| **技术特征A**：其包括：通过一或多个处理器获得移动装置在一或多个方向中的每一者上的加速度数据<br>**《直接公开》** | [0006] “a method that includes obtaining acceleration data for a mobile device in each of one or more directions.”<br>[0011] “one or more sensors configured to measure acceleration data for the mobile device in each of one or more directions.”<br>[0016] “receive acceleration data for a mobile device in each of one or more directions.”<br>[0087] “the process 700 begins at 701 with obtaining acceleration data for a mobile device... in each of one or more directions.” | 对比文件明确且多次公开了方法、装置及介质中包含“获得移动装置在一或多个方向中的每一者上的加速度数据”这一步骤。所属领域技术人员能毫无疑义地得出该技术特征。 |
| **技术特征B**：其中获得所述加速度数据涉及从所述移动装置的一或多个传感器接收所述加速度数据<br>**《直接公开》** | [0052] “the sensor suite 134 includes three linear accelerometers 236A, 236B and 236C, each of which measures linear acceleration ... along a particular axis of a mobile device coordinate system.”<br>[0087] “For example, in some implementations, the first linear accelerometer 236A can measure linear acceleration data along the first axis 338A ... the second linear accelerometer 236B ... and the third linear accelerometer 236C...” | 对比文件详细描述了传感器套件包含多个线性加速度计，用于测量沿装置坐标系统各轴线的加速度数据。获得加速度数据必然涉及从这些传感器接收数据，这是实施该功能的直接且必然的方式。 |
| **技术特征C**：经由所述一或多个处理器至少部分地基于所述加速度数据识别所述移动装置的使用情况，<br>**《隐含公开》** | [0076] “the phase offset or other parameters or characteristics of motion can change based on where and how the mobile device 100 is being carried during motion; that is, based on a particular use case.”<br>[0077] “In some implementations, the motion direction estimation module 666 identifies a use case based on an observed correlation of the acceleration components over a number of steps ... or, in some other implementation, over some duration of time.”<br>[00101] “In some implementations, the motion direction estimation module 666 identifies a likely use case; that is, a likely manner in which the mobile device is being carried by the pedestrian or a manner in which the pedestrian is moving.”<br>[00104] “identifying a use case for the mobile device based at least in part on the acceleration data.” | 对比文件多次提及“识别使用情况（identify a use case）”，并明确该识别至少部分地基于加速度数据（例如，基于加速度分量的观测相关性）。虽然对比文件主要描述了通过多个并行模块（每个针对一种使用情况）来处理，但其中也包含了识别使用情况的概念（例如，为选择/优化参数而识别）。因此，本领域技术人员能够合理推断出“至少部分地基于加速度数据识别使用情况”这一技术特征。 |
| **技术特征D**：所述使用情况对应于正携带所述移动装置的方式或携带所述移动装置的行人正移动的方式中的至少一者<br>**《隐含公开》** | [0076] “based on whether the mobile device 100 is being carried in a hand swinging forward and backward as the person walks, being carried out in front ..., being held at the person's ear ..., or being carried in the person's pocket, purse, or pack.”<br>[00101] “a likely manner in which the mobile device is being carried by the pedestrian or a manner in which the pedestrian is moving.” | 对比文件明确将“使用情况（use case）”定义为移动装置被携带的方式（如手中摆动、前方、耳边、口袋）或行人移动的方式（如行走、慢跑、跑步）。这完全对应于目标专利中“使用情况”的定义。 |
| **技术特征E**：经由所述一或多个处理器基于经识别使用情况而选择一或多个参数的集，<br>**《直接公开》** | [0077] “after a use case is identified, the motion direction estimation module 666 then adjusts the phase offset or other parameters ... to more accurately estimate the motion vector M.”<br>[00105] “In some implementations ... the motion direction estimation module 666 can retrieve a set of predetermined parameters stored or linked with the identified use case in the memory 132.”<br>[00106] “using the selected parameters to estimate the motion direction M” | 对比文件明确公开了在识别使用情况后，调整（即选择）参数集（如相位偏移等）以更准确地估计运动方向。还公开了从存储器中检索与所识别使用情况链接的预定参数集。因此，该特征被直接公开。 |
| **技术特征F**：其中所述参数的集包括所述加速度数据的垂直分量和水平分量之间的相位偏移，并且其中第一使用情况的相位偏移不同于第二使用情况的相位偏移<br>**《直接公开》** | [0075] “the motion direction estimation module 666 can ... cancel out the asymmetric components of the acceleration by leveraging the known or expected correlation (for example, the phase offset) between the forward/backward and vertical acceleration components.”<br>[0076] “the phase offset ... can change based on where and how the mobile device 100 is being carried during motion; that is, based on a particular use case.”<br>[0010] “each set of parameters includes a phase offset between vertical and horizontal components of the acceleration data.” | 对比文件明确将垂直与水平（前向/后向）加速度分量之间的相位偏移作为参数集的一部分（[0010]）。同时明确指出该相位偏移会基于使用情况（如设备被携带的位置和方式）而变化（[0076]）。因此，不同使用情况对应不同相位偏移的技术特征被直接公开。 |
| **技术特征G**：经由所述一或多个处理器基于所述加速度数据及对应于所述经识别使用情况的相应的参数集来计算所述移动装置相对于坐标系统的经估计运动方向<br>**《直接公开》** | [0006] “calculating, by a plurality of motion direction estimation modules ... a plurality of respective estimated motion directions for the mobile device relative to a coordinate system. ... each of the respective motion direction estimation modules uses a respective set of parameters and calculates the respective estimated motion direction based at least in part on the acceleration data and the respective set of parameters.”<br>[00106] “the motion direction estimation module 666 can analyze the orientation O and the remaining acceleration components ... to estimate, calculate or otherwise determine and output the motion vector M.” | 对比文件的核心内容就是通过多个运动方向估计模块，每个模块使用各自的参数集并基于加速度数据来计算相对于坐标系统的估计运动方向。这直接公开了目标专利的特征G。 |

In some such implementations, when the reliability metric falls below the threshold, the network interface is turned on or otherwise enabled...” | 对比文件明确公开了基于可靠性度量是否超过阈值来控制（开启或关闭）网络接口，以节省功耗或接收校准数据。 |
| **技术特征J**：所述网络接口经配置以与全球定位系统、卫星导航系统或其他定位或导航系统进行通信，<br>**《直接公开》** | [0039] “a network interface configured to communicate with a GPS, SNS, or other positioning or navigation system...”<br>[0044] “the network interface 114 can transmit and receive positioning data ... such as that received from a GPS or Satellite Navigation System (SNS)...” | 对比文件明确描述了网络接口被配置用于与GPS、SNS（卫星导航系统）或其他定位/导航系统通信。 |
| **技术特征K**：其中所述控制涉及在所述可靠性度量超过阈值的情况下关闭所示网络接口。<br>**《直接公开》** | [0039] “a network interface ... is turned off or otherwise disabled as long as the reliability metric for an estimated motion direction M is above a threshold value.” | 对比文件明确公开了当可靠性度量高于阈值时，关闭（或禁用）网络接口。这与目标专利的描述完全一致。 |
| **技术特征L**：其中识别使用情况包含将所述加速度数据与多个预定义使用情况的加速度特性相比较并选择所述预定义使用情况中为最佳匹配的一者，其中所述预定义使用情况中的每一者与相应的一或多个参数的集存储在一起或与相应的一或多个参数的集链接。<br>**《隐含公开》** | [00102] “the motion direction estimation module 666 identifies the use case by matching the acceleration, rotation or orientation data determined from the sensor suite 134 to acceleration, rotation or orientation data corresponding to predetermined use cases stored in a use case database in, for example, the memory 132. In some such implementation, the motion direction estimation module 666 can retrieve a set of predetermined parameters stored or linked with the identified use case in the memory 132.” | 对比文件公开了通过将传感器数据（包括加速度数据）与存储在数据库中的预定使用情况的数据进行“匹配（matching）”来识别使用情况，并在识别后检索与该使用情况“存储或链接（stored or linked）”的预定参数集。虽然“最佳匹配（best match）”的表述未明确出现，但“匹配”这一行为本身隐含了从多个预定情况中选择与之最相符的一者。因此，本领域技术人员能够合理推断出该技术方案。 |
| **技术特征M**：其中所述多个预定义使用情况包含：其中所述移动装置处于电话模式的使用情况<br>**《隐含公开》** | [0076] “based on ... being held at the person's ear while the person is using the mobile device 100 as a telephone...”<br>[00101] “based on ... whether a call is initiated, the motion direction estimation module 666 can determine that the mobile device 100 is being held near the person's ear.” | 对比文件提到了移动装置被持于耳边用作电话的使用情况，这对应于“电话模式”。虽然未使用“电话模式（phone mode）”这一确切术语，但描述了其实质内容。 |
| **技术特征N**：其中所述移动装置在口袋中的使用情况<br>**《隐含公开》** | [0076] “based on ... or being carried in the person's pocket, purse, or pack.”<br>[0027] “Figure 5B shows an example scenario in which a mobile device is being carried in a person's side pants pocket.” | 对比文件明确将移动装置被携带在“口袋（pocket）”中作为一种使用情况或场景。 |

| **技术特征S**：其进一步包含检测所述移动装置何时处于电话模式中，其中识别所述使用情况还基于所述移动装置是否处于所述电话模式中。<br>**《隐含公开》** | [00101] “based on ... whether a call is initiated, the motion direction estimation module 666 can determine that the mobile device 100 is being held near the person's ear.” | 对比文件提到基于呼叫是否启动（whether a call is initiated）来判断装置是否在耳边，这实质上是一种检测“电话模式”的方式。并且该信息用于确定使用情况（装置在耳边）。因此，该特征被隐含公开。 |
| **技术特征T**：其进一步包含确定所述移动装置相对于携带所述移动装置或所述移动装置所附接到的用户的位置，其中识别所述使用情况还基于所述移动装置的所述位置。<br>**《未公开》** | 对比文件中未提及“确定移动装置相对于用户的位置”这一特定步骤。对比文件识别使用情况主要基于运动数据（加速度、相关性）和设备状态（如是否通话），而非一个独立的“相对于用户的位置”确定步骤。 | 对比文件没有公开“确定移动装置相对于用户的位置”这一技术特征。虽然使用情况的识别结果（如“在口袋中”、“在手中”）隐含了位置信息，但目标专利要求的是一个明确的“确定位置”的步骤，并基于此步骤来辅助识别使用情况。对比文件缺乏这一明确的步骤教导。 |

| **技术特征V**：其中识别所述使用情况还至少部分地基于所述定向。<br>**《直接公开》** | [00101] “the motion direction estimation module 666 also can use non-movement related information to classify a current use case ... For example, based on a certain tilt of the mobile device 100 (as determined from rotation data or magnetic data from the gyroscopes 240 or magnetometers 242, respectively) ... the motion direction estimation module 666 can determine that the mobile device 100 is being held near the person's ear.” | 对比文件公开了基于设备的倾斜（由旋转或磁场数据确定，即定向数据）来判断使用情况（如装置在耳边）。因此，识别使用情况至少部分基于定向这一特征被直接公开。 |
