Title: Novel thermoplastic or thermoset pipes including conductive textile reinforcements for heating and leak detection purposes
Inventor: BACON JEFFERY E
IPC: F16L53/38
Filed: 2001-05-21
Abstract: Novel thermoplastic pipes which can withstand internally generated and/or applied pressures for utilization within, primarily, underground liquid and gas transport systems are provided. Such pipes are improvements over standard metal pipes due to construction costs, shipping costs, implementation costs, flexibility to compensate for underground movements, non-rusting characteristics, reduced crack propagation possibilities, and ease in manufacture. Such pipes are preferably reinforced with specific textile reinforcement materials that permit a lower thickness of plastic to be utilized than is generally required to withstand high pressure situations and also serve to prevent propagation of any cracks which may develop within the thermoplastic or thermoset materials. Such pipes exhibit an elongation at break in relation to that provided by the textile reinforcement and not with regard to the same type of elongation at break characteristic for the thermoplastic or thermoset composition. Furthermore, a leakage or burst detection system and a heating method to ensure non-freezing of transported materials within such pipes is also contemplated within this invention.

Title: Relocating pages that are pinned in a buffer pool in a database system
Inventor: SACHEDINA AAMER
IPC: G06F12/12
Filed: 2003-02-26
Abstract: A system and method for directing a database management system to relocate buffer pages that are pinned in a buffer pool in a data processing system.  Each of the buffer pages have a respective page descriptor for indicating the location of the buffer page in the buffer pool. Once the pages are relocated, the now free system memory of the buffer pool is resized. Prior to resizing, a selected pinned page is latched by an agent of the system, wherein the selected page of the buffer pages is in a resize region of the buffer pool. The pinned and latched page thereby becomes a fixed page. The agent for the database management system, such as a determinator module, also determines a suitable relocation region of the buffer pool for the fixed page, and a resizer module coupled to the determinator module copies the contents of the fixed page to the relocation region and changes the respective page descriptor to indicate the relocation region. The resizer module performs the relocation for other pages in the resize region to allow dynamic resizing of the buffer pool, while maintaining the presence of pinned versions of the pages in the buffer pool prior to resizing.

Filed: 2001-11-20
Abstract: First and second recursive space-time trellis coded modulation (STTCM) coders each produce, in successive symbol intervals, a plurality of T M-PSK symbols from a group of b input bits, where M=2b. The groups of b bits are supplied directly to the first coder and via an interleaver to the second coder, whose output symbols are conversely de-interleaved. A selector supplies T symbols from the first coder and T symbols from the de-interleaver alternately in successive symbol intervals to T output paths for T antennas providing transmit diversity. STTCM codes are described for different values of T and M  and for fast and slow fading channels.
