Abstract: An article of footwear can include an upper and a sole member coupled to the upper, where the sole member comprises a plurality of spaced apart apertures extending through the sole member. The article of footwear can further include a plurality of individual sensory nodes, where each sensory node has a first end coupled directly to the upper and an opposite, second end configured to engage with a ground surface. Each sensory node is configured to translate freely within a respective aperture of the sole member.

Abstract: States are identified in a time ordered sequence of data that have a temporal component. Data that includes a plurality of snapshots is received. Each snapshot of the plurality of snapshots includes a plurality of sensor measurements captured from distinct sensors at a common time point. The plurality of snapshots are time ordered. Root mean square error (RMSE) values are computed between successive pairs of the plurality of snapshots in time order. A peak is identified in the computed RMSE values. A valley is identified in the computed RMSE values. A stable state is determined as occurring from the identified peak to the identified valley. The determined stable state is output.
