The present invention relates to high quality composite materials from fibrous materials, in which the composite incorporates a polymer matrix embedding individual fibers. The system includes a correction scheme including temporarily replacing a defective pixel with a linear interpolation of the defective pixel’s surrounding neighboring pixel values, determining a local gradient based in part on the acquired image and a gradient kernel, and providing a correction value based on the local gradient to correct the defective pixel. The negative voltage generator is configured to provide a negative voltage with respect to the second voltage to an input of the first inverter in response to a control signal for performing at least one of a read or a write operation of a memory bit cell coupled to the word line. The exhaust orifices are configured to effectively cool the leading edge portion of the blade and to reduce the likelihood of cracking of the outer wall forming the leading edge. The return member may be a spring or an elastomeric O-ring that also seals the thermal actuator against intrusion of contaminants from the use environment.
