Design and testing of an improved animatronic toy actuator
… a single unit, eliminating the need for external gearing. Currently, such motion is actuated by direct current motors equipped with gear boxes that are both noisy and bulky. This new type of actuator will function more quietly, using a frequency lower than humans' sensory threshold for sound while …

The exploration of quieter actuation in animatronic toys
… were an effective way to reduce the sound from gear-boxes and actuators that currently actuate the line of animatronic toys made by the client. Several actuation methods and enclosure materials were considered and evaluated based upon their performance, relative quietness, and their viability in …

Design and testing of a concentrator wind turbine
… of the rotor is increased. This means expensive gear boxes are unavoidable. The rotor also becomes considerably more complicated in design and heavier as the size increases, to mitigate working stresses.<br></br><br></br>Flow concentrators have been investigated in an attempt to alleviate wind …

Methodologies for remaining useful life estimation with multiple sensors in rotating machinery
… in literature concerning prognostics in meshing gearboxes. Moreover, there are several but inconclusive works regarding bearing prognosis. Few research groups have studied multi-hour fatigue gear experiments and this was one of the contributions of this thesis. Moreover, the study expanded beyond …
