A major barrier to the widespread adoption of wireless sensors for structural health monitoring is the requirement to power the network of wireless nodes. Batteries have a limited lifespan, adding significant size, weight, and costs to the wireless sensor network,and may represent a long term environmental problem. Battery maintenance can be eliminated by harvesting energy from the environment. Fo ...

Structural monitoring of Navy aircraft is of critical importance as the fleet ages. One critical area includes the control surfaces, which are subject to intense, dynamic buffet loading which can lead to structural cracking. The highly transient nature of buffet loading makes it difficult to measure using conventional sensors. We propose to solve this problem by combining a network of time-synchro ...

This Phase II proposal addresses the need for an innovative, affordable spray-on material system that mitigates low frequency acoustic radiation through a ship hull induced by airborne noise in shipboard compartments containing various electro-mechanical systems. The Phase I project objectives were fully achieved and the results exceeded the U.S. Navy project requirements. The acoustic mitigation ...

The objectives of the base project are three-fold: 1) An existing prototype hardware spectrum analyzer receiver system will be enhanced, tested in house, and ruggedized to enable it to be field tested at a federal test site (in the option). Work will focus on dynamic range improvements, continuous time coverage, and aims for innovation with multi-stage processing approaches to be analyzed and demo ...

Bridger Photonics proposes developing an optical metrology probe with a wavelength greater than 2 microns capable of transmitting through key infrared materials, achieving

Bridger Photonics proposes developing a disruptive metrology probe capable of achieving 1 kHz update rates and measurement ranges exceeding 10 cm. This probe will be coupled with OptiPro Systems' 5-axis air-bearing UltraSurf stage to provide optical figure and transmitted wavefront error of large aspheric optics including conformal windows, aerodynamic domes, and corrector optics.
