Abstract:
A sinking rope structure (100) that comprises an outer layer (1) and a core (10) consisting of a tubular sheath (2) closed transversally by a plurality of welded portions (3) in order to form filled chambers (4) arranged in series and separated by the welded portions (3). More in detail, the filled chambers (4) are filled with a filling material, generically a granular material or a liquid with specific weight higher than one to obtain a sinking rope. In particular, the method for making the core (10) is based on a vertical form-fill-seal process to obtain filled pouches in series.
Abstract:
A low- cost and non- invasive method for remote monitoring deformations of a structure (2), which method envisages to couple at least two RFID tags (3) to the structure (2) in its respective points (10a, 10b, 10a-10c), to interrogate at radio frequency the RFID tags (3) so that a resultant electromagnetic field is produced at a certain distance (DINF) from the structure (2), the resultant electromagnetic field ensuing from a combination of the electromagnetic fields produced individually by each RFID tags (3) in response to the interrogation, to measure the resultant electromagnetic field at such a distance (DINF) from the structure (2) for obtaining measurements of the resultant electromagnetic field, and to determine the deformations of the structure (2) as a function of the measurements of the resultant electromagnetic field.
