Abstract: A polishing wheel including a lower polishing surface and defining a different color from a secondary portion of the polishing wheel, so as to indicate wear of the polishing surface. The polishing surface includes a plurality of main radial flutes extending from a central passage to an outer edge. A reduced profile for the main radial flutes is provided adjacent to the outer edge. A plurality of secondary radial flutes is provided extending from the outer edge, but not in communication with either the central passage or the main radial flutes.

Abstract: A certificate and method is provided that reduces the likelihood of counterfeiting via photocopier by providing various features that would require the use of a color duplex copier in order to effectively copy the certificate. Requiring the use of a color duplex copier is an effective deterrent because the use of such a device significantly reduces the profit margins of counterfeiting efforts.

Abstract: The present invention is directed to techniques for determining a value of a cumulative datum during a selected time interval. The disclosed method and system for collecting contact center data includes a plurality of agent and work item queues and a workflow server for distributing work items to available agents; and an event processor, that, for a selected a base time interval for accumulating a cumulative datum, determines a the rolling window that is at least one of equal and greater than the base interval and being an integer multiple of the base interval, and, when the rolling window partly spans a prior base interval, the processor can determine a rolling average for the cumulative datum over the width of the rolling window and, when the roiling window partly spans a prior base interval, the processor can estimate a value for the cumulative datum in the partly spanned prior base interval.

Abstract: A method and a system for heating such as ground heating or curing concrete.

Abstract: An event reporting system includes a computational component 228 operable (a) to receive notification of a change to an attribute of an entity, the entity, prior to the change, being associated with a first surrogate key, and (b) to defer the use of a second surrogate key for the entity until a selected time. The second surrogate key was generated to reflect the change.

Abstract: In one embodiment, a data processing system includes a first database 304 maintained by a first party (such as a customer); a second database 324, 328 maintained by a second party (such as a vendor) different from the first party; a work queue 316 to specify data to be added to the second database; an extract, transform and load module 308 to write data from the first database to the work queue; and a data import module operable 320 to import data from the work queue to the second database. In the system, the first party is not privileged to write the data directly to the second database but is privileged to write the data to the work queue. The import module transforms the data written to the work queue to a form semantically compatible with the second database.

Abstract: Systems, methods, apparatus and software can be implemented to discover third-party copy devices in a distributed computing environment, determine which of the third-party copy devices is best suited for a particular data moving application, and thereby better utilize network and computing system resources. Moreover, environment changes (e.g., device failure, network traffic changes, new device addition) can be dynamically incorporated into the information used for third-party copy device discovery and selection. These systems, methods, apparatus and software help to reduce human errors which can cause failures in critical data protection operations.

Abstract: Color-stable, pigmented optical bodies comprising a single or multiple layer core having at least one layer of a thermoplastic polymer material. The thermoplastic polymer material has dispersed within it a particulate pigment. The optical bodies generally possess high clarity and low haze and exhibit a transmission of light within a wavelength band of interest within the visible spectrum of from about 10 to about 90 percent.

Abstract: A bone-repair composite includes a core and a sheath. The core is a first primary unit including a combination of a first set of yarns coated with a calcium phosphate mineral layer. The first set of yarns being made from a first group of one ore more polymers. The sheath is a second primary unit a combination of a second set of yarns or one or more polymer coatings. The second set of yarns being made from a second group of one or more polymers, wherein the composite is made by covering the core with the sheath, and the composite is compression molded to allow the sheath to bond to the core. The bone-repair composite has a bending modulus comparable to that of a mammalian bone, such that the ratio of the core to the sheath is provided to maximize the mechanical strength of the bone-repair composite to mimic the mammalian bone.

Abstract: A perpendicular magnetic recording data storage system combines a perpendicular medium that has a thin low-magnetic-permeability or “soft” underlayer (SUL) with a recording head that has a trailing shield (TS) with a thick throat height, i.e., a thickness in a direction orthogonal to the recording layer of the medium. The SUL is thin enough and has a low enough magnetic permeability to become saturated in a region beneath the trailing gap of the head during writing, but the throat height of the TS is thick enough to prevent the TS from becoming magnetically saturated during writing. The magnetic saturation of the SUL during writing changes the magnetic reluctance such that more of the magnetic flux going through the SUL changes direction (“field undershoot”) and goes to the TS. If the permeability of the SUL is so low (e.g.
