| 20090025308 | Seismic support and reinforcement systems - The present invention includes a set of reinforcement and support devices for existing or new roof, ceiling and/or floor systems together with numerous variations that may be installed into existing buildings or new buildings to help prevent separation of wood or metal roof, ceiling and/or floor systems from the concrete, masonry or other types of walls supporting these systems in commercial, industrial and/or residential buildings. One embodiment includes a set of three brackets that are installed in a triangularly shaped arrangement along a side of a primary support beam and to the wall underneath a ledger, thus anchoring the support beam to the wall of the structure and stabilizing the roof, ceiling or floor it supports. Another embodiment includes a single integrated unit that attaches to the wall underneath the ledger and to an adjacent support board, thus anchoring the support board (and the system it supports) to the wall of the structure. Another embodiment includes an angle iron with predrilled holes that attaches through the ledger directly to the wall to reinforce the ledger and extend the area of horizontal support provided by the ledger. Other embodiments provide support structures that may be attached and arranged to provide specific structural support at designated locations, and/or to provide wall-to-wall structural support across the span of a roof, ceiling or floor. All embodiments may be adapted for use with ceilings, roofs or floors. | 01-29-2009 |

| 20080248578 | Detection of explosives and other species - The present invention provides a series of systems, devices, and methods relating to the determination of explosives, such as peroxides or peroxide precursors, and other species. Embodiments of the invention may allow a sample suspected of containing an explosive (e.g., a peroxide) or other species to interact with a reactant, wherein the sample may react and cause light emission from the reactant. Advantages of the present invention may include the simplification of devices for determination of peroxide-based explosives, wherein the devices are portable and, in some cases, disposable. Other advantages may include relative ease of fabrication and operation. | 10-09-2008 |
| 20100213451 | EMISSIVE POLYMERS AND DEVICES INCORPORATING THESE POLYMERS - The present invention relates to a class of luminescent and conductive polymer compositions having chromophores, and particularly solid films of these compositions exhibiting increased luminescent lifetimes, quantum yields and amplified emissions. These desirable properties can be provided through polymers having rigid groups designed to prevent polymer reorganization, aggregation or π-stacking upon solidification. These polymers can also display an unusually high stability with respect to solvent and heat exposures. The invention also relates to a sensor and a method for sensing an analyte through the luminescent and conductive properties of these polymers. Analytes can be sensed by activation of a chromophore at a polymer surface. Analytes include aromatics, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state. The present invention also relates to devices and methods for amplifying emissions by incorporating a polymer having an energy migration pathway and/or providing the polymer as a block co-polymer or as a multi-layer. | 08-26-2010 |
