Description

电感外围保持设备
背景
计算设备可采用外围设备来帮助用户与该计算设备进行交互。该情况的一个示例是可被用于帮助用户与计算设备的触摸屏和其他功能进行交互的诸如指示笔之类的替换输入设备。例如，用户可利用指示笔在触摸屏的表面上绘制以便做注释、笔记、以及其他标记。
然而，在许多不同的方面用于存储指示笔的常规技术可能是有问题的。例如，使用通过摩擦力或通过双推(push-push)式机制来存储并保持指示笔的内部槽可能造成在设备内部需要额外空间和部件的问题。这也可导致对于移动配置而言是不理想的在设备复杂性、设备的整体大小方面的增加，并且可能因此妨碍了用户对该设备的体验。
在另一示例中，挂绳和笔帽的使用可在某种程度上用作不受控附属物，并因此勾住其他物体，笔帽往往因可被使用的保持力的限制而让笔落出，等等。因此，由于这些复杂性，用户可能选择放弃使用由外围设备支持的此附加功能。

详细描述
概览
计算设备可以使用各种各样外围设备以支持不同类型的与设备的用户交互。这可包括被配置成除了计算设备之外被使用的输入设备，其示例是指示笔。然而，被用于存储外围设备的传统技术往往麻烦并且妨碍了用户与外围设备和计算设备两者的交互。
描述了电感外围保持设备技术。在一个或多个实现中，外围保持设备被配置成使用插头被固定到计算设备或其他设备(例如，计算设备的诸如监视器、键盘等外围设备)，该插头被配置成啮合例如USB端口或其它端口的通信端口。外围保持设备还包括连接到插头以保持诸如指示笔之类的外围设备的外围固定部分。
外围固定部分例如可包括被形成为柔性环的电感元件，该电感元件被配置成至少部分地围绕外围设备并在外围设备和计算设备之间形成通信耦合，诸如以对外围设备充电、传输数据等。以此方式，使用该环的充电效率可相对于常规技术增加，并且环的柔性可在不使用时被用于限制该环对用户的干扰，例如可以展平。另外，此柔性可用作控制向环的功率输出的基础，并从而提高设备的效率，如以下进一步描述的。
还描述了可被用于支持旋转不变的电感的电感元件。电感元件例如可被定形成模仿杠铃，使得电感元件的通量线具有模仿甜甜圈的形状。以此方式，电感元件可被用于支持设备的电感，而无需将设备旋转至特定定向，诸如用于指示笔、外围设备(例如键盘)的柔性铰链或计算设备等等的使用。这些特征的进一步讨论可结合图8和9被找到。
在以下讨论中，首先描述了可采用本文描述的技术的示例环境。同样描述了可在该示例环境以及其他环境中执行的示例机制。因此，对各示例机制的使用不限于该示例环境，并且该示例环境不限于对示例机制的使用。
示例环境
图1是可在操作上采用本文描述的技术的一示例实现中的环境100的图示。示例环境100包括具有至少部分以硬件实现的多个计算组件104的计算设备102。这些计算组件104所示出的示例包括处理系统106和被例示为存储器108的计算机可读存储介质、外围保持设备110、电池112、以及被置于外壳116内和/或被固定到外壳116的显示设备114。
计算设备102可以各种各样的方式被配置。例如，计算设备可被配置成能够通过网络进行通信的计算机，诸如台式计算机、移动站、娱乐设备、通信地耦合至显示设备的机顶盒、无线电话、游戏控制台等等。因此，计算设备102的范围可以是从具有充足存储器和处理器资源的全资源设备(例如，个人计算机、游戏控制台)到具有有限存储器和/或处理资源的低资源设备(例如，常规机顶盒、手持式游戏控制台)。
计算设备102被进一步例示为包括操作系统118。操作系统118被配置来将计算设备102的底层功能抽象给可在计算设备102上执行的应用120。例如，操作系统118可抽象计算设备102的计算组件104，以使得可在不知晓这个底层功能“如何”实现的情况下编写应用120。例如，应用120可向操作系统118提供要被呈现并由显示设备114显示的数据，而无需理解该呈现如何被执行，可接收使用显示设备114的触摸屏功能检测到的输入，等等。操作系统118也可表示各种其他功能，诸如管理计算设备102的用户可导航的文件系统和用户界面。
计算设备102可支持各种各样不同的交互。例如，计算设备102可包括可被用户操纵来与设备进行交互的一个或多个硬件设备，其可能包括外围设备112(例如，诸如鼠标、指示笔之类的光标控制设备)、使用柔性铰链126通信地并物理地耦合到计算设备102的键盘124，等等。
诸如指示笔之类的外围设备122在一些情况下可能被用户遗失，因为设备没有物理地附连到计算设备102，特别是在计算设备102的手持(即，移动)配置中。然而，用于将指示笔固定到计算设备102的传统技术可在外壳116内消耗大量空间(例如，通过用于摩擦力或通过双推式机制存储并保持指示笔的内部槽)，干扰与设备的用户交互(例如，挂绳)，等等。因此，外围保持设备110可被配置成将外围设备122以不干扰用户与计算设备102的交互的方式固定到外壳116。
此外，外围保持设备110还可被配置成支持与计算设备的通信端口128的通信耦合，诸如传输功率以对外围设备122充电，在外围设备122与计算设备102之间传递数据，等等。例如，现在一般惯例是使用指示笔在膝上型计算机和平板设备的启用触摸的显示器上绘制。在一些实例中，指示笔可被配置成消耗功率以支持此交互。
在一个这样的实例中，有源指示笔被配置成通过发射由显示设备114的触摸屏功能接收的信号来提高无源指示笔的可检测性，以提高指示笔的尖端的空间分辨率。甚至可在尖端悬停在显示设备114的表面上方时定位该尖端。有源指示笔还可消耗功率以支持通信、按钮激活特征等等。可能消耗功率的其他特征包括指示笔角度的检测和用于调整墨水厚度的笔尖的旋转，笔功能或通知的触觉或声音反馈、支持用作用于会议室协作的激光指示器、包括用于状态和通知的文本显示、传递设备状态、电子邮件、和其他始终通信的通知、以及LED指示器，支持音频记录和数据存储等。该功率可由被包括为外围设备的一部分的可重新充电的存储器提供，例如电池或超级电容器。
用于向可重新充电的存储器提供功率的常规技术可能具有各种缺点。例如，被指示笔使用的微型USB连接器通常涉及将连接器放置在与尖端相对的指示笔的端部上。通过将指示笔插入USB端口来对该指示笔充电还需要具有附加的USB电缆或着直接插入平板设备或膝上型计算机。这可能涉及指示笔拆卸、跨产品线的公共USB端口、并且由于其在充电时是悬臂的因此具有产品损坏的风险。
另一种常规技术涉及向指示笔的外部添加导电充电点，以将其直接连接到提供功率的设备(例如，计算设备)上的充电点。然而，此直接通电充电技术可能干扰工业设计，使接触点暴露于磨损和损坏，并可能在其对准以便以可预测的方式将指示笔接触点连接到电源方面受限。
因此，外围保持设备110可被配置成支持无线电感充电。例如，外围设备122可包括接收线圈，当接收线圈被耦合到外围保持设备110的外部的、供电的、初级充电线圈时，在该接收线圈内形成变压器的次级。此气隙变压器将功率发送到外围设备122，并从而支持外围设备122、外围保持设备110、以及计算设备102之间的通信耦合，该气隙变压器也可被用于在所述设备之间传递数据。
虽然外围保持设备110被例示为连接到计算设备102的通信端口128，但是外围保持设备110可被耦合到各种其他设备，诸如外部电池设备(例如，用于移动充电)、外部充电设备(例如，插入墙插座)、输入设备124上的通信端口128、如图4所示的监视器等等。
图2描绘了显示图1的外围保持设备110的示例的不同视图的示例实现200。此示例实现包括外围保持设备110的示例的俯视图202、透视图204、正视图206以及侧视图208。外围保持设备110包括被配置为被固定到设备的通信端口128的插头210。在此示例中的插头210被例示为遵从A类通用串行总线(USB)形成，但应当容易明白其他配置也可被构想，诸如遵从其他类型的USB端口(例如，B类、迷你AB类、迷你B类、微AB类、微B类、C类)、通信端口等等。还可构想其他示例，诸如无需插头的使用(例如永久地安装到计算设备)。
外围保持设备110还包括外围固定部分212，该外围固定部分212被连接到插头并被配置成可移除地啮合外围设备，在此示例中，外围固定部分212使用柔性环214来执行。柔性环214例如可被配置成屈曲并延展以将诸如指示笔之类的外围设备保持在柔性环214的内部。
如图3的示例实现300所示，例如外围保持设备110可被固定到以虚线示出的通信端口128。图1的外围设备122的示例被例示为被保持在柔性环214内并因此被固定到计算设备102的指示笔302。
在例示的示例中，柔性环214采取通过使用诸如织物、橡胶或弹性材料之类的柔性材料来固定的外围设备的互补的形状。还构想了其他示例，包括其中外围保持设备110使用不是柔性的技术的示例，例如被铸模成适应要被保持的外围设备122的外表面。
柔性环214还可被配置成提供用于固定外围设备的偏置力。例如，被形成为柔性和可延展的环(例如，弹性)可将外围设备朝向外壳116偏置，并且由此抵靠外壳116来保持外围设备。还构想了其他示例。
用柔性材料形成的柔性环214还可支持各种其他功能。例如，柔性环214可被配置成“展平”，如图11所示。计算设备102例如可被放置在表面上，当指示笔302未被设备保持时，这使得柔性环抵靠该表面展平。另外，这可允许指示笔302“向上旋转”远离表面，使得计算设备102可抵靠该表面展平。以此方式，外围保持设备110不干扰用户与计算设备102的交互。
图4描绘了另一示例实现400，其中图3的外围保持设备110被用于将指示笔302固定到独立显示设备。在此示例中，外围保持设备110被固定到独立显示设备402的通信端口。以此方式，当指示笔302不使用时，指示笔302可以“不挡道”的方式被固定。此外，指示笔302还可通过使用形成为外围保持设备110的一部分的电感元件来充电，其进一步的讨论可在下文中被找到并被显示在相应的附图中。
图5描绘了显示图3的外围保持设备110的电感元件502的示例性实现500。在此示例中的电感元件502被配置成既是柔性的又是可延展的。在此示例中，这由包括具有大致杠铃形状的椭圆形穿孔504来执行，其中穿孔504的端部具有比穿孔504的中间部分更大的宽度。还构想了其他穿孔形状。
穿孔504还以相对于纵向轴线506大致成四十五度的角度被布置，其被配置成形成弯曲以呈现如图6所示的圆柱形形状并支持沿x和y方向的延展。另外，穿孔504具有相对于轴线506的彼此交替布置的角度。
电感元件502还包括被配置成承载电流以形成电感连接的迹线508。通过在具有正弦迹线图案和椭圆形穿孔504的基板(例如，聚酰亚胺基板)上将电感元件502实现为初级线圈，电感元件502变得既柔性又可延展，以允许柔性环在不使用时折叠，并在诸如指示笔302之类的外围设备122的插入和移除期间抵抗损坏。
图6描绘了一示例实现600，其中图5的电感元件502被弯曲以形成柔性环502。如所例示的，电感元件502的穿孔504允许弯曲以形成环。穿孔504还可允许延展，以致提供用于将外围设备122保持在柔性环216内的弹性力，如前所述。迹线508被配置成在柔性环214的内部形成电感电场，从而形成电感通信耦合。
图7描绘了一示例实现700，其中图6的电感元件502被安装成图2的外围保持设备110的一部分。在此示例中，电感元件502(例如，初级线圈)被配置成由织物702包围的柔性环。电感元件502作为外围固定部分212的一部分被通信地耦合到插头210，并因此可从如前所述的设备的通信端口128接收电。
常规上，用于附件充电的气隙变压器的初级线圈被展平地构造成“充电板”。然而，将初级线圈围裹在次级线圈周围增加了功率从充电器传输到附件的效率(例如，超过百分之七十七)。这种原型(图1)的测试已经产生了高达77％的效率，并且表明了在大约一小时内对160mA的锂质可重新充电的指示笔进行完全充电和在大约半小时内对超级电容器单元进行完全充电是可行的。
图8描绘了由图1的外围设备122使用次级线圈以形成设备之间的电感通信耦合的示例实现800常规的气隙变压器的次级线圈通常为三厘米乘四厘米以及更大，使得它们难以放置在诸如指示笔302之类的外围设备122中。
因此，在此示例中的电感线圈802由单个含铁元件形成，在此示例中的该单个含铁元件是具有中间部分804的单个整体件，该中间部分具有围绕轴线806的直径，该直径小于沿该轴线806的单个含铁元件的相对端部808、810的直径。
线圈812围裹中间部分804，使得线圈812和单个含铁元件形成围绕轴线基本上旋转不变的电感线圈802。电感线圈802可包括穿过纵向接入点的开放隧道(例如，类似于管道)，其可被用于允许电线穿过该隧道以支持从指示笔的一端到另一端的通信。相对端部808、810的直径允许含铁材料延伸到指示笔302的外壳的边缘，并且圆柱形形状通过形成如图所示的模仿甜甜圈的形状的通量线814来使耦合旋转不变。此次级线圈组件可被做成足够小并足够密集以便良好适配在指示笔302中，同时传输足够的功率以便在任何旋转位置对内部电池进行充电。
初级与次级线圈之间的电感耦合对各线圈之间的距离敏感。线圈越小，此耦合损耗发生地越快。此外，通常可以不限制指示笔302的纵向旋转位置的方式来存储该指示笔。因此，通过使用如图8所示的模仿哑铃的形状，在此实例中作为次级线圈来操作的电感线圈802可在使距外围保持设备110的初级线圈的距离最小化的同时在任何纵向旋转角度上具有良好的耦合虽然在此示例中被描述为次级线圈，但是电感线圈802也可用作如下文进一步描述的初级线圈。
图9描绘了一示例实现900，其中图8的电感线圈被配置成作为气隙变压器布置中的初级线圈来操作。在该示例中，输入设备124的连接部分902被示为配置成提供输入设备124与计算设备102之间的通信和物理连接。所例示出的连接部分902具有被配置为被容纳在计算设备102的外壳中的通道中的高度和横截面，但这一布置也可反转而不背离其精神和范围。
连接部分902通过使用柔性铰链126而柔性地连接到包括键的输入设备104的一部分。因而，在连接部分202物理上连接到计算设备时，连接部分902与柔性铰链126的组合支持输入设备124相对于计算设备102的移动，这类似于书脊。
在此示例中的柔性铰链126包括具有多个电感线圈906、908、910的中脊904，所述电感线圈被配置成类似于图8的电感线圈902，但在此实例中作为气隙变压器的初级线圈来操作。因此，在此示例中，为了在输入设备124(并因此在图1的计算设备102)到图3的指示笔302或其他外围设备122之间形成通信耦合，用户可将指示笔302抵靠柔性铰链或使用指示笔302的笔夹将其固定于柔性铰链以便引起电感耦合。如前所述，这可被用于对指示笔进行充电、传送数据(例如，用于认证外围设备122)等等。此外，通量流线也可支持旋转不变的形状，使得柔性铰链126可移动但仍然支持通信耦合。
图10描绘了一示例实现1000，其中功率模式被用于控制提供给外围保持设备110的电感元件502的功率量。该示例实现使用第一和第二阶段1002、1004来示出。充电模块1006在各个阶段都被例示出，该充电模块表示控制由外围保持设备110提供给电感元件502的功率量的功能。充电模块1006例如可被合并作为外围保持设备110本身的一部分、外围保持设备110所附连的设备(例如，计算设备102)等等。
在第一阶段1002，充电模块1006检测到柔性环214和对应的电感元件502被布置为环，诸如笔的插入。这可通过由充电模块1006测量电感元件502的电感来确定。笔内的含铁次级接收线圈导致电感元件502的电感的显著增加。因此，充电模块1006可确定电感元件502被配置成支持通信耦合，并可以提供足以对外围设备122进行充电的功率水平，例如功率模式1008。
然而，在第二阶段1004充电模块1006检测到柔性环214和对应的电感元件502已经折叠。这可由充电模块1006通过检测到电感元件502呈现低电感来检测。例如，当彼此紧密设置时(诸如当柔性环214折叠或展平时)，充电模块1006的相对侧可能导致短路。
因此，充电模块1006可检测到柔性环214和对应的折叠或短路状态，并进入降低功率模式1010，该降低功率模式比处于充电功率模式1008时向电感元件502提供更少功率，例如，可完全停止提供功率、周期性地提供功率以确定电感元件的电感，并因此确定是否进入充电功率模式1008等等。以此方式，充电模块1006可确定外围保持设备110是否被配置成执行电感并相应地作出反应，诸如以在未准备好时节省功率、传送数据等。此技术的进一步讨论可结合图12被找到。
图11描绘了可由外围保持设备110用作气隙变压器的初级线圈的电路1100的示例实现。如之前的，初级线圈可被用于传输功率以对外围设备122进行充电、传输数据等等。
示例过程
以下讨论描述了可利用先前描述的系统和设备来实现的电感外围保持设备技术。可以硬件、固件或软件或其组合来实现每一个过程的各方面。过程被示为指定由一个或多个设备执行的操作的一组框，不一定仅限于所示出的用于由相应的框执行操作的顺序。在以下讨论的各部分中，将参考以上所描述的各附图。
结合图1-11的各示例描述的功能、特征和概念可被用于此处所描述的规程的上下文中。此外，结合以下不同规程的功能、特征和概念可在不同规程中互换并且不限于单个规程的上下文。此外，与此处的不同代表性规程以及相应附图相关联的框可以不同方式被一起应用和/或组合。此外，结合此处的不同示例环境、设备、组件和规程所描述的单个功能、特征和概念可以任何适当的组合使用且不限于所枚举的示例所代表的特定组合。
图12是描绘了一示例实现中的过程1200，其中基于柔性环的电感的检测的确定来利用功率模式。存在三种电感情形，其可基于对电感和/或电流的检测来被检测并被利用。存在未插入外围设备的情形(例如，其具有低电感)、插入外围设备的情形(例如，其具有十倍于未插入设备时电感的电感)、以及电感元件不与柔性元件对准，而是另一具有最低电感的金属物品与柔性元件对准的情形。因此，阈值可被用于在这些情形之间进行区分，其示例被如下描述。
检测被配置成经由电感将功率传输到外围设备的柔性元件的电感(框1202)。充电模块1006例如可测量电感以便确定电感元件502是否正在经历短路。
在判定框1204，电感是否高于外围设备在环内阈值的确定被作出(判定框1204)。如果是(判定框1204为“是”)，则响应于所检测的电感高于阈值的确定，其中向柔性元件提供第一功率量的第一功率模式被使用(框1206)。例如阈值可被设置以指示电感元件是否正在经历短路，阈值可被设置为在柔性元件环214(例如，柔性环214和对应的电感元件502)的期望形状处检测到的电感量。如果是，则充电模块1008可提供足以传输数据、对外围设备122进行充电等等的功率量。
如果否(判定框1204为“否”)，则电感是否高于折叠阈值的确定被作出(判定框1208)。如果是(判定框1208为“是”)，则响应于所检测的电感低于阈值的确定，其中向柔性元件提供少于第一功率量的第二功率量的第二功率模式被使用(框1210)。此阈值可与先前的阈值相同或不同，例如，可被设置成使得低于该阈值的电感水平指示短路、被设置成在柔性元件(例如，柔性环214和对应的电感元件502)的展平/折叠形状处检测到的电感水平等等。
如果电感不高于折叠阈值(判定框1208为“否”)，则柔性元件被短路的确定被作出(框1212)。短路可通过电感被检测并也可通过检测高于阈值的过大电流汲取被检测。因此，第二功率水平可被采用，例如用于“关断”电感元件502的功率、以预定时间间隔周期性地检查电感、提供可用于进行检测的最小电流水平等等。定时简档也可被合并(例如，开10毫秒、关两秒)以提高功率节省。还构想了各种其他示例而不背离其精神和范围。
