    Abstract: A soil-based coupon having an electronically readable verification code printed thereon is used for verification of soil removal by a cleaning process. The coupon includes a soil overlay covering the verification code. The verification code is at least partially revealed by removal of all or part of the soil overlay during the cleaning process. If the data encoded in the verification code can be correctly decoded after completion of the cleaning process, the cleaning process can be verified. The soil overlay can be designed to match the application. The coupons may be used in a cleaning process verification procedure in which one or more computing devices analyze images of the verification codes to determine whether or not cleaning processes can be verified.

    Abstract: Disclosed herein are systems and methods for measuring one or more target analyte concentrations, particularly peroxyacid compounds, in a process solution, for example, in industrial and commercial water. These systems and methods include automated methods to measure the target analyte concentration in the process solution. The methods have the advantage of providing a large dynamic range for measurement and can be used in a wider range of process solutions.

    Abstract: An antimicrobial lighting system is used to reduce microbial growth on surfaces in or on air conditioning and/or heating equipment. In some examples, antimicrobial light within one or more antimicrobial wavelength ranges is applied to inactivate one or more microorganisms on target surface(s) within or on a packaged terminal air conditioner (PTAC). The antimicrobial light may include light within a first antimicrobial wavelength range and/or light within a second antimicrobial wavelength range. The antimicrobial lighting system may include an array of individually controllable antimicrobial light segments. An array controller may individually control activation of the one or more antimicrobial light segments based on the status information or commands received from a PTAC controller or from an external computing device.

    Abstract: A dilute chemical solution may be prepared in response to a dispense request by combining multiple concentrated chemicals with a diluent. In one example, a target amount of diluent is dispensed into a container until a measured weight of the diluent reaches a target weight. A first concentrated chemical is also dispensed into the container until a measured weight of the first concentrated chemical reaches a target weight. The liquid solution containing the diluent and the first concentrated chemical is withdrawn from the container and applied on a second concentrated chemical that is a solid state product so as to cause the second concentrated chemical to at least partially dissolve and enter the container. In some applications, the first and second concentrated chemicals react with one another to generate an active molecule in the chemical solution that is not present in either of the two concentrated chemicals.

    Abstract: A system and method for performing automated titrations. An automatic titrator utilizes control devices and sensors adapted for various chemical reactions to perform titrations and determine the content of a desired component of a solution. Batch and continuous mode titrations are possible. Titrant is added to a sample either in varying amounts or rates and a titration endpoint is observed via sensors. Control devices detect when the titration endpoint occurs and calculates the desired content. Various reactions within the solution may be suppressed in order to titrate isolated components individually.
