    • Methods and apparatus for reducing the bandwidth required to transmit analog information. The analog information is converted to digital data organized in time defined blocks of information called frames. The content of a frame may be modeled as a composite of superimposed objects, which are subsets of information in the frame, that are largely unchanged frame to frame. Each object in a present frame may be represented by an identification of the object and a description of the changes in object-to-frame relationship that occurred from a previous frame to the present frame. The objects in the present frame may then be reconscructed by adjusting the objects in the previous frame in accordance with the change in object-to-frame relationships.
    • 减少传输模拟信息所需带宽的方法和装置。 模拟信息被转换为以时间定义的称为帧的信息块组织的数字数据。 帧的内容可以被建模为叠加对象的组合,叠加对象是帧中的信息子集,其基本上是帧到帧不变的。 当前帧中的每个对象可以由对象的标识和从先前帧到当前帧发生的对象到帧之间关系的改变的描述来表示。 然后,可以根据对象到帧之间的关系的变化来调整当前帧中的对象,以通过调整前一帧中的对象来重新生成。

    • Disclosed is a process for manufacturing an aromatic diacid in one step with a single catalyst system which comprises: a) Introducing into a reactor an aromatic hydrocarbon containing the number of rings desired in the product diacid with one or more alkyl groups attached to the rings; b) Reacting said aromatic hydrocarbon in the presence of an oxidant supply and a single catalyst system comprising at least one catalyst selected from Group IB, IIB, VB, or VIIB of the Periodic Table, in a reaction medium capable of stabilizing the aromatic acids formed against further oxidation to water and CO2, or decarboxylation to aromatic hydrocarbons, and also capable of allowing the isomerization of the acids so formed to the desired diacids; and c) Reacting said hydrocarbon feed with said oxidant in the presence of said catalyst system until a desired amount of said feed is oxidized to carboxylic acids and isomerized to the desired diacid product.
    • 公开了一种用单一催化剂体系制备芳族二酸的方法,该方法包括:a)向反应器中引入含有产物二酸中期望的数目的环的芳族烃与一个或多个连接到环上的烷基; b)在氧化剂供应和包含至少一种选自元素周期表IB,IIB,VB或VIIB族的催化剂的催化剂体系的存在下,在能够稳定形成的芳族酸的反应介质中使所述芳烃反应 防止进一步氧化成水和二氧化碳,或对芳烃脱碳,并且还能够使所形成的酸异构化成所需的二酸; 和c)在所述催化剂体系的存在下,用所述氧化剂使所述烃进料反应,直到所需量的所述进料被氧化成羧酸并异构化为所需的二酸产物。
