    • Various embodiments described herein provide systems, methods, software, and data structures that allow a page description language reader application, such as Adobe® Acrobat®, to provide a view of the assets compressed within a compressed archive. These and other embodiments including applications that may interleave one or more compressed archives within a page description language file, such as a PDF file. This interleaving leverages properties of both compressed archive files and page description language files to insert object markers around compressed assets within the compressed archives and references to at least some of the object markers in an index portion of the page description language files. As a result, compressed assets of compressed archives included in a page description language file package may be viewed within the listing of assets of the page description language file. These and other embodiments are described in greater detail below.
    • 本文所描述的各种实施例提供允许诸如Adobe Acrobat的页面描述语言阅读器应用程序提供在压缩归档内压缩的资产的视图的系统,方法,软件和数据结构。 这些和其他实施例包括可以在页面描述语言文件(例如PDF文件)内交织一个或多个压缩档案的应用程序。 这种交错利用压缩存档文件和页面描述语言文件的属性来在压缩归档内的压缩资产周围插入对象标记,并引用页面描述语言文件的索引部分中的至少一些对象标记。 因此,可以在页面描述语言文件的资产列表内查看包含在页面描述语言文件包中的压缩归档的压缩资产。 下面更详细地描述这些和其它实施例。

    • A method and apparatus are presented to perform a distributive computation of a digital signature in a document signing process. A signing request from a remote device initiates the document signing process including the distributive computation. The server verifies digital certificates corresponding to a signer's public key. An encryption request including a set of authenticated attributes and a hash value based on the to-be-signed content is transmitted to the remote device. A signer at the remote device encrypts the hash value in the encryption request with an encryption process utilizing a private key. The resulting encrypted hash value is transmitted to the server to produce the digital signature used to sign the subject content. This distributive computation process minimizes the amount of data transmitted between devices, while minimizing remote device resource requirements, and maintains the integrity of the signer's private key during generation of the digital signature.
    • 提出了一种在文档签名过程中执行数字签名的分布式计算的方法和装置。 来自远程设备的签名请求启动文档签名过程,包括分发计算。 服务器验证与签名者的公钥相对应的数字证书。 将包含一组认证属性和基于待签名内容的哈希值的加密请求发送到远程设备。 远程设备的签名者使用私钥加密加密请求中的哈希值。 所产生的加密散列值被发送到服务器以产生用于签署主题内容的数字签名。 这种分布式计算过程最小化在设备之间传输的数据量,同时最小化远程设备资源需求,并且在生成数字签名期间维护签名者的私钥的完整性。

    • An open frame chassis has a top opening and a bottom opening permitting ambient airflow. A plurality of modules, each enclosing electrical components in thermal contact with a heat sink area of their corresponding module, can each be inserted in the chassis. Ambient air may flow from the bottom opening across the heat sink area of each module to the top opening to passively cool the modules and electrical components. Key pins guide the modules into place and prevent incorrect insertion of a different type of electrical module not corresponding to the electrical connection of the chassis for that slot. Guide pins on corners of the modules mate with guide holes in the chassis to secure the module to the chassis and decrease vibration. Both sides of the chassis have side openings through which the fins of the modules in the end slots of the chassis may be exposed.
    • 开放框架底盘具有顶部开口和允许环境气流的底部开口。 每个封闭与其相应模块的散热器区域热接触的电气部件的多个模块可以各自插入到底盘中。 环境空气可以从底部开口流过每个模块的散热器区域到顶部开口,以被动地冷却模块和电气部件。 钥匙销将模块引导到位,并防止不正确插入不同于该插槽的机箱电气连接的不同类型的电气模块。 模块角上的导销与机箱中的导向孔配合,将模块固定在机箱上,减少振动。 底盘的两侧具有侧开口,底架的端部槽中的模块的翅片可以穿过该开口露出。

    • Embodiments for caching database information are disclosed. A query may specify a set of information to be retrieved from a database file. The database file may be parsed according to the query to retrieve the set of information. The query and the corresponding set of information retrieved from the database file may be stored in a cache file. The cache file may be searched for the query, which may enable the set of information to be retrieved from the cache file. Searching the cache file and retrieving the set of information from the cache file may be faster than searching the database file to retrieve the set of information. The cache file may be associated with a currency token which may indicate whether the cache file is current. The currency token may indicate whether the database file has been updated since being parsed according to the query.
    • 公开了缓存数据库信息的实施例。 查询可以指定要从数据库文件检索的一组信息。 可以根据查询来解析数据库文件以检索该组信息。 从数据库文件检索的查询和相应的信息集可以存储在高速缓存文件中。 可以搜索缓存文件的查询,这可以使得能够从高速缓存文件检索信息集。 搜索缓存文件并从缓存文件中检索信息集可能比搜索数据库文件以检索该信息集更快。 高速缓存文件可以与可以指示高速缓存文件是否为当前的货币令牌相关联。 货币令牌可以指示数据库文件是否已经根据查询进行了解析而被更新。
