Publication number: 20170160255Abstract: An optical chemical test system and method detects information from areas of a chemical test component in the field of view of a color camera. The chemical test component can be a card or a strip and has a color change test area that changes in appearance when subjected to a target chemical in solution, which changes are detected by the color camera and used by an electronic control device to calculate a concentration value for the target chemical. Other areas of the chemical test component, when provided, calibrate the concentration value by providing further data that is recognized by the color camera and used by the electronic control device for calibration. The chemical test component can include features such as one or more indicia or locations for optical coding, card or strip identifiers and authenticators, one or more reference color areas and one or more reference white areas.Type: ApplicationFiled: December 2, 2015Publication date: June 8, 2017Applicant: Sani-Hawk Optical Solutions LLCInventors: Brian Ehlert, David A.

Patent number: 9575087Abstract: Single-use, pre-sterilized, and pre-calibrated, pre-validated sensors are provided. These sensors are designed to store sensor-specific information, such as calibration and production information, in a non-volatile memory chip on the sensor or in a barcode printed on the sensor. These sensors may be utilized with in-line systems, closed fluid circuits, bioprocessing systems, or systems which require an aseptic environment while avoiding or reducing cleaning procedures and quality assurance variances. The sensors exhibit both their primary sensing function such as conductivity, pH level, dissolved oxygen, pressure or temperature, as well as at least one secondary sensing function of risk management or risk mitigation.Type: GrantFiled: August 12, 2013Date of Patent: February 21, 2017Assignee: Parker-Hannifin CorporationInventors: Karl G.
