Universitat Politècnica de Catalunya - UPC posted this:Novel acoustic wave device and filter for its use in high frequency applicationsAn acoustic wave device with one or more dielectric compensating layers that compensates the spurious signals by substantially temperature-independent nonlinearities occurring within the device has been developed. A direct application of this device has been the development of a novel acoustic filter. Partners to further develop the system and/or to establish commercial agreements with technical cooperation are sought.

Universidad de Alcalá-OTRI posted this:Vibroacoustic spectrometry system for the non-destructive analysis of materialsThe research group "Radiation and Sensing Group" of the University of Alcalá presents a system of non-destructive analysis of materials and structures, by spectral study of the indirect vibroacoustic excitations of the materials analyzed. By means of this system it is possible to perform in situ the analysis of materials and structures without previous treatments, solving with that the need to use coupling liquids that the current ultrasonic based systems currently use. The group seeks to reach licensing agreements, collaboration agreements or commercial agreements with technical assistance, with companies from the agrofood, pharmacy, construction, ceramics, wood, cork and other materials sectors.

This model is useful for communications and positioning systems. The proposed model provides the channel response for the usual environmental phenomena. The model simulate how these phenomena affect a particular acoustic signal, and therefore, the performance of an underwater system based on acoustic signals can be evaluated previously to its deployment. The model has been tested for the case of underwater localization systems. GEINTRA is looking for companies working in telecommunications and IT sectors or performing works related to exact science and physics to achieve technical cooperation agreements.

The serration and porous material work constructively with each other to significantly improve the aero-acoustic performance. An optimal choice of the porous materials has been identified, where it can achieve broadband noise reduction whilst completely suppressing the vortex shedding tone. This new device is more industrially-ready than the conventional “add-on” type serration due to its superior structural integrity. In addition it produces an aerodynamic performance similar to that of the baseline aerofoil. Applicable to a wide range from applications from drones, UAVs, aircraft engines, wind turbines and fan blades.
