Publication number: 20240078486Abstract: Example methods and systems are directed to a managed inventory. A database may store information regarding items owned by a user. The information regarding an item may include a quantity owned and one or more triggering events. Based on the occurrence of a triggering event, an order for the item may be placed without user intervention. Data to the database may be provided by one or more sensors. Triggering events may be defined in terms of sensor data. The triggering event may be defined by a user or through machine learning. The order may be placed using a predetermined modality or a dynamically-determined modality based on one or more criteria, such as price, shipping speed, and the urgency of the order.Type: ApplicationFiled: November 9, 2023Publication date: March 7, 2024Inventors: Dane Glasgow, Steve Yankovich, Marc Peter Hosein, Shweta Pogde, Snigdha Mokkapati, Gokulkrishna B. Pillai, Sri Harsha Chevuru, Dinesh Kumar Damodharan, Chethan Narayan, Vinay Rajashekar Nagar, Suraj Chhetri

Publication number: 20230113398Abstract: A flow battery includes a positive electrode, a positive electrode electrolyte, a negative electrode, a negative electrode electrolyte, and a polymer electrolyte membrane interposed between the positive electrode and the negative electrode. The positive electrode electrolyte includes water and a first redox couple. The first redox couple includes a first organic compound which includes a first moiety in conjugation with a second moiety. The first organic compound is reduced during discharge while during charging the reduction product of the first organic compound is oxidized to the first organic compound. The negative electrode electrolyte includes water and a second redox couple. The second couple includes a second organic compound including a first moiety in conjugation with a second moiety. The reduction product of the second organic compound is oxidized to the second organic compound during discharge.Type: ApplicationFiled: November 22, 2022Publication date: April 13, 2023Inventors: SRI NARAYAN, SURYA G.K.
