  • Publication number: 20240074894
    Abstract: A container-closure system includes a container configured to hold a therapeutic liquid and having a dispensing tip configured to dispense a dose of the therapeutic liquid. A vented cap is configured to fit over at least a portion of the container including the dispensing tip and having one or more vents that allow air to pass into and out of a cavity defined between the vented cap and the dispensing tip. A second cap is configured to fit over at least a portion of the vented cap. A tamper evident seal is coupled to the second cap and one or both of the container and the vented cap.

  • Publication number: 20230266766
    Abstract: The present disclosure provides a model for semantic navigation for service robots to find out-of-view objects in an indoor environment. Initially, the system receives a target object to be reached by the mobile robot in the indoor environment. Further, a current location of the mobile robot is identified by a localization technique. An embedding corresponding to each of a plurality of visible regions is computed using a pretrained Graph Neural Network GNN. The GNN is pretrained using a trajectory data and a spatial relationship graph associated with the indoor environment. Further, a similarity score is computed for each of the plurality of visible regions based on the corresponding embedding using a scoring technique. An optimal visible region is identified by comparing the similarity score. Finally, a next action to be taken by the mobile robot selected from a plurality of actions based on the optimal visible region.

  • Publication number: 20230112661
    Abstract: Multilayer metallo-dielectric energy control coatings are disclosed in which one or more layers are formed from a hydrogenated metal nitride dielectric, which may be hydrogenated during or after dielectric deposition. Properties of the multilayer coating may be configured by appropriately tuning the hydrogen concentration (and/or the spatial profile thereof) in one or more hydrogenated metal nitride dielectric layers. One or more metal layers of the multilayer coating may be formed on a hydrogenated nitride dielectric layer, thereby facilitating adhesion of the metal with a low percolation threshold and enabling the formation of thin metal layers that exhibit substantial transparency in the visible spectrum. Optical properties of the coating may be tuned through modulation of metal-dielectric interface roughness and dispersion of metal nanoparticles in the dielectric layer.

  • Publication number: 20230080342
    Abstract: In state of the art methods for object goal navigation, scene understanding is implicit in their goal oriented exploration policies. Implicit scene understanding coupled with navigation is shown to be specific to tasks for which training is done and not generalizable to new tasks. Thus, embodiments of present disclosure propose a method of goal-conditioned exploration wherein scene understanding is decoupled from the exploration policies. Here, the scene understanding required for navigation is provided by a region classification network that is trained using semantic graphs representing the scene and agent can be navigated towards the goal either by using any state of the art pure exploration policies or by traversing through potential sub-goals identified based on a Co-occurrence Likelihood score calculated by using predictions from the region classification network. Hence, the method of present disclosure can be easily generalized to new tasks and new environments.
