Abstract: Computing devices may require disassembly to repair or replace a defective or damaged component, or to facilitate recycling at the end of the computing device's service life. While pressure sensitive adhesive (PSA) is good at creating secure connections between components within the expected operating conditions of the computing device, PSA resists intentional disassembly of such components. The presently disclosed PSA with thermally conductive release tabs provides a mechanism for effective spot-cooling of the PSA between adhered components. Once the PSA reaches a low temperature threshold, one component may be mechanically separated from another component. This yields potentially faster and easier disassembly of adhered components than prior art techniques.

Abstract: A multi-cell battery pack includes adjacent thin-film battery cells electrically coupled to one another with a conductive battery cell connection tab. The conductive battery cell connection tab is folded at a deflection point separating a first aperture in a first portion from a second aperture in a second portion. The first aperture and the second aperture are aligned with one another along an axis while the first portion and the second portion are positioned to rest adjacent to opposite surfaces of a first thin-film battery cell. In this position, the first portion and the second portion electrically couple a first thin-film battery cell to a second thin-film battery cell in a same battery cell stack.

Abstract: Included are polyurethaneurea compositions include polyurethaneurea aqueous dispersions. The dispersions may be prepared with solvent or in the absence of any added solvent. Films and other shaped articles may be prepared from the dispersions by a casting a drying method and optionally included with a substrate including paper, fabric or garments.

Abstract: The invention provides spandex having improved hysteresis and a method for making such spandex. The spandex of the invention comprises the polyurethaneurea reaction product of: (a) poly(tetramethylene ether) glycol (b) 1-isocyanato-4-[(4-isocyanatophenyl)methyl]benzene wherein the mole ratio of diisocyanate to glycol is from about 1.52 to about 2.04; and (c) a mixture of chain extenders comprising: from about 35 to about 55 mole percent ethylene diamine; and from about 45 to about 65 mole percent 1,2-propanediamine.

Abstract: The present invention relates to an electroluminescent illumination system, more particularly to an electroluminescent light system that allows vehicles to be visible during periods of low light, for example bicycles. The EL panels can be selective affixed to any of the bicycle frame members or wheels, where the EL panels are electrically connected to the power source. The power source applies an AC signal to the conductive substrates of the EL panels resulting in the EL material charging and discharging to emitting light.
