    • An enterprise content management system such as an electronic contract system manages a large number of secure documents for many organizations. The search of these private documents for different organizational users with role-based access control is a challenging task. A content-based extensible mark-up language (XML)-annotated secure-index search mechanism is provided that provides an effective search and retrieval of private documents with document-level security. The search mechanism includes a document analysis framework for text analysis and annotation, a search indexer to build and incorporate document access control information directly into a search index, an XML-based search engine, and a compound query generation technique to join user role and organization information into search query. By incorporating document access information directly into the search index and combining user information in the search query, search and retrieval of private contract documents can be achieved very effectively and securely with high performance.
    • 诸如电子合同系统的企业内容管理系统为许多组织管理大量安全文件。 对具有基于角色的访问控制的不同组织用户搜索这些私有文档是一项具有挑战性的任务。 提供了基于内容的可扩展标记语言(XML) - 注意安全索引搜索机制,其提供具有文档级安全性的私人文档的有效搜索和检索。 搜索机制包括用于文本分析和注释的文档分析框架,搜索索引器,将文档访问控制信息直接构建到搜索索引中,基于XML的搜索引擎和复合查询生成技术,以加入用户角色和组织 信息进入搜索查询。 通过将文档访问信息直接并入搜索索引并将搜索查询中的用户信息结合起来,可以以高性能非常有效和安全地实现私人合同文档的搜索和检索。

    • An RF/ID interrogator recovers a backscattered data signal from a moving RF/ID transponder by combining the received in-phase (I) and quadrature-phase (Q) components of the signal in a manner that cancels out the amplitude nulls and phase reversals caused by movement of the RF/ID transponder. More particularly, the RF/ID interrogator comprises a radio having a transmitter portion to provide an RF carrier signal and a receiver portion to receive the I and Q signals from the RF transponder. A bandpass filter is coupled to the radio to remove direct current (DC) components from the I and Q. A processor coupled to the radio and the filter executes stored instructions to combine the filtered I and Q signals and recover the original backscattered data signal therefrom. In an embodiment of the invention, the processor estimates a phase angle .beta.(t) between the I and Q signals and the RF carrier by calculating an arctangent of a ratio of the filtered Q and I signals. Thereafter, the processor recovers the backscattered data signal by summing a product of the filtered I signal and the cosine of the estimated phase angle .beta.(t) with a product of the filtered Q signal and the sine of the estimated phase angle .beta.(t).
    • RF / ID询问器通过组合接收的信号的同相(I)和正交相(Q)分量,以消除幅度零相位和相位反转的方式,从移动RF / ID转发器恢复背散射数据信号 由RF / ID转发器的移动引起的。 更具体地,RF / ID询问器包括具有发射机部分以提供RF载波信号的无线电和接收来自RF应答器的I和Q信号的接收机部分。 带通滤波器被耦合到无线电装置以从I和Q去除直流(DC)分量。耦合到无线电装置的处理器和滤波器执行存储的指令以组合经滤波的I和Q信号并从其中恢复原始反向散射数据信号 。 在本发明的一个实施例中,处理器通过计算滤波Q和I信号的比值的反正切来估计I和Q信号与RF载波之间的相位角β(t)。 此后,处理器通过将滤波后的I信号与估计的相位角β(t)的余弦乘以滤波的Q信号与估计的相位角β(t)的正弦的乘积相加来恢复反向散射数据信号, 。

    • The present invention is directed to systems and methods that treat the monitoring of a software application as a separate and independent concern from the software application itself. The present invention utilizes aspect oriented programming to intercept, analyze, decompose the application states of a software application and then to link appropriate non-invasive constructs into the software application code to provide application state information to an autonomic manager through a plurality of sensors. The autonomic manager analyzes the application state information for compliance pre-defined parameters, and takes appropriate corrective action including modifying the software application states using a plurality of effectors. The sensors and effectors are linked as non-invasive constructs to the software application, and in aspect oriented programming constitute aspects. In order to prevent any adverse or undesirable effects to the software application as a result of the application state analysis and selected action, a safety mechanism is included in communication with the effectors.
