The Physics of Fluids, 2023
Axial flow circulating pumps (AFCP) are one of large marine steam turbine unit for large-sized ships. One peculiar operation condition for AFCP is when a ship cruises beyond a certain speed, the energy of pump inflow is able to completely overcome the ...

Unpowered Knee Exoskeleton during Stair Descent
2021 7th International Conference on Mechatronics and Robotics Engineering (ICMRE), 2021This study developed an unpowered knee exoskeleton which used the custom-built spiral spring to convert negative work to assist knee extension during stair descent. The optimization of the function angle and the stiffness of spiral spring were conducted to get the optimal parameters.

Prediction and Application of Unpowered Descent & Ascent of Deep-sea HOV
International Conference on Computer Science and Network Technology, 2023Unpowered descent/ascent is the preferred way for deep-sea Human Occupied Vehicle (HOV) to descend and ascend. Unpowered descent/ascent can greatly save the energy of the HOV to improve the underwater operation time, which is one of the important ...

Unpowered Wireless Ultrasound Sensor
ASME 2010 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, Volume 2, 2010This paper presents a wireless ultrasound sensor that uses frequency conversion to convert the ultrasound signal to a microwave signal and transmit it directly without digitization. Constructed from a few passive microwave components, the sensor is able to sense, modulate, and transmit the full waveform of ultrasound signals wirelessly without ...
