Description

便携式信息终端、可移动记忆设备及具有这两者的系统
相关申请的交叉引用
本申请主张申请日为2005年4月29日的美国第60/675,849号临时专利申请的优先权,其整个内容通过引用而结合于此。
技术领域
本发明涉及一种可安装至购物手推车的便携式信息终端以及可于其上使用的可移动记忆设备,特别地,涉及一种设有用来收容便携式记忆设备的开口的便携式信息终端,该开口被门保护,并且涉及一种用来在插入开口时开启门的便携式记忆设备。
背景技术
购物手推车多年来在形式上都没有本质的变化。不过,近来随着便宜的、功耗小的小型计算机的供应,已经尝试在购物车中添加小型计算机来帮助使用者购物。举例来说,将条形码阅读器添加到购物车上,让使用者能够进行价格核对和/或自行结账。Gupta的美国专利5,361,871就揭示了这样一个系统,且该专利的内容在此一并纳入参考。然而,Gupta的设备看起来似乎会干扰固有的手推车嵌套(nesting),并且需要与手推车的底部电性连接以充电,这有可能在手推车通过商店走廊和/或商店停车场路边时被损坏。相信这样的系统,例如在Gupta中所揭露的不会被广泛采用。
可以夹在购物车把手上或者可拆卸的放置在购物车把手上的相关购物辅助设备也是众所周知的。然而,使用者在使用这些设备前必须要从架子或是其他存储位置取出并放置在购物车的车把手上。当购物者到达结账线时,商店工作人员必须将设备从购物车上拿下来和/或放回充电站,或是依靠顾客执行这些行为。相信这些不方便之处已经妨碍这样的设备被广泛采用。
因此,希望提供一种不具有上述缺陷,并且易于使用和维护的电子购物辅助设备。
发明内容
本发明是针对这些问题和其它的提出的,本发明的第一个特征就是,一种系统包括可安装至购物车的便携式信息终端用来在购物车在商店内移动且有外部记忆设备连接至所述便携式信息终端时提供产品与广告信息,所述外部记忆设备包括记忆本体;设于记忆本体内的存储数据的非易失性记忆体;以及自本体延伸以允许处理器访问所述存储的数据的第一电连接器;所述便携式终端包括:设有显示屏的终端本体;设于所述终端本体用来使所述显示屏显示产品信息与广告的处理器;以及设于所述本体内且与所述第一电连接器互补以将外部记忆设备连接至所述处理器的第二电连接器;所述终端本体包括提供自所述终端本体的外部通向所述第二电连接器的通路的通道;以及至少一个凹陷于所述通道的门,其可通过插入所述通道的所述外部记忆设备来从阻挡所述通道的第一位置移动至第二位置。
本发明的另一方面包括一种可安装至购物车以在购物车在商店内移动时提供产品与广告信息的便携式信息终端,所述终端包括:设有显示屏的本体;设于所述本体内用来使所述显示屏显示产品信息与广告的处理器;设于所述本体内以将外部记忆设备连接至所述处理器的电连接器;所述本体包括提供自所述本体的外部通向所述电连接器的通路的通道;以及至少一个凹陷于所述通道的门,其可通过插入所述通道的所述外部记忆设备在阻挡所述通道的第一位置和第二位置之间移动。
本发明的另一特征包括一种可用于包括有可安装至购物车上的信息终端的系统的外部记忆设备,所述信息终端可在购物车于商店内移动且有外部记忆设备可连接至所述便携式信息终端时提供产品与广告信息,所述外部记忆设备包括:记忆本体;设于记忆本体内的存储数据的非易失性记忆体;自本体延伸以允许处理器访问所述存储的数据的第一电连接器;以及自所述记忆本体凸伸且邻近于所述第一电连接器的凸伸件。

具体实施方式
现在参考图示,其中图示仅仅是为了阐明本发明的最佳实施例,而不是为了将发明限于图示本身,图1所示的以购物车把手10的形式的信息终端包括自中央本体14的延伸的第一和第二手柄12。中央本体14包括显示屏16,最好是触摸屏,以及用于容纳电子模块、图17所示的电池15、电路板、条形码阅读器17以及其他在这里描述的功能元件的内部空腔。本体14包括与手柄12一体形成的第一部或是前部18以及后部20。后部20可以通过螺钉或是搭扣可移动地固定至前部18,也可以永久地固定至前部18,比如通过合适的粘贴剂。当后部20是可移动地固定到前部18时,需要提供一个合适的垫圈以在保证水密性的密封的同时允许后部20呼吸并且将本体14的空腔内的冷凝减到最小。
虽然图1所示的信息终端包括附加的握持部12,也可能形成不包括握持部12的信息终端并且改为提供用来将信息终端10连接至现有购物车把手的安装硬件(未图示)。图37所示为不包括握持部12的信息终端10’。
手柄12包括握持部21以及与本体14结合的加强部22,以增加车把手10的强度,并降低手柄12与本体14的结合部在车把手10被推拉或是本体14受到向下的压力时受到损坏的可能性。握持部21包括覆盖了其大部分长度的大约3英尺或8厘米的圆周(或者是外围,当握持部的不具有圆形的截面时),以使用者在握持的时候感到舒适。加强部22向外展开并且具有自握持部21的外围向本体14的侧壁逐渐增加的较大的圆周或外围。如图1和图2所示,向外展开的加强部22围住了握持部21的各个面,因而握持部21朝着本体14延伸的横截面会穿过而不会与加强部22的最大的圆周或外围交叉。
本体以及内部的组件可以使用于一较宽的温度范围,例如-45℃至70℃,因而设备在非常冷的冬天或是阳光直射的夏天都可以存放在户外,并且可以抵抗潮湿或是其它购物车把手可能遭受到的冲击。手柄和本体最好是用合适的热塑材料构成。
电池15可以再充电并且在再充电之前可以支持电子模块工作大约16个小时。
本体14包括用来收容条形码阅读器17的开口24以及提供接入到内部I/O端口或连接器30的通道28,例如,如图8所示,本发明一较佳实施例包括USB端口。收容在本体14内的硬件将执行多种功能并且在显示屏上提供多种显示,但功能和显示并不构成目前揭露的一部分。
本体14内的硬件可以通过插入到端口30的启动装置启动。在本实施例中,启动装置包括具有与端口30相适应的USB接口的固态记忆设备32,可替换地,电子模块可以由条形码阅读器17扫描经授权使用者的条形码来启动,例如消费者忠诚卡(customer loyalty card)上的条形码。当使用记忆设备32时,记忆设备32上的使用者信息能够可选择性地供本体14中的处理器读取和/或传送到与电子的购物车把手10进行无线通讯的中央服务器上。
记忆设备32能够用于接收并存储来自信息终端10的信息或者是与终端进行无线通讯的服务器,例如家用电脑,使用者之后会存取所述信息。而隐私是一个问题,设备32可以仅包括一个序列号,以确定设备32可以被与电子模块通信的安全服务器识别,在这种情形下,没有个人信息会被存储在设备32中。这样假使设备32丢失也可以防止私人信息被泄露。就目前揭露而言,只需要知道经授权的使用者可以通过设备32或是消费者忠诚卡上的条形码被本体14内的处理器识别,且处理器在电子模块内,举例来说可以与服务器和/或因特网无线通信,以基于之前存储的参数提供信息给信息终端的使用者。
可移动记忆设备32如图4,图27以及图29所示包括具有合适的紧凑型闪存或是其他固态记忆体35的主体34、可插入端口30的USB连接器36、盖子38以及环40或是类似的允许设备32连接到钥匙环上的设置。
如前面所论述的,信息终端10在室内和室外都适用,因而必须可以抵抗各种气候。基于这个理由,将无遮蔽的USB或其它I/O端口置于本体14的外面是不实际的。代替的,参考图26和图27,需要提供用来保护连接器30和本体内部的封包。图1所示的通道28设于本体14的上部,通道28也可以设在本体14的其它位置,并且通常朝向本体14的下部和/或以向上的角度的方式设置,以使直接暴露在雨雪中的部分最小化。
在一实施例中,图26和图27中的门150设于通道28中。门150与通道28的侧壁152构成密封,以使湿气进入在本体14内的开口的入口最小化。如图26所示,门150借助弹簧154偏向闭合位置,但可以在记忆设备34插入通道28时通过合叶156转开,如图27所示。从这些图示可以了解,门150在记忆设备34自本体14移除时会在弹簧154的作用下旋转闭合。
图28和29所示为通道28不同的闭合设置,包括设于通道28内的均通过弹簧162偏向闭合位置的第一和第二门160。如图29所示,通道28内插入的记忆设备34逆着弹簧162的弹力打开门160以提供到端口30的接入。当记忆设备34从通道28中移除时,门160在弹簧162的作用下返回闭合位置。
在某些时候可能需要提供用来紧固门150或门160的拴锁以降低外来物体被插入通道28的机会。通道28的大小通常小于成人的手指,但是孩子可能用小棒子或相似的物体损坏端口30。然而决心损坏信息终端14的成人将有可能损坏这样的拴锁,例如使用锤子以及螺丝起子,通过拴锁机构增加固持将阻止更多的不经意的损坏内部组件。
图30和31所示为安装于图26的门150上的第一栓锁机构。该机构包括可滑动的安装至门150上的闩锁件170,并且该拴锁件170被弹簧172或是图30和31中所示的单独的钩子176压入设于本体14的壁上的开口174中。销178延伸穿过门150并且被弹簧180保持在图30所示凸起的位置。电线182连接至销178的一端,且借助钉子184延伸至拴锁件170的端部。当销178如图31所示被记忆设备34压出时,电线182将拴锁件170拖离钩子176使门150在记忆设备34的推动下打开。
图32和33所示为另一结构的拴锁装置,其中一个或多个拴锁件190阻止门150打开。每一拴锁件190包括自通道28的侧壁152凸伸的凸轮面192以及邻近门150的栓锁端。插入通道28的记忆设备34因此向外推动凸轮面或表面192并且将拴锁端或端部194移出门150,藉此在记忆设备34被压住时让门150打开。拴锁件190相互独立操作。因此,当提供两个或三个拴锁件190时,不使用记忆设备34或相似尺寸以及形状的物体的话很难同时启动所有的拴锁件190。
图5所示为另一记忆体装置42。记忆体设备42在具有固态记忆体的主体44、USB连接器46、盖子48以及环50之外还包括具有预定形状的开启件52,本实施例中为十字架形。开启件52的形状与开启口54的形状相匹配,如图7以及图34至36所示,开启口54位于与端口30相邻的本体中。当使用记忆体装置42时,开启件52插入开启口54中。开启件52相对于连接器46更多的凸伸出主体44,因而会进入开启口54并启动松开机构56,其中松开机构56在端口30上打开门58。松开机构56包括可绕轴202旋转并连接至插销204的凸轮200,所以凸伸52施于凸轮200的压力可以转动凸轮并且将插销204自门58抽出,藉此让门58(仅其中之一在图35和36中示出)在USB连接器46压入时向内转动。而且,因为凸伸52相对于连接器46更多的凸伸出主体44,插销204一直处于图36所示收回的位置直到门58在记忆设备42自通道28抽出后关闭。这样的设置使得使用者在端口30上使用未经授权的设备更加困难。开启件52可以通过一个拇指划片(thumb slide)53收回,例如图5所示,使USB设备30可以适用于标准的USB端口,譬如说使用者家用计算机上的端口。
在启动本体14内的电子模块之外,插入的记忆体装置32或42还可以执行安全功能。如图9至图12所示,安装有信息终端10的购物车59包括用来稳定购物车车轮的轮锁装置,用来固定购物车的车轮。这些轮锁装置可包括用来选择性的驱动杆64进入轮子60的开口的螺线管62以防止轮子60转向。螺线管62可由本体14内的处理器发出的信号来控制,且只有当经授权的记忆体装置32,42插入端口30时解开轮子60。
图12所示为多个装有信息终端10的购物车70的嵌套。当车把手10安装在各种标准的购物车上时,其本体14的大小以及位置充分防止终端10与购物车嵌套相互干涉。此外,信息终端10安装的角度最好是使显示屏16与水平线之间成大约30度的夹角,以改善可见度和使反光最小化,且不会与购物车里的儿童座的使用或是购物车嵌套相干涉。
图13所示为用于对多个嵌套的购物车80,82,84的包括在本体14内的电池15进行再充电的菊花链的设置。从这些图示中明显可以看出,每一本体14包括有电源线86、电源插座88以及电源LED90,当购物车被供电时,其上的电源LED90会变亮。第一辆购物车80上的电源线86连接到合适的直流电源92(例如连接到交流电源的转接器),第二辆购物车82上的电源线86插入第一辆购物车80上的电源插座88,以及第三辆购物车84的电源线86插入第二辆购物车82上的电源插座88。当购物车连接到电源时,每一个购物车上的电源LED90变亮,通过这样的方式,可以很容易的判断出是否嵌套中的所有购物车都在被充电。这样的排列特别适合于后进先出的购物车安排,因而主要适用于在购买者使用的前一晚将一组购物车连接并完整充电的情形,或是另一种安排,嵌套的购物车中的每一个都可以单独的插入电源直到被完成充电。这允许在经过一个工作日后,将充电时间最长的购物车从购物车序列中先取出来。
图14所示的购物车围栏100具有第一以及第二栏杆102,如图17所示,每一栏杆102设有连接至电源103的导电电荷轨104。围栏100包括第一倾角与第二倾角导引部106以引导购物车进入围栏100。设于手柄12末端的电接触108与这些电荷轨104电性接触以对本体14内的电池15充电。电接触108也可以设于独立的端盖107上,端盖107可以在将握持部21截去适当长度后安装至手柄12。电接触108或是电荷轨104都可以是弹性的或是可替换的以保证电接触108与电荷轨104之间良好的电连接,即使栏杆102之间的间隙和或车把手10的末端之间的间隙不是恒定的。可选地,端盖107可以可伸缩的安装于手柄12内且彼此弹性偏离以适应导电轨102之间不同的间隙。围栏100可以进一步包含合叶片112或是类似的结构以保证购物车从单一方向经过围栏,并且充电时间最长的购物车可以先取走以提供先进先出的充电。
图18所示为整合入菊花链购物车安全系统的充电系统。在这样的安全系统中,嵌套的购物车通过将链接于一个购物车的元件114插入到相邻购物车的狭槽116中来固定。元件114可以通过插入硬币或是代币(token)来释放元件114从而以解开一个购物车。硬币或是代币在购物车使用完毕后放回购物车嵌套时被返还。在Lenader的美国专利4,474,282中阐述了一个这样的菊花链锁扣系统(不包含本发明中的电子充电系统)的例子,其内容于此一并参考。
如图19和图20所示,元件114包括与狭槽116中的锁扣机构连接的搭扣115以及与狭槽116中的电接触120配合以使两购物车电性连接的电接触118。在狭槽116中的电接触120通过线缆121与链接至购物车的元件的电接触118依次连接,该元件可以用相似的方式插入相邻购物车的狭槽116以电性连接并使串联的嵌套购物车相互固定。
图21所示为包含安装在壁132上的单一轨道130的充电系统。轨道130包括安装有一对有间隔的电接触134的通道133,用来与设在购物车把手138端部的一对垂直凸伸的电接触136进行电性连接。在靠近轨道130的地面上设有引导通道140,以辅助导引购物车的车轮并相对于轨道130恰当的安置车把手138。这样的安排空间效率高并且允许通过购物车把手的一端对电池充电。
根据几个较佳实施例对本发明进行了描述,显而易见的增加和修改对任何熟悉本项技术的人员在对上述说明书阅读之后是显然的,在不脱离本发明的精神和范围内,可在此基础上做进一步的改进和变化,所有显而易见的修改和增加均应包括在本发明的保护范围内。
