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: Experimental color data obtained from a plurality of cleaning process verification coupons is used to determine optimized cleaning process parameters in an automated cleaning machine. Color data may also be obtained from cleaning process verification coupon(s) to verify the efficacy of a real-world cleaning processes in an automated cleaning machine and/or to obtain one or more suggested corrective action(s) in the event the cleaning process yields an unsatisfactory cleaning result. Based on the optimized cleaning process parameters, an automated cleaning machine may automatically adjust one or more cleaning process parameters to correct for non-optimized parameters sensed during execution of a cleaning process to help prevent an unsatisfactory cleaning result.

Abstract: Image classification is used to dynamically control one or more wash parameters in an automated cleaning machine. An imaging device installed in the wash chamber of the cleaning machine captures one or more image(s) of articles to be cleaned at various times throughout a cleaning process. A computing device analyzes the captured image(s) to classify the images as to an article type and a rack volume. Based on the article type classification and the rack volume, the computing device dynamically controls one or more parameters of the cleaning process to achieve a satisfactory cleaning and/or sanitizing result.
