Rob, actually its a neat idea. The key to low power operation is allowing the mirrors in the MEMS (or any system) to operate at their torsional resonance. This patent claims a means for adjusting the balance weights by means of laser etching. There have been recent developments whereby, the light sources are being placed on the oscillating surface. This means that for a given system the moment of inertia needs to be adjusted to keep the oscillating parts operating at their torsional resonance. So no matter what configuration is used this idea can allow the system to remain in tune. The other Patent talks about a piezo-electric device. (accelerometer) that are mounted on both sides of the mirror or oscillating plate. Basically these devices sense acceleration and at one point, specifically the zero crossing or Null point, the mirror or oscillating plate actually stops. By adding the two outputs together they cancel out each other when they pass this point. The heart of the VRD's systems timing is based on synching the rest of the drive and modulation electronics to this signal. This is just another way to do it.
