A method and apparatus of generating haptic cues for pacing and monitoring are disclosed. A metal mounting plate is fixedly attached to an outer surface of the belt receiving member and an L-shaped metal sleever bar receiving member with a substantially vertically oriented arm and a substantially horizontally oriented arm is pivotally attached parallel with an outer surface of the mounting plate for limited rotary movements of the vertical arm relative to the mounting plate. Some embodiments include constructions having micro-structures therein which correspond to voids, conduits, insulative structures, semiconductor structures or conductive structures. After the silicon deposition, the wafer is oxidized which completely closes the otherwise reduced micropipes.
