    • 736-005 48 IMPROVED OPTICAL READERS To read optically encoded information over a wide range of densities, the present invention provides a spacer system on the tip of an optical reader. The optical reader may be a contact wand type device, for example including a fixed laser emitter. Alternatively, the optical reader may be a moving spot scanner. In either case, the emitter element of the optical reader produces a diverging beam of light. During a reading operation, the spacer contacts the object surface on which optically encoded indicia is formed. The spacer selectively defines at least two different distances between the light emitter, or the focal point of the emitted beam of light, and the object surface. Because of the beam divergence, the diameter of the beam at its point of impact on the object surface will be different for each of the two different distances. The different beam diameters provide the optical reader with different effective sensing spots for reading different density symbols. The present invention also incorporates an optical reader, typically a moving spot laser scanner, into a number of different types of computer data input devices, such as the stylus of a digitizer table and a computer "mouse." In one such integrated terminal embodiment, the optical reader is combined with a touch sensitive display and data input device.

    • A system for recording, analyzing, editing, and playback of scents is disclosed. A scent can be sampled and represented in various manners, such as by reference to an activation pattern of olfactory receptors (determined experimentally or by using computer programs), description of chemical structure, description of its characteristics by a panel of human subjects, or its pattern of interaction with an artificial scent-sensing device (an "artificial nose" device). A scent emitter having a set of chemicals which can be volatilized is disclosed for re-creation of the scents from the stored scent representation. The scent representation can be transmitted over computer networks, such as the Internet, for re-creation at remote locations, and can be stored for re-creation of the scent at times different from the time of sampling of the scent. The system finds applications in advertisements which may appear on pages on the World Wide Web, in re-creating scents for forensic or quality control analysis, as enhancements to virtual reality simulations, custom creation of scents by scent designers, and other uses.
    • 公开了用于记录,分析,编辑和播放气味的系统。 可以以各种方式对气味进行采样和表示,例如参考嗅觉受体的激活模式(通过实验或通过使用计算机程序确定),化学结构的描述,人类受试者的特征描述,或其 与人造气味感测装置(“人造鼻”装置)的相互作用模式。 公开了具有可以挥发的一组化学品的香味发射器,用于从存储的气味表示重新创建气味。 气味表示可以通过计算机网络(例如因特网)传输,用于在远程位置重新创建,并且可以存储用于在与气味取样时间不同的时间重新创建气味。 该系统在广告中找到可能出现在万维网页面上的应用程序,重新创建用于取证或质量控制分析的气味,作为虚拟现实模拟的增强功能,由香味设计师定制创建气味和其他用途。
