Apparatus and associated methods relate to constructing a resource and attribute tasking solution to complete a user's objective with resource and attribute characteristics defining the tasked objects, in response to receiving a task definition, and satisfying a task definition constraint. An object includes of a set of resource and attribute dimensions each of which have a set of possible values. A tasking solution is the union of all valid solution vectors in the dimension space. The solution identifies all valid values to present to a user or other agent to make further decisions on further constraining resource and attribute characteristics for a final materializable tasking. In an illustrative example, the objective may be mapping resource supply to task demand. The task demand may be, for example, delivering a database-as-a-service platform configured based on rules generated to satisfy task definition capacity constraints. In some examples, the resource supply may include computing and communication resources configurable to provide access to the platform via a network cloud. Exemplary platforms delivered at different times may be configured with different resources and attributes, based on constructing a tasking solution determined from the available resource supply as a function of time. Various examples may advantageously provide optimized on-demand tasking solutions, configuring a user's available resource supply to complete the user's objective while satisfying task definition constraints.

Rule generation and tasking resources and attributes to objects system and method

Use of release fluids or agents constituting hyperbranched polymers. The three-dimensional structure imparts characteristics that make the hyperbranched polymers useful in xerographic processes. The hyperbranched polymer release fluids or agents may be used with a fuser member having a substrate, an outer layer covering the substrate, and a release coating on the outer layer, wherein the release coating includes a hyperbranched polymer.

Release fluid compositions

A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorinated copolymer surfactant to form a coating solution, and b) providing said coating solution on said fuser member to form a fuser member coating, wherein said fluorinated copolymer surfactant comprises a fluorinated acrylate copolymer having pendant fluorinated alkyl groups.

A fuser debris inhibiting system and apparatus using an impregnated cleaning web. This web is impregnated with materials of: succinic acid, DPTA, HEDTA, NTA, DMSA or their salts. The web can contact the fuser member directly or can contact external heat rolls which in turn contact the fuser roll. The delivery of these materials to the surface of the fuser member substantially inhibits the formation of contaminants thereon.
