Methods and apparatus for quantifying pneumatic volume usage via valve controllers are disclosed. An example apparatus includes a valve controller operatively couplable to a pneumatic actuator, the pneumatic actuator being operatively coupled to a control valve. In response to an input signal indicating that a flow control member of the control valve is to be moved in a specified direction, the valve controller commands a current-to-pressure (I/P) converter of the valve controller to pulse a relay valve of the valve controller between a closed position and an open position. The pulsing of the relay valve causes the pneumatic actuator to move the flow control member in the specified direction. The valve controller calculates a pneumatic volume usage associated with the moving of the flow control member in the specified direction. The pneumatic volume usage is based on the pulsing of the relay valve.

METHODS AND APPARATUS TO MONITOR A CONDITION OF A STRUCTURE
Methods, apparatus, and articles of manufacture to monitor a condition of a structure are disclosed. An example apparatus includes an operational collection engine to measure first operational acceleration information from a first sensor installed at a first location and second operational acceleration information from a second sensor installed at a second location on a structure, a first vibration model response calculator to calculate a first vibration model response by entering the measured first and second operational acceleration information into a first vibration model, a second vibration model response calculator to calculate a second vibration model response by entering a calculated number of operational cycles into a second vibration model, a deviation threshold analyzer to determine a difference between the first vibration model response and the second vibration model response and an alert generator to generate an alert to identify a condition of the structure based on the difference between the first vibration model response and the second vibration model response.
A method of fabricating a finished part includes generating or creating a master pattern using an additive manufacturing process, and the master pattern corresponds in shape to the finished part. A shell is created by applying one or more layers of one or more coating materials to the master pattern. The master pattern is then dissolved while the master pattern is in the shell to create a cavity in the shell that corresponds in shape to the finished part. A molten material is then poured into the cavity of the shell. The molten metal is allowed to cool and to harden and/or to reach a determined temperature such that the molten metal becomes the finished part. The shell is then removed from around the finished part.
