Vestibular prosthesis overview. The signal processor converts analog voltage outputs from inertial sensors (G1x3 and A1x3) into frequencies that match firing rates of vestibular neurons. Specifically the signal processor: (1) performs coordinate system transformation to align implanted and natural inertial sensors and optimize stimulation efficacy, (2) implements semicircular canal and otolith neural dynamics, and (3) generates clocks that can drive H-Bridge neural stimulation circuitry.
