RFID and Sensor Network Automation in the Food Industry by Selwyn Piramuthu,Weibiao Zhou Pdf

Radio Frequency Identification (RFID) is a key technology in the food industry that facilitates real-time visibility of items as they move through the supply chain and on to the end-consumer. Among all the currently available automatic identification technologies, RFID has clear dominance in terms of its ability to support real-time two-way communication, data storage and update, authentication, ambient condition sense and report, batch read without direct line-of-sight, operation in harsh environments and sensor-based applications. RFID and Sensor Network Automation in the Food Industry provides sufficient detail on the use of RFID and sensor networks from `farm to fork' (F2F) to allow the reader to appreciate the myriad possible applications of RFID and associated sensor network systems throughout the entire food supply chain. This includes precision agriculture, the provision of seamless visibility in track and trace applications, reduction of wastage, identification of counterfeits and contamination sources, remaining shelf-life applications for perishables, and quality and safety measures, among others. Providing state-of-the-art information from peer-reviewed research publications as well as general industry trends, this book will be of interest to all stakeholders in the agri-food supply chain, and academics and advanced students with an interest in these fields.

Methodology for the Digital Calibration of Analog Circuits and Systems by Marc Pastre,Maher Kayal Pdf

Methodology for the Digital Calibration of Analog Circuits and Systems shows how to relax the extreme design constraints in analog circuits, allowing the realization of high-precision systems even with low-performance components. A complete methodology is proposed, and three applications are detailed. To start with, an in-depth analysis of existing compensation techniques for analog circuit imperfections is carried out. The M/2+M sub-binary digital-to-analog converter is thoroughly studied, and the use of this very low-area circuit in conjunction with a successive approximations algorithm for digital compensation is described. A complete methodology based on this compensation circuit and algorithm is then proposed. The detection and correction of analog circuit imperfections is studied, and a simulation tool allowing the transparent simulation of analog circuits with automatic compensation blocks is introduced. The first application shows how the sub-binary M/2+M structure can be employed as a conventional digital-to-analog converter if two calibration and radix conversion algorithms are implemented. The second application, a SOI 1T DRAM, is then presented. A digital algorithm chooses a suitable reference value that compensates several circuit imperfections together, from the sense amplifier offset to the dispersion of the memory read currents. The third application is the calibration of the sensitivity of a current measurement microsystem based on a Hall magnetic field sensor. Using a variant of the chopper modulation, the spinning current technique, combined with a second modulation of a reference signal, the sensitivity of the complete system is continuously measured without interrupting normal operation. A thermal drift lower than 50 ppm/°C is achieved, which is 6 to 10 times less than in state-of-the-art implementations. Furthermore, the calibration technique also compensates drifts due to mechanical stresses and ageing.

Nanoscale Matter and Principles for Sensing and Labeling Applications by Dambarudhar Mohanta,Purushottam Chakraborty Pdf

Zusammenfassung: This book is a compilation of carefully chosen chapters that cover the subjects of nanoscale matter, sensing, and labelling applications. It is aimed primarily at scientists and researchers who are already involved in theme-based research or who are just starting their careers. Despite the diverse nature of the topics covered, which include a range of materials in various forms and uses, the emphasis is primarily on sensing and labelling phenomena. The book begins with materials quantification in nanoscale systems by using an innovative technique like "molecular secondary ion mass spectrometry without calibration standards". Subsequently, the book features an array of materials such as inorganic semiconductor nanoscale particles, carbon dots, rare-earth oxides, polymer nanocomposites, and a few biomaterials, all of which illustrate their functionality and potential for deployment in a wide variety of sensing applications. Although the book delves into the technical aspects of fabrication workouts to some extent, the focus is predominantly on the physical principles, mechanisms, and relevance involved in sensing and labelling applications. The book covers a wide range of topics that leverage the unique properties of nanoscale materials. By carefully selecting appropriate active materials, the authors explore the detection of LPG, hazardous and explosive gases, as well as humidity sensing and hydrogen evolution. It also delves into photo-sensing and persistent photoconductivity by using nanoscale semiconductors, which are used for heavy metal sensing and UV sensing, respectively. The use of metal nanoparticles in various forms is reviewed to address issues related to water contamination, biofilm protection, and food-borne pathogens. The book also discusses surface plasmon resonance, starting with its basic principles and expanding to its relevance in a broader perspective, with a greater focus on applied biosensing. Nanoscale ferrites and magnetic systems are explored with an emphasis on magnetic sensing and actuation. Lastly, the book explores the use of rare-earth-based nanosystems, highlighting persistent luminescence and up/down-converted transitions, which have unprecedented applications in bioimaging and biolabeling. Every effort has been made to strike a balance between the observed phenomena in the emerging areas of sensing applications and suitable theoretical treatments there in.
