Abstract: A value is assigned to a rate threshold for adding child nodes to a distinct parent node in a tree data structure. A first datum comprising a first variable assigned a first value and a second variable assigned a first value is added to the tree at a first timestamp, by adding to the first level in the tree a first parent node representing the first variable assigned the first value and adding to the second level in the tree a first child node representing the second variable assigned the first value and connected by a first directed edge from the first parent node. A second datum comprising the first variable assigned the first value and the second variable assigned a second value is received at a second timestamp. The method blocks adding to the second level in the tree a second child node representing the second variable assigned the second value and connected by a second directed edge from the first parent node when a rate based on the first timestamp and the second timestamp exceeds the rate threshold.

Abstract: The present disclosure is directed to an article of footwear having an upper and a sole coupled to the upper. The sole includes an insole for receiving a foot of a wearer and a sole member disposed below the insole to support the foot of the wearer. The sole member includes a web extending along a length of the sole and a plurality of pillars projecting upwardly from the web toward the insole. The plurality of pillars each include a curved sidewall and a lid extending from an upper end of the curved sidewall. The curved sidewall and the lid define a cavity. The web and the plurality of pillars of the sole member are unitary and made of an elastomeric material that allows the pillars to flex or deform at a compressed state and return to an upright position at a relaxed state.

Abstract: An article of footwear includes an upper and a sole coupled to the upper, where the sole includes dispensed components having a non-hollow spiral geometry. The spiral dispensed components may be dispensed onto the upper and may extend vertically from the upper with layers of the spiral geometry stacked on top of each other. The spiral dispensed components are disposed adjacent to each other along lateral and longitudinal directions of the sole.
