    • In order to improve security for holographic labels which are positioned on a substrate base, a bar code symbol with regions of different light reflective properties is holographically recorded on the base. The base may be, for example an information card, such as a credit card, a label, or a container for a product. The bar code symbol can be recorded so that it is visible to the eye in white light (e.g., as a rainbow hologram) or so that it requires an appropriate reference beam for reconstruction. A reading apparatus (e.g., a bar code reader) directs light at the holographic bar code symbol and detects the reflected optical information with a detector such as a CCD array. The reading apparatus can be a stand-alone device or, in the case of a credit card, can be incorporated into a conventional swiper for reading magnetic information on a strip on the card. A non-holographic bar code symbol can also be provided on or near a holographic display element, e.g., a rainbow hologram. The bar code can be positioned adjacent the display, or placed in a window within the display, or etched or embossed on the display. A system is also provided for authenticating a holographic display on an information card such as a credit card. A display is illuminated and a reflected beam directed at a holographic record which was previously produced from a signal, known to be authentic, and a reference. The reflected beam is used to reconstruct a reference beam. A sensor receives the reconstructed reference and it is then determined if the display is authentic.
    • 为了提高位于基板基板上的全息标签的安全性,具有不同光反射特性的区域的条形码符号全息地记录在基座上。 基座可以是例如用于产品的信息卡,例如信用卡,标签或容器。 可以记录条形码符号,使得其在白光(例如,作为彩虹全息图)中可见于眼睛,或者使得其需要用于重建的适当的参考光束。 读取装置(例如,条形码阅读器)将光引导到全息条形码符号,并用诸如CCD阵列的检测器检测反射的光学信息。 读取装置可以是独立装置,或者在信用卡的情况下,可以并入到用于读取卡上的条带上的磁信息的常规的卡片中。 也可以在全息显示元件上或附近提供非全息条形码符号,例如彩虹全息图。 条形码可以定位在显示器附近,或者放置在显示器内的窗口中,或者蚀刻或压印在显示器上。 还提供了一种用于在诸如信用卡的信息卡上认证全息显示的系统。 照明的显示器和指向全息记录的反射光束,其先前由已知是真实的信号产生,并且是参考。 反射光束用于重构参考光束。 传感器接收重建的参考,然后确定显示器是否可信。

    • A portable data input or computer system includes an input/output device such as a keyboard and a display, another data input device such as an optical bar code scanner, and a data processor module. To scan bar code type indicia, the operator points the scanner at the bar code and triggers the scanner to read the indicia. All the system components are distributed on an operator's body and together form a personal area system (PAS). Components may include a scanner or imager, a wrist unit, a headpiece including an eyepiece display, speaker and a microphone. Components within a particular PAS communicate with each other over a personal area network (PAN). Individual PASs may be combined into a network of PASs called a PAS cluster. PASs in a particular PAS cluster can communicate with each other over another wireless communication channel. Individual PAS can gain access to a Local Area Network (LAN) and/or a Wide Area Network (WAN) via an access point. Individual PASs can use devices, such as servers and PCs situated either on the LAN or the WAN to retrieve and exchange information. Individual PAS components can provide automatic speech and image recognition. PAS components may also act a telephone, a pager, or any other communication device having access to a LAN or a WAN. Transmission of digitized voice and/or video data can be achieved over an Internet link.
    • 便携式数据输入或计算机系统包括诸如键盘和显示器之类的输入/输出设备,诸如光学条形码扫描器的另一数据输入设备和数据处理器模块。 要扫描条形码类型标记,操作员将扫描仪指向条形码并触发扫描仪读取标记。 所有系统组件分布在操作员的身体上,并且一起形成个人区域系统(PAS)。 组件可以包括扫描器或成像器,腕部单元,包括目镜显示器,扬声器和麦克风的头戴耳机。 特定PAS中的组件通过个人区域网络(PAN)彼此通信。 个人PAS可以组合成称为PAS集群的PAS网络。 特定PAS集群中的PAS可以通过另一无线通信信道彼此通信。 个人PAS可以通过接入点访问局域网(LAN)和/或广域网(WAN)。 个人PAS可以使用设备,如位于LAN或WAN上的服务器和PC来检索和交换信息。 个人PAS组件可以提供自动语音和图像识别。 PAS组件还可以对电话,寻呼机或具有访问LAN或WAN的任何其他通信设备起作用。 数字化语音和/或视频数据的传输可以通过因特网链路实现。
