Groundwater Flux Measurement System
An eighteen-sensor VTP has been developed to measure groundwater fluxes across the ground surface. The thermistor technology employed in this new instrument eliminates the need for copper wires connecting the sensors to the data logger, optimizing ease of fabrication and allowing for very small sensor spacing near the ground surface to enhance the resolution...

Dynamic Electric Motor
A novel Brushless DC (BLDC) motor system. The design is intended to decouple the torque from the voltage in BLDC motors, allowing torque and speed to be independent. The outcome is consistently applying torque to the shaft while reducing parts and friction and providing greater system control.
Oceanographic exploration relies heavily on large dynamic-range...

Improved Marine Profiler
The Improved Marine Profiler enables longer deployment times and significantly improved data. This low-drag, flow-aligning profiler pivots both horizontally and vertically to orient with the incident current flow to minimize drag. By naturally orienting into the surrounding current flow, the new design also improves the data quality from sensors mounted...
