Patent number: 12221363Abstract: Smart membranes are integrated into a small, unmanned surface vessel to enable the efficient, automated cleanup of oil spills. Such a vessel has the potential to provide a low-cost, modular solution for day-to-day oil-spill cleanup operations, especially in confined aquatic areas (e.g., under piers or in the small spaces between marine vessels and piers). The membranes are provided on the surface of a conveyor belt that circulates the membranes through the surrounding body of water for oil collection, as well as through an internal reduction chamber of the vessel for oil release. The smart membranes are adapted to attract and repel oil in response to low-voltage commands applied across the conveyor belt, using a process that is repeatable for a number of cycles, offering high efficiency and long durability. Segments of the conveyor belt can be electrically isolated from one another to allow disparate electrical potentials to be imposed thereon.Type: GrantFiled: February 25, 2022Date of Patent: February 11, 2025Assignee: The Trustees of the Stevens Institute of TechnologyInventors: Eui-Hyeok Yang, Ronald Besser, Jian Xu, Wei Xu, Brendan Englot, Chang-Hwan Choi

Publication number: 20240424482Abstract: A green-engineered mulch product and methods for making same are disclosed. The mulch product includes a coating of aluminum-based water treatment residuals which makes the product “green.” Furthermore, coating aluminum-based water treatment residuals on mulch eliminates the problem of the low hydraulic conductivity of aluminum-based water treatment presiduals and makes it feasible to utilize its pollutant removal potential without requiring any modification to existing best management practices or additional maintenance.Type: ApplicationFiled: October 11, 2022Publication date: December 26, 2024Applicant: The Trustees of the Stevens Institute of TechnologyInventors: Dibyendu Sarkar, Viravid Na Nagara, Rupali Datta

Publication number: 20240389857Abstract: A minimally invasive device, containing a pressure channel, camera, and optical fiber imaging probe, to measure the stiffness of tissues in vivo and ex vivo is disclosed. The device is inserted into a patient and navigated to a tissue of interest, where stiffness is evaluated by applying suction and measuring the elongation or by applying compression force and measuring the compression of the tissue. Biopsies can be taken for further analysis, or tissue can be removed using an ablation laser. Small fluorescent molecules or therapeutics can also be delivered for improved visualization and targeted treatment. As such, this technology may be used to evaluate the stiffness of biomaterials as well as tissues and organs that are difficult to access, allowing for simultaneous diagnosis, treatment, and excision of diseased tissues.Type: ApplicationFiled: September 29, 2022Publication date: November 28, 2024Applicants: The Trustees of the Stevens Institute of Technology, Vanderbilt University, The Trustees of Columbia University in the City of New York, The Board of Trustees of the Leland Stanford Junior UniversityInventors: Jinho Kim, Gordana Vunjak-NovaKovic, John D.

Publication number: 20240318345Abstract: A process includes means for depositing an anti-corrosion coating filled with liquid oil on an aluminum substrate. Aluminum is anodized and then treated with a thin hydrophobic sub-coating. The pores created through anodization are then impregnated with liquid oil. Oil penetration is maximized and residual air is minimized by first filling the pores with a filling solution, replacing the filling solution with an exchange fluid, and then replacing the exchange fluid with perfluorinated oil. The oil gives the surface coating anti-wetting properties and self-healing properties, thereby protecting the aluminum substrate underneath from corrosion.Type: ApplicationFiled: June 5, 2024Publication date: September 26, 2024Applicant: The Trustees of The Stevens Institute of TechnologyInventors: Chang-Hwan Choi, Junghoon Lee

Patent number: 12058234Abstract: A system may provide blockchain-based storage node control for unified proof-of-storage interaction for off-chain data chunk storage. The system may include verification circuitry that may provide a challenge to a storage node to audit the storage status of a data chunk. The verification circuitry may obtain identities for the storage node and data chunk based on blockchain records. The verification circuitry may obtain a challenge answer from the storage node in response. The verification circuitry may analyze the challenge answer in view of a challenge key to confirm whether the storage node has possession of the data chunk. When the storage node has possession of the data chunk chain circuitry may add a verification record to the blockchain.Type: GrantFiled: March 27, 2020Date of Patent: August 6, 2024Assignees: Accenture Global Solutions Limited, The Trustees of the Stevens Institute of TechnologyInventors: Giuseppe Ateniese, Giuseppe Giordano, Luca Schiatti, Abdoulaye Faye, Andrea Maria Milazzo, Danilo Francati, Angelo Massimo Perillo

Patent number: 11968298Abstract: The present invention relates to methods for secure computation and/or communication. Entangled photons (118) are generated such that each participating party receives a series of optical pulses. Each party has private information (110, 112) which are never transmitted through public or private communication channels. Instead, each party converts their respective private information (110, 112) into measurement bases via an encryption process (114, 116) which are then applied to the entangled photons (118). After the measurement process, e.g., quantum frequency conversion (122, 124), reference indices are announced (124, 126) so that computation can be performed (128) without revealing the private information directly or indirectly.Type: GrantFiled: June 6, 2023Date of Patent: April 23, 2024Assignee: The Trustees of the Stevens Institute of TechnologyInventors: Yuping Huang, Lac Thi Thanh Nguyen
