Abstract

一种在便携单元和通信系统之间传送信号的系统和方法。便携设备利用感应耦合与母机单元通信。母机单元还与诸如电话网络的更大的通信系统连接。在母机单元中使用了多个正交排列的转换器来提供更完整的磁场并防止在磁场中出现的互感盲区。使用短距离感应耦合最大限度地减小对电源的需求并限制了与其它源的干扰。感应耦合也可以用于给便携设备中的电池充电。

Description

短距离磁通信系统
本发明涉及短距离无线通信系统，尤其涉及利用感应耦合的系统。
在使用电话时，常时间将听筒握持在人的耳朵上可能很不方便。而且，当试图通话时，把持电话会防碍双手进行其它工作。特别是在驾车时使用蜂窝电话(正在迅速增加)会干扰使用者正常的驾驶操作。已有各种用于克服这些困难的技术。
免提型电话(speakerphone)使人可以一边在屋内走动一边用双手做事。然而，免提型电话的扬声器的声音会干扰使用者周围的其他人。由于相互间的干扰，不能同时使用放置在近处的两个以上的免提型电话。因为扬声器将通话内容播放给所有能听到的人，所以它们会泄露秘密。通常，使用者的讲话必须比正常情况下要响亮，以使传声器能正常接收使用者的声音。而且，因为使用者不常在传声器的近处且室内的声学效果差，所以传声器接收声音的质量经常不好。
头戴型电话(headset)是另一种解放电话用户双手的途径。通常，头戴型电话包含：一可调节的沿使用者头部伸展的吊带，用于定位头戴型电话；至少一个位于使用者耳部的耳机；以及，从头戴型电话伸出的传声器，它围绕着使用者的面部并定位于使用者嘴前。头戴型电话通过电线接在电话机上。头戴型电话的缺点是体积大且使用时有些麻烦。虽然在使用电话机时它们解放了双手，但由于连接线而限制了使用者的活动范围。
也开发了消除与电话机之间连接线的无线头戴型电话。无线头戴型电话采用了射频(RF)技术或红外技术，来在头戴型电话和与电话机相连的母机单元之间进行通信。与母机单元通信所需的通信电路和相当的电源增加了头戴型电话的体积和重量。使用者会对电话重量的增加感到厌烦。另一种方法是将头载型电话用电线与一发送单元相连，该发送单元挂在使用者的皮带上。但对于无线头戴型电话，电线就变得不方便了，而且会干扰使用者的其它动作。在邻近范围内使用多个头戴型电话时还需要有效的干扰抑制电路。
因此，要求一种能给使用者提供更方便和舒适的电话机无线通信系统。
本发明通过以下的特点来克服现有技术系统的这些缺点，其中的一个特点是，包括一个短距离、无线通信系统，在该系统中包括袖珍便携转发器和母机单元转发器。袖珍便携转发器利用磁感应与母机单元(也可以是便携的)互通信息。同样，母机单元也利用磁感应与便携转发器交换信息。信息可以是人的声音、数据、音乐或视频。使用磁感应场可减少电能消耗，从而带来更小的尺寸和更大的便利。
本发明的另一个特点是，母机单元可包括多个正交排列的用于产生多个磁场的转换器。多个磁场基本上消除了在母机单元和便携单元之间在一产生场的一定位置上出现的互感盲区。本发明的另一特点是，多个转换器可选择性地根据最强信号操作，以便减少电能损耗。
本发明的另一个特点是，头戴型电话包含袖珍转发器，转发器利用磁感应场与母机单元通信。在头戴型电话和母机单元之间传送的信息可以是声音和数据。本发明的另一个特点是，头戴型电话可以是外耳形的，其中的扬声器置入使用者耳朵，而没有跨在头部的吊带，且用于收发信号的转发器封装在沿使用者面颊摆放的短而直的传声器托杆上。本发明的另一个特点是，母机单元可以是使用者可携带的便携式电话机，用于进一步从无线通信系统发送信号给蜂窝电话网或无绳电话机单元。
本发明的另一个特点是，头戴型电话可以置入便携母机单元的支座内，以便对头戴型电话内的电池充电。本发明的另一个特点是，通过在母机单元和头戴型电话之间的磁互感应来给电池充电。
通过参照下述对本发明的详细说明、所附权利要求书和附图，将会进一步了解本发明的这些和其它目的、优点和特征，也将更清楚地理解本发明的实质。附图中：
图1是本发明的无线通信系统的示意图；
图2是图1的通信系统中作为母机单元的手持电话的示意图；
图3是图1的通信系统中作为便携设备使用的头戴型电话的示意图；
图4是该便携设备的转换器和电路的示意图；
图5是母机单元的转换器和电路的示意图；
图6是母机单元另一种转换器结构的示意图。
如图1所示，短距离磁通信系统1包括便携设备2和母机单元1，该系统连接到一长距离通信网14上。在母机单元1和便携设备2中分别含有短距离微型磁感应转发器11、12，它能同时发送和接收通信信号13。这些信号可以是声音、音频、数据或视频。通信网14可以是任何将这些信号经终端链路进行无线通信所需的网络，例如电话网、个人通信(PCS)网、专用移动无线(SMR)网、计算机系统或网络以及视频会议系统。母机单元1可以是通信网14中与其它设备进行无线通信所需的任何部分：例如，可以是手持电话、PCS手持机、SMR手持机、步话机、计算机或计算机外围设备、个人数字助理(PDA)或视频游戏控制机。便携设备2可以是与通信网络进行无线通信所需的任何部分：例如，可以是头戴型电话机或手持电话机、便携计算机或计算机外围设备、耳机、或视频输入设备。
如图2所示，母机单元1的一个实例是便携电话10，它具有多个数字按钮15和多个功能按钮16。可收回的天线17与蜂窝电话网或无绳电话母机通信。便携电话10的操作与通常的蜂窝或无绳电话手持机的操作相同。以通常的方式从电话网接收信号或将信号发送到电话网。便携电话10包括利用磁感应与头戴式话机20通信的转换器系统30，该头戴机20用作便携设备2以提供对便携电话10的输出和输入。便携电话10也可包括如常规手持电话中的受话器和收话器(未示出)，以便于使用者在头戴机20提供的常规操作方法和免提操作之间进行选择。
图3更完整地示出作为便携设备2的头戴机20。它包括容纳转换器40和处理电路的主体23。扬声器22与主体23中的电路相连。与扬声器22相邻的收话器21贴在使用者的耳朵上以固定该单元并使使用者听到扬声器的声音。传声器托杆24从主体23伸出几英寸，以把传声器25固定在托杆24的末端紧靠使用者嘴部的位置。或者，转换器40可以装在托杆24内。可充电电池51也装在头戴机20的主体23内以给头戴机提供电力。头戴机20的其它一些可选特征包括诸如用于人工启动不同模式的开关和按钮，例如可使用电容开关或按钮使头戴机20发送控制信号给便携电话10，以使传声器关闭。便携电话10可包括用于容置头戴机20的支座19。将头戴机放置在该支座内除使头戴机20和便携电话10合为一体以外，还具有许多功能。在该支座内可放置一开关来在头戴机20插入时终止无线通信或在头戴机20拔出时启动无线通信。该支座还可包括连接件以给头戴机20中的电池51充电。
虽然可以利用其它调制方法如频率或相位调制，但母机单元1和便携设备2利用对感应场的幅度调制进行通信。在使用过程中，在便携设备2和母机单元1之间的距离常常很短。由于距离很短，仅需感应场，很少或没有辐射出现。这节省了工作电源，可以减小充电电池51的尺寸和重量，从而可以减小便携电话2的尺寸和重量。此外，它还抑制了在小范围工作的系统之间的干扰。因此，可降低对便携设备2中干扰抑制电路的要求或不在便携设备2中设置干扰抑制电路。
图4示出便携设备2中的转换器系统。转换器40最好包括具有被线圈42围绕的铁氧体磁棒41的铁氧体磁棒转换器。转换器40的电线连接到具有发射元件28和接收元件29的转发器27。转发器27连接到便携设备26，它的特性取决于便携设备2的功能。在作为便携设备例子的头戴机20中，便携设备元件与扬声器22和传声器25相连。发送和接收是在不同频率下进行的，这容许全双工操作。或者，可使用单独的发送和接收转换器。
图5示出母机单元1的结构。转换器系统包括三个相互正交放置的铁氧体磁棒转换器，每个转换器包括铁氧体磁棒31、32、33和对应的线圈34、35、36。利用正交放置的转换器避免了在所产生的感应场中出现互感盲区。这三个转换器连接到多工元件60，以选择一个或更多的转换器，来发送和接收信号。可使用一电路来选择具有最强发送和接收信号的单个或多个转发器来降低设备的总电能消耗。发射元件61和接收元件62用于处理来自母机单元元件70和便携设备2的通信信号。如上所述，对于便携电话10来说，可排除常规的电话扬声器71和受话器72，以使便携电话10单独使用头戴机20来通过转换器系统和使用者通信。还可包括来选择扬声器71和传声器72与头戴机20之一的开关电路(未示出)。该开关电路可置于支座19中使得在拔出头戴机20时扬声器71和传声器72断开。
图6示出母机单元1的转换器系统的第二实施例。在图6的转换器30中，一个铁氧体磁棒转换器被置换为环路线圈转换器37。环路线圈转换器可置换任何或全部铁氧体磁棒转换器。环路线圈转换器37放置在剩余铁氧体磁棒转换器所处的平面上。这形成了一个厚度被减小的转换器系统。如图2所示，三个正交的转换器可放置在沿便携电话10侧面的角落中。或者，环路线圈可沿便携电话10的背面放置，以使把便携电话作得更薄。
此外，可采用发送系统给便携设备2的电池51充电。母机单元1包括与发送器61连接的电池充电信号产生器51。此产生器52产生经母机单元1的一个铁氧体磁棒转换器发往便携设备2的铁氧体磁棒转换器40的充电信号。由于在图2的电话实施例中，在支座19中的头戴机20和转换器40具有特定的取向，所以在便携电话10中只有一个转换器需要被激活来感应地发送充电信号。如图3所示，便携设备2中转发器40的电线连接到用于给电池51充电的电池充电器50上。
虽然在上面结合作为母机单元的外耳形头戴机20或蜂窝或无绳电话头戴机10，说明了本发明的通信系统，但它也易适合于其它类型的头戴机和一些应用。头戴机可以是跨头型、跨耳型或双耳型的。该系统可用作与常用桌面电话的无线连接。这样的系统可以上述方式与无绳手持机一起操作。由于在小范围内可使用几个这样的单元，所以相互间的干扰会成为较严重的问题。因此，可将该系统设计成在不同的频率下工作，并选择不易有明显干扰的发送和接收频率。同样地，用于语音数据输入、声音发送和电话功能的该系统也可与台式计算机或便携计算机一起工作。该系统还可以与其它类型的通信系统一起使用，如个人数字助理(PDA)、无绳电话、PCS和SMR蜂窝电话、双路(视频游戏)、双路半双工器(步话机，CB)或双路全双工器(电话)等。当母机单元是固定的，且使用者可能在相对于母机单元的某一位置上时，在母机单元内可使用很少的转换器而不会有互感盲区。也可使用其它的转换器系统来产生感应场。具体说，采用多个单独的转换器而不是采用一个转换器来在不同频率下发送和接收。
由于上面已经对本发明的一个实施例进行了说明，所以本领域技术人员容易对之进行各种替换、修改和改进。然而，这种替换、修改和改进应在本发明的精神和范围之内。因此，前述说明是示范性的而不是限制性的。本发明仅受限于所附权利要求和其等效物中的规定。
