  • Patent number: 10926952
    Abstract: Techniques for identifying optimal placement instructions for placing an object within a container by a robotic device are disclosed. An artificial intelligence model may be trained utilizing historical placement images and/or placement data to identify subsequent placement instructions for a robotic device. As an object is brought within a threshold distance of a goal placement location, one or more images may be captured of an area adjacent to the placement location. Features of these images may be provided to the artificial intelligence model as input to cause the artificial intelligence model to identify particular placement instructions for the robotic device. By executing the identified placement instructions, the available space within the storage container may be optimized (e.g., increased) by reducing the space between objects of the storage container in accordance with the placement instructions.

  • Patent number: 10695442
    Abstract: A synthetic gene delivery platform with a dense surface coating of hydrophilic and neutrally charged PEG, capable of rapid diffusion and widespread distribution in brain tissue, and highly effective gene delivery to target cells therein has been developed. Nanoparticles including nucleic acids, are formed of a blend of biocompatible hydrophilic cationic polymers and they hydrophilic cationic polymer conjugated to hydrophilic neutrally charged polymers such as polyethylene glycol. The nanoparticles are coated with polyethylene glycol at a density that imparts a near neutral charge and optimizes rapid diffusion through the brain parenchyma. Methods of treating a disease or disorder of the brain including administering a therapeutically effective amount of nanoparticles densely coated with polyethylene glycol are also provided.

  • Patent number: 10632080
    Abstract: Improved distribution can be achieved by delivering nanoparticles possessing non-adhesive surfaces via CED in a hyperosmolar infusate solution. This delivery strategy minimizes the hindrances imposed by the brain extracellular matrix and reduces the concentration of therapeutic that is confined within perivascular spaces.
