Patent number: 11766366Abstract: Absorbent articles with biodegradable and/or biocompostable elements are disclosed, wherein the absorbent articles include sensors. The sensors detect and determine variables associated with collected fluids, solids, and gases, including a presence of fluids, solids, and gases, a volume of fluids, solids, and gases, and/or a distribution of fluids, solids, and gases. In one embodiment, the sensors and/or connected computing systems are calibrated to capacities and other properties of elements within the articles, including superabsorbent polymers, and are operable to trigger an alert based on detected or determined conditions.Type: GrantFiled: October 2, 2020Date of Patent: September 26, 2023Assignee: TETHIS, INC.Inventors: Ryan Nicholas Chan, Gordon Sidney Cox, Vladimiro Nettel, James Clayton Robinson, Robin Weitkamp

Publication number: 20210290452Abstract: A system for treating used hygienic articles including soiled or swollen superabsorbent materials (SAMs). The portion of the article including the soiled or swollen SAM is treated with a chemical which restructures or degrades the soiled or swollen SAM so that the products of the reaction are easily disposable in a method alternative to trash disposal and landfilling, including through municipal treatment where the products of the reaction do not clog a standard toilet or standard plumbing. Hygienic articles include baby diapers, adult diapers, incontinence pads, menstrual pads, or any other article which includes one or more SAMs.Type: ApplicationFiled: March 17, 2021Publication date: September 23, 2021Applicant: Tethis, Inc.Inventors: Ryan Nicholas Chan, Gordon Sidney Cox, Hailey Katherine Davis, Rachel Laura Preston, Robin Weitkamp, Kimberly Weitkamp
