Abstract:
Ultra-wideband (UWB) sensors are a radio frequency technology that use wireless communication between devices to precisely determine the position. The most recent applications focus on locating and sensor data collecting on mobile phones, car keys and other similar devices. However, this technology is still not being utilized in the mining sector. To overcome this gap, this perspective offers implementation options and solutions. Additionally, it evaluated the benefits and drawbacks of using ultra-wideband for mining. The measurements provided were made using QORVO two-way ranging sensors, and these were compared to theoretical and existing technological solutions. To ensure the optimal use of UWB sensors, a special emphasis was placed on certain influencing factors, such as ways of locating via UWB and factors affecting measurement accuracies, such as the line of sight, multipath propagation, the effect of shielding and the ideal measurement setup. A conducted experiment showed that the most accurate results are obtained when there is no multipath propagation and the arriving signal travels directly from the transmitter to the receiver.

Abstract:
This study is the part of our ongoing research on using ultra-wide band (UWB) technology for navigation at the Ohio State University. Our tests have indicated that the UWB two-way time-of-flight ranges under indoor circumstances follow a Gaussian mixture distribution that may be caused by the incompleteness of the functional model. In this case, to adjust the UWB network from the observed ranges, the maximum likelihood estimation (MLE) may provide a better solution for the node coordinates than the widely-used least squares approach. The prerequisite of the maximum likelihood method is to know the probability density functions. The 30 Hz sampling rate of the UWB sensors enables to estimate these functions between each node from the samples in static positioning mode. In order to prove the MLE hypothesis, an UWB network has been established in a multi-path density environment for test data acquisition. The least squares and maximum likelihood coordinate solutions are determined and compared, and the results indicate that better accuracy can be achieved with maximum likelihood estimation.

Abstract:
Indoor positioning systems have been widely studied in the last decade due to the need of humans for them especially in the large building such as malls, airports, hospitals...etc. Still, there is no suitable precise indoor positioning system which can be implemented for different indoor environments and situations. We should mention military urban and emergency situations. In military urban and emergency response operations, the time is a crucial issue, and a precise positioning system with a clear indoor covering is a highly prerequisite tool to enhance safety. It should be seamless, low, frugal, power efficacious, low cost and supply less meter-level accuracy. In emergency scenarios, we don't have enough flexibility and time to install all anchor nodes in a proper situation that may help to obtain an appropriate accuracy for locating a mobile station, but command centers require observing their operational forces, and rescuers demand to detect potential victims to perform proper care. The most common users for these situations are the firefighters, police, military, and civilians. The main goal of this Ph.D. dissertation is to create an accurate indoor positioning (IP) system that could be used in different indoor environments and situation, especially for the emergency situation. So, we create this system through different steps as explained below. First, we have considered the study of different radio technologies to choose the suitable radio technology called Ultra wide band (UWB) radio technology. The reasons of selection the UWB and the commercial device that implements such technology are explained in details in chapters 3 and 4. Afterward, due to some impacts of the UWB in indoor environments (see chapters 4 and 5), we continue the study of NLOS identification and mitigation methods. In these chapters, we create two different NLOS identification and mitigation methods using a commercial UWB device experimentally. The first method used two parameters extracted from the UWB device to identify the propagation channel and map information of the building that the method is experimentally done in it to mitigate the NLOS channel. The second method of NLOS identification and mitigation used three parameters extracting from the UWB device to be an input set of the Fuzzy logic technique used to identify the propagation channels. In this identification method, it is not only to identify the prorogation channel to NLOS and LOS but also to divide the NLOS channel into hard and soft channels. Then, we created a database that includes the three parameters and the distance Bias to mitigate the NLOS channel for obtaining an accurately estimated distance to be used for creating an accurate IP system. Finally, with the aim of applying our designs to mass market applications, we move to create a novel IP system using the UWB technology called anchor selection (AS). In this technique, we focus on using fewer sensors (anchor nodes) to locate a mobile station under harsh circumstances such as scenarios where the installation area of the anchor nodes is narrow and/or the installation time should be very short. The proposed approach is based on grouping anchor nodes in different sets and evaluating the positioning error of each of these groups by means of a novel mean squared error (MSE)-based methodology. A virtual node approach is also proposed to consider the case where position must be computed with only two anchor nodes.

Abstract:
In biomedical applications realistic phantoms are becoming more useful for validation and testing of precursor systems. These artificial phantoms require stable and flexible tissue-mimicking materials with realistic dielectric properties in order to properly model human tissues. We have fabricated a low-water-content, low cost, mechanically and electrically stable, good shelf life and multi-layered heterogeneous phantom consisting of skin, fat and muscle tissues. We have chosen semi-solid type phantom for each tissue layer. The size and thickness of the each layer is chosen based on the average thickness of human tissue. Altering the ingredient composition wisely we can alter its dielectric properties also. By reason of no osmosis occurrence, the tissues can be employed to construct heterogeneous phantoms or even anthropomorphic phantoms without causing any changes in geometry or electrical properties. The performance of the fabricated phantom is carried out using an open-ended coaxial slim probe system by Agilent Technologies. Nearly all previous studies were based on very high frequency( VHF), so we present ultra-wide band (UWB), 500MHz-20GHz multilayered phantoms. We have measured our phantom after 2 month time period and we got quite good results for the dielectric properties without having significant variations. Thus, our fabricated sets of ATE phantom have good long lasting properties with good physical and dielectric stability.

Abstract:
Dans cette thèse nous nous sommes principalement concentrés sur les transmissions impulsion radio Ultra Large Bande (UWB-IR) qui a plusieurs avantages grâce à la nature de sa bande très large (entre 3.1GHZ et 10.6GHz) qui permet un débit élevé et une très bonne résolution temporelle. Ainsi, la très courte durée des impulsions émises assure une transmission robuste dans un canal multi-trajets dense. Enfin la faible densité spectrale de puissance du signal permet au système UWB de coexister avec les applications existantes. En raison de toutes ces caractéristiques, la technologie UWB a été considérée comme une technologie prometteuse pour les applications WSN. Cependant, il existe plusieurs défis technologiques pour l'implémentation des systèmes UWB. A savoir, une distorsion différente de la forme d'onde du signal reçu pour chaque trajet, la conception d'antennes très larges bandes de petites dimensions et non coûteuses, la synchronisation d'un signal impulsionnel, l'utilisation de modulation d'onde d'ordre élevé pour améliorer le débit etc. Dans ce travail, Nous allons nous intéresser à l'étude et l'amélioration de la synchronisation temporelle dans les systèmes ULB
The basic concept of Impulse-Radio UWB (IR-UWB) technology is to transmit and receive baseband impulse waveform streams of very low power density and ultra-short duration pulses (typically at nanosecond scale). These properties of UWB give rise to fine time-domain resolution, rich multipath diversity, low power and low cost on-chip implementation facility, high secure and safety, enhanced penetration capability, high user capacity, and potential spectrum compatibility with existing narrowband systems. Due to all these features, UWB technology has been considered as a feasible technology for WSN applications. While UWB has many reasons to make it a useful and exciting technology for wireless sensor networks and many other applications, it also has some challenges which must be overcome for it to become a popular approach, such as interference from other UWB users, accurate modelling of the UWB channel in various environments, wideband RF component (antennas, low noise amplifiers) designs, accurate synchronization, high sampling rate for digital implementations, and so on. In this thesis, we will focus only on one of the most critical issues in ultra wideband systems: Timing Synchronization

Abstract:
Wearable technologies need a smooth and unobtrusive integration of electronics and smart materials into textiles. The integration of sensors, actuators and computing technologies able to sense, react and adapt to external stimuli, is the expression of a new generation of wearable devices. The vision of wearable computing describes a system made by embedded, low power and wireless electronics coupled with smart and reliable sensors - as an integrated part of textile structure or directly in contact with the human body. Therefore, such system must maintain its sensing capabilities under the demand of normal clothing or textile substrate, which can impose severe mechanical deformation to the underlying garment/substrate. The objective of this thesis is to introduce a novel technological contribution for the next generation of wearable devices adopting a multidisciplinary approach in which knowledge of circuit design with Ultra-Wide Band and Bluetooth Low Energy technology, realization of smart piezoresistive / piezocapacitive and electro-active material, electro-mechanical characterization, design of read-out circuits and system integration find a fundamental and necessary synergy. The context and the results presented in this thesis follow an “applications driven” method in terms of wearable technology. A proof of concept has been designed and developed for each addressed issue. The solutions proposed are aimed to demonstrate the integration of a touch/pressure sensor into a fabric for space debris detection (CApture DEorbiting Target project), the effectiveness of the Ultra-Wide Band technology as an ultra-low power data transmission option compared with well known Bluetooth (IR-UWB data transmission project) and to solve issues concerning human proximity estimation (IR-UWB Face-to-Face Interaction and Proximity Sensor), wearable actuator for medical applications (EAPtics project) and aerospace physiology countermeasure (Gravity Loading Countermeasure Skinsuit project).

Having a device with the capability of measure motions from gait produced by a human being, could be of most importance in medicine and sports. Physicians or researchers could measure and analyse key features of a person's gait for the purpose of rehabilitation or science, regarding neurological disabilities. Also in sports, professionals and hobbyists could use such a device for improving their technique or prevent injuries when performing. In this master thesis, I present the research of what technology is capable of today, regarding gait analysis devices. The research that was done has then help the development of a suggested standalone hardware sensor node for a Body Area Network, that can support research in gait analysis. Furthermore, several algorithms like for instance UWB Real-Time Location and Dead Reckoning IMU/AHRS algorithms, have been implemented and tested for the purpose of measuring motions and be able to run on the sensor node device. The work in this thesis shows that a IMU sensor have great potentials for generating high rate motion data while performing on a small mobile device. The UWB technology on the other hand, indicates a disappointment in performance regarding the intended application but can still be useful for wireless communication between sensor nodes. The report also points out the importance of using a high performance micro controller for achieving high accuracy in measurements.

Abstract:
Ce travail de thèse s’articule autour de la problématique du respect des gabarits spectraux d’émission imposés par les règlementations et les normes dans le domaine des émetteurs radio impulsionnels ultra-large bande. Le choix a été fait de réaliser un capteur in-situ venant extraire les informations nécessaires à une estimation sur puce de la densité spectrale de puissance. Un algorithme d’estimation embarqué peut alors permettre de détecter les gabarits violés et pouvoir rétroagir sur le dispositif. La grande diversité constatée parmi les règlementations et les normes en vigueur ainsi que dans les différentes architectures de générateurs d'impulsions a alors motivé la réalisation d'un système de calibration universel à tous les émetteurs par prise d'informations en sortie. Le manuscrit s'est alors employé à représenter une impulsion à partir de son enveloppe instantanée et de sa fréquence instantanée, ces deux grandeurs temporelles pouvant être extraites pour tout type d'impulsions. Il a été également proposé dans le chapitre une première technique de calibration basée sur la modification de l'enveloppe à des instants précis qui permet de faire rentrer le spectre dans le gabarit tout en maximisant l'occupation de celui-ci. Enfin, l'extraction de l'enveloppe instantanée et de la fréquence instantanée a été abordée en proposant une technique d'extraction par transposition de l'information en bande de base. La conception des dispositifs électroniques nécessaires a été présentée et ceux-ci ont été implémentés sur la même puce qu'un générateur d'impulsions dans le but de réaliser un démonstrateur qui a validé l'utilisation du système étudié
This thesis focusses on the power emission constraints defined by regulations and standards for every kinds of ultra-wide band impulse radio transmitters. In fact, these power emission constraints have to be respected all along the device life. Also, an integrated sensor able to extract the essential information for an on-chip estimation of the power spectral density has been realized. Then, an embedded algorithm is added to the system and detects if a power limit is broken. If necessary, it acts on the transmitter to solve the problem. In the first chapter, a large variety of power constraints shapes and several architectures of impulse generators have been observed and studied. Therefore, the aim of this thesis is to realise a calibration system which would be universal to all impulse radio transmitters. After its extraction at the output of the transmitter, information have to be downconverted in order to reduce the constraints on conversion stage but without using a local oscillator and a mixer. A model for the impulse signal based on the instantaneous envelop and on the instantaneous frequency has been proposed in the second chapter. A new calibration method based on these two signals is also presented. The last chapter concentrates on detailing the extraction of the instantaneous envelop and the instantaneous frequency. The design of the electronic devices essential to this extraction is presented and a chip has been realised and the viability of the solution shown

Abstract:
Les systèmes radio impulsionnelle Ultra large bande (IR-ULB), de part la nature de leurs signaux et de leurs architectures, montrent des caractéristiques intéressantes pour concurrencer les technologies existantes (Zigbee, Bluetooth et RFID) pour certaines applications nécessitant un faible coût et une faible consommation de puissance. Dans ce contexte cette thèse évalue les potentialités des systèmes IR-ULB pour la réalisation d’objets communicants miniatures.En utilisant une technologie "System In Package" (SiP), des objets communicants ULB prototype intégrant une ou plusieurs puces CMOS et une antenne ULB directement réalisée sur le boîtier sont présentés dans la thèse. Les transitions entre le circuit imprimé et les puces sont réalisées avec des fils d'interconnexion ("wirebonding"). Les points d'étude de la thèse se focalisent particulièrement sur la mise en boîtier d'une puce ULB et sur la conception sur silicium de la tête radio fréquence d'un système ULB. La réalisation d'une interconnexion faible cout par "wirebonding" entre un circuit intégré ULB et son support est problématique aux fréquences utilisées en ULB (3-10 GHz) en raison des éléments parasites importants limitant sa bande passante. Pour obtenir une transition ne dégradant pas les signaux ULB, plusieurs méthodologies d’interfaçage sont proposées permettant de réaliser sans augmentation notable de cout une transition large bande entre le circuit intégré et le circuit imprimé du boîtier. L'intégration en technologie CMOS standard des éléments principaux constituant la tête radio fréquence d'un système ULB impulsionnel (LNA, détecteur d'impulsions et générateurs d'impulsions) est étudiée. L'intérêt d'un co-design entre le silicium et le circuit imprimé lors de la conception de ces éléments est mis en avant. L'intégration ainsi que la miniaturisation du système final dans une technologie SIP sont également présentées
Due to the nature of their signals and their architectures, Impulse Radio Ultra Wide Band (IR-UWB) systems show interesting features to compete with existing technologies (Zigbee, Bluetooth and RFID UHF) for low cost and low power applications. In this context, this thesis evaluates the potential of UWB systems for the realization of miniature communication devices.The thesis presents UWB communicating devices realized with a System in Package (SiP) technology. Devices incorporate one or several CMOS chips and an antenna directly printed on the board (PCB). Transitions between the PCB and the chips are made with standard wire bonds. The thesis especially focuses on packaging of UWB dice and on the design of UWB front end radio frequency.Due to important parasitic elements limiting its bandwidth, wire bonds transition is problematic for UWB applications (3-10 GHz). This thesis proposes several methodologies to interface integrated circuit and PCB to obtain a broadband transition without increasing cost production. The integration in standard CMOS technology of main components comprising the UWB radio frequency front end (LNA, pulse detector and pulse generator) is studied. The interest of a co-design between silicon and PCB to design these elements is pointed up. Integration and miniaturization of the final system in a SIP technology are also presented

Abstract:
The use of valid, accurate and reliable systems is fundamental to warrant a high-quality data collection and interpretation. In 2015, FIFA created a department of Electronic Performance and Tracking systems, collecting under this name the more used tracking systems in team sport setting: high-definition cameras, Global Positioning Systems, and Local Positioning Systems. To date, LPS systems proved to be valid and accurate in determining the position and estimating distances and speeds. However, it is hypothesized that between LPS, ultra-wide band (UWB) is the most promising technology for the future. Thus, this chapter was aimed to make an update about UWB technology in sport: the FIFA’s regulation, manufacturer that provide this technology, the research articles that assessed validity and reliability of UWB technology, and the criteria standard for the use of this technology.

Abstract:
The performance of printed wideband antennas has to be optimized both in frequency and time domains, to qualify for UWB applications. This is especially true in multi-resonant antenna topologies where the excitation of different modes can change phase centers and radiation patterns with frequency. The study presented in this chapter intends to demonstrate the simulation and experimental design for the time domain characterization of UWB antennas. Modeling the antenna as a linear time-invariant system with transfer function and impulse response, distortion caused to a nanosecond pulse is analyzed. Two planar monopole antenna designs are considered for the comparative study: the SQMA and RMA. SQMA is a traditional CPW-fed monopole design with ground modifications for ultra wide-bandwidth. RMA is a rectangular CPW-fed monopole with an impedance transformer arrangement at the antenna feed. RMA maintains constant impedance over the entire UWB and contributes towards maintaining uniformity in the radiation patterns over the entire frequency band by its design. Transfer function measurements are performed for both the azimuthal and elevation planes and the impulse responses are deduced by performing IFFT. Parameters such as FWHM and ringing are computed from the impulse response for the performance comparison. To evaluate the influence of the antenna geometry on a transmitted/received pulse, the impulse responses are convoluted with a standard UWB pulse. The time-domain distortion for the designs is then compared by computing the Fidelity parameter.

Abstract:
Original proposal objectives: Our main original goal was to develop ultra-fast methods and instrumentation for the analysis of hazardous chemicals in the food supply. We proposed to extend the QuEChERS approach to veterinary drugs and other contaminants, and conduct fast and ultra-fast analyses using novel 5MB-MS instrumentation, ideally with real samples. Background to the topic: The international trade of agricultural food products is a $1.2 trill ion annual market and growing. Food safety is essential to human health, and chemical residue limits are legislated nationally and internationally. Analytical testing for residues is needed to conduct risk assessments and regulatory enforcement actions to ensure food safety and environmental health, among other important needs. Current monitoring methods are better than ever, but they are still too time-consuming, laborious, and expensive to meet the broad food testing needs of consumers, government, and industry. As a result, costs are high and only a tiny fraction of the food is tested for a limited number of contaminants. We need affordable, ultra-fast methods that attain high quality results for a wide range of chemicals. Major conclusions, solutions and achievements: This is the third BARD grant shared between Prof. Amirav and Dr. Lehotay since 2000, and continual analytical improvements have been made in terms of speed, sample throughput, chemical scope, ease-of-use, and quality of results with respect to qualitative (screening and identification) and quantitative factors. The QuEChERS sample preparation approach, which was developed in conjunction with the BARD grant in 2002, has grown to currently become the most common pesticide residue method in the world. BARD funding has been instrumental to help Dr. Lehotay make refinements and expand QuEChERS concepts to additional applications, which has led to the commercialization of QuEChERS products by more than 20 companies worldwide. During the past 3 years, QuEChERS has been applied to multiclass, multiresidue analysis of veterinary drug residues in food animals, and it has been validated and implemented by USDA-FSIS. QuEChERS was also modified and validated for faster, easier, and better analysis of traditional and emerging environmental contaminants in food. Meanwhile, Prof. Amirav has commercialized the GC-MS with 5MB technology and other independent inventions, including the ChromatoProbe with Agilent, Bruker, and FUR Systems. A new method was developed for obtaining truly universal pesticide analysis, based on the use of GC-MS with 5MB. This method and instrument enables faster analysis with lower LaDs for extended range of pesticides and hazardous compounds. A new approach and device of Open Probe Fast GC-MS with 5MB was also developed that enable real time screening of limited number of target pesticides. Implications, both scientific and agricultural: We succeeded in achieving significant improvements in the analysis of hazardous chemicals in the food supply, from easy sample preparation approaches, through sample analysis by advanced new types of GC-MS and LCMS techniques, all the way to improved data analysis by lowering LaD and providing greater confidence in chemical identification. As a result, the combination of the QuEChERS approach, new and superior instrumentation, and the novel monitoring methods that were developed will enable vastly reduced time and cost of analysis, increased analytical scope. and a higher monitoring rate. This provides better enforcement, an added impetus for farmers to use good agricultural practices, improved food safety and security, increased trade. and greater consumer confidence in the food supply.
