Patent ID: 7810372

Claim:
A system for measuring one or more of the following: payout, static friction and kinetic friction comprising: at least one substrate positioned on an XYZ translational substrate bed; a sample holder for supporting a sample, wherein the sample holder and the sample are positioned perpendicular to the XYZ translational substrate bed; a force device placing a predetermined weight onto the sample holder, the predetermined weight determining a contact force placed by the sample onto the substrate; a frictionless bearing table connected to the sample holder; a stationary frictionless bearing table positioned parallel to the XYZ translational substrate bed; a friction sensor connected to the sample holder and the stationary frictionless bearing table; a balance for obtaining a first substrate weight before movement of the XYZ translational substrate bed and a second substrate weight after movement of the XYZ translational substrate bed; and a controller operably coupled to the XYZ translational substrate bed, the balance, and the friction sensor, the controller configured to: configure the balance to obtain the first substrate weight and the second substrate weight; configure the XYZ translational substrate bed to move the XYZ translational substrate bed at a first sweep speed in a first direction and at a second sweep speed in a second direction relative to the sample; analyze one or more friction values, measured by the friction sensor, generated at a sample contact point located between the sample and the substrate during movement of the XYZ translational substrate bed; and determine one or more of a static friction value based on the one or more friction values, a kinetic friction value based on the one or more friction values, and a payout value based on the first substrate weight and the second substrate weight.
