Abstract: A computer-implemented method for determining the location of a wireless device includes dividing an area into a grid and assigning the wireless device to a first portion of the grid. The method continues with calculating a first difference between a signal strength expected when the wireless device is at the first portion of the grid and a measured signal strength and assigning the wireless device to a second portion of the grid. The method also includes calculating a second difference between a signal strength expected when the wireless device at a second portion of the grid and a second measured signal strength and concludes with selecting the least one of the first and second differences to determine the location of the wireless device.

Abstract: A computer-implemented method for predicting signal coverage in a wireless network environment includes segmenting the wireless network environment into a plurality of zones, in which each one of a plurality of wireless communications devices operating in the wireless network environment is assigned to a corresponding one of the plurality of zones. The method continues with determining that a dependency exists between at least two signal reference relations from at least two of the plurality of zones and merging the at least two of the plurality of zones. The method concludes with adjusting the search space size for the optimal solution that predicts the signal coverage for the wireless network environment and locating at least one wireless access point within the wireless network environment based on the optimal solution.

Abstract: An adhesive composition substantially free of formaldehyde, comprising at least one bio-derived component, at least one multivalent cation and at least one polymer having a crosslinkable group, wherein the polymer having at least one crosslinkable group is substantially free of epichlorohydrin.

Abstract: A composition and process for formulating a size and for sizing and desizing textiles using an inorganic compound are provided. One inorganic compound that may be used is basic aluminum chloride. The use of basic aluminum chloride in a size formulation creates a size that is less environmentally hazardous but effective as a size.

Abstract: A method for increasing heat dissipation from the smolder or open flame site of an upholstered article by interposing a fire barrier material between the outer upholstery fabric and the filler or padding materials. The fire barrier material is formed by coating a fibrous substance, such as glass fibers, carbon fibers, and the like with a latex containing a finely divided heat conductive metal.

Abstract: A breathable fire barrier fabric comprising a fiber glass fabric on which is coated an encapsulating coating that minimizes or eliminates fiber to fiber self abrasion and effectively adheres to the glass fabric even when subjected to heat and flames; said fire barrier fabric having a porosity value at an acceptable level such that the fire barrier fabric inhibits the spread of fire. The invention contemplates a coating and method of applying same for glass fiber fabrics that can mechanically protect the glass from self-destruction without contributing to the fuel value of the fabric while maintaining a breathable fabric.
