Abstract: A method, system and computer program product for creating a report on the basis of a plurality of remote datasets. The system for achieving this includes an intelligence server, connected to one or more tree servers. The tree servers are in turn connected to one or more databases. A user specifies a report to be created by the system. A client, acting on behalf of the user, creates a report definition that is sent to the intelligence server and the tree servers. Each tree server creates one or more segments, or slices, of the report, using the information that resides on the tree server. These slices are then sent to the intelligence server, which aggregates the slices into a tree structure. The tree structure is then converted into a report for presentation to the client. Moreover, the intelligence server receives updates from the tree servers as necessary. To do so, the tree servers and the intelligence server remain in communication for the purposes of passing update messages.

Abstract: A brush with a compartment containing one or more single-use size roll or rolls of auxiliary or emergency toilet tissue. The compartment protects the roll or rolls from ordinary damaging forces such as wear, dirt and moisture.

Abstract: A method and apparatus are provided for constructing, operating, and marketing a vehicle that is alternatively adaptable for controlled, powered operation on the ground as an all-terrain vehicle (ATV), or in the air as a powered parachute, or for controlled, powered operation on both the ground and in the air as a flying ATV. On the ground, the vehicle is configured for controlled, powered operation over both smooth and rough terrain, as a true all-terrain vehicle.

Abstract: A resilient, impact-resistant, one-piece ballast apparatus is useful to provide external weight and stability for portable barricades and signs. The ballast is a solid, compression molded rubber device having a predetermined weight and design features including thickness, shape, perimeter contour and holes that permit the ballast device to be easily handled, quickly and securely affixed to or removed from barricade and sign structures, and stored for transport or between uses. The flat surface of the ballast permits application of identifying indicia of ownership that prevents loss and promotes reuse with resultant savings of economy and resources.

Abstract: The present invention provides a method and apparatus for high-speed autofocus and tilt of an inspection surface in a microscope system. The method and apparatus herein described projects an array of spots, lines, circles, grids or other shapes on the surface to be adjusted. The superposition of the array on the surface is imaged by a CCD camera and captured for subsequent analysis. Analysis of the captured image determines both the distance and angle through which the surface must be adjusted to bring it into the focal plane of the optical system. Focus and tilt error is estimated by comparing image dilation and distortion with calibrated data.

Abstract: A radiator (10) with molded plastic header tanks (14,18) has an electric coolant pump and housing assembly (20) integrally formed with the outlet header tank (18). A first half (24) of the pump housing is integrally molded into the header tank (18) and a low point and across a smooth and wide transition. The second half of the pump housing (26) mates at a sealed circular seam to the first half, with an electric coolant pump (28) held closely inside the two. No fasteners are needed to mount the pump, and the assembly minimizes parts and potential leak points.

Abstract: The present invention provides a method and apparatus for high precision image metrology. A feature dimension from the image is determined by measuring corresponding features in the Fourier power spectrum of the image with substantially improved precision due to immunity from noise and system response. Operationally, a digital image of the sample is acquired at sufficient resolution to capture the feature of interest. A sample widow is chosen which substantially isolates the feature of interest. The feature window is then piecewise extended to a predetermined window size for effective Fourier Transform interpolation. A Fourier Power Spectrum of the sample widow is generated at high sample density such that the loci of extremal points indicative of a feature dimension is identified with high precision. The relative spacing of the extremal points is measured and related to the desired feature dimension.

Abstract: A method and device to generate behavior for emulated visitors traversing an internet web site. The visitors may display behavior that is indistinguishable from those of actual users, a subset of the actual users, or the behavior may be purely hypothetical, such as when a visitor acts without evidence of having made an intentional choice. The invention tracks the actions of the visitors and develops reference distributions that may be compared to a site's usage distributions as obtained from actual visitors to the site. The reference distributions are then used to implement statistical estimation methods that measure relative information content. The invention comprises a general implementation and a deterministic implementation. The general version may be applied to live production web sites, and the deterministic version is best suited to offline processing.

Abstract: A method and apparatus that allows association rules defining URL-URL relationships, and URL-URL relationships that are strongly influenced by a web site's topology, to be identified and respectively qualified. Superfluous association rules may be separated from non-topology affected association rules and discounted as desired. The invention may be implemented in conjunction with a probalistic generative method used to model a web site and simulate the behavior of a visitor traversing the site. The invention further allows randomized web site visitor behavior to be separated into “interesting” and “uninteresting” behavior.

Abstract: A sealed, modular downhole antenna for measuring electrical characteristics of wellbore fluids and formations. An antenna includes a thin-walled curved metal tube, which houses coil of a length of conductive wire. The wire may be insulated by an insulating coating, as well as a filler that resides in the tube. The tube includes a coupling gap, to facilitate coupling electromagnetic energy through the tube, to and from the conductive wire. The tube also has a wall opening, for ends of the wire to attach to an adapter-connector. The adapter-connector includes suitable features for modular connection to an electrical cable, electrical connectors, or other electrical equipment. Features of the invention may be provided to ensure that such connection is resistive to the high pressures that are often encountered downhole. In this respect, the tube may be also coated with a sealant layer, to hermetically seal the tube, coupling gap, and junction between the adapter-connector and the tube.

Abstract: A metal nitride oxide semiconductor device capable of use within a memory cell, having a more heavily doped region of the same type as the substrate provided directly under the channel of the depletion mode device. Application of a positive write voltage to the gate of the device, with the substrate at 0 volts potential and the source and drain biased to a suitable positive level, results in avalanche operation of the device whereby charge is stored in a nitride oxide interface under the gate, thereby converting the device to enhancement mode operation. The charge can be removed with the source and drain biased to the 0 volt potential of the substrate and a positive erase signal applied to the gate. A four device memory cell is disclosed.
