Abstract: A method of measuring an environmental contaminant includes the steps of dividing a target environment into a plurality of spaces, placing a monitor in each space, uploading device data from each monitor, and processing the device data to determine a level of environmental contamination within each space. Each monitor is configured to measure a level of an environmental contaminant within the space for a sample period. A radon monitor includes a radon sensor configured to detect radon decay events, an environmental sensor configured to measure an ambient condition of air surrounding the radon sensor, a processor configured to record device data including a count of a number of radon decay events and the ambient conditions, and a communication means for transmitting the device data. A system includes a plurality of monitors, a receiving device for receive device data from each monitor, and a cloud computer to process the device data.

Abstract: In one embodiment, a disinfectant composition includes a peroxide, a peracid, an anionic surfactant, a nonionic polymer, and one or both of a linear fatty alcohol and an alkyl pyrrolidone. The disinfectants provide greater killing rates for microbial populations in short periods of time, and therefore can be considered to be fast-acting disinfectants.

Abstract: A method is provided for the microbicidal treatment of a surface such as sanitization, disinfection, sterilization, and decontamination of a surface or object by use of an anti-microbial composition comprising an aqueous solution of peracetic acid and hydrogen peroxide with acetic acid, water soluble polymer containing lactam, and phosphate ester surfactant and little or no stabilizer, and according to the method enhanced microbicidal efficacy is obtained when the composition is applied onto a surface as a thin film wetting the surface so that a shorter contact time for a desired fractional reduction in microbial population is obtained Still further, the compositions comprise photosensitizer for light-activated anti-microbial efficacy.

Abstract: An antimicrobial composition comprising water, an organic acid such as citric acid, chitosan, and one or more heterocyclic N-halamine compounds such as MDMH and/or DMDMH.

Abstract: In one embodiment, a method for treating a textile with an antimicrobial composition includes preparing an antimicrobial composition that includes water, an organic acid, chitosan, and one or more heterocyclic N-halamine compounds, preparing an aqueous solution that comprises the antimicrobial composition, applying the aqueous solution to a textile, and heating the textile to cure the antimicrobial composition.

Abstract: An analytic method for the determination of the concentration of polysaccharide polymer in solution comprises the in-line derivatization of the polymer by reaction with sulfonate dye. The reaction results in an analyte-derivative, carried in a mobile phase, that can be detected and quantitatively determined by ultraviolet absorption or by fluorescence measurement. The method can provide sensitive and precise measurement in spite of limited solubility of the analyte.

Abstract: A method of deactivating chemical contaminants and biological agents from a target surface by and aerosol spraying the target surface with an electrostatically charged, photosensitizer solution, and then illuminating the surface with ultraviolet light.

Abstract: A microbicidal and decontaminant composition comprising an aqueous solution of peroxides and peracids having equilibrium reaction products, a photoreactive surfactant, and a polymer, wherein said polymer interacts with said peroxides and said peracids.

Abstract: A method and system for controlling a vehicle given to a third party. The system includes a system controller; a mode-indicating device coupled to the system controller; and an authenticator coupled to the system controller. Here, the system controller is adapted to communicate a driving restriction to the vehicle upon an activation of the mode-indicating device by an authorized driver and until a deactivation of the mode-indicating device by the authorized driver, the system controller is adapted to restrict the activation and the deactivation of the mode-indicating device unless the authorized driver has been authenticated by the authenticator, and the driving restriction includes a limit selected from the group consisting of a limit in number of starts, a limit in speed, a limit in acceleration, a limit in number of minutes, a limit in distance, a limit in gears, a limit in locations, and combinations thereof.

Abstract: An apparatus for spectroscopic evaluation of a subject's body fluids may be used at the interstitial region adjacent to or in between a subject's extremities using a spectroscopic probe. The spectroscopic probe may possess one or more of the movements such as rotational, translational, and/or vertical freedom necessary for the probe to contact the subject's tissue at a consistent angle and pressure while accommodating the different size of the subject's extremities, and may be housed in a device optimized for attaining reproducible blood flow to the region of the subject that is measured, and for minimizing the effects of the housing pulling, stretching, pressing, compressing the subject's skin. A pressure sensor may be used to ensure that measurements are taken at an optimal pressure. A touch sensor may be used to activate a system and/or to ensure flushness.
