Abstract: Enhancing financial literacy using the metaverse. Visual, immersive financial content is provided via an augmented reality environment or a virtual reality environment. The content changes based on one or more financial factors, allowing users to visually and virtually experience and better understand how different prospective financial transactions are impacted by different financial factors of those transactions.

Abstract: Mobile painting systems are generally described. In some examples, a mobile painting system may include a vehicle with a wireless receiver, a first motor configured to drive at least one wheel of the vehicle, a first power supply configured to supply power to the first motor, and a recessed portion sized and shaped so as to receive a paint tray. The mobile painting system may include a painting device including a wireless transmitter, a first selectable control, and a second power supply. The first selectable control may transmit control signals effective to control operation of the first motor when received by the wireless receiver of the vehicle.

Abstract: Differentiation of access within the metaverse. According to one aspect, a metaverse visualization of an environment is modified as viewed by an avatar upon access of the environment by another avatar. According to another aspect, access of an avatar to a restricted access environment within the metaverse enables trusted avatars selective access to the restricted access environment together with the avatar.

Abstract: A tissue removal tool for use with an endoscope. The tool includes a loop formed by a piece of wire. The loop is movable between an open position and a closed position. The shape of the loop is defined in the open position by a proximal portion and a distal portion. The piece of wire may have a cross-sectional height in the proximal portion unequal to a cross-sectional height in the distal portion.

Abstract: A computer system for implementing a non-fungible token (NFT) as a payment object in a metaverse space. The system includes one or more processors and non-transitory computer-readable storage media encoding instructions which, when executed by the one or more processors, causes the computer system to create: a mint engine programmed to generate an NFT having a unique visual appearance, the NFT being associated with a currency account and including an authorization credential for the currency account; a ledger engine programmed to maintain the NFT on a ledger; a wallet engine programmed to generate a presentation of the NFT in response to a user request, wherein the presentation includes the visual appearance of the NFT to provide a visual representation of the authorization credential; and a transaction engine programmed to access the currency account, based on the authorization credential, in response to a payment request.

Abstract: The present subject matter discloses a tissue removal tool for use with an endoscope. The tool comprises a loop formed by a piece of wire and movable between an open position and a closed position, and a transmitting assembly comprising: a handle; and a link having a first end attached to the handle and a second end attached to the loop, the loop portion being movable between the open and closed position by action of the handle. The loop is defined in the open position by a proximal portion and a distal portion. The widest portion of the loop is more proximal to a proximal end of the loop than the mid-point of the length of the loop is.

Abstract: A tissue removal tool includes a body, a conduit, a loop, and a transmitting assembly. The conduit is attached to the body and defines an inner lumen, where the inner lumen has a proximal portion having a first width and a distal portion having a second width that is greater than the first width. The loop is movable between an open position in which the loop is at least partially disposed outside of the conduit and a closed position in which the loop is disposed within the conduit. The transmitting assembly includes a handle and a link. The handle is connected to the body, and the link has a first end attached to the handle and a second end attached to the loop such that movement of the handle causes the loop to move between the open and closed positions.

Abstract: A surgical instrument may have a handle, a support sleeve, and an inner sleeve. Illustratively, the support sleeve may be configured to actuate relative to the inner sleeve to protect the inner sleeve before and after a surgical procedure and to expose a portion of the inner sleeve during the surgical procedure. In one or more embodiments, an application of a force to a distal end of the support sleeve may be configured to retract the support sleeve relative to the inner sleeve. Illustratively, a reduction of a force applied to the distal end of the support sleeve may be configured to extend the support sleeve relative to the inner sleeve.

Abstract: A steerable laser probe may include a handle, an actuation lever, an optic fiber, and a housing tube. The housing tube may have a first housing tube portion having a first stiffness and a second housing tube portion having a second stiffness. The second stiffs ness may be greater than the first stiffness. The optic fiber may be disposed within the housing tube and within an inner bore of the handle. An actuation of the actuation lever about a pivot pin of the handle may gradually curve the optic fiber. An actuation of the actuation lever about the pivot pin of the handle may gradually straighten the optic fiber.

Abstract: A tip protector for attaching to a distal tip of an endoscope includes a cage and positional membrane. The cage has a proximal end, a distal end, and a plurality of holes disposed between the proximal end and distal end. The cage defines a channel that extends from the proximal end to the distal end. The positional membrane is attached to the cage, and the positional membrane includes a main opening and a plurality of air flow openings. The main opening is for receiving a distal tip of an endoscope, and the air flow openings are for allowing air flow through the positional membrane. The positional membrane is configured to attach the tip protector to the endoscope such that the endoscope is disposed within the channel between the proximal end and the distal end. When the tip protector is attached to the endoscope, the cage does not contact the endoscope.
