A near-field/far-field transformation for circular aperture antennas, formulated as a linear inverse problem, is here proposed. The approach takes into account for the a-priori information about the radiating and geometrical characteristics of the antennas under test, by representing the aperture field with Circular Prolate Spheroidal Wave functions.

This paper proposes the realization and preliminary characterization of a smart sensor platform for the online monitoring of the residual life of activated carbon air based filters. The platform performs the measurement to give reliable information about the filter maintenance or early warning for the presence of dangerous gases both in industrial and military scenarios. A preliminary feasibility study has been carried out to evaluate the activated carbon filter electrical impedance sensitivity to chemicals adsorption. After a detailed presentation of the employed hardware and software solutions, a description of the experimental setup is given and a preliminary proof of the assumed relationship is provided.

In this paper, we discuss the upcoming network stack LoRaWAN and its underlying modulation technology LoRa, which is an implementation of a LPWAN (Low Power Wide Area Network) and consider practical limitations that can occur when restricted Machine-to-Machine (M2M) data agreements for the connection of LoRa gateways to a cellular network are involved. We provide a theoretical estimate of the maximum possible communication range of a LoRa link depending on output power and spreading factor and illustrate a LoRa-transceiver's contrary behaviour of energy consumption and range versus the achievable data rate by means of current consumption and RF output power measurement results for different combinations of modulation parameters. Our analysis of the data overhead introduced by LoRa gateways identifies that the amount of generated backhaul network traffic can cause substantial costs for IoT service providers in case of cellular-connected gateways or limit the number of supported sensor nodes.

In this paper, a detailed study on the applicability of various current sensor technologies and the corresponding measurement accuracy for power consumption characterization of Wireless Sensor Networks (WSN) nodes is presented and discussed. This study is useful to plan strategies to increase the life of the network and to plan the replacement of the sensor node before a failure occurs. Power consumption management of WSN is aimed to maximize the lifetime of the network within given power constraint. In this context, each node should operate in order to ensure the highest energy efficiency without energy waste. In particular, transmission and reception often are the most consuming tasks in a wireless sensor node and must be properly characterized to maximize the WSN performance.

A novel technique based on the Field Mapping Algorithm (FMA) is proposed to gauge reflector surface smoothness from near-field reflector measurements. The proposed method provides exact information of the antenna surface with much less computation time compared with other available techniques. A few examples are given to illustrate the advantages of the new surface-analysis technique.

In this paper preliminary results from investigations of the proof of concept of a nonlinear (vibrational) bistable inductive energy harvester are presented. The main idea proposed through this paper is to exploits the benefits of the snap-through buckling configuration in terms of capability to scavenge energy from wide band vibrations and the possibility to use the beam switching between its stable states to move (contactless) a magnet inside a coil, thus producing a voltage. The simplicity of the harvester and the wide operating range of frequencies, are the two main claims of the proposed setup. The main novelty of the proposed approach arises from the coupling of the nonlinear bistable architecture with the inductive transducer and the possibility to convert the mechanical energy gained by the switching beam into an electrical signal without mechanical links. The system, in its infancy, has been observed to produce powers in the order of microwatts.

Monitoring system designed for biological and marine environment observation are equipped with different types of sensors related to different disciplines. For each sensor integrated in the system it is necessary to develop a driver (software/firmware) specific to its operation. This kind of approach limits the system flexibility because the addition of a new sensor involves the update of the entire software control. For this reason it is important to reduce the time and simplify the work required to integrate new sensors. This paper present GAMbUSIA (GenerAl purpose Metalanguage for instruments with Serial InterfAce) wich aim to improve code reuse and system flexibility. GAMbUSIA is a metalanguage, based on eXtensible Markup Language (XML), with which it is possible to describe the communication protocol at a high level and use (and reuse) this description instead to develop an ad-hoc driver. In order to evaluate the proposed solution, Gambusia is used to create an oceanographic sensor description in a data acquisition system.

Brain-Computer Interface (BCI) is an innovative communication technique mainly used in biomedical applications for assisting devices. In this context, main aim is help people with severe disabilities restore the movement ability, or replace lost motor function controlling external devices, or communicate with other people leading them to become more self-sufficient. The connection between BCI and wireless communication standards brings BCI into the Internet of Things (IoT), giving the opportunity to better interconnect the brain of both able and disable people with the surrounding physical and cyber worlds: it is called the human in the loop paradigm. The combination of BCI and IoT falls within the wider topic of Cognitive IoT technology, an enriched solution for Industry 4.0 and IoT in industry. The integration of the human role in the IoT can lead to several advantages both in human life and in technological progress. As a novel measurement device, BCI has to be widely characterized in order to improve the reliability of the obtained result. In this work, the authors review the scientific challenges of electroencephalography data acquisition for BCI, the parameters influencing its variability, and the processing techniques for a correct feature extraction and data classification. In particular, first the influence factors and the issues of EEG acquisition are reviewed. Then, the most popular devices used for BCI sensing unit are described. Finally, the authors describe the post processing techniques, the feature extraction algorithms, and the the classifier to properly choose the right signal feature.

In this paper a Fault Tolerant system for the attitude estimation of an Unmanned Aerial Vehicle (UAV) using low cost magnetometers, accelerometers, and gyroscopes, implemented in an Inertial Measurement Unit (IMU) is proposed. An approach based on the Unscented Kalman Filter (UKF) for Detection, Isolation and Reconfiguration is investigated in the presence of a Hardware Duplex IMU mounted on board for flight control purposes. A state automaton, with comparative logics, detects if anomalies occurr on one of the two IMUs; then based on a comparison between the measured variables and their UKF estimations, the fault is isolated and identified. The proposed approach is an alternative to standard Hardware Triplex IMU architectures based on triple physical redundancy. At the expense of a higher computational cost and a small delay in isolating faults, the UKF based approach allows to limit the number of IMUs to two, or to guarantee a fail safe behavior in the presence of a double fault, even if contemporary, with Triplex IMUs. Experimental results on the implementation of a multiple IMU platform on a quadrotor flight control board are finally presented.
