Abstract: An information handling system includes a printed circuit board, a screw, and a processor. The printed circuit board includes a through hole via. The through hole via includes top and bottom sections plated with a conductive plating material, and a middle section without any conductive plating material. The screw in physical communication with the top, middle, and bottom sections of the through hole via in the printed circuit board. The processor determines whether an electrical circuit is formed between the screw, the top section of the through hole via, and the bottom section of the through hole via. Based on the determination of the electrical circuit being formed, the processor provides an indication that no intrusion has been made into the information handling system.

Abstract: A system for radiographic tissue density evaluation includes a cassette for exposure to an X-ray source, where the cassette is configured to obtain information to perform intensity standardization of a captured radiographic image of a subject, a calibration bar with a predetermined radiographic signature on or within the cassette to serve as reference for performing the intensity standardization, and a software program to perform analysis on and to provide a display of the captured radiographic image. The cassette also includes a radio-opaque backing with a spatial homogenous X-ray radiographic signature used to estimate a source-detector geometrical inhomogeneity.

Abstract: Systems and process are provided to make X-ray radiographs sufficiently quantitative and standardized for bone and other biological material or non-biologic material density evaluations. The X-ray radiograph methodology and system provide a cost effective diagnostic tool that may be used with existing X-ray radiography sources already present in many clinics and hospitals to ultimately produce large volumes of scientifically valid data and useful diagnostic and prognostic information. A calibration bar is added to a conventional X-ray film cartridge and images thereof subsequently incorporated into radiographs for interpretation or a cartridge is designed to integrate a calibration function. The calibration standard affords a standard against which material density is measured. A software program is provided to interpret tissue densities (including bone) to ultimately identify values compared to preselected thresholds.

Abstract: A lubrication apparatus is for a ball screw unit in which the grease state lubricant is used. There is formed a helical guide track in the lubrication apparatus. When the ball screw unit operates, a guide member rotates with the bolt, the grease stored in the guide track will flow ahead to the front terminal of the guide track and ooze out of the grease outlet to lubricate the bolt with the aid of a pressure produced due to the inertia of the flowing fluid, and the quantity of the oozed grease is determined by the size of the grease outlet. The lubrication of the ball screw unit can be performed automatically without relying on the external force.

Abstract: A screw-driven fan device includes a screw, a screw nut, a fan, and a connecting unit. An external edge of the screw has a rolling groove formed thereon and a groove formed alternately with the rolling groove. The screw nut, disposed on the screw, has a linking portion. The fan has a rotary axle with a hole formed thereon for screw passing through. The fan further has blades surrounding the rotary axle. The hole has a flange formed on an interior side thereof and engaged with the groove. The connecting unit has a space therein such that the fan can be placed in the space.

Abstract: A screw-driven fan device includes a screw, a screw nut, a fan, and a connecting unit. An external edge of the screw has a rolling groove formed thereon and a groove formed alternately with the rolling groove. The screw nut, disposed on the screw, has a linking portion located on one end of the screw nut. The fan has a rotary axle with a hole formed thereon for screw passing through. The fan further has blades surrounding the rotary axle. The hole has a flange formed on an interior side thereof, and the flange is engaged with the groove. When the screw rotates, the coordination of the flange and the groove causes the fan rotates simultaneously. The connecting unit has one side mounted on the linking portion of the screw nut. The connecting unit has a space therein such that the fan can be placed in the space, thereby the fan and the screw nut move together.

Abstract: A method and apparatus for dynamically generating code that generates a mapping between territories and territorial assignees is provided. A code generator uses the territory criteria to dynamically generate the code for an assignee-to-territory-mapping-engine. The generated code uses the territory criteria and the territorial assignees to produce an assignee-to-territory-mapping. The assignee-to-territory-mapping can be used to determine the sales representatives that are responsible for a particular territorial assignee.

Abstract: This invention is a method for reducing the total acid number of organic acid containing petroleum oil comprising forming a water-in-oil emulsion comprising an aqueous Group IIA metal hydroxide solution or slurry in a hydrocarbon oil, said water-in-oil emulsion having an aqueous droplet particle size diameter of from 1 to 25?, adding the water-in-oil emulsion to the organic acid containing petroleum oil and permitting the mixture to stand for a time sufficient to permit the neutralization of the organic acids in the petroleum oil.

Abstract: A sofa cover tailoring procedure includes the steps of (a) preparing a main cover cloth member and marking turning points of each curved lateral side of the main cover cloth with marks A;B;B1;C;D;E; b), (b) preparing two symmetrical side cover cloth members and marking turning points of the curved border line of each side cover cloth members with marks a;b;b1;c;d2;d1;e;f;g;h; and (c) stitching segment ABB1 of the main cover cloth member to segment abb1 of each side cover cloth member, then stitching segment B1C of the main cover cloth member to segment b1c of each side cover cloth member, and then stitching turning points d1 and d2 of each side cover cloth member together, and then stitching segment CD of the main cover cloth member to segment cd 1(d2) of each side cover cloth member, and then stitching segment DE of the main cover cloth member 10 to segment d1(de)e of each side cover cloth member, and then stitching segment gf of each side cover cloth member to segment gh of the respective side cover cloth m

Abstract: Aspects of the invention provide methods for rewriting and computing database queries that include outer join conditions, and for determining columns that satisfy a criteria. According to one aspect, a component relation key is assigned to each unique column in a first table and an aggregate relation key is generated for each record in a second table, wherein the aggregate relation key is based on one or more of the component relation keys corresponding to columns with non-null values from the second table. Distinct aggregate relation keys are determined, and an original query with an outer join is rewritten into at least a number of sub-queries equal to the number of distinct aggregate keys, wherein each sub-query includes a join condition based on each column represented by the respective distinct aggregate keys. Significantly, the combination of sub-queries is logically equivalent to the original query, but does not include outer join conditions. Therefore, a more efficient query is provided.
