A printed circuit board for deployment of a sensor chip of an optical head of an endoscope is described. The modulating unit includes a matrix of pixels, and a light-shielding portion between each of the pixels. Iterative steps and complimentary extraction techniques are employed by one or more processors to create an importable design model of the parameterized feature, which is imported into a target CAD system. The rules look at probabilistic information and also look at patterns within the data, attempting to find where intrusions may exist prior to their actual occurance. The duty-cycle signal is input to the coil, controlling the coil on and off and, thereby rotating the motor.
