Abstract: Systems, methods, and devices include a reconfigurable multi-purpose surgical tool with a housing having a plurality of portions for a plurality of surgical tools, such as a cautery tool, a scalpel tool, and/or a forceps tool. A first portion of the housing can house a first surgical tool. The first surgical tool is converted between an in-use configuration and a stored configuration. The stored configuration includes a first surgical tool portion of the first surgical tool being at least partially contained by the housing. The in-use configuration being when the first surgical tool portion is at least partially exposed from the housing. A second portion of the housing partially houses a second surgical tool. The second surgical tool includes another in-use configuration with the second surgical tool at least partially exposed from the housing. A third portion of the housing at least partially houses a third surgical tool.

Abstract: A system, methods, and techniques are provided for performing automated operations to track one or more physiological indicators of a user via hardware capabilities of a computing device associated with the user, and/or of external monitoring devices communicatively coupled to such a user computing device. Feedback regarding such tracked activities may be provided to the user via one or more guided physiological and/or exercises. The system may enable the user to interactively create and/or experience audiovisual artworks that may include still images, music, dynamic sound effects, and animations, such as animations depicting the creation of one or more related artworks.
