Abstract:
1. A micro-electromechanical systems (MEMS) driving arrangement for an electronic device, the micro-electromechanical systems (MEMS) driving arrangement comprising: a driven wheel having a diameter, comprising (n) teeth about an outer periphery thereof, wherein (n) is a positive integer; an actuator ring having an inner diameter that is greater than the diameter of the driven wheel, comprising (n)+(x) teeth about an inner periphery thereof and wherein (x) is an integer of at least 1; wherein subsets of the (n)+(x) teeth of the actuator ring progressively engage and disengage subsets of the (n) teeth of the driven wheel; a driving actuation assembly, coupled to the actuator ring, for driving the actuator ring in a hysteresis motion so as to cause rotation of the driven wheel, the driving actuation assembly comprising: wherein the driven wheel rotates in response to engagements and disengagements between selective subsets of the (n) teeth of the driven wheel with selective subsets of the (n)+(x) teeth of the actuator ring.
