    • A measurement means for a downhole tool for determining the orientation of the axis of a downhole tool in relation to true north. It includes a gyro sensor capable of measuring angular rate, a rotation means for rotating the gyro sensor about a sensor axis, a measurement means to detect the angular rate at the gyro sensor as it is rotated to form a series of readings, and a processor capable of interpreting the signal amplitude from the series of readings and determining the points of greatest signal amplitude. The processor is also being capable of comparing the phase difference between the actual readings taken against what would be generated with the sensor pointing true north thus providing a downhole tool axis angular deviation from true north. The rotation means rotates the gyro sensor in discrete steps.
    • 井下工具的测量装置,用于确定井下工具相对于真北的轴线的取向。 它包括能够测量角速率的陀螺仪传感器,用于围绕传感器轴旋转陀螺传感器的旋转装置,用于检测陀螺仪传感器旋转以形成一系列读数时的角速率的测量装置,以及处理器 能够解读来自该系列读数的信号幅度并确定最大信号幅度的点。 处理器还能够比较实际读数之间的相位差与传感器指向真北部所产生的相位差,从而提供井下工具轴与真北的角度偏差。 旋转装置以离散步骤旋转陀螺传感器。

    • A method, system and article of manufacture for query processing and, more particularly, for managing execution of a query against data in a database. One embodiment comprises receiving a query having (i) at least one result field configured to return data from at least one data record included with the database, and (ii) a query condition comprising a field and a query object associated with the field by an operator configured to select values for the field from the query object. The method further comprises determining whether the query object is configured to provide one or more valid values for the field. If the query object is not configured to provide one or more valid values for the field, the query object is transformed into a transformed query object that is configured to provide one or more valid values for the field. Then, the query is executed against the database.
    • 用于查询处理的方法,系统和制品,更具体地,用于管理对数据库中的数据的查询执行。 一个实施例包括接收具有(i)至少一个结果字段的查询,所述结果字段被配置为从包含在数据库中的至少一个数据记录返回数据,以及(ii)查询条件,其包括通过字段与字段相关联的字段和查询对象 操作员配置为从查询对象中选择字段的值。 所述方法还包括确定所述查询对象是否被配置为为所述字段提供一个或多个有效值。 如果查询对象未配置为为该字段提供一个或多个有效值,则将查询对象转换为已配置为为该字段提供一个或多个有效值的转换查询对象。 然后,针对数据库执行查询。

    • A method, system and article of manufacture for data processing and more particularly for managing access to data in a database that should be available for a limited number of accesses. One embodiment provides a method comprising receiving, from a requesting entity, a query against a database having consumable data that is configured to be accessible for only a predefined number of accesses. The query is configured to access the consumable data and is executed against the database to obtain a query result that includes the consumable data. The method further comprises determining whether the predefined number of accesses is reached as a result of the execution of the query against the database. If so, the consumable data is made inaccessible. The obtained query result is returned to the requesting entity.
    • 一种用于数据处理的方法,系统和制品,更具体地涉及用于管理数据库中对于有限数量访问可用的数据的访问。 一个实施例提供了一种方法,包括从请求实体接收针对具有被配置为仅对预定数量的访问可访问的可消耗数据的数据库的查询。 该查询被配置为访问消耗品数据并针对数据库执行以获得包括消耗品数据的查询结果。 该方法还包括:作为对数据库执行查询的结果,确定是否达到预定数量的访问。 如果是这样,消耗品数据就无法访问。 获取的查询结果返回给请求实体。
