A musical instrument stand has a joint, a leg support frame having a base bar and a first leg rod disposed on the base bar, the joint having a first tube connected to the first leg rod, a second tube connected to a second leg rod, and a third tube connected to a third leg rod, a main hollow rod disposed on the joint, and an upper rod. Standoffs and mechanical supports are then fabricated by etching to produce voids with the dielectric oxides on both sides of the device layer serving as suitable etch stops. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width. Each wafer tumbler includes a rider element selectively engaged with a base element in first and second engagement positions, wherein the first engagement position corresponds to a first key and the second engagement position corresponds to a second key. The predictor translates into a second set of one or more microinstructions to conditionally perform the operation when the prediction does not make a prediction.
