Abstract: Various systems and methods that enhance an exercise or other physical activity performed by a user are described. In some embodiments, a classification system communicates with a media hub to receive images and perform various methods for classifying or detecting poses, exercises, and/or movements performed by a user during an activity. In some embodiments, the systems and methods include a movements database (dB) that stores information as entries relating individual movements to data associated with the individual movements. Various systems, including class generation systems and body focus/activity systems, can utilize the movements database when presenting class content to users and/or presenting exercise information (e.g., muscle groups worked or targeted) to the users.

Abstract: The present invention provides a vessel shuttle which can be used, for example, for moving reaction vessels to or from an assay resource station in an automated chemical analyzer. The vessel shuttle has a plurality of movable plates including first and second vessel carrying plates adapted to move cooperatively with respect to one another to advance a vessel stepwise along a linear path without net motion of the first and second vessel carrying plates as the vessel is advanced one step. In a preferred embodiment, the first and second vessel carrying plates each comprise a plurality of fingers defining recesses for receiving vessels and the first vessel carrying plate is adapted to move in a direction substantially perpendicular to the vessels' linear path and the second vessel carrying plate is adapted to move rectilinearly both generally parallel to and generally perpendicular to that linear path.
