Abstract: The invention discloses an integrated broadband energy collecting and sensing device for a rod-cable structure, belonging to a piezoelectric vibration energy collecting and sensing field, which solves a problem that an existing piezoelectric energy harvester does not fully collect environmental multi-directional vibration energy. The device comprises an inner layer sleeve, an outer layer sleeve, a first piezoelectric thin film sensor, a self-powered module and a control communication module. The self-powered module comprises one or more vibrator groups. Each vibrator group comprises a plurality of piezoelectric vibrators arranged in sequence along a circumferential direction of the inner layer sleeve. The vibrator group collects vibration energy in any direction in a cross section of the sleeve. An inner surface of the outer layer sleeve is provided with a plurality of amplitude limiting blocks for protecting the piezoelectric vibrator during a severe vibration.

Abstract: Non-destructive testing apparatuses, systems, and methods for assessing strain in structural components are disclosed. Structural components include induced predetermined regions having materials of varying density, including induced geometric patterns of differing densities within the structural component that can be a composite material structural component. The method includes projecting waves of energy, that can be beams of electromagnetic (EM) energy and/or waves of ultrasonic (UT) energy, into or through the structural component to evaluate the predetermined induced pattern region of varying density and determining existing strain within a structural component based on the detected energy response.

Abstract: An apparatus includes: a deflection acquiring unit that acquires a deflection amount caused in a measurement target region on a structure by a vehicle traveling on the structure; a vehicle position acquiring unit that acquires a position of the vehicle on the structure at time when the deflection amount is acquired; and a rigidity coefficient calculating unit that calculates a rigidity coefficient specifying a relation between a magnitude of a force applied to the structure due to a weight of the vehicle and flexural rigidity of the structure, from a relation equation, the acquired deflection amount, and the detected position of the vehicle. The relation equation is established among a position of the vehicle on the structure, the magnitude of the force, a position of the measurement target region on the structure, a length of the structure, the flexural rigidity, and a deflection amount caused in the measurement target region.

Abstract: In a device for evaluating torsional structural performance of girder according to an embodiment of the present disclosure, a guide unit of a support member formed in a shape of an arc having its center that matches a shear center of the girder rotatably supports a rotating member, so that the shear center of the girder matches a center of torsion during clockwise or counterclockwise rotation of the rotating member, thereby measuring an accurate angle of twist and preventing an incident in which the rotating member escapes due to separation of a component by a rotational force.

Abstract: A roadway segment includes a body having a length along a direction of travel, a width along a width axis, and top and bottom halves along a depth axis. The segment also includes a strain sensor array with one or more optical fiber cables embedded in the bottom half of the body. The strain sensor array includes vehicle-strain sensors configured to detect strain on the body resulting from vehicles traveling across the top surface. The segment also includes a processor that operates the plurality of vehicle-strain sensors at a resolution of not greater than one picometer (1 pm). Any segments of the optical fiber cable(s) that intersect are separated from one another depth wise by at least two-tenths of an inch (0.2 in.). Each of the sensors is separated from each other along the width axis by at least two inches (2 in.).

Abstract: A system network and methods supported by a constellation of GNSS satellites orbiting around the Earth, and deployed for precise remote monitoring of the spatial displacement, distortion and/or deformation of stationary and/or mobile systems, including buildings, bridges, and roadways. The methods involve (i) embodying multiple GNSS rovers within the boundary of the stationary and/or mobile system being monitored by the GNSS system network, (ii) receiving GNSS signals transmitted from GNSS satellites orbiting the Earth, and (iii) determining the geo-location and time-stamp of each GNSS rover while the stationary and/or mobile system is being monitored for spatial displacement, distortion and/or deformation, using GNSS-based rover data processing methods practiced aboard the system, or remotely within the application and database servers of the data center of the GNSS system network. The GNSS rovers also include on-board instrumentation for sensing and measuring the depth of water ponding about the GNSS rovers.
