    • The apparatus for symbol boundary synchronization in one embodiment includes on the receive path of a multi-tone modem a window synchronizer, a converter and a symbol boundary component. The window synchronizer obtains windowed portions of the received datastream which includes symbols each expressed with a corresponding set of tones in a time domain. The windowed portions obtained in the training phase exhibit varying degrees of misalignment with the corresponding symbol boundaries. The window synchronizer is responsive to an alignment signal to obtain succeeding windowed portions of the incoming datastream aligned with the corresponding symbol boundaries therein. The converter couples to the window synchronizer to convert the set of tones from each windowed portion from the time domain to a frequency domain. The symbol boundary module couples to the converter to evaluate a phasor angle characteristic of selected tones from each windowed portion converted by the converter and to convert the phasor angle characteristic of the selected tones from a selected one of the windowed portions to the alignment signal to align the window synchronizer with the symbol boundaries in the received datastream. In an alternate embodiment of the invention the symbol boundary component couples to the window synchronizer to correlate sign values of the selected tones with a reference set and to output the alignment signal identifying the corresponding windowed portion which exhibits maximum correlation with the reference set to align the window synchronizer.
    • 在一个实施例中,用于符号边界同步的装置在多音调制解调器的接收路径上包括窗口同步器,转换器和符号边界部件。 窗口同步器获得接收到的数据流的窗口化部分,其包括在时域中用相应的一组音调表示的符号。 在训练阶段获得的窗口部分与相应的符号边界呈现不同程度的不对准。 窗口同步器响应于对准信号以获得与其中的对应符号边界对准的输入数据流的后续窗口部分。 转换器耦合到窗口同步器,以将来自每个窗口部分的音调集从时域转换到频域。 符号边界模块耦合到转换器以评估来自由转换器转换的每个窗口部分的所选音调的相量角特性,并将所选择的音调的相量角特性从所选择的一个窗口部分转换为对准信号以对准 窗口同步器与接收到的数据流中的符号边界。 在本发明的替代实施例中,符号边界分量耦合到窗口同步器以将所选择的音调的符号值与参考集相关联,并输出识别与参考集合具有最大相关性的对应窗口部分的对准信号,以对准 窗口同步器

    • Precooked and partially debranned corn flour is continuously produced by an enzymatic precooking using a commercial endoxylanase and endoamylase blend as a processing aid. The low-temperature and near neutral-pH precooking with an endoxylanase and endoamylase solution effects a partial hydrolysis of bran and starchy cell-walls with a controlled gelatinization and reduced conditioning and corn solid loss in wastewater. Moisture content is then stabilized after washing, followed by milling and drying at a high temperature for a short time to produce a partial gelatinization in the ground kernel, cooling and further drying the dried-milled particle. A fine particle size or flour is separated and recovered from the coarser particle which is also segregated to isolate a light bran fraction for integral flour or feed use, remilling and sieving the coarser particle to produce an instant corn flour for snack chip and corn-based food, and admixing the fine particle with lime to obtain a masa flour for tortillas and the like.
    • 使用商业内切木聚糖酶和内切淀粉酶混合物作为加工助剂,通过酶预预煮连续生产预煮和部分脱壳的玉米粉。 用内切木聚糖酶和内切酶酶溶液进行低温和接近中性pH预煮,可以控制糊化,并且减少了废水中的调理和玉米固体损失,从而部分水解了麸皮和淀粉样细胞壁。 洗涤后水分含量稳定,随后在高温下研磨和干燥短时间,以在研磨的核中产生部分糊化,冷却并进一步干燥干燥的磨碎颗粒。 细粒度或面粉从较粗颗粒分离并回收,粗颗粒也被分离,以分离用于整体面粉或饲料用途的轻糠级分,对较粗颗粒进行再搅拌和筛分以产生用于小吃片和玉米基的即食玉米粉 食物,并将细颗粒与石灰混合,得到玉米粉饼等的马萨粉。

    • A vehicle disabling device for disabling a fleeing vehicle has a carriage that is projected from a launch platform using a plurality of elongate extension tubes. The plurality of elongate extension tubes are pneumatically actuated with a tank of compressed air operably connected to the plurality of elongate extension tubes with a pneumatic hose. The carriage includes a pair of carriage wheels and is adapted for rectilinear movement in front of a pursuit vehicle. The carriage also includes a first arm and a second arm connected pivotally to the carriage. A plurality of spikes are disposed along the first and second arms, adapted to puncture the tires of the fleeing vehicle once the fleeing vehicle has run over one of the first and second arms.
