    • Systems and methods are described for using topographic and/or contrast spot scanning to facilitate various types of functionality in context of a data storage library. A robotic mechanism includes a hand assembly that has one or more integrated spot scanners. The hand assembly is configured to travel in at least two directions and to rotate, thereby locating and/or pointing the spot scanner in desired locations throughout the data storage library. By sweeping the spot scanner across a scan window, contrast and/or topographic data can be acquired and decoded to generate a profile of a region. The profile can be interpreted to facilitate functions, such as calibration of robot location with respect to media cartridges, targeting, proximity detection, empty cell detection, etc.
    • 描述了使用地形和/或对比度点扫描来促进数据存储库的上下文中的各种类型的功能的系统和方法。 机器人机构包括具有一个或多个集成点扫描仪的手组件。 手组件被配置成在至少两个方向上移动并旋转,从而将斑点扫描器定位和/或指向整个数据存储库中的所需位置。 通过在扫描窗口上扫描光点扫描器,可以获取和解码对比度和/或地形数据以生成区域的轮廓。 该简档可以解释为便于功能,例如相对于介质盒的机器人位置的校准,瞄准,接近检测,空单元检测等。

    • Magnetic media containing data and method for data verification are disclosed. The data verification method utilizes the relative position of specific features of magnetic media signals, such as, peak zero crossings, the ratio of preselected amplitudes, the locii of preselected points along the signal, the RMS value of the waveform and the like. In the preferred embodiment, the ratio of the separation of adjacent pulses in the signal is employed. The deviation of the precise location of the placement of the peak points in the signal waveform is referred to as "jitter". This "jitter" is enhanced to provide a pattern of "jitter" or a magnetic "signature" that is random, non-reproducible and that can be used to positively identify a particular specimen of magnetic media and the associated data. The magnetic jitter pattern or security signature can be separate from or an integral part of the data recorded on the magnetic media. The data verification method and magnetic media have particular application in the field of credit cards.
    • 公开了包含用于数据验证的数据和方法的磁性介质。 数据验证方法利用磁性媒体信​​号的特定特征的相对位置,例如峰值过零点,预选幅度的比率,沿着信号的预选点的位置,波形的RMS值等。 在优选实施例中,采用信号中相邻脉冲的分离比。 信号波形中的峰值点的位置的精确位置的偏差被称为“抖动”。 这种“抖动”被增强以提供“抖动”或磁性“签名”的模式,其是随机的,不可重现的,并且可以用于肯定地识别特定的磁性介质样本和相关联的数据。 磁性抖动图案或安全签名可以与记录在磁性介质上的数据分开或不可分割的部分。 数据验证方法和磁性介质在信用卡领域具有特殊的应用。

    • A method and the means for practicing the method is disclosed for verifying the encodation accuracy of a Universal Product Code master symbol that is to be printed on a consumer product carton or the like. The means for practicing the method consists of an Encodation Verifier which is preferably printed on a piece of film or glass and which includes 113 numbered light spaces and dark bars which represent the total modules of the code symbol, and an Encodation Worksheet form on which information obtained form comparing the Encodation Verifier with the symbol to be verified, is entered. Thus, the method for verifying the symbol encodation comprises a graphic comparison of the Encodation Verifier with the symbol to be verified. The method is preferably practiced visually under low power magnification but could be done mechanically with an optical device such as a reader/printer machine.

    • A method and apparatus to deskew dead cycles is described using a block aligner. In one example a method includes receiving a sequence of bytes into a first buffer from each lane of a multiple lane peripheral device bus and receiving the sequence of bytes into a second buffer delayed one clock cycle from the first buffer. The method further includes providing the sequence of bytes from the first buffer to an output buffer, counting clock cycles of data as the data is received into the first and second buffers, upon reaching a predetermined count, inserting a dead cycle into the output buffer, and after inserting the dead cycle providing the sequence of bytes from the second buffer instead of the first buffer to the output buffer.
