Abstract: A toxic material detecting device includes an outer casing and a toxic material retaining composition within the casing. The toxic material detecting device can detect the presence of radioactive, chemical, biological, and toxic materials in air, gases, oils, soil, and water that contact one or more detection chambers within the device. The toxic material retaining composition can retain the toxic material within the device for a period of time sufficient for detection, thereby providing increased sensitivity for the device.

Abstract: The solar illumination distribution system (10) uses a series of parabolic reflectors (12, 14, 42, 44, 46) and other optical components to direct and distribute solar radiation onto a desired surface (G), such as for illuminating a stadium or arena as well as providing light for the growth of natural turf in desired locations within the stadium or arena. A primary parabolic reflector (12) and a secondary parabolic reflector (14) focus solar radiation onto one end of a fiber optic bundle (24), which transmits the solar radiation to a desired location. At the desired location, the light transmitted through the fiber optic bundle (24) is distributed through a plurality of fiber optic cables (36, 38, 40) to a plurality of tertiary parabolic reflectors (42, 44, 46) to illuminate the desired surface (G).

Abstract: The nanoparticle purifying system includes a container having an interior portion including a plurality of aluminum plates. Each of the plurality of aluminum plates includes a solid filtering agent, such as activated charcoal and, optionally, sodium tetra borate. The container can further include an inlet for receiving polluted air, an outlet for discharging purified air, and a pathway extending between the plurality of aluminum plates from the inlet to the outlet. The nanoparticle purifying system includes a removable lid for disposing on the container. Each of the plurality of aluminum plates can include an adhesive, such as hot glue and/or carpet glue, for attaching the solid filtering agent to the surfaces of the plurality of aluminum plates and interior surfaces of the container.
