Title: Method and system for estimating gas production by a landfill or other subsurface source
Inventor: TANG JINSHAN
IPC: G01V11/00
Filed: 2002-12-11
Abstract: A useful method and system for estimating LFG generation and gas permeability in a landfill or other subsurface-gas producing body of material is provided.  The gas generation rate in a portion of a landfill or other subsurface-gas producing body of material is estimated by obtaining a time history record of atmospheric pressure that is representative of atmospheric pressure at a surface boundary of the portion of the landfill or the subsurface gas producing body of material, measuring the gas pressure at least at one selected location at the landfill (or subsurface body) site over a time period that is included in the time history record, and using the atmospheric pressure and the measured gas pressure over the time period to estimate LFG  generation rate and gas permeability of the portion of the landfill or the subsurface gas producing body of material. In a preferred embodiment, gas pressure is measured at a plurality of selected locations within the refuse portion of a landfill, and in the case of an unlined landfill in the supporting soil below the landfill, and the measured pressures are used to estimate LFG generation rate and gas permeability of the landfill.

Title: Method of using flash memory for storing metering data
Inventor: SIMMONS STEPHEN M
IPC: G06F12/16
Filed: 2003-04-22
Abstract: A metering data preservation and storage methodology, including steps for protecting data during periods in which power is lost to the meter, is provided. In particular, a methodology for using nonvolatile flash memory structures is used in association with various volatile memory structures for the storage and preservation of metering data acquired from a solid-state utility meter. The methodology includes the use of the volatile memory structures for the temporary storage (146) and alteration (148) of the measured and calculated metering data so as to avoid an effective reduction in the lifespan of the non-volatile memory structure which can only be written, erased and rewritten to a finite number of times. Further, such usage reduces costs associated with the maintenance and incorporation of such memory types in the meter. The methodology further includes the use of the non-volatile flash memory (126) as a permanent storage medium for the acquired metering data during power loss (124) to the meter.

Title: Torsionally de-coupled engine mount system
Inventor: MILDENSTEIN STEPHEN E
IPC: F02C7/36
Filed: 2002-09-17
Abstract: A torsionally de-coupled engine mount system (13) for use in tilt rotor aircraft (11) applications is disclosed, in which an engine is mounted at it s forward end to a prop rotor gear box by means of a forward mount (303) that is a simple adapter fitting, and at its aft end to a pylon assembly by an aft mount (305) that is a simple bi-pod fitting. The forward mount (303) counteracts forces and moments in six degrees of freedom, but the aft mount (305) only counteracts lateral and vertical loads. The contribution from the engine to the overall dynamic response of the aircraft is tuned by selective ly tailoring the size, shape, weight, and material of the forward mount (303). The engine mount system torsionally de-couples the engines from the prop rotors, thereby preventing rotor torque from being induced into the engines. In addition, the contribution from the engines to the overall dynamic respon se of the aircraft can be tuned by selectively tailoring the size, shape, weigh t, and material of the forward mounts between the engines and the transmissions .

Title: Method and apparatus for pre-emptively arbitrating on an acyclic directed graph
Inventor: OPRESCU FLORIN
IPC: G06F15/16
Filed: 1993-12-16
Abstract: A bus arbitration scheme is implemented in a system where an arbitrary assembly of nodes on a system bus have been resolved into an acyclic directed graph. The hierarchical arrangement of nodes has one node designated a root while all other nodes have established parent-child relationships with the nodes to which they are linked.      Each node may have a plurality of connected child ports with a predetermined acknowledgment priority scheme established. Fair bus access arbitration provides for bus granting in a sequence corresponding to the predetermined port priorities allowing all nodes a turn on the bus. The root node may always assert its priority access status to gain bus access which is useful for accommodating a root node which requires isochronous data transfer.  Alternatively, a token passing arbitration scheme may be implemented where the token for bus access is passed around the nodes according to the above-described predetermined port priority scheme. Preemptive bus initialization may be triggered by any node upon detection of a necessitating error or addition or removal of a connection to an existing node.

Filed: 2005-06-06
Abstract: This invention relates to the Pattern Recognition )PR) of noisy/inexact strings and sequences and particularly to syntactic Pattern Recognition. The present invention present s a process by which a user can recognize an unknown sting X, which is an element of a finite, but possibly larger Dictionary, H, by processing the information contained in its noisy/inexact version, Y, where Y is assumed to contain substitution, insertion or deletion errors. The recognized string, which is the best estimate X+ of X, is defined as that element of H which minimizes t he Generalized Levenshtein Distance D(X,Y) between X and Y, for all X < H. Rather than evaluate D(X,Y) for every X < H sequentially, the present invention achieves this simultaneou sly for every X < H by representing the Dictionary as a Trie, and searching the Trie using a new AI - based search strategy.
