  • Publication number: 20240098051
    Abstract: Various embodiments include systems, methods, and non-transitory computer-readable media for sharing and managing media galleries. Consistent with these embodiments, a method includes receiving a request from a first device to share a media gallery that includes a user avatar; generating metadata associated with the media gallery; generating a message associated with the media gallery, the message at least including the media gallery identifier and the identifier of the user avatar; and transmitting the message to a second device of the recipient user.

  • Patent number: 11918977
    Abstract: Contaminate-sequestering coatings including a network of hydrolyzed silane compounds including a plurality of thiol functional groups, a plurality of fluorinated functionalities, or both are provided. The contaminate-sequestering coatings may sequester one or more per- and polyfluoroalkyl substances (PFAS), heavy metals, biological species or any combination thereof. Methods of functionalizing a substrate surface with contaminate-sequestering functionalities that sequester one or more PFAS, heavy metals, or both are also provided. Methods of removing contaminants from contaminate-containing liquids, and devices including the contaminate-sequestering coatings are also provided.

  • Patent number: 6671539
    Abstract: A method of forming a surgical splint to receive a patient's dentition and thereby align the upper jaw and the lower jaw during surgery includes generating a CT computer model of bone structure, generating a digital dental computer model of the patient's dentition, and then combining the CT computer model and the digital dental computer model to form a composite computer model. The composite computer model may be displayed, and at least one of the upper jaw and lower jaw repositioned relative to the patient's skull and the composite computer model to form a planned position computer model. Using this desired position computer model, a computer model surgical splint of the patient's dentition may be formed, which is then input into a fabrication machine to form a surgical splint. The method also includes forming and displaying the composite computer model. A workstation includes a CT machine, a digital scanner, a computer, an input command mechanism, a display, and a fabricating machine.
