Latest Patents

One of Robert W. Smith's latest patents is focused on in-situ process monitoring for powder bed fusion additive manufacturing (PBF AM) processes using multi-modal sensor fusion machine learning. This invention involves capturing computed tomography (CT) scans of a part being made via additive manufacturing. A neural network (NN) is utilized during the build of a new part to process multi-modal sensor data. The invention employs spatial and temporal registration techniques to align the data to x, y, z coordinates on the build plate. By superimposing the multi-modal sensor data on the build plate, the NN can predict where defects may occur during the actual build of a part.

Another significant patent by Smith is for a high-efficiency moving-magnet loudspeaker. This invention incorporates a thermoacoustic driver with a linear electrodynamic motor, a driver suspension housing, and a piston. The design includes a stiffness-enhancing device that raises the mechanical resonance frequency of the electrodynamic motor without reducing the piston stroke. The optimization of suspension spring structures and the use of starfish structures enhance the flexural or torsional stiffness of the device, contributing to its overall performance.
