Abstract: A dynamic imaging system for use with endoscope, or as an element of a video endoscope, utilizes path length differences and/or a variable aperture size to expand a usable depth of field and/or improve image resolution in an area of interest in the image field. In some implementations, the imaging system utilizes a variable aperture in conjunction with unequally spaced image sensors placed downstream from a beam splitter. An imaging system captures multiple focal planes of an image scene on separate sensors. A variable aperture permits the capture of enhanced resolution images or images with longer depths of field. These differently focused images and/or images with different resolutions and depths of field are then combined using image fusion techniques.

Abstract: Systems and methods are provided that enable contextual correction functions based on a current step in a surgery or surgical procedure and based on what is displayed on a display. By using information about what is depicted on the display and the current step of the surgery or surgical procedure, a controller can implement data models that automatically perform correction functions without the need for physician input.

The processing unit is further configured to associate each of the plurality of discrete patterns with a desired command of the plurality of commands and store each of the plurality of discrete patterns with the desired command of the plurality of commands in the memory unit so as to customize a control of the medical imaging scope.

Abstract: A system and method for providing an exercise bar for a user to use for rowing or other exercises in the water of the spa or adjacent to the spa. The exercise bar may comprise a central hub, and two sides, each with a first inner tube attached to opposing side of the central hub and a an outer tube in telescoping connection with the inner tube, and a handgrip in connection with the first outer tube. A connector may be mounted to the central hub, the connector to enable the exercise bar to be connected to one or more resistance cables. The exercise bar may be adjustable from a first, shorter length for use with exercises in which a user's hands are positioned closer together and a second, longer length for use with exercises in which a user's hands are positioned father apart.

Abstract: This disclosure relates generally to systems, devices, and methods of use thereof regarding headrests for selectively removable spa seatbacks. In some embodiments, headrests of the present disclosure include a pillow and a manifold to (a) receive the pillow and (b) selectively engage the selectively removable spa seatback. In some embodiments, headrests of the present disclosure include a pillow and a manifold, where the manifold includes a platform to receive the pillow, a body for engaging with the selectively removable spa seatback, and a constraining plate to restrict a movement of a portion of the body.
