合,所述待充电的装置收集所辐射的电力且对其整流以用于对电池充电。天线大体上具有谐振长度以便改进耦合效率。此做法的缺点为电力耦合随着天线之间的距离增加而迅速衰退。因此,超过合理距离(例如,>1到2米)的充电变得困难。另外,因为系统辐射平面波,所以如果未经由滤波来进行适当控制,那么无意的辐射可干扰其它系统。
其它做法是基于嵌入于(例如)“充电”垫或表面中的发射天线与嵌入于待充电的主机装置中的接收天线加整流电路之间的电感耦合。此做法具有以下缺点:发射天线与接收天线之间的间距必须非常接近(例如,几毫米)。虽然此做法确实具有对同一区域中的多个装置同时充电的能力,但此区域通常较小,因此用户必须将所述装置定位到特定区域。
需要用于管理与电子装置相关联的电力、定位无线电力充电器及自动化无线充电的系统、装置及方法。

具体实施方式
下文中结合附图所阐述的详细描述意在作为对本发明的示范性实施例的描述,且无意表示可实践本发明的仅有实施例。遍及此描述所使用的术语“示范性”表示“充当实例、例子或说明”,且未必应被解释为比其它示范性实施例优选或有利。所述详细描述包括特定细节以便实现提供对本发明的示范性实施例的透彻理解的目的。所属领域的技术人员将明白,可在无这些特定细节的情况下实践本发明的示范性实施例。在一些例子中,以框图形式展示众所周知的结构及装置,以便避免混淆本文中所呈现的示范性实施例的新颖性。
词“无线电力”在本文中用以表示在不使用物理电磁导体的情况下在从发射器到接收器之间发射的与电场、磁场、电磁场或其它相关联的任何形式的能量。应注意,本发明可适用于任何合适的无线电力情况,例如近场、远场、谐振及电感耦合。
图1说明根据本发明的各种示范性实施例的无线发射或充电系统100。将输入电力102提供给发射器104以供产生用于提供能量传送的辐射场106。接收器108耦合到辐射场106,且产生输出电力110以供耦合到输出电力110的装置(未图示)储存或消耗。发射器104与接收器108两者分开达距离112。在一个示范性实施例中,根据相互谐振关系来配置发射器104及接收器108,且在接收器108的谐振频率与发射器104的谐振频率非常接近时,当接收器108位于辐射场106的“近场”中时,发射器104与接收器108之间的发射损失最小。
发射器104进一步包括用于提供用于能量发射的装置的发射天线114,且接收器108进一步包括用于提供用于能量接收的装置的接收天线118。根据应用及待与之相关联的装置来设计发射天线及接收天线的大小。如所陈述,通过将发射天线的近场中的大部分能量耦合到接收天线而非以电磁波形式将多数能量传播到远场来发生高效能量传送。当在此近场中时,可在发射天线114与接收天线118之间形成耦合模式。可发生此近场耦合的在天线114及118周围的区域在本文中称作耦合模式区。
图2展示无线电力传送系统的简化示意图。发射器104包括振荡器122、功率放大器124,及滤波器及匹配电路126。所述振荡器经配置以在所要频率下产生信号,所述所要频率可响应于调整信号123来加以调整。可由功率放大器124以响应于控制信号125的放大量来放大振荡器信号。可包括滤波器及匹配电路126以滤出谐波或其它不想要的频率,且使发射器104的阻抗与发射天线114匹配。
接收器108可包括匹配电路132以及整流器及切换电路134,以产生直流(DC)电力输出以对电池136(如图2中所展示)充电或对耦合到接收器的装置(未图示)供电。可包括匹配电路132以使接收器108的阻抗与接收天线118匹配。接收器108与发射器104可在单独通信信道119(例如,蓝牙、紫蜂(zigbee)、蜂窝式等)上通信。
如图3中所说明,示范性实施例中所使用的天线可配置为“环形”天线150,其在本文中还可称作“磁性”天线。环形天线可经配置以包括空气芯或物理芯(例如,铁氧体芯)。空气芯环形天线可较能容忍放置于所述芯附近的外来物理装置。此外,空气芯环形天线允许其它组件放置于芯区域内。另外,空气芯环可较易于使得能够将接收天线118(图2)放置于发射天线114(图2)的平面内,在所述平面内,发射天线114(图2)的耦合模式区可较强大。
如所陈述,在发射器104与接收器108之间的匹配或近似匹配的谐振期间,发生发射器104与接收器108之间的高效能量传送。然而,甚至在发射器104与接收器108之间的谐振不匹配时,仍可以较低效率传送能量。通过将来自发射天线的近场的能量耦合到驻留在建立此近场的邻域中的接收天线而非将能量从发射天线传播到自由空间中来发生能量传送。
环形天线或磁性天线的谐振频率是基于电感及电容。环形天线中的电感大体上仅为由环所产生的电感,而电容大体上与环形天线的电感相加以在所要谐振频率下产生谐振结构。作为非限制性实例,可将电容器152及电容器154添加到所述天线以创建产生谐振信号156的谐振电路。因此,对于较大直径的环形天线来说,诱发谐振所需的电容的大小随着环的直径或电感增加而减小。此外,随着环形天线或磁性天线的直径增加,近场的高效能量传送区域增大。当然,其它谐振电路为可能的。作为另一非限制性实例,电容器可并联放置于环形天线的两个端子之间。另外,所属领域的技术人员将认识到,对于发射天线,谐振信号156可为到环形天线150的输入。
图4为根据本发明的示范性实施例的发射器200的简化框图。发射器200包括发射电路202及发射天线204。一般来说,发射电路202通过提供致使在发射天线204周围产生近场能量的振荡信号来将射频(RF)电力提供给发射天线204。仅举例来说,发射器200可在13.56MHz的ISM频带下操作。
示范性发射电路202包括固定阻抗匹配电路206,其用于使发射电路202的阻抗(例如,50欧姆)与发射天线204匹配;及低通滤波器(LPF)208,其经配置以将谐波发射减少到防止耦合到接收器108(图1)的装置的自干扰的电平。其它示范性实施例可包括不同滤波器拓扑(包括(但不限于)使特定频率衰减同时使其它频率通过的陷波滤波器),且可包括自适应阻抗匹配,所述自适应阻抗匹配可基于可测量发射量度(例如,到天线的输出功率或由功率放大器汲取的DC电流)而变化。发射电路202进一步包括经配置以驱动如由振荡器212确定的RF信号的功率放大器210。发射电路可由离散装置或电路组成,或替代地可由集成组合件组成。来自发射天线204的示范性RF功率输出可为约2.5瓦。
发射电路202进一步包括控制器214,其用于在特定接收器的发射阶段(或工作循环)期间启用振荡器212、用于调整所述振荡器的频率,及用于调整用于实施通信协议(用于经由相邻装置所附接的接收器与相邻装交互)的输出功率电平。
发射电路202可进一步包括负载感测电路216,其用于检测在由发射天线204产生的近场附近的作用中接收器的存在或不存在。举例来说,负载感测电路216监视流动到功率放大器210的电流,其受在由发射天线204产生的近场附近的作用中接收器的存在或不存在影响。对功率放大器210上的负载的改变的检测是由控制器214监视,以用于确定是否启用振荡器212以发射能量以与作用中接收器通信。
发射天线204可实施为天线条带,其具有经选择以使电阻损失保持较低的厚度、宽度及金属类型。在常规实施方案中,发射天线204可大体上经配置以与较大结构(例如,桌子、垫、灯或其它不便携带的配置)相关联。因此,发射天线204大体上将不需要“匝”,以便具有实用尺寸。发射天线204的示范性实施方案可为“电学上较小”(即,波长的分数)且经调谐以通过使用电容器来界定谐振频率而在较低可用频率下谐振。在发射天线204的直径或边长(如果为正方形环)相对于接收天线来说可较大(例如,0.50米)的示范性应用中,发射天线204将未必需要较大数目的匝来获得合理电容。
发射器200可搜集并追踪关于可能与发射器200相关联的接收器装置的行踪及状态的信息。因此,发射器电路202可包括连接到控制器214(在本文中也称作处理器)的存在检测器280、封入式检测器290,或其组合。控制器214可响应于来自存在检测器280及封入式检测器290的存在信号而调整由放大器210递送的电力的量。发射器可经由若干电源(例如,用以转换存在于建筑物中的常规AC电力的AC到DC转换器(未图示)、用以将常规DC电源转换到适合于发射器200的电压的DC到DC转换器(未图示))接收电力,或可直接从常规DC电源(未图示)接收电力。
作为一非限制性实例,存在检测器280可为运动检测器,其用以感测插入到发射器的覆盖区域中的待充电装置的初始存在。在检测之后,可接通发射器,且可使用由装置接收的RF电力来以预定方式拨转Rx装置上的开关,这继而导致发射器的驱动点阻抗的改变。
作为另一非限制性实例,存在检测器280可为能够(例如)通过红外线检测、运动检测或其它合适方式检测人类的检测器。在一些示范性实施例中,可能存在限制发射天线可在特定频率下发射的功率的量的规则。在一些情况下,这些规则意在保护人类免受电磁辐射。然而,可能存在发射天线放置于人类未占据或人类很少占据的区域(例如,车库、厂区、店铺等)中的环境。如果这些环境无人类,那么可能可准许将发射天线的功率输出增加到高于正常功率限制规则。换句话说,控制器214可响应于人类存在而将发射天线204的功率输出调整到管制电平或以下,且当人类在距发射天线204的电磁场管制距离以外时,将发射天线204的功率输出调整到高于所述管制电平的电平。
作为一非限制性实例,封入式检测器290(在本文中还可称作封入式隔间检测器或封入式空间检测器)可为例如感测开关等装置,其用于确定封入件何时处于封闭或开放状态。当发射器处于呈封入状态的封入件中时,可增加发射器的功率电平。
在示范性实施例中,可使用发射器200藉以不会无限地保持开启的方法。在此情况下,发射器200可经编程以在用户确定的时间量之后切断。此特征防止发射器200(尤其是功率放大器210)在其外围的无线装置完全充电之后长时间运转。此事件可能归因于电路无法检测到从中继器或接收线圈发送的指示装置完全充电的信号。为了防止发射器200在另一装置被放置于其周边时自动地切断,可仅在检测到发射器200的周边缺乏运动的设定时段之后激活发射器200自动切断特征。用户可能能够确定停止使用(inactivity)时间间隔,且在需要时改变所述停止使用时间间隔。作为非限制性实例,所述时间间隔可比在假定特定类型的无线装置最初被完全放电的情况下对所述装置完全充电所需的时间间隔长。
图5为根据本发明的示范性实施例的接收器300的简化框图。接收器300包括接收电路302及接收天线304。接收器300进一步耦合到装置350以向其提供所接收的电力。应注意,将接收器300说明为在装置350外部,但可将接收器300集成到装置350中。一般来说,将能量无线传播到接收天线304,且接着经由接收电路302而耦合到装置350。
接收天线304经调谐以在与发射天线204(图4)相同的频率下或几乎相同的频率下谐振。接收天线304可与发射天线204类似地设定尺寸,或可基于相关联装置350的尺寸来不同地设定大小。举例来说,装置350可为具有比发射天线204的直径或长度小的直径或长度尺寸的便携式电子装置。在此实例中,接收天线304可实施为多匝天线以便减小调谐电容器(未图示)的电容值,且增加接收天线的阻抗。举例来说,可将接收天线304放置于装置350的实质周长周围,以便使天线直径最大化且减小接收天线的环匝(即,绕组)的数目及绕组间电容。
接收电路302提供与接收天线304的阻抗匹配。接收电路302包括电力转换电路306,用于将所接收的RF能源转换成供装置350使用的充电电力。电力转换电路306包括RF到DC转换器308,且还可包括DC到DC转换器310。RF到DC转换器308将接收天线304处所接收的RF能量信号整流成非交流电力,而DC到DC转换器310将经整流的RF能量信号转换成可与装置350兼容的能量电位(例如,电压)。预期有各种RF到DC转换器,包括部分及全整流器、调节器、桥接器、倍加器以及线性及切换转换器。
接收电路302可进一步包括切换电路312,其用于将接收天线304连接到电力转换电路306,或替代地用于断开电力转换电路306。将接收天线304从电力转换电路306断开不仅暂时中止对装置350充电,而且改变如发射器200(图2)所“见到”的“负载”。
如上文所揭示,发射器200包括负载感测电路216,其检测提供给发射器功率放大器210的偏压电流的波动。因此,发射器200具有用于确定接收器何时存在于发射器的近场中的机构。
当多个接收器300存在于发射器的近场中时,可能需要对一个或一个以上接收器的加载及卸载进行时间多路复用,以使其它接收器能够更高效地耦合到发射器。还可隐匿接收器以便消除到其它附近接收器的耦合或减少附近发射器上的负载。接收器的此“卸载”在本文中也称为“隐匿”。此外,如下文更完全地解释,由接收器300控制且由发射器200检测的卸载与加载之间的此切换提供从接收器300到发射器200的通信机制。另外,一协议可与所述切换相关联,所述协议使得能够将消息从接收器300发送到发射器200。举例来说,切换速度可为约100微秒。
在一示范性实施例中,发射器与接收器之间的通信指代装置感测及充电控制机制而非常规双向通信。换句话说,发射器使用所发射的信号的开/关键控,以调整能量在近场中是否可用。接收器将这些能量改变解译为来自发射器的消息。从接收器侧来说,接收器使用接收天线的调谐与解除调谐来调整正从近场接受的电力的量。发射器可检测来自近场的所使用的电力的此差异,且将这些改变解译为来自接收器的消息。
接收电路302可进一步包括用以识别所接收的能量波动的信令检测器及信标电路314,所述能量波动可对应于从发射器到接收器的信息信令。此外,信令及信标电路314还可用以检测减少的RF信号能量(即,信标信号)的发射,且将所述减少的RF信号能量整流成标称电力以用于唤醒接收电路302内的未供电或电力耗尽的电路,以便配置接收电路302以用于进行无线充电。
接收电路302进一步包括处理器316,其用于协调本文中所描述的接收器300的进程(包括对本文中所描述的切换电路312的控制)。还可在发生其它事件(包括检测到向装置350提供充电电力的外部有线充电源(例如,壁式/USB电源))后发生接收器300的隐匿。除控制接收器的隐匿之外,处理器316还可监视信标电路314以确定信标状态,且提取从发射器发送的消息。处理器316还可调整DC到DC转换器310以获得改进的性能。
图6展示用于执行发射器与接收器之间的消息接发的发射电路的一部分的简化示意图。在本发明的一些示范性实施例中,可在发射器与接收器之间启用用于通信的装置。在图6中,功率放大器210驱动发射天线204以产生辐射场。所述功率放大器由载波信号220来驱动,所述载波信号220在发射天线204的所要频率下振荡。使用发射调制信号224来控制功率放大器210的输出。
发射电路可通过对功率放大器210使用开/关键控进程来将信号发送到接收器。换句话说,当发射调制信号224被断言时,功率放大器210将在发射天线204上向外驱动载波信号220的频率。当发射调制信号224被否定时,功率放大器将不在发射天线204上向外驱动任何频率。
图6的发射电路还包括负载感测电路216,其将电力供应到功率放大器210且产生接收信号235输出。在负载感测电路216中,电阻器Rs上的电压降形成于电力输入信号226与到功率放大器210的电力供应228之间。由功率放大器210消耗的电力的任何改变将引起将由差分放大器230放大的电压降的改变。当发射天线与接收器(图6中未展示)中的接收天线处于耦合模式中时,由功率放大器210汲取的电流的量将改变。换句话说,如果发射天线204不存在耦合模式谐振,那么驱动辐射场所需的电力将为第一量。如果存在耦合模式谐振,那么由功率放大器210消耗的电力的量将上升,这是因为大量电力耦合到接收天线中。因此,接收信号235可指示耦合到发射天线235的接收天线的存在,且还可检测从接收天线发送的信号。另外,接收器电流汲取的改变可在发射器的功率放大器电流汲取中观测到,且此改变可用以检测来自接收天线的信号。
本发明的各种示范性实施例涉及一个或一个以上电子装置的电力管理,无线充电器的定位,及自动化无线充电。图7说明电子装置700,其具有接收器(图7中未展示;参见(例如)图5的接收器300)及至少一个相关联的接收天线702。电子装置700可进一步包括控制系统704及能量储存装置706。仅举例来说,能量储存装置706可包含电池。如本文中所描述,控制系统704可经配置以用于装置700的电力管理以及无线充电。
注意,虽然将控制系统704说明为与单个电子装置(即,装置700)相关联,但本发明不受如此限制。实情为,根据一个示范性实施例,控制系统704可分布于若干相关联的电子装置中。举例来说,用户可具有多个装置(例如,移动电话、个人媒体播放器,及蓝牙耳机),其中控制系统704分布于每一装置中,且经配置以管理所述多个装置中的每一者的电力消耗及无线充电。
图8说明包含多个装置700的系统750,其中每一装置包含控制系统704。作为一更特定实例,参看图8,一个装置700可包含用户的移动电话,且另一装置700可包含用户的便携式媒体播放器。根据下文参看图10更全面描述的另一示范性实施例,控制系统704可驻留于基于服务器的装置上,且可经配置以用于管理多个相关联的可以无线方式充电的电子装置的电力消耗及无线充电。
再次参看图7,根据一个示范性实施例,可监视存储在能量储存装置706内的电荷的电平。仅举例来说,控制系统704可经配置以确定并监视储存在能量储存装置706内的电荷的电平。此外,控制系统704可经配置以搜索位于可检测区内且经配置以用于发射无线电力的一个或一个以上合适的无线充电器并可能定位所述一个或一个以上合适的无线充电器。更具体地说,例如,在能量储存装置706的充电电平下降到低于阈值量后,控制系统704就可经配置以试图定位一个或一个以上合适的无线充电器。
图9说明系统800,其包括电子装置700及多个无线充电器802,多个无线充电器802位于装置700的可检测区内。因此,如上文所提到,电子装置700(且,更具体地说,控制系统704)可经配置以搜索并识别无线充电器802。注意,一个或一个以上无线充电器802可包含可充电装置,例如便携式媒体播放器。因此,装置700(其在一个实例中包含移动电话)可从另一装置(即,便携式媒体播放器)接收(“提取”)电力。
如上文所述,控制系统704可经配置以检测位于可检测区内的一个或一个以上无线充电器。仅举例来说,控制系统704可包含或可耦合到经配置以用于检测无线充电器的一个或一个以上接近传感器。根据另一示范性实施例,控制系统704可包含或可操作地耦合到全球定位系统(GPS),全球定位系统(GPS)可辅助装置700搜索一个或一个以上合适的无线充电器并定位所述一个或一个以上合适的无线充电器。下文将更全面地描述其中控制系统704包含或操作地耦合到用于辅助定位一个或一个以上无线充电器的GPS的实施例。
此外,在检测到至少一个无线充电器802后,控制系统704就可经进一步配置以实施用于相关联的装置700的合适的充电方案。更具体地说,控制系统704可使用充电分析以基于一个或一个以上因素而确定是否从可用无线充电器接收电荷。充电分析可包括分析一个或一个以上因素,如下文更完全描述。举例来说,充电分析可包含(仅举例来说)成本效益分析,在成本效益分析中,权衡充电成本与充电效益的得失。此外,在控制系统704检测到多个无线充电器的情况下,控制系统704可经配置以基于一个或一个以上因素而确定从所述多个所识别的无线充电器中的哪个无线充电器接收电荷,以使装置700的充电情况能够最佳化。又更具体地说,控制系统704可考虑与装置700、与装置700的用户、一个或一个以上可用无线充电器或其组合相关联的各种因素,且可响应于所述各种因素而确定是否接收电荷,且在确定接收电荷时,可确定从哪个无线充电器接收电荷以使装置700的充电情况能够最佳化。注意,在选择一个或一个以上无线充电器用于充电方案后,装置700及所述一个或一个以上选定的无线充电器可即刻使用一个或一个以上已知的且合适的协议(例如,信号交换协议)进行任何合适的验证过程。
仅举例来说,在充电分析中可考虑的因素可包括以下各项:装置700的电荷电平、装置700所需的电荷量、装置700的操作状态、对装置700充电的成本、对装置700充电的效益、与对装置700充电相关联的延迟、与一个或一个以上可用无线充电器相关联的可靠性问题、对装置700充电的预期时间长度、在进行装置700的后续充电之前的预期时间、装置700的电力需求量,及装置700正使用的应用程序。
注意,术语“充电方案”可包含“不充电方案”。换句话说,控制系统704可通过决定不对相关联的装置充电而实施用于所述装置的合适的充电方案。此外,控制系统704可通过决定对相关联的装置充电(且此外,决定利用哪个无线充电器用于所述充电)而实施用于所述装置的合适的充电方案。
如上文所提到,在控制系统704识别到至少一个可用无线充电器后,控制系统704就可在以下操作中考虑一个或一个以上因素:确定是否接收无线充电,且在确定接收无线充电时,确定从哪个无线充电器接收无线充电。如所属领域的技术人员将了解,各种无线充电器(例如,公共无线电力热点)可能需要用户在从其接收电荷之前支付附加费(即,基于订用的充电)或购买产品(例如,一杯咖啡)。如果附近的免费充电也可用,那么这些费用可能是用户所不希望有的。类似于基于订用的充电,基于广告的充电可允许用户在检视至少一个广告之后免费充电。此外,如果用户可在其它地方充电而无需检视广告,那么此情形可能为用户所不希望有的。
在挑选无线充电器中,充电速度也可为重要的。若干因素可影响发射速度,例如,同时充电的装置的数目。如果发射速度相对较慢,那么用户可能优选较快来源,即使需要费用也如此。另外,存在可影响用户希望在特定时间充电的若干因素,包括用户处于静止还是运动中,及装置的剩余电池寿命。在移动的同时对装置充电可为较困难的且,因此,用户可能偏好在到达目的地之后对装置充电。此外,如果电池的剩余寿命接近满格(full)且所有周围无线电力充电器由于某种原因而令人不满意(例如,均收取费用),那么用户可能偏好等待对装置充电。因此,控制系统704可经配置以考虑与所识别的充电器相关联的一个或一个以上因素(即,充电器是否为基于费用的充电器,充电器是否为基于广告的充电器,及充电器的充电速度),以便确定选择哪个无线充电器用于充电。
根据一个示范性实施例,控制系统704可经配置以在完成充电分析后,即刻自动地实施用于装置700的充电方案。根据另一示范性实施例,在完成充电分析后,控制系统704就可经配置以为装置700的用户提供所建议的充电方案,用户可接受或拒绝所建议的充电方案。注意,装置700可为装置用户提供所检测到的无线充电器的列表。此外,装置700可为用户提供关于所检测到的无线充电器的信息,包括位置、成本及发射速度。基于所提供的信息,用户可选择充电方案(例如,是否对装置700充电,且在选择对装置700充电时,利用哪个无线电力充电器)。注意,根据一个示范性实施例,装置700可经配置以延迟充电,直到装置用户已选择所要的无线充电器为止。
在另一示范性实施例中,控制系统704可经配置以使用一个或一个以上充电模式。所述充电模式可定义充电方案,例如,“无线充电模式”、“非无线充电模式”、“基于订用的充电模式”或“基于广告的充电模式”。控制系统704可经配置以基于若干参数(例如,时间、位置、暂时偏好等)而实施特定充电模式。此外,装置用户可进一步定义与特定充电模式相关联的一个或一个以上参数。此外,在充电模式之间切换可为自动的、半自动的(即,向用户提议以得到核准并于不存在用户超驰时切换)或手动的(即,用户起始)。根据此示范性实施例,例如,装置用户可决定在校内时(即,基于自动定位)使用基于订用的模式,且在特定时段期间(即,基于时间)(例如,在下午5与上午7之间)使用基于广告的模式。作为另一实例,用户可决定仅使用基于订用的模式以便避免广告。
根据另一示范性实施例,控制系统704可经配置以使本发明的示范性特征自动化。举例来说,控制系统704可经配置以使用基于概率及/或统计的分析来基于用户的先前决策而自动地选择无线电源或充电模式。举例来说,虽然一个用户可能不介意检视广告以便接收无线充电,但另一用户可能偏好为无线充电支付费用以便避免广告。作为另一实例,用户可偏好特定热点位置或热点公司。因此,控制系统704可经配置以基于用户的先前偏好而自动地选择充电方案。
另外,控制系统704可经配置以在发生一事件后即刻调适装置700的操作状态。举例来说,控制系统704可经配置以在相关联的能量储存装置的充电电平下降到低于阈值时,减小装置700的电力消耗。作为另一实例,控制系统704可经配置以减小相关联的接收器的敏感度或减小装置700的操作循环。控制系统704还可经配置以关闭或停用一个或一个以上应用程序(例如,GPS)。
如所属领域的技术人员将了解,例如移动电话等电子装置可包含时间管理应用程序(即,日历应用程序)。日历应用程序的实例可包括微软前景(MicrosoftOutlook)、谷歌日历(GoogleCalendars)、iCal等。根据本发明的一个示范性实施例,控制系统704可经配置以与同装置700相关联的电子日历同步,且因此,控制系统704可基于一个或一个以上电子日历条目而预测电力需求量。作为一个实例,如果装置700的用户具有相关联的电子日历上排定的会议呼叫,那么控制系统704可经配置以基于电子日历条目而确定所述会议呼叫可能需要多少电池电力,且在何时间需要电池电力。此外,如果控制系统704确定装置700的当前充电电平不足以用于所述会议呼叫,那么控制系统700可搜索一个或一个以上合适的无线充电器并可能地定位所述一个或一个以上合适的无线充电器。因而,可在所述会议呼叫之前对能量储存装置706充电。
此外,控制系统704可经配置以显示消息,以警告装置700的相关联的用户需要额外电力及需要电力之前的持续时间。控制系统704可通过有线方式或无线方式警告用户需要电力。
此外,根据另一示范性实施例,系统704可经配置以在预期有相关联的电子日历的一个或一个以上条目时修改(例如,减小)电力消耗。举例来说,在基于电子日历条目(即,会议呼叫)而确定会议呼叫可能需要多少电池电力之后,系统704可经配置以减小在会议呼叫之前装置700的电力消耗,以节省电力。注意,此示范性实施例可适用于其它情况,例如(仅举例来说)在休假之前对电子牙刷或剃刀充电,在教育课程之前对膝上型计算机充电,在日常慢跑之前对个人媒体播放器充电,或在喜爱的电视节目之前对远程控制器充电。
在一个示范性实施例中,控制系统704可包含预定义的操作参数。在另一示范性实施例中,用户可定制控制系统704的一个或一个以上参数。举例来说,控制系统704可使用户能够基于充电成本、充电阈值或其组合而修改用于充电的准则。此外,控制系统704可使所述用户能够(仅举例来说)在发生一个或一个以上事件后、在一个或一个以上特定时间或其任何组合时配置控制系统704的操作。在另一实例中,控制系统704可使用户能够定义何时启用或停用控制系统704。举例来说,为了促进顾虑到隐私,用户可致使控制系统704在相关联的装置处于特定位置时停用,使得其它装置无法检测到装置700。作为另一实例,装置用户可对装置进行编程以使其充当无线充电器,且可进一步识别将电力传送给哪一个或一个以上装置。举例来说,用户可仅允许从其移动电话对其蓝牙耳机充电。换句话说,蓝牙耳机可从移动电话提取电力。类似地,用户可允许媒体播放器将电力传送到用户所拥有的每个其它装置。作为另一实例,用户可定制控制系统704,使得蜂窝式电话被抑制不将电力提供给另一装置。
图10说明根据本发明的示范性实施例的包括基于服务器的装置的系统,所述基于服务器的装置包括控制系统。参看图10,根据如上文所提到的一个示范性实施例,控制系统704可驻留于基于服务器的装置854上,且可经配置以用于管理多个相关联的可以无线方式充电的电子装置852的电力消耗及无线充电。更具体地说,控制系统704可经配置以监视存储在一个或一个以上能量储存装置706内的电荷的电平,其中每一能量储存装置与一可充电的电子装置852相关联。此外,控制系统704可经配置以搜索一个或一个以上合适的无线充电器并在可能的情况下定位所述一个或一个以上合适的无线充电器。更具体地说,例如,在能量储存装置706的充电电平下降到低于阈值量后,控制系统704就可经配置以试图定位用于相关联的装置852的一个或一个以上合适的无线充电器。
根据一个示范性实施例,控制系统704可经配置以检测可用于对特定电子装置852充电的一个或一个以上无线充电器。此外,在检测到至少一个无线充电器(例如,无线充电器802;参见图9)后,控制系统704就可经进一步配置以实施用于特定电子装置852的合适的充电方案。更具体地说,控制系统704可使用充电分析以基于一个或一个以上因素而确定电子装置852是否应从可用无线充电器接收电荷。如上文所述,充电分析可包含(仅举例来说)成本效益分析,在成本效益分析中,权衡充电成本与充电效益的得失。此外,在控制系统704检测到多个无线充电器的情况下,控制系统704可经配置以基于一个或一个以上因素而确定所述多个所识别的无线充电器中的哪个无线充电器应将电力传送给电子装置852,以使装置852的充电情况能够最佳化。又更具体地说,控制系统704可考虑与电子装置852、与电子装置852的用户、一个或一个以上可用无线充电器或其组合相关联的各种因素,且可响应于所述各种因素而确定电子装置852是否应接收电荷,且在确定电子装置852应接收电荷时,确定应利用哪个无线充电器来使电子装置852的充电情况能够最佳化。
根据一个示范性实施例,控制系统704可经配置以在完成充电分析后,即刻自动地实施用于电子装置852的充电方案。根据另一示范性实施例,在完成充电分析后,控制系统704就可经配置以为装置852的用户提供所建议的充电方案,用户可接受或拒绝所建议的充电方案。注意,控制系统704可为装置用户提供所检测到的无线充电器的列表。此外,控制系统704可为用户提供关于所检测到的无线充电器的信息,包括位置、成本及发射速度。基于所提供的信息,用户可选择所要的无线充电器用于充电。注意,根据一个示范性实施例,控制系统704可经配置以延迟充电,直到电子装置用户已选择所要的无线充电器为止。
此外,控制系统704可经配置以使用一个或一个以上充电模式。如上文所提到,充电模式可定义充电方案,例如,“无线充电模式”、“非无线充电模式”、“基于订用的充电模式”或“基于广告的充电模式”。控制系统704可经配置以基于若干参数(例如,时间、位置、暂时偏好等)而实施特定充电模式。根据另一示范性实施例,控制系统704可经配置以使本发明的示范性特征自动化。举例来说,控制系统704可经配置以使用基于机率及/或统计的分析来基于用户的先前决策而自动地选择无线充电器或充电模式。另外,控制系统704可经配置以调适电子装置852的操作状态,以(例如)减小电子装置852的电力消耗。
此外,根据本发明的一个示范性实施例,系统704可经配置以与同装置852相关联的电子日历同步,且因此,控制系统704可基于一个或一个以上电子日历条目而预测电力需求量。此外,根据另一示范性实施例,控制系统704可经配置以在预期到相关联的电子日历的一个或一个以上条目时修改(例如,减小)装置852的电力消耗。
如所属领域的技术人员将了解,无线电力可具有有限范围,且对于移动应用,没有将始终存在可用于充电的无线充电器的保证。此外,因为无线电力场超过一定距离可迅速地减弱,所以电子装置(例如,装置700)可能并不始终有可能检测到无线充电器的位置。图11说明定位系统900,其包括控制系统704、数据库906及位置检测组件902。举例来说,位置检测组件902可包含GPS、A-GPS、一个或一个以上惯性传感器、WiFi系统、蓝牙系统,或其任何组合。参看图11,根据本发明的一个或一个以上示范性实施例,控制系统704可包含或可存取数据库906,数据库906可包括与无线充电器有关的信息(例如,基于位置的信息)。另外,控制系统704可包含或可耦合到位置检测组件902,位置检测组件902可确定装置700的绝对位置。注意,虽然将数据库906说明为位于远离装置700处,但本发明不受如此限制。实情为,装置700可包括数据库906。类似地,虽然将位置检测组件902说明为位于远离装置700处,但本发明不受如此限制。实情为,装置700可包括位置检测组件902。
使用具有与一个或一个以上无线充电器有关的数据的数据库906,控制系统704可为装置用户提供一个或一个以上无线充电器的位置及可能的到所述一个或一个以上无线充电器的方向。此外,如上文所提到,控制系统704可经配置以定位新的及/或未记录的无线充电器(例如,经由一个或一个以上接近传感器),且因此,控制系统704可将所定位的无线充电器的位置在数据库906中标以书签以供未来参考。类似地,控制系统704可经配置以搜集关于位置及时间的统计,且获悉用以接收电荷的优选时间。举例来说,如果装置700以规则模式移动,那么控制系统704可经配置以获悉装置700位于每一无线充电器的充电区中多久以及装置下一步将在哪里移动。作为另一实例,如果装置700位于无线充电器(其在数据库中指示为基于费用的充电器)的充电区内,那么控制系统704可使装置能够仅在装置700缺乏使得其移动到下一个免费无线充电器的足够的电力量时充电。关于位置及花费于无线充电器定位上的时间的统计还可由第三方来使用。此外,第三方可基于所述统计而向用户提供有目标的广告。数据库906还可通过从流行的加地理标记应用程序及其它网络服务接收信息来更新。
根据另一示范性实施例,控制系统704可经配置以使用航位推算法(如所属领域的技术人员将理解),以确定其相对于一个或一个以上无线充电器的位置。如所属领域的技术人员将了解,使用航位推算法的控制系统704仍可使用数据库906来寻找无线充电器以及记录新的无线充电器的发现。此外,根据另一示范性实施例,在确定装置700的位置后,控制系统704可即刻请求到无线充电器的方向。此外,在其中控制系统704远离装置700的示范性实施例中,装置700可向控制系统704发送(例如)呈与位置有关的一个或一个以上图片(例如,商店标志)的形式的信息。基于此所接收的信息及任选地其它信息(例如,小区ID)以及用户正移动的方向,控制系统704可经配置以识别附近的无线充电器的位置。
此外,在其中装置700包含位置检测组件902且装置700正由无线充电器充电的示范性实施例中,装置700可确定无线充电器的位置,且此后,将无线充电器的位置记录于数据库906中。注意,对于此示范性实施例,假定装置700与无线充电器(装置700正从其接收无线电力)具有相同位置。另外,因为每一装置700(其正从特定无线充电器接收无线电力)可向数据库906发送信息(例如,装置700当前正利用哪个无线充电器),所以数据库906可包含识别在任一时间多少个装置正从所述特定无线充电器接收电力的信息。因此,这可用于以下情况中:确定是否从所述特定无线充电器接收无线电力或是否定位另一、较不忙碌的无线充电器。此外,注意,无线充电器可经配置以向数据库906发送信息,其中所述信息可(仅举例来说)与无线充电器的利用率有关。
图12为说明根据一个或一个以上示范性实施例的方法980的流程图。方法980可包括在一个或一个以上受监视的能量储存装置中的一能量储存装置的电荷电平下降到低于阈值时,检测一个或一个以上无线充电器以用于对所述能量储存装置充电(通过标号984描绘)。此外,方法980可包括为与所述能量储存装置相关联的电子装置选择充电方案(通过标号986描绘)。
如所属领域的技术人员将了解,使用WiFi的室内定位通常可能需要寄存来自接入点的信标的所接收信号强度指示(RSSI)且接着查找RSSI到距离模型,或主动地向接入点发送包并使用到达时间信息来寻找范围。为了实现定位,连同了解接入点位置一起应用此些测距技术,以执行多点定位法,且确定最终位置。室内定位的一个重要挑战是缺乏足够的接入点。通常需要三个非共线的接入点(AP)处于台(STA)的范围内以实现精确定位。然而,在许多部署中,可能较不密集地部署接入点或可能并不知晓其位置。
如所属领域的技术人员将理解,无线充电器可位于室内或室外位置,例如(仅举例来说)位于机场、位于桌上(例如,位于商业街的饮食区)、位于咖啡店、等候室等,以为所述场所的消费者服务。根据本发明的各种示范性实施例,正通过无线充电器充电的装置可用以增加可用于在室外或室内环境中测距的信标信号的数目。因此,可改进位置准确度。
图13说明系统1000,其包括无线充电器1002及多个电子装置1004A、1004B及1004C。如图13中所说明,电子装置1004A及1004B位于无线充电器1002的充电区内。系统进一步包括数据库1006,如下文更全面描述。根据一个示范性实施例,位于无线充电器1002附近的电子装置1004C需要进行无线充电。
现在将描述系统1000的预期操作。无线充电器1002可经配置以经由其与位于相关联的充电区内的电子装置之间已建立的通信链路将充电标记发射到所述电子装置。更具体地说,无线充电器1002可经配置以将充电标记发射到电子装置1004A、电子装置1004B或电子装置1004A与电子装置1004B两者。根据一个示范性实施例,充电标记可包含用于无线充电器1002的唯一识别符。举例来说,所述唯一识别符可类似于识别无线装置的MAC地址。在此示范性实施例中,可将充电标记硬译码到无线充电器的存储器中。根据另一示范性实施例,充电标记可包含识别无线充电器1002的位置的本地坐标或全局坐标。在此示范性实施例中,可经由接口1008将充电标记编程到无线充电器1002中。
在接收到充电标记后,电子装置(例如,电子装置1004A、电子装置1004B,或电子装置1004A与电子装置1004B两者)可通过将充电标记整合于信标信号(例如,WiFi信标)中而充当接入点。如所属领域的技术人员将了解,WiFi信标可含有额外信息(例如,充电标记)(通过将充电标记编码到SSID、BSSID或信标信息元素中)。
此外,电子装置1004C可接收由电子装置1004A、电子装置1004B或电子装置1004A与电子装置1004B两者发射的信标信号。特定其中参考充电标志包含唯一识别符的示范性实施例,在接收到信标信号后,电子装置1004C可即刻在数据库1006中查找相关联的充电标记,数据库1006可包含唯一识别符到坐标(例如,本地坐标或全局坐标)的映射。此后,电子装置1004C可通过其从中接收信标信号的电子装置(例如,电子装置1004A或电子装置1004B)测距,以确定其相对位置。注意,假定无线充电器1002与电子装置1004A及1004B的位置相同。此外,特定参考其中充电标志包含本地坐标或全局坐标的示范性实施例,在接收到信标信号后,电子装置1004C可即刻使用所接收的信标信号中所包括的位置信息通过其从中接收信标信号的电子装置(例如,电子装置1004A或电子装置1004B)测距,以确定其相对位置。
根据其中充电标记包含唯一识别符的另一示范性实施例,在从无线充电器1002接收到充电标记之后,位于无线充电器1002的充电区内的电子装置(例如,电子装置1004A或1004B)可在数据库1006中查找相关联的充电标记,如上文所提到,数据库1006可包含唯一识别符到坐标(例如,本地坐标或全局坐标)的映射。因此,假定电子装置(例如,电子装置1004A)具有与无线充电器1002相同的位置,电子装置(例如,电子装置1004A)可确定其自身的位置。此后,电子装置(例如,电子装置1004A)可将其位置用信标发送到需要定位的任何其它电子装置(例如,电子装置1004C)。因此,在此示范性实施例中,电子装置1004A可能不需要存取数据库1006。在从电子装置1004A接收到信标信号后,电子装置1004C可即刻确定其相对位置。
图14为说明根据一个或一个以上示范性实施例的方法1010的流程图。方法1010可包括在位于无线充电器的充电区内的至少一个电子装置处接收与所述无线充电器相关联的充电标记(通过标号1012描绘)。方法1010可进一步包括将其中整合有充电标记的信标信号发射到至少一个其它电子装置,以使所述至少一个其它电子装置能够利用所述至少一个电子装置作为接入点(通过标号1014描绘)。
上文参看图13及图14所描述的示范性实施例可利用充电装置来动态地增加环境中的信标信号或测距装置的数目。因此,定位准确度可得以增强,这是因为电子装置可通过一个或一个以上其它电子装置来测距以增强位置估计。

在一个或一个以上示范性实施例中,可以硬件、软件、固件或其任何组合实施所描述的功能。如果以软件实施,那么所述功能可作为一个或一个以上指令或代码存储在计算机可读媒体上或经由计算机可读媒体来传输。计算机可读媒体包括计算机存储媒体与通信媒体两者,通信媒体包括促进计算机程序从一处到另一处的传送的任何媒体。存储媒体可为可由计算机存取的任何可用媒体。举例来说且并非限制,此计算机可读媒体可包含RAM、ROM、EEPROM、CD-ROM或其它光盘存储装置、磁盘存储装置或其它磁性存储装置,或可用以运载或存储呈指令或数据结构形式的所要程序代码并可由计算机存取的任何其它媒体。并且,严格地说,任何连接均被称为计算机可读媒体。举例来说,如果使用同轴电缆、光纤缆线、双绞线、数字订户线(DSL)或例如红外线、无线电及微波等无线技术从网站、服务器或其它远程源传输软件,那么同轴电缆、光纤缆线、双绞线、DSL或例如红外线、无线电及微波等无线技术包括于媒体的定义中。如本文中所使用,磁盘及光盘包括压缩光盘(CD)、激光光盘、光学光盘、数字多功能光盘(DVD)、软性磁盘及蓝光光盘,其中磁盘通常以磁性方式再现数据,而光盘通过激光以光学方式再现数据。上述各项的组合也应包括在计算机可读媒体的范围内。
