A floating insect canopy forms a canopy enclosure when floating on the water, such as a pool. The floating insect canopy has a float that extends around the canopy perimeter to form a floating base. The float material may be a foam that is configured in a float sleeve. The canopy may be a netting material that enables a person visibility through the canopy when floating on a raft inside the canopy enclosure. A floating insect canopy forms a generally dome type shape by the use of a flexible extensions configured within an extension sleeve. The extension sleeve retains the flexible extensions and causes the dome shaped canopy enclosure to be automatically formed and retained by the flexible extensions. A door panel may be formed in the canopy.

A netting material having a length dimension and a width dimension much smaller than the length dimension comprises a flap folded from a fold region of the netting material along a longitudinal fold line at a distance from a longitudinal edge of the netting. The flap therefore comprises at least two layers of the netting material folded together. One or more eyelets are provided in the flap.

An extruded thermoplastic product having a surface abrasive to insects. The extruded product is formed from a dry powder composition being comprised of a thermoplastic polymer, a plurality of pelletized diatomaceous earth, and a plurality of expandable microballoons. The composition is mixed and heated in an extrusion machine before being forced into a die of selected profile. Cooling the material immediately after being removed from the die allows the diatomaceous earth to remain at the surface of the material. The material with the surface abrasive to insects is used is used as a component in a product, such as conventional weatherization products, for placement in a building opening that insects use as ingress to the building. Products contemplated for use with the extrusion include door sweeps, door and window seals, and thresholds.

A method and apparatus for preventing the escape of hazardous materials from fluid flow control systems of the character used by municipalities for carrying runoff storm water away from streets and populated areas.

Devices, methods, and systems having insect guards in devices and systems for aspirated smoke, gas, or air quality monitoring are described herein. One aspirated smoke, gas, or air quality monitoring unit includes a detector module that includes at least one particulate sensing chamber within the detector module and an air inlet connecting the sampling tube to the particulate sensing chamber allowing communication of air from the sampling tube to the particulate sensing chamber; and a spiral shaped insect guard positioned within the inlet.

A detection chamber assembly of a smoke detector is provided. The detection chamber assembly includes upper and lower covers, louvers and a corrugated bug screen. The louvers are arranged with the upper and lower covers to define a chamber bound between the upper and lower covers and the louvers. The louvers include a first pair of louvers defining a first space therebetween to permit fluidic ingress to the chamber and a second pair of louvers defining a second space therebetween to permit fluidic ingress to the chamber. The second space is wider than the first space. The corrugated bug screen includes a body disposed about the louvers and a mesh corrugation feature coupled to the body at the second space to permit fluidic ingress to the chamber at the second space and to inhibit bug ingress to the chamber at the second space.
