    • A heat exchanger evaluation system (84) includes a refrigeration subsystem (126) and a platform (94) in communication with the subsystem (126) for attachment of a heat exchanger (32). The system, (84) further includes a thermal imaging camera (168) and a monitor (100). A method (180) entails routing a fluid (38) through the heat exchanger (32) via the refrigeration subsystem (126). The camera (168) detects the temperature variation across the heat exchanger (32) as the fluid (38) flows through the heat exchanger, and provides successive thermal images representing the temperature variation responsive to the flow of the fluid (38). The thermal images are utilized to determine an efficacy of the flow through the heat exchanger (32). In particular, a determination can be made as to whether the flow deviates from a pre-determined flow path (79) of the fluid (38) through the heat exchanger.
    • 热交换器评估系统(84)包括与用于附接热交换器(32)的子系统(126)连通的制冷子系统(126)和平台(94)。 该系统(84)还包括热成像相机(168)和监视器(100)。 方法(180)需要经由制冷子系统(126)将流体(38)路由穿过热交换器(32)。 当流体(38)流过热交换器时,照相机(168)检测穿过热交换器(32)的温度变化,并响应于流体(38)的流动提供代表温度变化的连续热图像。 热图像用于确定通过热交换器(32)的流动的功效。 特别地,可以确定流体是否偏离流体(38)的预定流动路径(79)通过热交换器。

    • A communication system providing telephony communication across combined circuit switched and packet switched networks, such as a telephone network and the Internet, which are connectable to terminals, such as telephones and computers, for selective communication therebetween. The communication system includes an authorization and account control object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an information retrieval object in the packet switched network, wherein the authorization and account control object maintains a substantially real time record of user accounts and usage, and the information and retrieval object provides substantially real time retrieval of selected information from the authorization and account control object. The retrieval object provides on demand to terminals which provide authentication for access to an identified account information regarding that account. The information regarding the account is substantially real time information including information with respect to communications in progress, which are chargeable to the account which has been authenticated. The authorization and account control object is preferably a unitary logical object having distributed instances thereof handling multitudinous accounts of widely separated terminals. The retrieval object provides isolation of the authorization and account control object permitting simultaneous multitasking by the authorization and account control object and the retrieval object respectively.
    • 一种通过组合电路交换和分组交换网络(例如电话网络和因特网)提供电话通信的通信系统,其可连接到诸如电话和计算机之类的终端,用于其间的选择性通信。 通信系统包括分组交换网络中的授权和帐户控制对象,电路交换和分组交换网络之间的多个网关,提供这些网络之间的受控连接,以及分组交换网络中的信息检索对象,其中授权和帐户控制 对象维护用户帐户和使用的基本实时记录,并且信息和检索对象从授权和帐户控制对象提供基本上实时检索所选择的信息。 检索对象根据需要提供终端,该终端提供用于访问关于该帐户的所识别的帐户信息的认证。 关于账户的信息基本上是实时信息,包括关于正在进行的通信的信息,这些信息可以对已被认证的帐户收费。 授权和帐户控制对象优选地是具有分布式实例的单一逻辑对象处理广泛分离的终端的众多帐户。 检索对象提供授权和帐户控制对象的隔离,允许分别由授权和帐户控制对象和检索对象同时进行多任务。
