Title: Object persistence in a database store
Inventor: VENKATESH RAMACHANDRAN
IPC: G06F7/00
Filed: 2004-07-29
Abstract: A new persistence format (404) for storing objects of a user defined type in a database store enables information about the structure of the type to be communicated to the store. This information enables a number of store optimizations, including direct structural access (408) to members of the type. Specifically, metadata is exchanged between the type implementer and the data store. The store uses the metadata to determine the storage layout for instances of the type. With this information, the store is able to detect access patterns that can be optimized to directly operate over the storage representation without hydration the object (410).

Title: Multi-layer fabric for papermaking machine
Inventor: MAJAURY BRIAN G
IPC: D21F1/00
Filed: 2003-12-15
Abstract: A fabric having top and bottom layers, with each layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven together. The fabric includes pairs of binder yarns that bind together the top and bottom layers. The binder pairs are interwoven so as to be an integral part of the first layer and contribute to a structure thereof. The binder pairs are a non-integral part of the second layer and do not contribute to d structure thereof. During a repeat pattern, at least one of the two binder yarns of a binder pair is integrally woven with the yarns of the first layer and passes over outer surfaces of, two non-consecutive yarns in the second layer. As a result, a "double knuckle" binding structure may be formed which improves integrity of the resulting composite fabric by reducing the length of the binder yarn path through the fabric.
