Publication number: 20240363854Abstract: Methods of preparing metal-sulfide particles, such as for use in lithium-ion capacitors may include preparing a precursor solution. The precursor solution may include a copper-containing precursor and a metal-containing precursor. The methods may include mixing the precursor solution with water to form an aqueous precursor solution. The methods may include adding a sulfur-containing precursor to the aqueous precursor solution to form a sulfur-containing aqueous precursor solution. The methods may include heating the sulfur-containing aqueous precursor solution. The methods may include recovering a precipitate from the sulfur-containing aqueous precursor solution. The precipitate may be or include metal-sulfide particles.Type: ApplicationFiled: July 15, 2022Publication date: October 31, 2024Inventors: Daniel CHOI, Abhishek Chandrakant LOKHANDE

Patent number: 12089387Abstract: A device and method for absorbing electromagnetic waves can include a honeycomb sheet formed by a plurality of interconnected hexagon cells arranged in rows. The hexagon cells are made up of sidewalls, each sidewall formed by two surfaces that converge at a top of the sidewall and diverge from the top to a bottom of the sidewall such that a thickness of the sidewalls increases from top to bottom and an angle forms between the two surfaces at the top of the sidewall. In an example, the angle is about 8 degrees. The honeycomb sheet can be coated with a magnetic, composite coating to increase electromagnetic shielding. An example coating includes magnetic multi-granular nanoclusters (MGNC) and multi-walled carbon nanotubes (MWCNT). A base layer can be attached to the honeycomb sheet for mechanical stability and additional absorption. The device is suitable for radar absorbing materials (RAM) for aerospace and military applications.Type: GrantFiled: August 3, 2021Date of Patent: September 10, 2024Assignees: Khalifa University of Science and Technology, Korea University Research and Business FoundationInventors: Daniel Choi, Hammad Younes, Ru Li, Young Keun Kim

Publication number: 20240282019Abstract: In some aspects, the disclosure is directed to methods and systems for generating an augmented reality environment. An application executing on a computing device may receive a real-time video feed. The application may present the real-time video feed on a display of the computing device. The application may identify an image on a physical token from the real-time video feed. The application may select an animation from a set of one or more animations based on the identified image. The application may add the animation to the real-time video feed at an animation position above the physical token. The application may present the real-time video feed with the added animation.Type: ApplicationFiled: May 1, 2024Publication date: August 22, 2024Applicant: SEQUOIA GAMES, INC.Inventor: Daniel CHOI

Publication number: 20240184804Abstract: In some aspects, the disclosure is directed to methods and systems for secure and authenticated tracking of entity possession via a lightweight centralized or distributed ledger. Ownership records of different entities may be recorded on an immutable ledger such that provenance of the entities is verifiable and a user cannot create or counterfeit an entity. In some implementations, the system may store metadata of entities in a separate database that may store records for each entity and correspond to the respective entity's virtual identifier, enabling the ledger records to contain much less data, saving memory resources and the energy that is required to maintain the ledger. In some implementations, distributed incremental values may be provided to members of an ownership or possession chain of an entity, which may encourage compliance, reporting of ownership transfer, and encourage additional transfers.Type: ApplicationFiled: December 18, 2023Publication date: June 6, 2024Applicant: Sequoia Games, Inc.Inventor: Daniel Choi

Patent number: 11938013Abstract: An obscuring cover for covering at least a portion of a saw that includes a saw body and a saw blade attached to the saw body is provided. The obscuring cover includes an interior cavity defined by at least one inner surface of the obscuring cover. The interior cavity is configured to removably receive at least a portion of the saw body. At least one securing member is at least partially located at least one of internal to and adjacent to the interior cavity. The at least one securing member is configured to removably engage an exterior portion of the saw to removably connect the obscuring cover to the saw. At least a portion of the obscuring cover is configured to at least partially visually obstruct a subject's view of the saw blade when the obscuring cover is connected to the saw.Type: GrantFiled: February 8, 2022Date of Patent: March 26, 2024Assignee: MEDSTAR HEALTH, INC.Inventors: Andrew Curley, Nicholas Jarboe, Daniel Choi
