    • In combination with a tractor and a trailer, an apparatus and method are provided for monitoring various operating conditions of at least the trailer by a driver positioned on the tractor. The apparatus preferably has a pneumatic braking system carried by the tractor and the trailer to permit the driver to supply pneumatic braking pressure from the tractor to the trailer. The pneumatic braking system preferably includes at least one pair of air hoses connected to the tractor and the trailer and a coupler connected to the pair of air hoses. The coupler has interconnecting first and second coupler portions arranged to facilitate connecting and disconnecting the pair of air hoses. The apparatus also has a data communications system which preferably includes a respective pair of transceivers connected to the first and second coupler portions for communicating signals representative of monitoring data from the trailer to the tractor so as to in turn be monitored by a driver positioned on the tractor.
    • 与拖拉机和拖车一起提供了一种装置和方法,用于通过位于拖拉机上的驾驶员来监测至少拖车的各种操作条件。 该装置优选地具有由拖拉机和拖车承载的气动制动系统,以允许驾驶员从拖拉机向拖车提供气动制动压力。 气动制动系统优选地包括连接到拖拉机和拖车的至少一对空气软管和连接到该对气管的联接器。 联接器具有互连的第一和第二联接器部分,其布置成便于连接和断开该对气管。 该装置还具有数据通信系统,其优选地包括连接到第一和第二耦合器部分的相应的一对收发器,用于将代表监视数据的信号从拖车传送到拖拉机,从而进一步由位于 拖拉机。

    • Methods and computer-readable media are provided for performing a search on a relational database. According to one method, a query class is provided that includes properties that specify how a query is to be performed and how results from the query are to be returned, and an execute method that is called to perform the actual query. A keyword query class derived from the query class is also provided that includes keyword query properties and an execute method for performing the keyword query. In order to perform a keyword query of an SQL database, an instance of the keyword query class is created, the properties set on the instance, and the execute method called. When the execute method is called, the specified properties are translated into an equivalent SQL statement and the search is performed on the identified relational database by a search service.
    • 提供了用于在关系数据库上执行搜索的方法和计算机可读介质。 根据一种方法,提供了一个查询类,其包括指定如何执行查询以及如何返回查询的结果的属性以及被调用以执行实际查询的execute方法。 还提供了从查询类派生的关键字查询类,其中包括关键字查询属性和执行关键字查询的执行方法。 为了执行SQL数据库的关键字查询,将创建关键字查询类的实例,实例上设置的属性以及调用的execute方法。 当调用execute方法时,将指定的属性转换为等效的SQL语句,并通过搜索服务在标识的关系数据库上执行搜索。
