Abstract:

Various modified carbon products are disclosed which can form a part of a polymeric product containing the modified carbon product and a polymer. One type of modified carbon product disclosed is a carbon product having attached at least one organic group, monomeric group, or polymeric group. Another type of modified carbon product disclosed is a carbon product having attached a group having the formula: âArâCO âR or âC H CO âR where R is an organic group, monomeric group, or a polymeric group. The third type of modified carbon product contains a) a carbon product having attached at least one organic group directly attached to the carbon product, b) at least one ionic group, ionizable group, or a mixture thereof attached to the organic group, and c) at least one counter-ionic group or counter-ionizable group with at least one organic group, monomeric group, or polymeric group, or mixture thereof, where the counter-ionic or counter-ionizable group is attached to the ionic and/or ionizable group. A method of improving the dispersion of carbon products in polymers is also disclosed which involves dispersing the modified carbon products described above in a polymer to form a polymeric product.

US Classification:

428372, 428364, 428394, 428395

Abstract:

Methods of making polymeric fibers are provided and include spinning a solution containing at least one polymer, a modified pigment having attached at least one organic group, and a solvent. The polarity of the solvent and the polarity of the modified pigment are selected such that the polymer is soluble in the solution and the modified pigment is maintained dispersed throughout the solution. The polarity of the modified pigment may be substantially the same as the polarity of the solvent. Fibers of acrylic-containing polymers and other polymeric fibers are also provided. Articles and reinforcing material containing the various fiber(s) are also described.

International Classification:

US Classification:

705 7, 705 1, 705 2, 705 35

Abstract:

System and method for preparing, using, and displaying a state model of a process, as an industrial or business process, as a sequence of discrete steps. The state model defines the behavior of the logical objects making up a process model of the process as (1) a set of permitted states and (2) a set of permitted transitions between the permitted states. The state model is created by selecting a template for the state model, and selecting industrial or business object components for the state model (for example, by using âOOPâ methods or other programming paradigms). The user then selects or defines state transitions for the state model, for example, by defining permitted state transitions from a âfrom stateâ to a âto stateâ. The defined or selected state transition rules are identified to State Transition Rule names. That is, state transitions are associated to specific state transition rules, names, and conditions, and the state transition names and state transition rule names are enumerated.

International Classification:

G06Q 30/00

US Classification:

705 26

Abstract:

A dynamic pricing system and method that enables prices for sellable objects to be dynamically adjusted using pricing factors corresponding to attributes of the sellable objects. Product administrators are enabled to define sellable products and extended attributes for the products, while pricing administrators are enabled to define price lists for the sellable products and extended attributes. Sales representatives build sellable objects, such as quotes, orders, shopping carts, etc, by adding products that customers would like to purchase to the sellable object. Additionally, extended attributes may be selected for all or a portion of the products. Using Static Pricing, an initial or static price is determined for the sellable objects. The static price may then be dynamically adjusted prior to or at the point of a sales transaction or offer using pricing factors corresponding to combinations of various attributes of the sellable object and/or products from which it is built.

Abstract:

A system and method of analyzing a power grid in an integrated circuit includes inputting a circuit design to a test bench, inputting a plurality of initial values for the circuit design in to the test bench, setting a current time t to 0 value for an initial time (t) of the operation of the circuit design, representing each capacitor in an RC circuit corresponding to the power grid circuit design by the each capacitor's respective time variant equivalent companion model, describing each one of the plurality of RC equivalent circuits mathematically as one of a corresponding plurality of linear equations, storing the plurality of linear equations in a matrix Yfor time t, resolving the matrix Yto determine a DC operating point, updating the RC equivalent circuits and the corresponding plurality of linear equations at a second time step t=t+h where h is a time step value equal to the current time t and a next simulated operation time, storing the updated plurality of linear equations in a matrix Yfor time t, inverting the matrix Yto form inverted matrix Y, resolving the inverted matrix Y, calculating a new time step and setting the current time t to t+h, comparing the new time step h to a plurality of time steps in a time step database, selecting one of the plurality of time steps substantially equal to the new time step and recalling a solution corresponding to the selected time step.

Abstract:

A charger unit includes: a housing, prongs for engaging an electrical outlet, the prongs being coupled to one another by a cross-member and being movable relative to the housing between a retracted position in which the prongs are received in the housing and an extended position in which the prongs protrude from the housing, the prongs being biased toward the extended position, a locking arm comprising a first end, a cut out for receiving the cross-member when the prongs are in the retracted position and a second end for abutting the cross-member when the prongs are in the extended position, the first end of the locking arm being coupled to a carriage and the cutout being provided between the first end and the second end, the locking arm being movable by the carriage into and out of engagement with the cross-member and the locking arm being biased toward the passage.

US Classification:

Abstract:

An extended attribute-based pricing system and method that enables users to build sellable objects based on selected products and extended attributes for those products. Product administrators are enabled to define sellable products and extended attributes for the products, while pricing administrators are enabled to define price lists for the sellable products and extended attributes. Sales representatives build sellable objects, such as quotes, orders, shopping carts, etc, by adding products that customers would like to purchase to the sellable object. Additionally, extended attributes may be selected for all or a portion of the products. The extended attributes may be stored in attribute classes, and may be loaded into memory structures to reduce database accesses.
