    • A framework for use with object-oriented programming systems includes one or more objects of a class called “Socket” that receive and process packets of work. As various applications execute, they require servicing of tasks, which correspond to the packets of work mentioned above. The packets of work are represented in the framework by objects of a class called “WorkUnit”. When a WorkUnit object is generated by an application, it in turn generates an object of a class called “Retriever” which is associated with the appropriate Socket object needed for servicing the WorkUnit. The Retriever object retrieves the Socket object to service the WorkUnit from an object of a class called “SessionInfo”. The SessionInfo object is a single object for maintaining registries of Socket objects and objects of a class called “ApplicationInfo”. ApplicationInfo objects contain application specific information that can be used, manipulated, and shared between one or more WorkUnits of a given application. WorkUnits of an application can retrieve ApplicationInfo objects from the SessionInfo object by use of a Retriever object which is associated with the appropriate ApplicationInfo object. The framework includes a core set of objects, including SessionInfo, Socket, ApplicationInfos, Retrievers, and WorkUnits, and permits user-defined, extensible instances of these objects that permit tailoring of tasks for particular needs.
    • 用于面向对象编程系统的框架包括接收和处理工作包的称为“Socket”的类的一个或多个对象。 随着各种应用的执行,它们需要对与上述工作相对应的任务进行服务。 工作包在框架中由称为“WorkUnit”的类的对象表示。 当一个应用程序生成一个WorkUnit对象时,它又产生一个名为“Retriever”的类的对象,该对象与为WorkUnit进行维护所需的适当Socket对象相关联。 Retriever对象从一个名为“SessionInfo”的对象中检索Socket对象以对WorkUnit进行服务。 SessionInfo对象是用于维护Socket对象和名为“ApplicationInfo”的类的对象的注册表的单个对象。 ApplicationInfo对象包含可以在给定应用程序的一个或多个WorkUnits之间使用,操纵和共享的应用程序特定信息。 应用程序的WorkUnits可以通过使用与适当的ApplicationInfo对象关联的Retriever对象从SessionInfo对象中检索ApplicationInfo对象。 该框架包括一组核心的对象,包括SessionInfo,Socket,ApplicationInfos,Retrievers和WorkUnits,并允许这些对象的用户定义的可扩展实例,允许为特定需求定制任务。

    • The apparatus of this invention are multiple fish surrogates that each have plurality of piezoelectric and triaxial accelerometer sensors for emulating sensory organs of a particular fish. The multiple fish surrogates are immersed in flowing water intakes of a hydraulic structure such as: intakes, intake bypasses, and diversion structures; or also natural geological formation such as riffles, shoal areas, and pools. The invention is used for acquisition of acoustic and fluid dynamic data in or near these hydraulic structures and natural formations. To accomplish this, multiple sensors in multiple fish-shaped physical enclosures are deployed at the same time to describe a fish's aquatic environment at locations such as in proximity to a dam's intake. Since such an intake exhibits turbulent and high energy flow fields that cannot be characterized by a single sensor, many sensor bodies are required for a complete characterization of the environment. Similar deployment of the multiple sensor fish bodies can be made in complex natural channels to describe their acoustic fields and hydrodynamic fields. Such data are correlated with fish behavior for the purpose of developing methods of diverting fish from such areas of danger of a water intake or to attract them to a water bypass entrance system.
    • 本发明的装置是多个鱼类替代物,每个鱼类代用品具有多个用于模拟特定鱼的感觉器官的压电和三轴加速度计传感器。 多个鱼类代用品浸入水力结构的流入水中,如:进气口,进气旁路和分流结构; 还有自然地质构造,如ri les,浅滩地区和游泳池。 本发明用于在这些水力结构和自然地层中或附近获取声学和流体动力学数据。 为了实现这一点,同时部署多个鱼形物理外壳中的多个传感器来描述在诸如靠近大坝入口的位置处的鱼的水生环境。 由于这样的进气口表现出无法用单个传感器表征的湍流和高能量流场,因此需要许多传感器体来完全表征环境。 可以在复杂的自然通道中进行多传感器鱼体的类似部署,以描述其声场和流体动力场。 这些数据与鱼行为相关联,目的是开发从这些进水危险区域转移鱼类的方法,或吸引他们进入水旁路入口系统。
