### 特征比对表格

技术特征描述以及公开性判断结果对比文件原文引用公开性论述
**技术特征A《直接公开》**<br>所述无线电力发射器经配置以将电力传递到具有无线电力接收器的装置。[001] It is more convenient to be able to power portable devices without the need to plug in a traditional power cable into the device. For example some wireless power systems include a portable device that when placed near a wireless power supply unit can receive power without the need for a direct electrical contact. <br>[089] Figure 1 shows an example of a wireless power system 100, which uses electromagnetic induction. There is a wireless power supply 102 which takes electrical power and transmits this power to a portable device 104. <br>[091] Figure 2 shows a wireless power supply 200 of one embodiment of the invention. ... If there is a valid device requiring power and no foreign objects present, then the control unit 208 will activate the Inverter 210 to supply current to the tank circuit, which includes the primary coil 212 and capacitor 214, to deliver power to the portable device (not shown).对比文件明确描述了无线电力系统,其主单元(primary unit/wireless power supply)通过电磁感应的方式,向便携式设备(portable device)无线传输电力。该便携式设备即为具有无线电力接收器的装置。这与目标专利中“无线电力发射器经配置以将电力传递到具有无线电力接收器的装置”的技术特征相同,且作用均为进行无线电力传输。因此,本领域技术人员能毫无疑义地得出该技术方案,该特征被直接公开。
**技术特征B《直接公开》**<br>所述设备包括:驱动器,其经配置以产生驱动信号以驱动所述无线电力发射器输出无线电力场。[089] ... The down-converted voltage is used to drive an Inverter 110. The Inverter 110 generates an AC voltage which is applied to the tank circuit, which includes a capacitor 114 and a primary coil 112. <br>[091] ... the control unit 208 will activate the Inverter 210 to supply current to the tank circuit, which includes the primary coil 212 and capacitor 214, to deliver power to the portable device (not shown).对比文件中的逆变器(Inverter 110, 210)接收直流电压并产生交流电压信号,该交流电压被施加到包含初级线圈的谐振回路(tank circuit),从而驱动初级线圈产生用于电力传输的磁场(即无线电力场)。逆变器在此起到产生驱动信号以驱动无线电力发射器(即初级线圈)输出无线电力场的作用,与目标专利中驱动器的作用相同。因此,该特征被直接公开。
**技术特征C《隐含公开》**<br>传感器,其经配置以感测所述驱动器所汲取的电力量,从而产生感测信号。[092] Foreign objects may be detected using a method disclosed in GB2414121, which is incorporated herein by reference. If a valid device is detected, then it communicates its power requirement to the Wireless Power Supply 200. The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement communicated by the device. <br>[180] ... The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement of the device.对比文件描述了无线电力供应单元测量从初级线圈汲取的功率(power being drawn from the primary coil)。为了测量功率,必然需要配置相应的传感器(如电流传感器、电压传感器或其组合)来感测驱动初级线圈的电路(如逆变器)所汲取的电流和/或电压,从而产生表征电力量的感测信号。尽管对比文件未明确描述“传感器”这一元件,但测量功率这一功能必然隐含了感测电力量的传感器的存在。本领域技术人员能够毫无困难地从“测量功率”这一公开内容中合理推断出需要使用传感器来产生感测信号。因此,该特征被隐含公开。
**技术特征D《直接公开》**<br>通信单元,其经配置以从所述无线电力接收器接收指示所述无线电力接收器所接收的电力的改变的信号。[092] If a valid device is detected, then it communicates its power requirement to the Wireless Power Supply 200. <br>[095] ... The device could then authenticate on the second `ping`. <br>[179] ... If the control unit 208 receives a signal that a device is present... <br>[180] ... If the control unit 208 receives a signal that a device is present...对比文件多次提及有效设备(valid device)与无线电力供应单元进行通信,例如通信其功率需求(power requirement)或发送表示其存在的信号(signal that a device is present)。这种通信指示了接收器端的状态,可隐含其接收电力的状态。特别是在检测异物时,需要比较线圈汲取的功率与设备通信的功率需求,这直接意味着通信单元接收到了来自接收器的、指示其所接收电力(或其需求,反映了所接收电力状况)的信号。因此,本领域技术人员能直接得出通信单元接收来自接收器信号的技术方案。该特征被直接公开。
**技术特征E《隐含公开》**<br>所述信号包含关于电流的改变的方向、电压的改变的方向以及所述无线电力接收器所接收的电力的改变的量值的信息。[092] ... The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement communicated by the device. <br>[180] ... The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement of the device.对比文件公开了设备会通信其功率需求,并且发射器会测量初级线圈汲取的功率以进行比较。为了进行有效的比较和识别(如区分设备类型或检测异物),信号中包含关于功率改变的量值信息是必要且合理的延伸。虽然对比文件未明确提及信号中包含“电流改变方向”和“电压改变方向”的具体信息,但在无线电力传输系统中,接收器所接收电力的改变必然体现为接收端电压和/或电流的改变。本领域技术人员在实现功率监测和比较功能时,完全有可能且合理地从接收器获取包含这些更具体参数(量值、方向)的信号,以便进行更精确的分析。因此,该特征被隐含公开。
**技术特征F《隐含公开》**<br>控制器,其经配置以基于所述感测信号而监视所述驱动器所汲取的电力的改变。[092] The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement communicated by the device. <br>[180] The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement of the device.对比文件明确描述了无线电力供应单元(通过其控制单元)测量(measures)从初级线圈汲取的功率。测量功率即意味着监视功率的变化。结合对技术特征C的论述,测量功率需要基于传感器产生的感测信号。因此,对比文件公开了控制单元(控制器)基于感测信号(尽管未明示)来监视所汲取电力(来自初级线圈,其驱动源为逆变器)的改变。该功能是直接公开的测量与比较过程的一部分。因此,该特征被隐含公开。
**技术特征G《隐含公开》**<br>且至少部分地基于电流的改变的方向、电压的改变的方向、所述无线电力接收器所接收的电力的改变的量值以及所监视的所汲取的电力的改变的比较来识别物体的类型。[092] ... In one embodiment, if there is no significant difference between the two values then the wireless power supply 200 determines that there is a valid device and no foreign objects present and therefore enables full power delivery to the device. <br>[095] ... It is also able to work if both a foreign object and a valid device are placed at the same time. <br>[181] ... whether there is a foreign object present. <br>[203] ... Another possible class of system is radio frequency identification (RFID) and associated technologies such as Near Field Communications (NFC) and contactless smart cards.对比文件公开了系统能够识别“有效设备”(valid device)和“异物”(foreign object),并提及了RFID/NFC装置作为另一种系统类型。识别过程基于对从初级线圈汲取的功率与设备通信的功率需求进行比较。要进行这种比较并区分不同类型的物体(如有效设备、金属异物、NFC卡),逻辑上需要分析功率、电流、电压等参数的变化趋势(方向)和大小(量值)。虽然对比文件没有明确列出“电流改变方向、电压改变方向”作为比较参数,但本领域技术人员知道,功率是电压和电流的乘积,功率的比较和分析必然涉及对电压和电流变化的考量。因此,基于所汲取功率和接收信号(含功率信息)的比较来识别物体类型的功能已被公开,而为实现更精确的识别(如目标专利所述区分NFC、金属等),采用电流/电压变化的方向和量值作为比较基础,是本领域技术人员在已公开的“功率比较识别”框架下能够合理推演和实现的技术方案。因此,该特征被隐含公开。
**技术特征H《隐含公开》**<br>其中所述控制器经配置以将所汲取的电力的所述改变与第一阈值进行比较且将所述所接收的信号与第二阈值进行比较。[092] ... if there is no significant difference between the two values... <br>[180] ... If there is no significant difference between the two then the wireless power supply 200 determines that there is a valid device and no foreign objects...对比文件公开了将测量的汲取功率与设备通信的功率需求值进行比较,并判断差异是否“显著”(significant)。这里的“显著差异”即隐含了使用阈值进行比较的概念。将“所汲取电力的改变”与一个阈值(第一阈值)比较,以及将“所接收的信号”(例如其包含的功率需求或实测接收功率)与另一个阈值(第二阈值)比较,是实施这种“差异显著性判断”的常规且直接的技术手段。本领域技术人员能够从“比较两个值并判断差异是否显著”的公开内容中,毫无困难地推断出可以设置和使用阈值来完成此判断。因此,该特征被隐含公开。
**技术特征I《直接公开》**<br>其进一步包括在超过所述第一阈值和第二阈值中的至少一者时调整所述无线电力场的输出功率。[091] ... If there is a valid device requiring power and no foreign objects present, then the control unit 208 will activate the Inverter 210 to supply current to the tank circuit... to deliver power... <br>[092] ... if there is no significant difference between the two values then the wireless power supply 200 determines that there is a valid device and no foreign objects present and therefore enables full power delivery to the device. <br>[181] ... If there is [a foreign object] then the system goes back to the start 1800.对比文件明确描述了系统的工作逻辑:当识别出有效设备且无异物时,则启用逆变器进行全功率传输(调整至正常输出功率);当检测到异物时,则不进行功率传输或返回待机状态(调整至低/零输出功率)。这个决策过程是基于对测量值和通信值的比较结果(可理解为与阈值的比较结果)做出的。例如,当比较结果“无显著差异”(可视为未超过某个差异阈值)时,调整输出功率至全功率;当检测到异物存在(可视为超过某个存在阈值)时,调整输出功率至低/零功率。这直接公开了基于比较结果(对应阈值判断)来调整无线电力场输出功率的技术特征。因此,该特征被直接公开。
**技术特征J《隐含公开》**<br>其中所述传感器经配置以感测所述驱动器所汲取的电力的初始水平,且所述控制器经配置以基于所感测的初始水平来确定所述驱动器所汲取的电力的基线值。[096] At point K, the system performs a calibration inductance measurement. This is the inductance measurement that subsequent measurements will be compared to in order to trigger the Sense Circuit 206. This may take longer than a normal measurement as it is important to make sure that the calibration measurement is a valid one and not a rogue measurement. <br>[123] The calibration routine may set the upper and lower thresholds in order to trigger the Sense Circuit 206.对比文件详细描述了“校准”(calibration)过程,即在无负载或已知状态下进行测量,并将该测量值存储作为后续比较的基准(baseline)。虽然校准直接针对的是感应电路的振荡频率(用于检测电感变化),但该原理同样适用于功率监测。为了检测“所汲取电力的改变”,必然需要先建立一个基线值(baseline value)。本领域技术人员为了实施功率变化的监视,会毫无疑义地采用相同的校准原理:使用传感器感测初始状态下的电力水平,并由控制器基于该感测值确定基线值。这是检测任何参数变化的常规前置步骤。因此,该特征被隐含公开。
**技术特征K《直接公开》**<br>其中所述控制器经配置以基于所述感测信号与基线值的比较来确定所汲取的电力的所述改变。[096] ... This is the inductance measurement that subsequent measurements will be compared to in order to trigger the Sense Circuit 206. <br>[123] The calibration routine may set the upper and lower thresholds in order to trigger the Sense Circuit 206. <br>[162] ... If this value changes, between two consecutive readings then the Sense Circuit 206 determines that an inductance change has occurred...对比文件明确公开了将当前的感测信号(如振荡频率的读数、峰值检测器输出值)与先前存储的校准值(基线值)进行比较,从而确定是否发生了变化(change)。对于功率感测,该原理完全适用。控制器配置为将当前感测到的电力量与基线值进行比较,以确定改变量,这是对比文件已公开的比较方法的直接应用。因此,该特征被直接公开。
**技术特征L《隐含公开》**<br>其中所述指示所述无线电力接收器所接收的电力的改变的信号是基于所述无线电力接收器所接收的电力的测得量相对于所述无线电力接收器所接收的电力的基线量的比较来确定,且其中所接收的电力的所述基线量是由所述无线电力接收器预先确定。[092] If a valid device is detected, then it communicates its power requirement to the Wireless Power Supply 200.对比文件公开了无线电力接收器(便携设备)向发射器通信其“功率需求”(power requirement)。这个“功率需求”可以理解为接收器基于其自身状态(如电池电量、负载需求)确定的一个值,它间接或直接反映了接收器期望或正在接收的电力水平。虽然对比文件没有明确描述接收器会测量自身接收的电力并与一个自定的基线比较后再发出信号,但本领域技术人员可以理解,接收器要确定其功率需求,必然需要对其自身的电力状况(接收的电力)进行某种评估。这种评估过程隐含了可能与一个内部参考值(基线量)进行比较。因此,由接收器预先确定一个基线量或参考值,并基于实测与基线的比较来生成发送给发射器的信号,是本领域技术人员在实现设备通信功率需求功能时能够合理采用的技术手段。该特征被隐含公开。
**技术特征M《隐含公开》**<br>其中所述控制器经配置以确定电流的改变的方向、电压的改变的方向以及所述驱动器所汲取的电力的所述改变的量值,且其中所述控制器经配置以至少部分基于所述电流的改变的方向、所述电压的改变的方向和所述量值来识别物体的所述类型。[092] ... The wireless power supply 200 measures the power being drawn from the primary coil 212 and compares it to the power requirement communicated by the device. In one embodiment, if there is no significant difference between the two values then the wireless power supply 200 determines that there is a valid device and no foreign objects present... <br>[180] ... If there is no significant difference between the two then the wireless power supply 200 determines that there is a valid device and no foreign objects...如特征G所述,对比文件公开了基于功率比较来识别物体类型(有效设备 vs 异物)。要确定“功率”的改变量值,控制器必然需要处理来自传感器的、反映电流和电压的感测信号。虽然对比文件聚焦于“功率”这一综合参数,但确定功率必然涉及对电流和电压的测量。本领域技术人员知道,不同类型的物体(如感性负载、容性负载、电阻性负载)对驱动电路的影响会体现在电流和电压变化的特定方向和比例关系上。因此,为了实现更精细的物体类型识别(如目标专利中区分金属、NFC、授权/未授权接收器),控制器配置为分析电流和电压变化的方向及量值,是对于已公开的“功率比较识别”方法的合理深化和具体化。这是在对比文件给出的识别框架下,本领域技术人员通过常规实验和分析能够得出的技术方案。因此,该特征被隐含公开。
**技术特征N《直接公开》**<br>其中所述物体是近场通信NFC装置、射频识别RFID装置、未授权的无线电力接收器、经授权的无线电力接收器和金属物体中的一者。[092] ... whether there is a foreign object present. <br>[095] ... It is also able to work if both a foreign object and a valid device are placed at the same time. <br>[181] ... whether there is a foreign object present. <br>[203] Another possible class of system is radio frequency identification (RFID) and associated technologies such as Near Field Communications (NFC) and contactless smart cards. <br>[204] Figure 46 shows an example of the invention being used in an RFID system (applicable to NFC and other contactless payment systems).对比文件明确提到了系统需要识别的物体类型包括:“有效设备”(valid device,即经授权的无线电力接收器)、“异物”(foreign object,可包含金属物体),并在其他应用场景中专门指出了RFID标签/NFC装置。这些正是目标专利权利要求中列举的物体类型。因此,对比文件直接公开了识别这些类型物体的技术特征。
**技术特征O《隐含公开》**<br>其中所述控制器经配置以监视所述驱动器所汲取的电流的改变。[092] The wireless power supply 200 measures the power being drawn from the primary coil 212... <br>[180] The wireless power supply 200 measures the power being drawn from the primary coil 212...对比文件公开了测量从初级线圈汲取的“功率”(power)。在电路中,测量功率通常需要同时测量电压和电流,或者直接测量电流并结合已知或测量的电压。因此,监视功率的改变必然隐含了监视电流的改变(以及电压的改变)。特别是对于驱动器电路(如逆变器),其汲取的电流是反映负载变化的关键参数。本领域技术人员为了实现功率测量功能,必然会配置电路来监视驱动电流的变化。因此,该特征被隐含公开。
**技术特征P《隐含公开》**<br>其中关于所述电压的改变的方向的所述信息包含在所述无线电力接收器的电压调节器的输入处接收的电压的改变的量值和方向。[092] If a valid device is detected, then it communicates its power requirement to the Wireless Power Supply 200.对比文件公开了接收器向发射器通信信息,例如其功率需求。接收器的功率需求与其内部工作状态相关,而电压调节器输入处的电压是反映接收功率水平的关键参数。本领域技术人员知道,在无线电力接收器中,通常包含整流和电压调节电路。接收器为了准确通信其功率状态或需求,非常有可能测量其电压调节器输入处的电压,并将该电压的变化信息(量值和/或方向)包含在发送给发射器的信号中。这是实现精确功率管理和通信的常规技术手段。因此,该特征被隐含公开。
