  • Publication number: 20240112808
    Abstract: A computer-implemented method includes receiving, by a computing device, a particular textual description of a scene. The method also includes applying a neural network for text-to-image generation to generate an output image rendition of the scene, the neural network having been trained to cause two image renditions associated with a same textual description to attract each other and two image renditions associated with different textual descriptions to repel each other based on mutual information between a plurality of corresponding pairs, wherein the plurality of corresponding pairs comprise an image-to-image pair and a text-to-image pair. The method further includes predicting the output image rendition of the scene.

  • Patent number: 11045235
    Abstract: Embodiments relate to devices, systems, kits and methods for achieving maxillo-mandibular fixation (MMF). In an embodiment, a system comprises a plurality of dental occlusion ties and/or tension band ties (referred to herein as “DO ties” and “TB ties,” respectively). In another embodiment, a system or kit can comprise a plurality of one or both of DO ties and/or TB ties as well as a trimming tool, comfort caps or material, a lip/cheek retractor, and/or an instruction sheet. DO ties and TB ties can simplify the management of mandible fractures and maxilla fractures by helping re-establish precise dental occlusion for MMF.

  • Publication number: 20170281149
    Abstract: Disclosed is a self-retaining retractor configured for insertion into an orifice. The self-retaining retractor may include a flexible structure made of, for example, one or more of an elastic polymer sheet and an elastic polymer mesh. Further, the self-retaining retractor may include a flexible or shape memory material, such as, for example, nitinol, polymer or elastomer, incorporated in the flexible structure. Further, the shape memory material may be configured to change a state of the self-retaining retractor between a collapsed state and an expanded state. Accordingly, in the collapsed state, the self-retaining retractor may be conveniently inserted into the orifice. Subsequently, the self-retaining retractor may be changed to the expanded state in which the self-retaining retractor applies outwardly radial force causing the orifice to increase in size.

  • Publication number: 20150272698
    Abstract: A navigation system for an airway of a lung includes a wire configured to be inserted into the airway of a patient. The wire may include at least one fiber optic cable with a bragg grating. The system may also include a processing system configured to display a map of at least a portion of the airway. The processing system may be operably coupled to the wire and may be configured to identify a location of the wire on the map.
