    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 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: Systems for quantifying one or more target analyte concentrations in a process solution are provided and can be used, for example, in methods for quantifying a target analyte concentration. These systems and methods include continuous and batchwise automated titration methods that use titration chemistries to measure the target analyte concentration in the process solution using a multiwavelength detector. The methods provide for efficient and robust automated titration methods for a variety of target analytes and can include methods that analyze more than one analyte and that provide for a dynamic range for measurement of more than one target analyte concentration.

    Abstract: An apparatus and method for configuring product packaging and removal of the packaging from a product is disclosed. The labeled product packaging includes a shrink wrap packaging adapted for sealing around a product. A predefined point of failure is configured in the packaging and includes a failure mode for when pulled in at least one direction. A label is sealed to the packaging and adhered to the predefined point of failure in covering relation over the predefined point of failure. Lifting the label from the packaging tears open the packaging starting at the predefined point of failure so the product can be removed from the packaging.
