Filed: 1998-06-04
Abstract: A method and apparatus for managing at least part of a communications network and particularly for managing a customer network, for example, within an asynchronous transfer mode communications network. A predictor is used to predict parameters such as bandwidth levels and to predict when the parameter(s) will exceed capacity or previously agreed thresholds. These agreed levels may be specified for example in a service level agreement between a service provider and a customer. The predictor also predicts, how much excess there will be and how long this will occur for. This information is provided to the service provider/customer and also can be provided to an agent which comprises a computer system. This agent negotiates on behalf of either the customer (for example) with another agent acting on behalf of the service provider (for example) and in this way new terms for an agreement between the two parties is obtained.

Title: Process and formulation for improved texture and melt of reduced-fat cheese product
Inventor: ZAIKOS WILLIAM JOHN
IPC: A23C19/086
Filed: 1998-06-15
Abstract: The invention generally relates to a reduced-fat cheese product and a method for producing such product. More specifically, this invention relates to reduced-fat, low-fat or fat-free natural shredded cheese products that do not exhibit the characteristics of stickiness and rapid skin formation upon melting which are normally associated with such cheeses. The cheese product of the invention, which has very low levels of fat, provides the taste and mouthfeel associated with full-fat cheeses. The fat content of shredded cheese is minimized by first producing an essentially fat-free natural cheese product and then applying a small amount of fat to the surface of the cheese in its shredded form. The amount of fat added can be controlled according to whether a reduced-fat, low-fat, or fat-free cheese is desired.

Title: Method and apparatus to isolate a formation zone
Inventor: WILLAUER DARRIN L
IPC: E21B33/124
Filed: 1997-10-24
Abstract: A method and apparatus are disclosed which allow isolation of a plurality of zones for treatment particularly sand fracturing. The lowermost barrier can be pumped through tubing (12) and anchored in cased or open holes. In the preferred embodiment, the pumped plug (20) has a visco-elastic member (74) which contains a particulate aggregate mixture (87), such as described in U.S. Patent 5,417 285. The visco-elastic material is subjected to a force which change its shape in that the material obstructs the wellbore. The shape change also accomplishes dehydration of the material within the visco-elastic enclosure by virtue of fluid displacement, resulting from a volume reduction, hardening it so that a plug using the visco-elastic material is formed. Thereafter, a packer (14) on the rubing string (12) is set to isolate the zone for sand fracturing. The process can be repeated without tripping out of the bole as additional plugs are pumped through tubing and the process is prepared. At the conclusion of the fracturing, the various plugs, which are of simple and economical construction, can be readily milled out

Title: Optical layer quasi-centralized restoration
Inventor: DOVERSPIKE ROBERT DUNCAN
IPC: H04L12/56
Filed: 1999-02-17
Abstract: A wavelength-switching, mesh-based restoration method among a network of optical cross-connects (OXCs) (10) is disclosed. The method is defined as "quasi-centralized" in that the network is first partitioned into a plurality of subnetworks (30,40), then a single "restoration controller" (22) is defined for each separate subnetwork. The subnetwork partitioning is defined as being either "minimally overlapping", meaning that the OXCs are "clustered" in their network topology, with only a few links required to join the various, autonomous subnetworks, or "highly overlapping", meaning that the OXCs are defined as being included in more than one subnetwork. Each subnetwork restoration controller (SRC) includes a network graph and is therefore responsible for providing restoration around faults recognized in its own subnetwork.
