SKI WAX SELECTION DEVICE Russian patent published in 2015 - IPC A63C11/04 

FIELD: instrumentation.

SUBSTANCE: proposed device comprises base, power supply, control unit, measuring unit including n simulation discs and assemblies of couplers and locks of simulation discs. Measuring unit comprises extra n angular acceleration transducers, step motor to drive n torque transmission assemblies. The latter are coupled by vertical displacement assemblies with n simulation discs and assemblies of couplers and locks of simulation discs. To ensure uniform pressure of simulation disc on snow and required moment of inertia, said coupling and locking assemblies are provided with weights.

EFFECT: higher accuracy, accelerated determination of wax sliding properties.
