### 特征比对表格
| 技术特征描述及公开性判断结果 | 对比文件原文引用 | 公开性论述 |
| **技术特征A**《直接公开》 | [p0015] “...a mobile device, such as , for example, a mobile telephone, which uses sensor components which are typically conventionally already found in such mobile devices, such as cameras and microphones, to perform a determination as to the present situation of the device.” | 该技术特征要求通过移动装置的一个或多个传感器动态检测其相对于邻近物理对象的放置。对比文件[p0015]明确公开了移动设备使用传感器组件(如相机、麦克风)来确定其当前情境(situation),这等同于检测其放置。对比文件全文(如[p0054]-[p0057], [p0061]-[p0067])详细描述了利用相机、屏幕、麦克风、扬声器等传感器检测设备是否在口袋中、在用户手中、在桌面上朝上或朝下等具体放置。因此,本领域技术人员能毫无疑义地得出对比文件公开了“经由移动装置的一个或多个传感器动态检测移动装置的相对于邻近物理对象的放置”这一技术方案。 |
| **技术特征B**《未公开》 | [p0015] “...the ability to distinguish between situations allows for the mobile device behaviour to be adapted in dependence on the discrimination. For example, the mobile device ringer volume may be changed, or the magnitude or frequency of vibration of the device vibrator altered.” | 该技术特征要求“根据所述移动装置的所述放置执行所述移动装置的扬声器均衡”。根据目标专利说明书[0021]、[0024]段,扬声器均衡(speaker equalization)是指根据所确定的放置,从预定配置中选择并应用均衡配置,以改变扬声器输出的频率。对比文件虽然公开了根据检测到的情境(放置)来调整设备行为(adapt its behaviour),但其调整的行为明确列举为:改变铃声音量、改变振动器的振动幅度或频率、控制屏幕亮度([p0015], [p0055]-[p0057])。在整个对比文件中,从未提及对“扬声器均衡”或“扬声器输出的频率范围”进行调整。其提及的“speaker”仅用于发出测试音以辅助情境检测([p0068]-[p0076]),或用于常规通话、音乐播放([p0007]),而非为了补偿因放置导致的声学性能变化而调整其频率响应。因此,对比文件未公开“执行扬声器均衡”这一技术特征。 |
| **技术特征C**《直接公开》 | [p0015] “Preferably, the possible situations comprise at least two or more selected from the group comprising: in an enclosed space, in a user's hand, face up on a surface, face down on a surface.” <br> [p0055] “A third situation in which the device may find itself is that of Figure 4a, i.e. face up on a surface 14... In the case of Figure 4b where the device finds itself face down on the surface...” | 该技术特征限定了“移动装置以扬声器面向下放置在表面上,其中所述扬声器至少部分地被阻挡”。对比文件明确将“face down on a surface”(表面上面向下)列为设备可能的情境之一([p0015], [p0055])。当设备面朝下放置时,其正面(通常包含扬声器)朝向表面,扬声器必然被表面至少部分阻挡。这符合本领域技术人员的普遍理解。因此,该放置情形被对比文件直接公开。 |
| **技术特征D**《直接公开》 | [p0015] “Preferably, the possible situations comprise at least two or more selected from the group comprising: in an enclosed space, in a user's hand, face up on a surface, face down on a surface.” <br> [p0055] “A third situation in which the device may find itself is that of Figure 4a, i.e. face up on a surface 14...” | 该技术特征限定了“移动装置以扬声器面向上放置在表面上,其中所述扬声器不受阻挡”。对比文件明确将“face up on a surface”(表面上面向上)列为设备可能的情境之一([p0015], [p0055])。当设备面朝上放置时,其正面(通常包含扬声器)朝上,扬声器不被表面阻挡。这符合本领域技术人员的普遍理解。因此,该放置情形被对比文件直接公开。 |
| **技术特征E**《直接公开》 | [p0015] “Preferably, the possible situations comprise at least two or more selected from the group comprising: in an enclosed space, in a user's hand, face up on a surface, face down on a surface.” <br> [p0055] “When the device finds itself in the second situation shown in Figure 3, wherein the device is in its user's hand...” | 该技术特征限定了“移动装置由用户保持,其中所述扬声器不受阻挡”。对比文件明确将“in a user's hand”(在用户手中)列为设备可能的情境之一([p0015], [p0055])。当设备被用户手持时,扬声器可能不受阻挡(取决于握持方式),这属于该情境下的一种常见情况。因此,该放置情形被对比文件直接公开。 |
| **技术特征F**《直接公开》 | [p0015] “Preferably, the possible situations comprise at least two or more selected from the group comprising: in an enclosed space, in a user's hand, face up on a surface, face down on a surface.” <br> [p0052] “Figure 2 illustrates how a mobile communications device 10 can commonly be found in an enclosed space, such as a user's pocket.” | 该技术特征限定了“移动装置保持在隐蔽位置中,其中所述扬声器至少部分地被阻挡”。对比文件明确将“in an enclosed space”(在封闭空间内,如用户口袋)列为设备可能的情境之一([p0015], [p0052])。当设备在口袋等隐蔽位置时,扬声器必然被周围材料至少部分阻挡。因此,该放置情形被对比文件直接公开。 |
| **技术特征G**《直接公开》 | [p0015] “Preferably, the possible situations comprise at least two or more selected from the group comprising: in an enclosed space, in a user's hand, face up on a surface, face down on a surface.” | 该技术特征为“各项的各种组合”,即特征C-F中任意两种或多种放置情况的组合。对比文件[p0015]将“in an enclosed space, in a user's hand, face up on a surface, face down on a surface”这四种情境作为一个优选组合并列公开。这意味着这四种情境中的任意两种或多种的组合都已被隐含涵盖在本领域技术人员对对比文件公开内容的常规理解中。因此,该技术特征被对比文件直接公开。 |
| **技术特征H**《未公开》 | 无相应内容。 | 该技术特征要求“执行扬声器均衡进一步包括:至少部分基于所述移动装置的所述放置而识别预定扬声器均衡配置”。如对特征B的论述,对比文件未公开任何与“扬声器均衡配置”相关的内容。其根据情境调整的是铃声、振动、屏幕等,而非用于扬声器频率补偿的预定配置。因此,该技术特征未被对比文件公开。 |
| **技术特征I**《未公开》 | 无相应内容。 | 该技术特征要求“根据所述预定扬声器均衡配置调整所述移动装置的所述扬声器输出的频率范围”。如对特征B和H的论述,对比文件完全未涉及调整扬声器输出的频率范围。因此,该技术特征未被对比文件公开。 |
| **技术特征J**《隐含公开》 | [p0055] “In the case of Figure 4b where the device finds itself face down on the surface...”;[p0052] “Figure 2 illustrates how a mobile communications device 10 can commonly be found in an enclosed space, such as a user's pocket.” | 该技术特征限定“所述移动装置的所述放置至少部分地阻挡所述扬声器”。对比文件公开了设备“面朝下在表面上”([p0055])和“在封闭空间内(如口袋)”([p0052])这两种放置。本领域技术人员结合移动设备的常规设计(扬声器通常位于设备正面或侧面)可以合理推断,在这两种放置情形下,扬声器非常有可能被桌面或口袋布料至少部分阻挡。因此,该技术特征被对比文件隐含公开。 |
| **技术特征K**《隐含公开》 | [p0055] “A third situation in which the device may find itself is that of Figure 4a, i.e. face up on a surface 14...”;[p0055] “When the device finds itself in the second situation shown in Figure 3, wherein the device is in its user's hand...” | 该技术特征限定“所述移动装置的所述放置移除对所述扬声器的阻挡”。对比文件公开了设备“面朝上在表面上”([p0055])和“在用户手中”([p0055])这两种放置。本领域技术人员结合移动设备的常规设计可以合理推断,在“面朝上”放置时,扬声器通常不被阻挡;在“用户手中”放置时,存在扬声器不被用户手部阻挡的握持方式。因此,该技术特征被对比文件隐含公开。 |
| **技术特征L**《直接公开》 | [p0015] “...uses sensor components which are typically conventionally already found in such mobile devices, such as cameras and microphones, to perform a determination as to the present situation of the device.” <br> [p0077] “In further embodiments to be described, however, further discrimination between situations becomes possible by combining the sensors, for example to use two or more sensor media, such as, for example, sound and light.” <br> [p0083] “...a vibrator and accelerometer sensor combination is used...” | 该技术特征限定了动态检测放置所基于的数据来源,包括相机、环境光传感器、加速度计等。对比文件[p0015]明确公开使用相机(camera)、麦克风(microphone,作为声音传感器)来确定设备情境。[p0077]提到了结合使用声音和光传感器。[p0083]明确公开了使用加速度计(accelerometer)与振动器组合来辅助情境判断。虽然对比文件未明确列举磁力计、陀螺仪等具体传感器,但其核心思想是利用设备已有的多种传感器(包括但不限于相机、麦克风、加速度计)进行情境检测,这直接公开了技术特征L的实质内容。因此,本领域技术人员能毫无疑义地得出对比文件公开了基于来自相机、加速度计等传感器的数据推断放置的技术方案。 |
