Abstract: Embodiments disclosed herein include systems and methods for regulating pneumatic gas propulsion. More specifically, some embodiments include a first spring that exerts a spring force, where the spring set point increases as the first spring is compressed. Similarly, some embodiments include a piston that is in physical communication with the first spring and a valve. The valve mechanism may receive the gas, where upon the gas being received by the valve mechanism at a pressure that meets the spring set point, the gas causes the piston to move in the longitudinal direction. Further, movement of the piston creates a cylinder space between the piston and the valve mechanism, where a volume of the cylinder space is defined by a position of the piston. The pressure causes the piston to compress the first spring until an equilibrium exists between the gas force and the spring force.

Abstract: A method for processing ultrasonic response signals collected from a plurality of measurement locations along a weld to determine the presence of a defect in the weld may include filtering an ultrasonic response signal from each of the measurement locations to produce a filtered response signal for each of the measurement locations. Thereafter, an ultrasonic energy for each of the measurement locations is calculated with the corresponding filtered response signal. The ultrasonic energy for each measurement location is then compared to the ultrasonic energy of adjacent measurement locations to identify potential defect locations. When the ultrasonic energy of a measurement location is less than the ultrasonic energy of the adjacent measurement locations, the measurement location is a potential defect location. The presence of a defect in the weld is then determined by analyzing fluctuations in the ultrasonic energy at measurement locations neighboring the potential defect locations.
