  • Publication number: 20250069438
    Abstract: Embodiments pertain to a computer-implemented method of identifying at least one facial micro-expression pattern of a face of a subject by (1) receiving a plurality of images of the face of the subject, where the plurality of images represent consecutive images of the face of the subject taken sequentially during a period of time; (2) feeding the plurality of images into a machine-learning algorithm, where the machine-learning algorithm includes a diagonal micro attention (DMA) module that identifies at least one facial micro-movement between the plurality of images and correlates the facial micro-movement to at least one facial micro-expression pattern; and (3) outputting the facial micro-expression pattern of the face of the subject. Additional embodiments pertain to computing devices for identifying at least one facial micro-expression pattern of a face of a subject in accordance with the aforementioned processes.

  • Publication number: 20250026863
    Abstract: This invention relates generally to covalently crosslinked colloidal cellulose nanocrystals (xCNC) and methods of preparation and use thereof. The colloidal cellulose nanocrystals (CNCs) are covalently crosslinked in aqueous suspension to generate a network showing tunable physicochemical properties. The xCNC structures are tunable in terms of their physicochemical properties and arrangement within the hydrogel network. The covalent crosslinking of solitary sulfonated (—OSO3) CNCs can be accomplished without prior hydroxyl replacement or functionalization.

  • Publication number: 20240306636
    Abstract: This invention relates generally to cellulose nanocrystal-based emulsions that can serve as a spray adjuvant for improved agrochemical application efficiency. More particularly, the cellulose nanocrystal-based emulsions are nanocellulose-stabilized Pickering emulsions having a semi-liquid formulation of colloidal cellulose nanocrystals and biopolymers that can substitute currently used surfactants and drift reducing agents in agrochemicals. The cellulose nanocrystal-based emulsions are suitable with both water soluble and oil soluble active ingredient chemistries, and the shear characteristics of the emulsions make them suitable for oil in water-based spray applications. Droplet size distribution can be tuned by changing the ingredient concentrations, thus helping control particle drift. Moreover, a stable cross-linked network formation facilitates the entrapment and encapsulation of volatile agrochemical chemistries, thus preventing their volatilization and reducing vapor drift.

  • Patent number: 11975486
    Abstract: The present invention provides a swarm manufacturing platform, based on a swarm 3D printing and assembly (SPA) platform as a model for future smart factories, consisting of thousands of IoT-based mobile robots performing different manufacturing operations with different end effectors (e.g., material deposition, energy deposition, pick and place, removal of materials, screw driving, etc.) and real-time monitoring. The swarm manufacturing platform transforms a 1-D factory into a 2-D factory with manufacturing robots that can move across the 2-D factory floor, work cooperatively with each other on the same production jobs, and re-configure in real-time (i.e., the manufacturing robots can be digitally controlled to move, re-group, calibrate, and work on a new job in real-time).
