The compositions and methods according to the present disclosure provide several advantages, such as stability, less time to provide sufficient antimicrobial inactivation, and are inexpensive and require lower amount of active concentrations to be effective.

Abstract: The present disclosure provides a means to remove oxidative compounds such as free halogen and chloramines from a liquid, while also providing components with antimicrobial properties in order to combat biofouling and the shedding of pathogens into liquids. In particular, methods of removing an oxidative compound from a liquid in which the liquid is contacted with one or more polymeric beads. As described herein, the oxidative compound binds to the polymeric bead and is removed from the liquid.

Abstract: A method for determining a length of a span of electrically conductive material, comprising a first voltage measurement across the entire span, and a second voltage measurement across a constant-length segment of the span. The dual measurements allow the calculation of the span length in a manner that is robust to many disturbances including ambient temperature, material temperature, and material stress and fatigue.

Abstract: A braided, open structure composite made with large prepreg tow can be cured without bonding at the yarn crossovers and after removal from the mandrel, it can be used directly as a spring in which the spring constant in bending, torsion, tension or compression can be controlled by the geometry of the braided structure as well as the size of the structural elements. Alternatively the spring may be curved in multiple directions to form complex shapes and then crossovers can be re-bonded to make more rigid open structure composites that would be difficult or impractical to manufacture by conventional techniques.

Abstract: A retrieving device includes a body with at least one respiratory passageway formed in it through which a dog can breathe when holding the device in its mouth during retrieval. In some embodiments, the body includes two radially-large end sections that are harder for dogs to grasp with their mouths, two radially-midsize lateral sections positioned therebeween each defining lateral respiratory passageways for side-breathing by the dog, and a radially-narrow middle section positioned therebeween defining a forward/transverse respiratory passageway for front-breathing by the dog. In use, the respiratory passageways decrease obstructions to enable the dog to breathe more freely to avoid overheating and associated problems. In addition, one or more flotation elements can be provided in the body so provide buoyancy for the retrieving device in the event it's launched into water during retrieving activities.

Abstract: A retrieving device includes a body with at least one respiratory passageway formed in it through which a dog can breathe when holding the device in its mouth during retrieval. In some embodiments, the body is hollow and in the form of a shell defining an internal cavity that functions as a lateral respiratory passageway, with communicating respiratory passageways formed through the shell. In other embodiments, the body is solid with internal respiratory passageways formed through it. And in still other embodiments, the body has surface features (e.g., grooves or other thinned portions) that function as external respiratory passageways. In use, the respiratory passageways decrease obstructions to enable the dog to breathe more freely to avoid overheating and associated problems. In addition, one or more flotation elements can be provided in the body so provide buoyancy for the retrieving device in the event it's launched into water during retrieving activities.

Abstract: An electro-optical-mechanical tether is presented. The tether is designed to be strong and lightweight, and to transmit both optical signals and electricity. The proposed use relates to airborne devices, in which the tether may transmit electrical power to or from the device as well as enabling communications between the device and the ground. This tether may also be ideal for other aerospace applications and for connections between ships.

Abstract: N-halaminehydantoinyl epoxide compounds which can be used for the construction of coatings and materials which can be rendered biocidal by exposure to halogen solutions either before or after curing the coating or material are disclosed. The biocidal coatings and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring such as mildew. The coatings are compatible with a variety of substrates including, but not limited to, cellulose, chitin, chitosan, synthetic fibers, cement grout, latex caulk, acrylic films, polyurethanes, plastics and paints.
