Description

用于去激活非接触式装置的方法
技术领域
本发明大体来说涉及用于借助射频识别装置(RFID)或其它识别装置(例如，“智能卡”)存取或鉴别电子装置或电子文档内的数据的识别装置、系统及方法。
背景技术
自动识别技术用于帮助识别人或物件且自动地提供关于所述人或物件的数据。通常，经鉴别或经证明的文档呈现为向个别人授予服务或利益的基础，例如，当使用来自国家、地方及联邦政府机构的护照或签证时。RFID标签或嵌入式装置可用于证明法律文档或确保文档不是伪造的，例如由美国国防部使用的共用存取卡(CAC)。
一种早期的技术是条形码序列号系统。然而，条形码不能存储关于个别人或物品的详细信息，例如到期日(例如，关于食品或户照签证)。另一识别技术(包含RFID装置、RFID电路及RFID标签)目前经制造并用于追踪多种物品和材料。RFID装置还可在嵌入到(例如)信用卡中时用于追踪交易。非接触式智能卡技术用于需要保护私人信息及/或递送安全交易的应用中，例如交通费支付卡、政府及公司识别卡、电子护照及签证，以及金融支付卡。可以多种形式(如，塑料卡、手表、钥匙链、文档及其它手持式装置)使用非接触式智能卡技术，例如将其嵌装到移动电话或个人数字助理中。
新兴的RFID技术采用射频(RF)无线或非接触式链路，且RFID装置可包含嵌入式计算机芯片。RFID技术允许对人或物件进行识别且允许将详细信息存储在个别RFID装置中。例如，一种实施方案可包含嵌入在电子护照的页面或封面中的安全微控制器。其它实例包含驾驶执照、出生证明及婚姻证明。其所有者的个人信息(例如，照片、签名、指纹及其它生物统计学数据的经密码编码的所签署副本)可安全地存储在RFID装置中。与机器可读护照的通信可以是非接触式的。目前应用于信用卡及支付行业中的ISO/IEC 14443标准可用于例如电子护照的授权文档中。通常，可根据数据传送速率要求及其它因素使用多种通信信道或频率。
RFID可具有包含在所述装置中的电池，或可以是无源的，具有由来自RFID阅读器的磁场所驱动的非接触式电源。通常，本身不具有电池或电源的RFID装置依赖于从RFID阅读器的RF信号获得其电力来操作。当将所述RFID装置引入到所述阅读器的电磁场中时，所述RFID装置中的IC芯片通电。一旦所述IC芯片通电，便在所述卡与所述阅读器之间起始并建立无线通信协议以用于数据传送。新式的电子护照嵌入一种类型的智能卡技术，所述技术不同于正用于追踪产品的较简单的RFID标签。RFID标签通常将仅发送存储在所述RFID标签中的ID编号。基于ISO/IEC 14443规范的非接触式智能卡技术在RFID装置的几英寸范围内施加13.56MHz的低功率射频信号时通电。可使用其它频率，例如，125KHz信道、134KHz信道或使用915MHz的载波。
智能卡技术界定通信协议，且RFID装置可接收命令并更新存储在所述RFID装置中的信息。通常将加密及安全证明用于例如电子护照的应用中来抵抗安全攻击，且某些应用需要长达10年或更长时间的无错误操作。如果将非接触式装置附加在ID文档上，则其通常在所述文档的整个寿命期间保持可操作。例如，电子护照可含有与数个国家的签证相对应的数个可操作非接触式RFID装置。需要多个证明的单个文档可含有数个RFID装置。目前，如果将非接触式RFID装置附加到文档，则所述RFID装置在所述文档的整个寿命期间保持活动。
参照图1，现有技术RFID装置100含有：接收天线元件101、振荡器电路102、电力电路103、时钟电路104、控制电路105及传输或发送电路106以及发送天线107。振荡器电路102可由RF匹配无源组件构成，例如电感器及电容器。天线101上所接收的交流电流(AC)信号由电力电路103进行整流以产生直流电流(DC)电流源来提供为RFID装置100中的其它电路供电的电压源。时钟(提取)电路104提取用于对RFID装置100所使用的组件及信号进行时钟计时的时钟或定时信号。控制电路105可控制发送电路106向RFID阅读器(未显示)发送所存储的数据(识别)信息。RFID装置100中含有的其它电路可包含：含有ID信息的存储器、接口电路及传输电路。通常，所述电路将读取识别号、识别码或存储在所述RFID装置中的其它信息，且然后将所存储的ID信息传输到所述RFID阅读器。
维加(Vega)等人的标称为“用于静电射频识别标签的最优化电路的方法及设备”(″Method And Apparatus For An Optimized Circuit For An Electrostatic Radio FrequencyIdentification Tag″)的美国专利第6,147,605号中论述了RFID标签的振荡器。然而，维加的缺点在于不能完全去激活所述装置。约翰逊的标称为“通过以降低的功率状态操作的RF阅读器单元对RFID装置的检测”(″Detection Of An RFID Device By An RFReader Unit Operating In A Reduced Power State″)的美国专利第6,476,708号论述了RFID标签中的激励信号产生器及激活电路。触发器开关使RF发送应答机在降低的功率状态与增加的功率状态之间来回切换。然而，约翰逊所遭受的缺点是，由于在没有功率信号的情况下不能维持所述触发器状态而无法持久地去激活所述装置。
例如，需要具有一种可停用或去激活的非接触式装置，例如，在电子护照中无效或已到期的签证。
发明内容
本发明的例示性实施例描述一种RFID装置，其具有由存储在存储器装置中的逻辑状态驱动的短路电路。所述存储器装置中所存储的逻辑状态确定启用还是停用电力电路及/或天线接口电路，从而对应地确定去激活还是激活所述RFID装置。
附图说明
图1是RFID装置中的现有技术调制控制的框图。
图2A及2B是RFID装置中的例示性天线接口电路或振荡电路的示意图。
图3是用于去激活RFID装置的例示性电路的框图。
图4是能够去激活RFID装置的装置的例示性电路图。
具体实施方式
呈现一种用于去激活无效非接触式识别装置或去激活识别装置的方法及装置或电路。根据内部存储器装置的经编程状态来启用或停用识别装置。根据所述应用，去激活识别装置可能是必要的。去激活可能是需要的，使得在将来的交易中，或在所受权周期已到期的情况下，所述非接触式装置将不会干扰或混淆对其它非接触式装置的读取。例如，对于含有数个签证(电子识别装置)的护照来说，可能有一个签证到期。在此实例中，可能需要的是仅去激活所述到期签证。
RFID系统可由两个基本组件—RFID识别装置及RFID阅读器组成。通常，RFID阅读器向使用磁场或电磁场的RFID装置或标签发送RF信号，以既为所述卡供电，又在所述RFID装置与所述阅读器之间交换数据。当所述RFID装置或标签接收所述阅读器的信号时，所述RFID标签或装置向所述阅读器发送所存储的数据，且所述阅读器接收被编程到所述RFID装置或标签中的数据并对所接收的数据进行解码。某些无源RFID装置从阅读器信号中获得其所有电力，其中所述RFID装置仅在其处于所述阅读器的电磁场附近时加电。
RFID装置通常包含集成电路(IC)芯片及嵌入在所述RFID装置内的天线。RFID装置还可驻存在钥匙链内或例如护照的文档内。所述IC芯片可仅包含类似于条形码中的信息量的简单的编号、例如照片及个人生物统计学的多种详细信息，或其可包含用于执行从阅读器接收的命令的数字解码器。所述RFID装置内的IC芯片可包含：供电电路，其用于从来自阅读器的电磁信号中提取电力并调节所述电力；检测器，其用于将来自所述阅读器的信号解码；发射机，其用于将数据发送回到所述阅读器；防冲突协议电路；及至少足以存储识别(ID)码的存储器。
图1中的现有技术RFID电路缺少持久停用所述RFID装置的功能。例如，在现有技术中，即使护照内的RFID签证已到期，通常仍将需要物理地改变或破坏所述RFID来使其不能操作或起作用。每当现有技术RFID处在RFID阅读器附近的范围内时，所述RFID装置将加电并开始与所述阅读器通信。对于例如电子护照的应用来说，有必要去激活特定的RFID装置，或限制所述电子护照中有源RFID装置的数量。例如，对于含有数个RFID签证的护照来说，可有单个签证到期或失效。在此实例中，需要去激活签证或使其失效来限制已知犯罪者的旅行活动。在其它应用中(例如电子文档应用)，或对于授权存取安全区域的文档来说，需要持久地去激活所述文档中所含有的到期RFID装置。
参照图2A，并联谐振(LC)回路振荡或天线匹配电路用作天线(未显示)的接口电路200。选择电感器(L)201及电容器(C)202的值来提供合乎需要的振荡频率或匹配阻抗。所述电感值可包含耦合到天线的特定分量或部分，或所述电感值可仅是所述天线的电感值。其它无源及有源激励、谐振或振荡电路也可用于所述振荡器或匹配电路中，其中包含二极管、晶体管、频率控制电路，及反馈或放大装置的使用。对于在天线处接收的信号来说，还可使用多种调制技术，其中包含振辐调制、相位调制、频率调制或调制技术的组合。还可实施多种频率。
参照图2B，在RFID识别装置的例示性实施例中，可通过使用开关或短路电路203使所述振荡、匹配或接口电路发生短路来去激活接口电路200，短路电路203可向所述振荡或匹配电路组件(即，电感器201及电容器200)提供低阻抗或短路阻抗。短路电路203(或开关)与振荡或匹配电路组件并联耦合，从而将电容器202与电感器201之间的振荡AC能量传送放电。
参照图3，在RFID识别装置300的例示性框图中，接口电路301耦合到短路电路302。接口电路301含有至少一个振荡或匹配到天线(未显示)的组件。通常，IC电路用于接口电路301中。然而，还可使用例如匹配变换器的其它组件或例如二极管或晶体管的其它有源装置。短路电路302可由单个晶体管开关或多个晶体管开关构成。当短路电路302处于传导操作模式时，其提供阻止或暂停接口电路301中的组件与天线之间的能量传送的短路阻抗或电流路径。控制电路303激活或去激活短路电路302。控制电路303耦合到存储器电路304，所述存储器电路经编程以存储预先选定的逻辑值。所述经编程逻辑值确定控制电路303激活还是去激活短路电路302，而所述短路电路又去激活或激活接口电路301。电力电路305向RFID装置中的电路提供电源。所述电源是从接口电路301中产生的信号取得。产生于接口电路301中的信号通常是RFID阅读器通过天线产生的电磁波。
参照图4，RFID装置300的特定例示性实施例包括：(天线)接口电路301、短路电路302、控制电路303、存储器电路304及电力电路305。
接口电路301由电容器422(C1)及电感器421(L1)构成。所述接口电路耦合到接收交流电流(AC)信号的天线(未显示)。电感器421可以是匹配变换器，其具有耦合到天线的第一线圈及耦合到电容器422的第二线圈。所接收的AC信号用作电源，且还可用于接收命令及用于接收定时或时钟计时信息。
电力电路305包括配置为二极管且以桥接配置布置的供电晶体管401、402、403、404。电力电路305耦合到接口电路301并从来自天线(未显示)和接口电路301的信号获取电力。每一供电晶体管401、402、403、404均经配置以操作为二极管等效物。所述桥接配置将来自天线和接口电路301的AC信号转换到直流电流(DC)电源。所述电力电路向RFID装置中的电路提供电力。在图4中，所述DC供电线路表示为Vdd及Gnd。还可使用其它AC到DC转换配置，例如两个二极管的布置来代替使用全波桥接配置。
存储器电路304是单个可编程晶体管或存储器装置410，其经配置以维持经编程状态或维持所存储的逻辑状态。在向存储器电路304施加电力(供电的)或不施加电力(未供电的)的情况下，维持存储在存储器装置410中的经编程逻辑状态。存储器装置410可以是具有浮栅的快闪或EEPROM装置。通常，通过选择性地向浮栅晶体管施加编程电压来对其编程，所述编程电压迫使电子电荷进入到所述浮栅上或离开所述浮栅。在向可编程晶体管或存储器装置410施加或不施加电力或者施加或不施加电压的情况下，由电绝缘体环绕的浮栅保持或维持所述经编程电子电荷。或者，所属技术领域的技术人员应认识到，可为存储器装置410采用另一种类型的状态或逻辑“存储”装置，例如可熔断链。
通过向存储器装置410施加预定的编程电压来对存储器装置410编程。例如，通常可通过向控制栅极线411施加高于供电电压(Vdd)的电压而使电子加速到达所述浮栅上。然后，存储器装置410已编程为“关闭”状态(不传导)。或者且通常，可通过向控制栅极施加低于接地参考(Gnd)的电压而将电子从所述浮栅移除。然后，存储器装置410已编程为“接通”状态(传导)。在此特定例示性实施例中，当存储器装置410已编程为以“关闭”状态操作时，所述RFID装置将被去激活，且或者，当存储器装置410已编程为以“接通”状态操作时，所述RFID装置将被激活。
控制电路303耦合到存储器装置410。控制电路303及存储器装置410可由微处理器(未显示)驱动及编程，或由所述RFID装置内的其它电路(未显示)驱动及编程。例如，微处理器可响应于从RFID阅读器(未显示)接收的命令来驱动编程电路以对存储器装置410编程。类似地，所述RFID装置内的逻辑可辨识从RFID阅读器接收的命令序列并触发编程操作。
存储在存储器装置410中的逻辑状态指示应该激活还是去激活所述RFID装置。使用存储器装置410中的所存储逻辑状态的控制电路303驱动或控制短路电路302。控制电路303及存储器装置410由晶体管对405、406来供电、偏压或驱动。晶体管对405、406的每一晶体管均配置为二极管等效组件。晶体管对405、406耦合到接口电路301。晶体管对405、406还耦合到控制晶体管407。控制晶体管407耦合到短路电路302，且控制晶体管407驱动或控制短路电路302。偏压电阻器421耦合到控制晶体管407的栅极。
切换电路或短路电路302经配置以使电力电路305发生短路或经配置以使接口电路301发生短路。跨越电容器422施加接口电路301中的短路电路以阻止或暂停接口电路301进行振荡。所述短路电路由两个短路晶体管408、409构成，所述短路晶体管耦合到控制电路303且还耦合到电力电路305。短路晶体管408、409通常为高增益装置，例如，在集成电路装置中具有宽物理布局，以提供快速且可靠的短路操作。当短路晶体管408、409处于传导状态时，由短路晶体管408、409将低阻抗或短路施加到接口电路301，每一晶体管串联在Vdd与电容器422及电感器421的相对端之间。短路晶体管408、409还耦合到配置为电力电路中的二极管的两个供电晶体管403、404并使其短路。
继续参照图4，当将RFID装置带到极接近RFID阅读器处时，在天线(未显示)及接口电路301中产生信号。在跨越电容器422的接口电路301的输出处产生信号。晶体管对405、406向控制晶体管407提供高偏压及驱动电压。如果存储器电路304中的经编程或所存储逻辑值导致存储器装置410处于“接通”状态或传导状态，则控制晶体管407的栅极将被拉到接地，从而关断控制晶体管407。当控制晶体管407处于关闭状态时，短路晶体管408、409也将处于关闭状态或不传导状态，且将激活RFID装置。电力电路305将正常操作，向RFID装置中的电路提供电力，且激活RFID装置。如果存储器电路304中的经编程或所存储逻辑值导致存储器装置410处于“关闭”状态或不传导状态，则控制晶体管407的栅极将由偏压电阻器421拉到高状态，从而接通控制晶体管407。当控制晶体管407处于接通状态时，短路晶体管408、409将被驱动到接通状态或传导状态。电力电路305及接口电路301将被短路或钳位，不向RFID装置中的电路提供电力，且去激活RFID装置。
本发明例示性实施例中所呈现的是RFID装置，根据所述RFID装置中的可编程存储器装置的经编程状态而启用或停用所述RFID装置。所属技术领域的技术人员应认识到，可在随附权利要求书的精神和范围内对本发明做出修改和变化，且通过阅读及了解本文中呈现的描述，所属技术领域的技术人员将明了许多其它实施例。例如，可使用实施AC到DC电力电路的等效电路或方法。所述控制晶体管、存储器晶体管及(偏压)晶体管对的组合可经不同配置以提供相同的功能。所述接口电路或振荡器(LC)电路可包含调谐到天线的匹配RF变换器，或还可使用具有电容性或导电性特征的替代有源装置。同样，本发明并不一定限于所描述的特定RFID装置。本发明还可应用于具有用于供电及通信的连接器或触点或其它格式的ID卡。所描述的实施例及其等效物还可用于其它技术领域。
