Abstract: A method includes collecting, for a pitch, per pitch data that includes a plurality of first arm orientation data points and a plurality of second arm orientation data points. The method further includes analyzing the per pitch data to determine a release point arm orientation and an effort level. The method further includes calculating a per pitch stress level based on the release point arm orientation and the effort level. The method further includes calculating, for a set of pitches, a fatigue level based on the per pitch stress level of each pitch of the set of pitches.

Abstract: A system and method for using performance signatures can include generating a set of performance features during an activity of the first participant by collecting kinematic data from at least one inertial measurement unit and generating a set of biomechanical signals; combining the set of performance features into the performance signature; generating at least a second performance signature from a set of participants; comparing the performance signature of the first participant to at least the second performance signature; and applying a result of the comparison to an interaction with at least one participant.

Abstract: A system and apparatus for mounting an overhead display device to gaming machines. The system and apparatus featuring mounting elements securable to a display device at a selected distance and mounting hardpoints on one or a plurality of gaming machines. The hardpoints having a recess with a size and shape corresponding to that of the mounting elements. Wherein the display is securable to gaming machines in an overhead configuration when the mounting elements are secured to hardpoints and where the distance between the mounting elements corresponds to the distance between the hardpoints to which they are respectively secured.
