Abstract: Disclosed are apparatus and methodology subject matters for upgrading firmware associated with one or more metrology devices and adjunct devices. Methods are disclosed for broadcast transmission of portions of a firmware image file from an originating device over a network connecting multiple devices to be upgraded. The entire image file may be transmitted as segments to be assembled by the end devices. Broadcast segments not properly received from the originating device may be retried directly from the originating device or from neighbors correctly receiving the segment. A viral propagation methodology is disclosed as an alternative to portions of the broadcast methodology.

Abstract: Disclosed are apparatus and methodology subject matters for providing an interface between a meter in an advanced metering system and an application running on such a system. The interface operates effectively as a device driver to translate communication protocols so that plug-n-play functionality (interchangeability) may be provided for meters provided from various venders in an open operational framework, such as for ANSI standard C12.22 meters. The interface provides a plug-in based library that interfaces between the user interface and a data collection engine that is designed to optimize data collection functionality. Optimization is achieved, at least in part, by providing data request processing separately from response processing. Separate response processing allows for the possibility of unsolicited messages being processed for later association with other possible jobs.

Abstract: A method of fabricating a fuel assembly grid that includes providing a plurality of interconnected straps that form a lattice pattern, wherein the lattice pattern of the straps defines a plurality of cells, providing a sleeve that has a cylindrical portion and a flared portion, and inserting the sleeve into at least one of the cells. When inserted, at least a portion of the cylindrical portion of the sleeve will reside inside the cell and the flared portion will extend above the top end of the cell and overhang the perimeter of the cell. The flared portion is melted and flows over and fuses to the straps that define the cell. The straps may include weld tabs over which the melted material flows and to which it fuses. The melting and fusing steps also preferably cause any loose straps surrounding the cell to become attached to the sleeve.
