Recent advances on intelligent packaging as tools to reduce food waste

2018

[EN] Food waste is one of the main issues for international organisms. It is not only an ethical and economic issue but it also depletes the environment of limited natural resources. Among strategies suitable for fighting such challenge, intelligent packaging is an interesting tool to reduce waste derived from households and retailers. A revision of 45 recent advances in the area of optical systems for freshness monitoring is reported herein. The study covers fruits, vegetables, fish products and meat since they are the most representative fields of application. Furthermore, a discussion about the main research challenges and opportunities that will be faced by intelligent packaging in the …

Upgrading cultural infrastructures: Notes on the strategy concerning variable message signs on the European scene

2011

This paper presents the general strategy concerning Variable Message Sign harmonization in Europe represented by the work of the Expert and Study Group 4-Mare Nostrum (ESG4) within the EasyWay program. Co-funded by the European Commission and participated by 22 European Member States, EasyWay focuses on ITS implementation integrating stakeholders from the public and private sector. The paper shows some empirical data to illustrate the slow but careful, integral approach followed by ESG4 in order to issue specific recommendations concerning Variable Message Signs design and use in Europe.

Consensus-based Distributed Intrusion Detection for Multi-Robot Systems

2008

This paper addresses a security problem in robotic multi-agent systems, where agents are supposed to cooperate according to a shared protocol. A distributed Intrusion Detection System (IDS) is proposed here, that detects possible non-cooperative agents. Previous work by the authors showed how single monitors embedded on-board the agents can detect non- cooperative behavior, using only locally available information. In this paper, we allow such monitors to share the collected information in order to overcome their sensing limitation. In this perspective, we show how an agreement on the type of behavior of a target-robot may be reached by the monitors, through execution of a suitable consensu…

Synergic algorithms for the planning and the intelligent following of a trajectory for non-holonomic vehicles

2008

Although there are many studies about two wheels non-holonomic vehicles, in order to simplify the problem the planning and the following of trajectories or paths are generally considered two different phases. In this paper, two algorithms for the synergic working of trajectory planning with intelligent trajectory following are presented. The "trajectory shape" characteristics obtained in the planning phase are used for the efficient trajectory following. From the shape, in order to follow the trajectory, an intelligent controller calculates, without further elaboration, the reference wheels velocity of the vehicle. The knowledge of trajectory shape characteristics and curvature constraints …

Implementation of the ERI standard and Evaluation of Applications with several low-cost technologies

2008

The electronic registration and identification (ERI) systems allow carrying out a remote, secure and univocal identification of a vehicle through electronic devices. This paper presents the implementation of the ERI standard (ISO 24534 & 24535) in an API to develop applications. The implementation took into account the different components of the system to build the architecture of the identification system. Several applications have been developed in order to test this API with several low-cost technologies (Wifi, Bluetooth and RFID).

Implementation of a Drosophila-inspired orientation model on the Eye-Ris platform

2010

A behavioral model, recently derived from experiments on fruit-flies, was implemented, with successful comparative experiments on orientation control in real robots. This model has been firstly implemented in a standard CNN structure, using an algorithm based on classical, space-invariant templates. Subsequently, the Eye-Ris platform was utilised for the implementation of the whole strategy, at the aim to constitute a stand alone smart sensor for orientation control in bio-inspired robotic platforms. The Eye-Ris vl.2 is a visual system, made by Anafocus, that employs a fully-parallel mixed-signal array sensor-processor chip. Some experiments are reported using a commercial roving platform, …

Industrial applications of wireless networks: a bridge crane distributed control system based on bluetooth

2005

This paper shows the possibility to use Bluetooth for wireless short range communication in an industrial environment. In this line a distributed control system based on Bluetooth has been proposed for a bridge crane system. Its configuration is mainly based on the use of distributed nodes connected by means of Bluetooth. Traditionally many types of devices have been delivered as mechanical devices and more or less all or the intelligence and control has been added. Nowadays there is a growing trend towards a higher level of built-in intelligence in the devices, constituting the intelligent nodes. This type of systems allows the implementation of highly flexible control systems capable of a…

Towards roll-to-roll fabrication of electronics, optics and optoelectronics for smart and intelligent packaging

2004

Embedding of optoelectrical, optical, and electrical functionalities into low-cost products like packages and printed matter can be used to increase their information content. These functionalities make also possible the realization of new type of entertaining, impressive or guiding effects on the product packages and printed matter. For these purposes, components like displays, photodetectors, light sources, solar cells, battery elements, diffractive optical elements, lightguides, electrical conductors, resistors, transistors, switching elements etc. and their integration to functional modules are required. Additionally, the price of the components for low-end products has to be in cent sc…

ROAD project: Robotics for assisted diving

2014

The activities associated to underwater diving are of great importance in many areas. In the second half of the last century, diving technologies have greatly progressed, but diving is still characterized by significant risks, especially for professional divers who works at high depth, and limited practicability. The use of robotic systems and automatic procedures would allow, as in other situations where safety is of concern (for example, in case of hazardous works or in relation to hostile environments), a reliable monitoring and assessment of the physiological conditions of human operators during their activities. Moving from currently available technologies in underwater robotics, the R…
