For example, the phase offset ... can change based on whether the mobile device 100 is being carried in a hand ... being held at the person's ear ... or being carried in the person's pocket, purse, or pack. Each of these scenarios also may be considered a particular use case. ... The phase offset ... may also change based on a change in speed, gait or cadence (for example, from walking to jogging to running) Each of these scenarios also may be considered a particular use case.<br>[0098] 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. For example, the motion direction estimation module 666 can use any of the linear acceleration, angular acceleration, or other rotation or orientation data to determine a likely use case. | 对比文件[0073]明确阐述了垂直与水平加速度分量之间的相位偏移会基于移动装置被携带的方式（例如，拿在手中、放在耳边、在口袋中）或用户的运动方式（例如，行走、慢跑、跑步）而变化，并明确指出这些场景可被视为特定的“使用情况”。[0098]进一步说明运动方向估计模块666可以利用线性加速度等数据来确定“可能的使用情况”。虽然对比文件没有使用“识别”一词来直接描述一个独立的“识别使用情况”的步骤，但其明确教导了：1）存在不同的使用情况；2）这些使用情况与加速度数据的特征（如相位偏移）相关联；3）运动方向估计模块可以利用加速度数据来确定使用情况。本领域技术人员能够合理地从这些内容中推断出，为了后续的参数选择或优化，需要首先基于加速度数据来识别或确定当前的使用情况。因此，技术特征C被对比文件隐含公开。 |

For example, the phase offset ... can change based on whether the mobile device 100 is being carried in a hand ... being held at the person's ear ... or being carried in the person's pocket, purse, or pack. ... The phase offset ... may also change based on a change in speed, gait or cadence (for example, from walking to jogging to running) Each of these scenarios also may be considered a particular use case.<br>[0098] ... 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. | 对比文件[0073]和[0098]明确将“使用情况”定义为移动装置被携带的方式（例如，在手中、在耳边、在口袋中）和/或行人移动的方式（例如，行走、慢跑、跑步）。这完全对应于技术特征D中“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”的描述。因此，技术特征D被对比文件直接公开。 |
| **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>**《隐含公开》** | [0074] 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 ... In some such implementations, 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>[0100] Once the use case is identified, the parameters used in the motion direction estimation module 666 can then be selected and optimized to obtain an accurate estimated motion direction M. | 对比文件[0074]和[0100]明确教导了在识别使用情况后，运动方向估计模块666会“调整（adjust）”或“选择和优化（selected and optimized）”参数（如相位偏移等）。虽然原文使用了“调整”和“优化”，但“选择一或多个参数的集”是进行调整或优化的必然前提和内在组成部分。本领域技术人员可以毫无疑义地理解，为了针对特定使用情况进行调整或优化，必须首先基于该使用情况从可能的参数集中进行选择。因此，技术特征E被对比文件隐含公开。 |
| **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》** | [0073] However, the phase offset between the vertical acceleration and forward/backward acceleration components can change based on where and how the mobile device 100 is being carried during motion; that is, based on a particular use case. For example, the phase offset ... can change based on whether the mobile device 100 is being carried in a hand ... being held at the person's ear ... or being carried in the person's pocket, purse, or pack. Each of these scenarios also may be considered a particular use case. The phase offset ... may also change based on a change in speed, gait or cadence (for example, from walking to jogging to running) Each of these scenarios also may be considered a particular use case. | 对比文件[0073]明确公开了：1）参数集包含垂直加速度分量和向前/向后（水平）加速度分量之间的相位偏移（phase offset）；2）该相位偏移会基于不同的使用情况（例如，拿在手中 vs 放在耳边 vs 在口袋中，或行走 vs 慢跑 vs 跑步）而变化，即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。这完全覆盖了技术特征F的全部限定。因此，技术特征F被对比文件直接公开。 |
| **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>**《隐含公开》** | [0074] ... after a use case is identified, the motion direction estimation module 666 then adjusts the phase offset or other parameters (for example, a window of time or number of steps within which to track and correlate acceleration data) to more accurately estimate the motion vector M.<br>[0100] Once the use case is identified, the parameters used in the motion direction estimation module 666 can then be selected and optimized to obtain an accurate estimated motion direction M.<br>[0103] ... using the selected parameters to estimate the motion direction M relative to a global coordinate system as, for example, described above. | 对比文件[0074]、[0100]和[0103]明确描述了在识别使用情况并选择/调整参数后，使用所选参数来估计相对于全局坐标系统的运动方向（M）。虽然原文没有将“基于加速度数据”和“基于参数集”在同一句话中并列描述计算步骤，但根据对比文件的整体教导，运动方向估计（例如通过特征分解分析加速度数据）必然要使用加速度数据，并且该估计过程会利用调整后的参数（如相位偏移）以提高准确性。本领域技术人员可以合理推断，计算经估计的运动方向是基于加速度数据以及对应于所识别使用情况的参数集来执行的。因此，技术特征G被对比文件隐含公开。 |

| **技术特征I：** 以及根据所述可靠性度量是否超过阈值来控制所述移动装置的网络接口，<br>**《直接公开》** | [0036] For example, in some implementations, to save power, a network interface configured to communicate with a GPS, SNS, or other positioning or navigation system is turned off or otherwise disabled as long as the reliability metric for an estimated motion direction M is above a threshold value. 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[0036]明确公开了根据可靠性度量是否超过阈值来控制移动装置的网络接口（具体为与GPS等系统通信的网络接口）：当可靠性度量高于阈值时关闭接口以省电，低于阈值时开启接口以接收校准数据。这直接公开了技术特征I。因此，技术特征I被对比文件直接公开。 |

| **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》** | [0099] For example, in some implementations, 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[0099]明确公开了运动方向估计模块通过将从传感器获得的数据（包括加速度数据）与存储在数据库中的预定义使用情况的数据进行匹配（matching）来识别使用情况。并且，在识别后，可以检索（retrieve）与所识别使用情况存储在一起或链接（stored or linked）的预定参数集。这完全公开了技术特征L中关于“将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最佳匹配的一者”以及“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链接”的技术方案。虽然“选择最佳匹配的一者”的表述未在[0099]中明确出现，但“匹配（matching）”数据的行为必然隐含了选择匹配度最高（即最佳匹配）的预定义使用情况的过程。因此，技术特征L被对比文件隐含公开。 |
| **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>**《直接公开》** | [0073] ... the phase offset ... can change based on whether the mobile device 100 is being carried in a hand ... being held at the person's ear ... <br>[0098] ... the motion direction estimation module 666 can use any of the linear acceleration, ... to determine a likely use case. As described above, the motion direction estimation module 666 also can use non-movement related information to classify a current use case of the mobile device or person. For example, based on a certain tilt of the mobile device 100 ... or 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[0073]将“被持于耳边（being held at the person‘s ear）”列为一种使用情况。[0098]进一步说明，运动方向估计模块可以利用非运动相关信息（例如，是否发起呼叫）来分类使用情况，并可以确定移动装置正被持于耳边。将移动装置持于耳边进行通话即是“电话模式”的典型表现。因此，对比文件公开了“移动装置处于电话模式的使用情况”。技术特征M被直接公开。 |

| **技术特征R：** 及其中所述移动装置随着用户跑步被拿于所述用户的侧面的手中的使用情况。<br>**《隐含公开》** | [0073] The phase offset ... may also change based on a change in speed, gait or cadence (for example, from walking to jogging to running) Each of these scenarios also may be considered a particular use case. | 对比文件[0073]将跑步（running）列为一种基于步速/步态变化的使用情况。结合前文[0073]已公开的手持且随行走摆动（在侧面）的使用情况，本领域技术人员可以合理推断，当用户跑步时，移动装置同样可能被拿在手中并随手臂摆动在身体侧面。因此，“随着用户跑步被拿于用户的侧面的手中”这一使用情况被对比文件隐含公开。 |
| **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>**《直接公开》** | [0098] ... the motion direction estimation module 666 also can use non-movement related information to classify a current use case of the mobile device or person. For example, based on a certain tilt of the mobile device 100 ... or 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[0098]明确公开了运动方向估计模块可以使用非运动相关信息（例如，是否发起呼叫）来分类使用情况，并可以由此确定移动装置正被持于耳边（即电话模式）。这直接对应于“检测移动装置何时处于电话模式中”以及“识别使用情况还基于移动装置是否处于电话模式中”。因此，技术特征S被对比文件直接公开。 |
| **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>**《隐含公开》** | [0073] However, the phase offset between the vertical acceleration and forward/backward acceleration components can change based on where and how the mobile device 100 is being carried during motion; that is, based on a particular use case. For example, the phase offset ... can change based on whether the mobile device 100 is being carried in a hand ... being held at the person's ear ... or being carried in the person's pocket, purse, or pack. | 对比文件[0073]明确说明相位偏移（作为使用情况的特征）会基于移动装置被携带的“位置（where）”而变化，并举例了手中、耳边、口袋中等不同位置。这意味着，为了识别使用情况（例如，是手中模式还是口袋模式），需要确定移动装置相对于用户的位置。虽然对比文件没有明确描述一个独立的“确定位置”的步骤，但根据其整体教导，本领域技术人员能够理解，识别基于位置的使用情况，必然需要以某种方式（例如，通过分析加速度模式、倾角等传感器数据）来确定或推断移动装置相对于用户的大致位置。因此，技术特征T被对比文件隐含公开。 |
| **技术特征U：** 其进一步包含基于所述加速度数据或其它定向数据识别所述移动装置相对于所述坐标系统的定向。<br>**《直接公开》** | [0007] In some implementations, the method also includes identifying an orientation of the mobile device relative to the coordinate system based on the acceleration data or other orientation data.<br>[0065] The orientation determination module 664 determines the orientation direction O through an analysis of linear acceleration measurements, angular acceleration measurements, magnetic field measurements, or a combination of such measurements or sensor data, obtained by the sensors of the sensor suite 134. | 对比文件[0007]在概述中明确记载了方法可以包括基于加速度数据或其他定向数据识别移动装置相对于坐标系统的定向。[0065]进一步详细描述了定向确定模块664通过分析线性加速度、角加速度、磁场测量等传感器数据来确定定向方向O。因此，技术特征U被对比文件直接公开。 |

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[0098]公开了运动方向估计模块可以利用非运动相关信息（例如，基于陀螺仪或磁力计数据确定的特定倾角）来分类使用情况（例如，确定被持于耳边）。移动装置的“倾角”是其“定向”的一个方面。因此，这教导了识别使用情况可以基于定向数据（如倾角）。虽然未明确说“至少部分地基于定向”，但基于定向数据（倾角）来确定使用情况，实质上就是识别使用情况至少部分地基于定向。因此，技术特征V被对比文件隐含公开。 |
| **技术特征W：** 其中计算所述移动装置相对于所述坐标系统的所述经估计运动方向还至少部分地基于所述定向。<br>**《直接公开》** | [0007] In some such implementations, estimating the motion direction of the mobile device relative to the coordinate system also is based at least in part on the orientation. | 对比文件[0007]明确记载了“估计移动装置相对于坐标系统的运动方向也至少部分地基于该定向”。这直接公开了技术特征W。因此，技术特征W被对比文件直接公开。 |
