This Project will provide technical and scientific support for the design and development of a distance measurement industrial system and for its integration in the SAYME wireless sensor networks system. Several sensor technologies will be considered and their compliance with the low cost, low power and small form factor specifications of the SAYME system will be evaluated. Moreover, signal processing algorithms will be developed to process sensor signals in order to provide reliable and accurate measurements.

The goal of this project is to develop a wireless distributed system for monitoring and predictive maintenance of tower cranes. The system will increase the security at work in this field since it is able to predict potential failures and to assess the risk of fall of the crane. The system consists on a set of wireless sensors (to measure load, wind speed, etc ) transmitting data to an acquisition and signal processing unit located close to the crane. The sensors and the unit communicate to each other using the ZigBee standard.
SETEL S.A., Gobierno de Cantabria (INVESNOVA 2004)
In this project the GTAS group developed a wireless system for information delivery among the different coachs of a train. Basically, the system is composed of an industrial PC, working as a video server, and several devices equipped with wireless 802.11 cards. The system permits the transmission of video, images or other information to passengers, as well as the transmission of other information among coachs useful, for instance, for synchronization between carriages. The system was successfully installed in several trains of the spanish FEVE railroad company.
This is one of a set of collaboration projects with Nuclenor to improve and update the integrated intrumentation system of the nuclear power plant of Santa María de Garoña (Spain). This project includes hardware and software developments.
In this project we developed a digital modem for communications through low power electric lines, specifically in the CENELEC A band (9-95kHz), with application to remote control and billing. During the project the particular characteristics of this transmission channel were studied (low SNR, impulsive noise, impedance variations, ...). Also the influence of these impairments in the parameters of the designed modem (shaping filter, oversampling ratio, synchronism, ...).
SETEL, S. A., as a part of the european project PROMOSHYGES (BRITE-EURAM 789)
This was a european project within the BRITE-EURAM framework with the final goal of monitoring large turbo-generator sets in hydroelectric plants. The project leader was Iberdrola (SP) and, besides the GTAS group, the rest of partners were ANSALDO (IT), IRCOM (FR), LETI (FR) and the groups of mechanical engineering and photonics of the University of Cantabria. The work of our group was focused on the development of a flexible and powerful acquisition and signal processing unit that we called DASPU (Digital Acquisition Signal Processing Unit).
In this project the GTAS group developed a unit called DAT (Digital to Analog Transmodulator), which receives the satellite digital TV signal (QPSK modulated) and transforms this signal into a conventional analog PAL channel. The DAT carries out the following tasks: QPSK demodulation, FEC channel decoding (Reed-Solomon and Viterbi), demultiplexing of the MPEG-2 stream and audio /video decoding en enconding form MPEG to PAL. We used chips from LSI LOGIC and made the design, implementation and evaluation of the overall system.
In this project we developed a TDT to operate in Satellite Master Antenna TV (SMATV) systems. The goal of the TDT is to transmodulate the digital TV signal from the satellite link modulation (QPSK) to the cable modulation format (64-QAM). The main tasks of the TDT are: QPSK demodulation, forward error correcting code (Reed-Solomon y Viterbi) and QAM modulation. A new Reed-Solomon encoder is introduced as a channel encoder for the cable link. For the design of the TDT we used chips from LSI LOGIC. More than 50000 units of the final product were sold by IKUSI in several countries.
