    摘要: A method for communication in ultra-wide bandwidth RFID systems includes the steps of generating through a transceiver device an interrogation signal composed of at least a sequence of equally time spaced pulses within a period and transmitting the signal to at least one RFID identification device which generates a response signal and transmits it back to the transceiver device. The interrogation signal is coded according to a numerical coding sequence. The response signal is generated by varying, in each period of the pulse sequence of the interrogation signal, a polarity of pulses using the numerical coding sequence. An apparatus for communication in ultra-wide bandwidth RFID systems includes a transceiver device and a RFID identification device, suitable for communicating with each other. The RFID identification device includes a backscatter modulator suitable for modulating a signal reflected by an antenna of an identification device RFID.

    摘要: 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.

    摘要: A method for determining the depth from digital images (R, T) relating to scenes (I), comprising the following steps: A. acquiring at least one digital image (R, T) of a scene (I); B. acquiring sparse depth values (Sij) of said scene (I) relating to one or more of said pixels (pij) of said digital image (R, T); C. generating meta-data related to each pixel (pij) of said digital image (R, T) acquired in said step A correlated with the depth to be estimated of said image (I); D. modifying said meta-data generated in said step C, relating to each pixel (pij) of said digital image; and E. optimizing said meta-data modified in said step D, so as to obtain a map representative of the depth of said digital image (R, T) for determining the depth of said digital image (R, T) itself.
