An imbalance in the transport current among the strands of a Cable-in-Conduit conductors (CICC) can be associated with the change of their performance. In order to understand and improve the performance of CICC’s, it is essential to study the current imbalance. This paper focuses on the study of the current imbalance in two short samples of the SeCRETS (Segregated Copper Ratio Experiment on Tra...

− For monitoring the shape of fast rotating objects such as turbo machine rotors, contactless and compact sensors with a high measurement rate as well as high precision are required. We present a novel laser Doppler distance sensor for shape measurements of rough technical surfaces. This novel sensor offers concurrently high distance resolution in the micron range and high temporal resolution i...

Inertial instruments used to measure horizontal motion are sensitive to tilt. Tilt coupling induced by gravity exerting a force along the sensing axis of the instrument as a function of its inclination must be accounted for in numerous seismological studies and seismic isolation applications. There are, in theory, many ways to separate tilt and horizontal motion components by combining the meas...

Sensor fusion is commonly used to reduce uncertainty in localization, obstacle detection, and world modeling. However, sensor fusion can also be used to improve teleoperation. In particular, we can use sensor fusion to create user interfaces which efficiently convey information, facilitate understanding of remote environments and improve situational awareness. We do this by selecting complement...

Horizontal strain at the bottom of asphalt concrete due to repeated traffic loads is the most critical parameter in characterizing fatigue performance of flexible pavement. The study of horizontal strain is thus very important to understand the strain behavior, predict the fatigue life and implement in design and analysis. A total of twelve Horizontal Asphalt Strain Gages (HASGs), six gages ori...

Bend sensors have been developed based on conductive ink, optical fiber, and electronic textiles. Each type has advantages and disadvantages in terms of performance, ease of use, and cost. This study proposes a new and low-cost bend sensor that can measure a wide range of accumulated bend angles with large curvatures. This bend sensor utilizes a Bowden-cable, which consists of a coil sheath and...
