The mono-wiper is fundamentally constructed from 3 4-bar mechanisms linked in series. Our kinematic analysis consisted of vector loops for each 4 bar.
Calculations:
Mobility:
1 half joint (gear), all others full
DoF = 3*9 - 3 - 2*11 - 1 = 1

We found that the wiper arm base rocker has a range of motion of 2.16 radians (124 degrees) for a full rotation of the input crank.
Simulation:
θ2 is the input crank angle.
