摘要： A fuel assembly grid inspection apparatus includes a precision noncontact measurement device having a source of illumination and a viewing system which define an inspection field of view. The viewing system is adapted to view and record one or more images of an object, such as a fuel assembly grid, located in the field of view to provide information from actual measurements of the grid which can be calculated to determine whether or not it comes within acceptable tolerances of the measurements of a standard grid of the same design. The apparatus also includes a universal fixture adapted to support any one of a variety of grids of different designs within the field of view such that portions of the fixture within the field of view are substantially transparent to the viewing system. The viewing system and the fixture are movable relative to each other in X, Y and Z directions for achieving a complete inspection of all parts of the grid. Typically, the grid being inspected has at least a pair of vertically displaced fuel rod contacting dimples disposed in each of a plurality of cells defined in the grid. The dimples are inspected for perpendicularity with respect to each other by using the viewing system to view them at separate instances but from the same location within the field of view.

摘要翻译：燃料组装电网检查装置包括具有照明源的精密非接触测量装置和限定检查视野的观察系统。观察系统适于查看和记录位于视场中的物体（例如燃料组件网格）的一个或多个图像，以从网格的实际测量中提供信息，该信息可被计算以确定其是否到达在相同设计的标准网格的测量的可接受公差范围内。该装置还包括适于支撑视场内的不同设计的各种格栅中的任何一个的通用夹具，使得视野内的固定装置的部分对观察系统基本上是透明的。观察系统和固定装置可以在X，Y和X方向上相对移动，以便对电网的所有部分进行完整的检查。通常，被检查的网格具有至少一对垂直位移的燃料棒接触凹坑，设置在网格中限定的多个单元中的每一个中。通过使用观察系统在不同的实例处观察它们，但是在视场内的相同位置来检查凹坑的垂直度。

摘要： The address translation logic of the present invention is incorporated in a global positioning system (GPS) receiver and operates to group data in memory based on translating the address from a direct memory access controller. The data includes post-correlated samples of the correlation of a signal with a generated frequency and a generated code having a plurality of time offsets. In general, the address translation logic organizes the data such that each element of the data associated with particular ones of the plurality of time offsets are grouped together in order to improve the efficiency of performing a fast Fourier transform of the data. In addition, the address translation logic allows the transfer of data from correlation circuitry to memory, from the memory to an FFT module, and from the FFT module to the memory using standard DMA controllers.
摘要翻译：本发明的地址转换逻辑被结合在全球定位系统（GPS）接收机中，并且基于从直接存储器访问控制器转换地址来操作以将数据分组在存储器中。数据包括信号与产生的频率的相关性的后相关样本和具有多个时间偏移的生成代码。通常，地址转换逻辑组织数据，使得与多个时间偏移中的特定时间偏移相关联的数据的每个元素被分组在一起，以便提高执行数据的快速傅里叶变换的效率。此外，地址转换逻辑允许从相关电路向存储器传输数据，从存储器到FFT模块，以及使用标准DMA控制器从FFT模块传输到存储器。
