摘要:
In the service architecture of the invention, each service is viewed as a hierarchical arrangement of service components. At least one management agent is associated with each layer, and is used to manage and preserve the expected performance of the service components. The management agents cooperatively exchange management information regarding the service components at their layers to permit service self-management and self-healing, enabling restoration and recovery with minimum or no human intervention.
摘要:
An architecture which permits externalized management of services includes a number of management service capability (MSC) definitions. Each operator may associate a management service capability with a Service/Service Capability for managing various aspects of the Service/Service Capability. An interface enables a variety of different management systems to utilize a common MSC structure, independent of the information models, transport mechanisms and management interface of the system using the MSC. With such an arrangement, management related integration costs associated with integrating and bundling complex multi-media services is significantly reduced.

A service tender node functions as an intermediary between subscribers and adjunct telecommunications services from multiple service providers to facilitate negotiation of services in real-time. The service tender node includes an index of services which is maintained and employed to search for applicable services in response to a tender request generated by a subscriber. Records in the index are described with an adaptive service definition which includes standard parameters and subjective parameters. The standard parameters identify types of service pursuant to telecommunications industry standards. The subjective parameters may be specified by individual service providers in order to differentiate their services within the service type defined by the standard parameters. Services generated from a search of the index pursuant to the standard parameters may be further sorted and filtered according to a comparison between a subscriber profile and the subjective parameters.

Network policies are managed based at least in-part on user/entity identity information with: a state monitor operable to monitor for state change events in user/entity state and related, network state or in traffic pattern and traffic flow state; an identity manager operable to obtain and validate user credentials; and a policy manager operable in response to a state change event detected by the state monitor (either the identity manager or a defense center) to select a policy based in-part on the user identity obtained by the identity manager or security context obtained by the defense center, and to prompt application of the selected policy. The policies are indicative of user/device authorization entitlements and restrictions to utilization of certain network resources, network services or applications. Dynamic policy selection and targeted responses can be used, for example, against a user who gains network access with stolen user ID and password, and subsequently attempts malicious behavior. In particular, the malicious behavior is detected and identified, and the malicious user can then be restricted from abusing network resources without adversely affecting other users, groups, network devices, and other network services.

The invention provides a composition comprising: (a) a star polymer comprising: (i) a core portion comprising a polyvalent (meth)acrylic monomer, oligomer or polymer thereof or a polyvalent divinyl non-acrylic monomer, oligomer or polymer thereof; and (ii) at least two arms of polymerized alkyl(meth)acrylate ester; and (b) an oil of lubricating viscosity, wherein the core portion further comprises a functional group of formula (I): —CH2—C(R1)(C(═O)A)-Y— (I) wherein R1 is hydrogen, a linear or branched alkyl group containing 1 to 5 carbon atoms; A is nitrogen or oxygen; and Y is a free radical leaving group selected from the group consisting of one or more atoms or groups of atoms which may be transferred by a radical mechanism under the polymerization conditions, a halogen, an —O—N═ group and an —S—C(═S)— group. The invention further provides the use of the composition in an oil of lubricating viscosity as a dispersant, a viscosity modifier or a precursor to a dispersant viscosity modifier.
摘要:
A system is provided including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor. The data received from the continuous analyte sensor may be used to provide alarms to the user when the analyte concentration and/or the rate of change of analyte concentration, as measured by the continuous analyte sensor, is above or below a predetermined range. Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. The device may provide for toggling between modes that allow or prevent the display of glucose concentration values associated with the continuous glucose sensor.

The invention provides a lubricating composition containing a copolymer comprising units derived from monomers (i) α-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof esterified and amidated with an alcohol and an aromatic amine respectively, and an oil of lubricating viscosity. The invention further relates to the use of the lubricating composition in an internal combustion engine.
摘要:
The invention provides a lubricating composition containing (a) 0.001 wt % to 15 wt % of a polymer with radial or star architecture; (b) an overbased detergent; (c) a dispersant; and (d) an oil of lubricating viscosity. The invention further provides a method for lubricating a mechanical device with the lubricating composition.
摘要:
A diabetes management system or process is provided herein that may be used to analyze and recognize patterns for a large number of blood glucose concentration measurements and other physiological parameters related to the glycemia of a patient. In particular, a method of monitoring glycemia in a patient may include storing a patient's data on a suitable device, such as, for example, a blood glucose meter. The patient's data may include blood glucose concentration measurements. The diabetes management system or process may be installed on, but is not limited to, a personal computer, an insulin pen, an insulin pump, or a glucose meter. The diabetes management system or process may identify a plurality of pattern types from the data including a testing/dosing pattern, a hypoglycemic pattern, a hyperglycemic pattern, a blood glucose variability pattern, and a comparative pattern. After identifying a particular pattern with the data management system or process, a warning message may be displayed on a screen of a personal computer or a glucose meter. Other messages can also be provided to ensure compliance of any prescribed diabetes regiments or to guide the patient in managing the patient's diabetes.
摘要:
The disclosed invention relates to lubricant or functional fluid compositions containing viscosity index improvers in the form of self-healing polymers. The polymers may comprise one or more cleavable linkages, such as one or more disulfide bonds and/or one or more diene/dienophile linkages, to permit the polymer to reform if cleaved during use.
