1. An apparatus (10′), comprising:
a uniformity device (10u) that determines uniformity of a workpiece (TW), wherein the uniformity device (10u) includes: a lower workpiece-engaging portion (18) that interfaces with an upper workpiece-engaging portion (20u); and a computing resource (75) communicatively-coupled to one or more components of one or both of the lower workpiece-engaging portion (18) and the upper workpiece-engaging portion (20u) by one or more communication conduits (77), wherein the lower workpiece-engaging portion (18) includes a central shaft (36) having a proximal end (36P) and a distal end (36D) and an elongated body (38) that extends between the proximal end (36P) and the distal end (36D), wherein the lower workpiece-engaging portion (18) includes a motor (40), wherein the proximal end (36P) of the central shaft (36) is connected to the motor (40), wherein the lower workpiece-engaging portion (18) includes a radially manipulatable workpiece-engaging chuck (44) that is connected to the distal end (36D) of the central shaft (36), wherein the upper workpiece-engaging portion (20u) includes an axially-movable cylinder (58) having a proximal end (58P) and a distal end (58D) forming a recess (60) that is sized for receiving the radially inwardly/outwardly manipulatable workpiece-engaging chuck (44); and a first tire tread-engaging portion (100u) opposingly-arranged with respect to a second tire tread-engaging portion (101u), wherein each of the first tire tread-engaging portion (100u) and the second tire tread-engaging portion (101u) includes a tire tread-engaging member (112u), wherein the first tire tread-engaging portion (100u) includes a uniformity-detecting portion (110u) connected to the tire tread-engaging member (112u), wherein the first tire tread-engaging portion (100u) includes a tire tread-engaging member (112u1) including a plurality of roller members (118u) rotatably connected to an upper bracket (120u) and a lower bracket (122u), wherein the plurality of roller members (118u) consists of: only two roller members (118u1, 118u2).
