    • A signal analyzer system comprises a differential operator configured to receive at least one input signal, and to determine at least one locus based on instantaneous differences in a relative rate of change between the at least one input signal and the at least one input signal's at least one nth-order derivative, wherein n represents at least one selected order of differentiation. A distortion identifier is configured to compare at least one amplitude of the at least one determined locus against at least one selected reference locus, and to identify at least one distortion in the signal when the comparison indicates at least one selected exception condition.
    • 信号分析器系统包括差分运算器,其被配置为接收至少一个输入信号,并且基于至少一个输入信号和至少一个输入信号之间的至少一个输入信号的相对变化速率的瞬时差异来确定至少一个轨迹 一个第n个 - 级衍生物,其中n表示至少一个选择的分化顺序。 失真标识符被配置为将所述至少一个确定的轨迹的至少一个幅度与至少一个所选择的参考轨迹进行比较,并且当所述比较指示至少一个选择的异常状况时,识别所述信号中的至少一个失真。

    • A improved method and apparatus are provided for casting objects. The apparatus includes a molten metal or liquid retaining container with a bottom feed outlet, a casting chamber with a bottom feed inlet, and a connecting portion through which molten metal or liquid from the container portion flows into the casting mold. The melt flows from the melt container to the casting chamber through the hollow connecting portion by movement of the relative positions of the melt container and the casting chamber, allowing for a controlled casting method with a minimum of turbulence.
    • 提供了一种用于铸造物体的改进的方法和装置。 该设备包括具有底部进料出口的熔融金属或液体保持容器,具有底部进料入口的铸造室和来自容器部分的熔融金属或液体通过该连接部分流入铸模中。 通过熔体容器和铸造室的相对位置的移动,熔体通过中空连接部分从熔体容器流到铸造室,允许以最小湍流的受控铸造方法。

    • A technique is disclosed for preventing un-authorized attachment of computer peripherals to a computer or computer network. Illustrative embodiments comprise two mating keyed-adapters between network/host computer ports and peripheral ports. One or both adapters can contain hardware for enabling and disabling communications to and from peripherals under software control from a host computer. The peripheral-side adapter contains a first hardware for storing a unique identifier corresponding to the attached peripheral. The host computer retrieves this stored identifier and compares it to a database of authorized identifiers. If a match is found, then communication to and from the peripheral is enabled either in a second hardware within the adapter or software within the host computer. If a match is not found, then communication to and from the peripheral is not permitted.
    • 公开了一种防止计算机外围设备未经授权的附着到计算机或计算机网络的技术。 示例性实施例包括网络/主计算机端口和外围端口之间的两个配对密钥适配器。 一个或两个适配器可以包含用于在主机的软件控制下启用和禁用与外围设备通信的硬件。 外围设备适配器包含用于存储对应于连接的外围设备的唯一标识符的第一硬件。 主机检索该存储的标识符并将其与授权标识符的数据库进行比较。 如果找到匹配,则在适配器或主计算机内的软件中的第二个硬件中启用与来自外围设备的通信。 如果没有找到匹配,则不允许与外设进行通信。
