With parametric resonance, the mirror is driven by a square waveform (50% duty cycle) with drive frequency fdrive = 2 × fres/N (N = 1,2,3,…, in ambient air, we use N = 1).
The mirrors are driven by the electrostatic force, and have two states, i.e., '1' state (or 'static/off' state) corresponding to motionless mirrors or mirrors that are released to their zero-bias voltage position and '-1' state (or 'on' state) in accordance to the fully deflected mirrors.
For a raster scan, the x and y scanner mirrors were driven by two sawtooth signals at different frequencies.
For raster-scanned images, the x- and y-scan mirrors were driven by a three-axis card (ISS) and synchronized with the data acquisition card.
For scanning in a circular orbit, the x and y scan mirrors are driven by two identical sine waves with a 90° phase shift.
The mirrors are driven in a preset scanning path using the ISS 3-axis card (ISS, Champaign, IL) and synchronized with data acquisition using the ISS-FCS dual channel card (ISS).
In many accounts of the MNS, it is assumed that mirror neurons are driven by the sensory data and that when the mirror neurons discharge, the action is 'understood'understood
Consistent with the PC account, the empirical evidence does not support the view that mirror neurons are driven solely by sensory data from focal action stimuli.
You need to make sure that the screws or nails you hang your mirror from are driven directly into the studs.
The fact that mirror neurons can be driven by backward connections is consistent with recent predictive coding models of mirror neuron function [42 44].
