    Abstract: Embodiments may include an expandable access system having contracted and expanded configurations. The system and methods may include an expandable access device having a helix or wrapped shape. Embodiments may include a cannula, stent, needle, trocar, introducer, fastener, and/or any other devices disclosed herein. Embodiments may also include an expandable trocar positionable in at least a portion of the access device. A sleeve or band may be disposed over at least a portion of the access device and configured to resist radial expansion of the access device. Expansion of the trocar and/or receipt of an object may radially expand the access device between a contracted configuration and an expanded configuration.

    Abstract: Data encryption and Human Pose Estimation based on imaging a body segment. A key for encrypting a data file is generated based on image data that represent a unique biometric feature of a body segment of a user or motion of the user. An image engine executes artificial intelligence to identify matching image data for decrypting the data file. The image engine is further trained to predict changes in image data due to aging, stress, and the like. An avatar associated with the user, which is generated based on a movement pattern of the user, is configurable for generating an encryption key and for use in an avatar-based language.
