▼ Pulmonary functional testing is very common and widely used in today's clinical environment for testing lung function. The contact based nature of a Spirometer can cause breathing awareness that alters the breathing pattern, affects the amount of air inhaled and exhaled and has hygiene implications. Spirometry also requires a high degree of compliance from the patient, as they have to breathe through a hand held mouth piece. To solve these issues a non-contact computer vision based system was developed for Pulmonary Functional Testing. This employs an improved photometric stereo method that was developed to recover local 3D surface orientation to enable calculation of breathing volumes. Although Photometric Stereo offers an attractive technique for acquiring 3D data using low-cost equipment, inherent limitations in the methodology have served to limit its practical application, particularly in measurement or metrology tasks. Traditional Photometric Stereo assumes that lighting directions at every pixel are the same, which is not usually the case in real applications and especially where the size of object being observed is comparable to the working distance. Such imperfections of the illumination may make the subsequent reconstruction procedures used to obtain the 3D shape of the scene, prone to low frequency geometric distortion and systematic error (bias). Also, the 3D reconstruction of the object results in a geometric shape with an unknown scale. To overcome these problems a novel method of estimating the distance of the object from the camera was developed, which employs Photometric Stereo images without using other additional imaging modality. The method firstly identifies the Lambertian Diffused Maxima regions to calculate the object's distance from the camera, from which the corrected per-pixel light vector is derived and the absolute dimensions of the object can be subsequently estimated. We also propose a new calibration process to allow a dynamic (as an object moves in the field of view) calculation of light vectors for each pixel with little additional computational cost. Experiments performed on synthetic as well as real data demonstrate that the proposed approach offers improved performance, achieving a reduction in the estimated surface normal error by up to 45% as well as the mean height error of reconstructed surface of up to 6 mm. In addition, compared with traditional photometric stereo, the proposed method reduces the mean angular and height error so that it is low, constant and independent of the position of the object placement within a normal working range. A high (0.98) correlation between breathing volume calculated from Photometric Stereo and Spirometer data was observed. This breathing volume is then converted to absolute amount of air by using distance information obtained by Lambertian Diffused Maxima Region. The unique and novel feature of this system is that it views the patients from both front and back and creates a 3D structure of the whole torso. By observing the 3D structure of the…

▼ Energy transport analysis of micro/nano optics as well as their optimization to achieve high-throughput deep nanoscale patterning and microscopy is the goal of this study. To understand the energy transport in nano-optical devices, the transient heating behavior of a commercial available nano-optical probe, NSOM, under pulsed laser operation is examined first. Based on the thermal analysis, it is observed that the major limitation of the NSOM probe under higher energy operation arises from the joule heating of its thin metal coating and the resulting thermal/mechanical damage during operation. Based on the understanding, a diffraction-based micro-zone plate (MZP) optical probe suffers less from joule heating and with advantages of higher optical throughput as well as longer working distance is designed and constructed. The MZP is fabricated at the end face of an optical fiber with a micro-fabrication technique based on e-beam negative tone lift-off lithography on non-planar substrates. The fabricated MZP can achieve spot sizes ~ 0.7λ at a focus distance of ~ 6λ with an optical transport efficiency of 20 %, which is more than 3 orders higher than that of NSOM. To further reduce the size of the focus spot to deep sub-wavelength scales and to eliminate metallic structures which can cause joule heating during high energy operation, two all-dielectric optical probes are then designed/constructed, namely, (a) solid immersion probe, and (b) scattering dielectric probe. Both dielectric probes focus light by combining more than one of the diffraction mechanisms associated with dielectric material (e.g., refraction, solid immersion, Mie and near-field Rayleigh scattering) to achieve deep nanoscale light focusing with minimum energy loss. The solid immersion optical probe is constructed with a ball lens and microsphere for macro to micro scale focusing with far field refraction and micro to mesocale focusing with solid immersion. The ball lens and the microsphere are stacked on an optical fiber for achieving the cascade focusing configuration. The solid immersion probe can achieve a focus spot size of ~ 0.45λ/n (~ 0.3λ when n = 1.5) on a target in the near field of the surface of the microsphere when the light is radially polarized. To achieve an even smaller focal spot in the near field, the scattering dielectric optical probe combines the verified solid immersion probe with a nano-scatterer at its focal spot. Due to the near-field Rayleigh scattering, the nano scatterer can induce a deep nanoscale spot with a diameter comparable to the forward radius of curvature of the scatterer under radially polarized light. It is verified with full wave electrodynamics simulations that the resulting scattering optical probe can achieve a ~10 nm spot with an intensity enhancement of ~ 10⁵, which can be valuable in all kinds of bio-detection as well as nano fabrications. At the end of the Ph.D study, mechanisms for deep sub-wavelength imaging resolutions with microspheres, which is recently demonstrated in different groups, are… Advisors/Committee Members: Wen, Sy-Bor (advisor), Suh, Steve (committee member), Yu, Choongho (committee member), Su, Chin B (committee member).

ENGLISH ABSTRACT: The measurement and analysis of whole-body vibration was done in accordance with ISO 2631-1 at a South African opencast mine to identify potentially unhealthy levels of vibration present in vehicles. Impulsive whole-body vibration was found on all measured vehicles and 90.6% of test cases showed possibly unhealthy levels of vibration exposure. The impulsiveness of the vibration led to the underestimation of the exposure by the RMS method. Bulldozer operators were exposed to the highest average levels of whole-body vibration. It is strongly advised that the use of high exposure vehicles are limited and that job rotation is implemented to limit the vibration exposure of these individuals. The vehicle tasks are used for as well as operating conditions were found to have a significant impact on whole-body vibration. A suitable measurement duration for different types of vehicles were statistically identified and it was found that measurement durations greater than 30 min and 60 min are sufficient to measure whole-body vibration with measurement errors of less than 25% (sufficient accuracy) and 12.5% (preferable accuracy) respectively.

AFRIKAANSE OPSOMMING: Die meet en analise van heel-liggaam vibrasie is in ooreenstemming met ISO 2631-1 by ’n Suid-Afrikaanse oopgroefmyn gedoen om moontlike ongesonde vlakke van vibrasie teenwoordig in voertuie te identifiseer. Impulsiewe heel-liggaam vibrasie was in alle voertuie teenwoordig en 90.6% van toetsgevalle het gedui op moontlike ongesonde vlakke van vibrasie blootstelling. Die impulsiwiteit van die vibrasie het gelei tot die onderskatting van die blootstelling vlakke deur die RMS-metode. Stootskraperoperateurs was aan die hoogste gemiddelde vlakke van heel-liggaam vibrasie blootgestel. Dit word sterk aanbeveel dat die gebruik van hoë blootstelling voertuie beperk word en dat werksrotasie geïmplementeer word om die vibrasie blootstelling van dié individue te beperk. Dit is bevind dat die taak waarvoor die voertuie gebruik word, sowel as die operasionele omstandighede, ’n noemenswaardige invloed op heel-liggaam vibrasie het. ’n Geskikte meettydperk vir verskillende tipes voertuie is statisties geïdentifiseer en dit is bevind dat meettydperke langer as 30 min en 60 min voldoende is om heel-liggaam vibrasie te meet met meetfoute kleiner as 25% (voldoende akkuraatheid) en 12.5% (gewenste akkuraatheid) onderskeidelik.

La thèse concerne la prévision du comportement dynamique non linéaire d’équipements optique. Les travaux de recherche menés se concentrent sur la simulation des phénomènes vibratoires en jeu, afin de prévoir la réponse harmonique de l’équipement. Ces travaux ouvrent ainsi la voie à des préconisations d’évolutions dans la conception mécanique du projecteur pour augmenter sa durabilité et le confort de vision. En effet les essais pratiqués montrent que de forts niveaux de vibrations endommagent les composants du projecteur et détériorent la stabilité du faisceau d’éclairage. Afin d’éviter de telles nuisances, la conception du projecteur doit être adaptée grâce à un modèle mécanique qui intègre des comportements non linéaires causés essentiellement par les liaisons pour prévoir le mieux possible les niveaux de vibrations du projecteur embarqué. L’état de l’art est réalisé sur les comportements dynamiques non linéaires, les modèles et méthodes de résolution associés, puis les estimateurs existants de quantification des non linéarités. Les essais d’analyse modale réalisés mettent en évidence la présence de phénomènes non linéaires dus à de multiples causes (jeux-butées, frottements, stick-slip, …) localisées dans les liaisons réflecteur-boitier. Les caractérisations expérimentales menées sur les liaisons, délivrent des boucles efforts-déflexion qui montrent différents types de comportement non linéaire, aident au choix des modèles les plus pertinents et au calage de leurs paramètres. Les limites de validité des modèles de calculs linéaires sont déterminées par des critères formulés empiriquement. Les modèles non linéaires de liaison sélectionnés sont intégrés dans un modèle réduit à un puis à deux degrés de liberté d’un projecteur. La réprésentativité du modèle est évaluée sur la base des analyses modales mesurées du projecteur. Les équations décrivent le comportement dynamique de projecteur et les non linéarités sous l’hypothèse de régime stationnaire. La méthode de balance harmonique associée à une technique de continuation par longueur d’arc résout rapidement les équations et détermine avec précision les réponses dynamiques établies. L’étude est complétée par l’analyse de stabilité selon la théorie de Floquet qui met en évidence la présence des branches de solutions stables ou instables. Enfin des réponses harmoniques sont calculées avec un modèle aux éléments finis du projecteur complet. Les calculs sont basés sur l’identification des modes qui reposent sur la répartition des masses dans la structure, la nature des liaisons. Des études d’influence sont réalisées. Les paramètres étudiés sont les raideurs et précontraintes de contact, le coefficient de frottement, l’amortissement introduit. Leurs impacts sur les niveaux des vibrations sont quantifiés ce qui amène au recalage du modèle éléments finis pour améliorer les résultats modaux du projecteur automobile et sa réponse harmonique forcée.

▼ Dielectric, elastic, and piezoelectric constants, and their corresponding losses in piezoelectric materials are defined under constant conditions of two categories; namely, intensive (i.e., E, electric field or T, stress), and extensive (i.e., D, dielectric displacement or x, strain) ones because of the electromechanical coupling effect. In the conventional IEEE Standard methods, only the intensive loss factors can be measured directly in the piezoelectric k31 mode rectangular plate specimen, while only the extensive loss factors can be measured directly in the k33 mode rod specimen. Then, the corresponding extensive or intensive parameters were derived indirectly from the coupling factor k31 or k33, and the so-called “K” matrix. However, the extensive loss parameters, calculated through this indirect method, could have large uncertainty, due to the error propagation in the calculation. In order to overcome this problem in lead-zirconate-titanate (PZT) k31 mode rectangular plate ceramics, extensive losses should be measured separately from the measurable intensive ones. We propose a new mechanical-excitation methodology, using a non-destructive testing approach by means of a partial electrode configuration of the PZT specimen, instead of the conventional full electrode configuration. For this purpose, a non-electrode (NE) sample was prepared, where the electrode covered only 10% of the top and bottom surfaces at the center to actuate the whole sample, and also monitor the responding vibration. The admittance spectrum of this sample corresponds to PZT properties under dielectric displacement D constant condition. Furthermore, ceramics with partial-electrodes (PE) were also prepared to create short and open circuit boundary conditions, attributing to resonance and anti-resonance modes. In the proposed way, we were able to measure both intensive and extensive elastic compliances and mechanical losses directly for the first time. The accuracy of this new method is compared with the conventional measurements by use of indirect calculations. The preliminary results (by neglecting the 10% actuator part difference at this point) were obtained, which were in good agreements (less than 3% difference) with the previous indirect method. Furthermore, we derive the exact analytical solution by considering the actuator part for calculating the resonance vibration mode and mechanical quality factors in a partial non-electrode sample, parametrically, with respect to “a”, the portion of the middle electrode. This is achieved by solving the dynamic and constitutive equations in a composite bar with both electrode (intensive losses) and non-electrode (extensive losses) boundary conditions. The result suggests that the almost accurate value of the extensive elastic compliance and mechanical loss can be obtained even for a specimen up to a = 0.4 (i.e., 40% covered by the electrode). This analytical solution for the partial electrode samples has the benefit of being more precise and simple to use, comparing with the other ones, such as… Advisors/Committee Members: Kenji Uchino, Thesis Advisor/Co-Advisor.

O presente trabalho reúne elementos para a análise dos principais problemas e dificuldades inerentes à implementação de um dispositivo para a aferição de velocímetros de veículos automotores, de forma a atender a legislação prevista no código nacional de Trânsito, determinada pela Portaria n.º 115 de 1998, que define erros máximos permitidos para velocímetros de ± 5km/h para velocidades de até 100km/h e de ± 5% para velocidades acima de 100km/h. Inicialmente são apresentados e comparados os principais métodos de medição de velocidade abordados na literatura. A partir desta análise, é implementado um método inovador decorrente do efeito de escorrimento ou blur, onde, através do estudo das características e regularidades contidas em uma única imagem borrada, será determinada a velocidade da superfície em análise. A partir de uma bancada que simula o solo em movimento e, utilizando-se uma câmera CCD (Charge Coupled Device) e um frame grabber, fez-se a aquisição de imagens da superfície asfáltica em movimento. A informação de velocidade pôde então ser determinada, através da análise das regularidades contidas na imagem dinâmica devido ao efeito de escorrimento ou efeito blur. Obteve-se resultados suficientes para a aferição de velocímetros, com erros máximos abaixo de 5%. A técnica desenvolvida e avaliada na prática através de uma bancada que simula o asfalto em movimento, demonstrou uma precisão de 0,8% numa faixa de velocidades de 0 a 20km/h , de 1,5% numa faixa de velocidades de 20 a 60km/h e de 2,5% numa faixa de velocidades de 60km/h a 80km/h. Finalmente foram investigados os fatores preponderantes que limitaram os erros nesta ordem de grandeza.

This work gathers elements for the study and analysis of the main problems and difficulties inherents to the implementation of a device to the gauging of a speedometer of automotive vehicles, in order to meet the foreseen legislation described by the governmental decree nº 115 from 1998, which defines the maximum allowed error for speedometers of ± 5km/h for speeds till 100km/h and ± 5% for speeds above 100km/h. From this study, a new method, based on the blur effect, is proposed. In the method, the speed of the target surface is determined by analyzing the characteristics and regularities contained in a single blurred image. Starting from a device that simulates the soil movement and, using a CCD (Charge Coupled Device) camera and a frame grabber, the acquisition of images of the moving asphalt surface was done. The information of speed then could be determined, through the study of the regularities contained in the dynamic image due to the blur effect. The necessary results for the gauging have been achieved with success, with precision below 5%. The developed and evaluated technique in practice through a device that simulates the asphalt in movement has demonstrated a precision of 0,8% in a range of speeds from 0 to 20km/h, 1,5% in a range of speeds from 20km/h to 60km/h and 2,5% in a range of speeds from 60km/h to 80km/h.

Dans les systèmes mécaniques ou mécatroniques, les actionneurs sont les composants utilisés pour convertir l’énergie d’entrée, généralement l’énergie électrique, en tâche mécanique telles que le mouvement, la force ou une combinaison des deux. Actionneur analogique et actionneur numérique sont les deux types d’actionneurs les plus communs. Les actionneurs numériques possèdent les avantages du contrôle en boucle ouverte, faible consommation d’énergie par rapport aux actionneurs analogiques. Cependant, les actionneurs numériques présentent deux inconvénients majeurs. Les erreurs de fabrication de ces actionneurs doivent être contrôlées précisément parce que, contrairement à des actionneurs analogiques, une erreur de fabrication ne peut pas être compensée par la loi de commande. Un autre inconvénient est leur capacité à réaliser les tâches continues en raison de leur corse discrète. Un assemblage de plusieurs actionneurs numériques peut néanmoins réaliser des tâches multiples discrètes. Cette thèse porte sur la caractérisation et l’optimisation d’une conception expérimentale actionneurs tableau numériques pour l’application planaire de transport. Le premier objectif principal de la présente thèse est axé sur la caractérisation de l’ensemble des actionneurs existants et aussi une application planaire de transport sur la base du tableau des actionneurs. A cette fin, une modélisation de la matrice des actionneurs essais expérimentaux ont été effectués afin de déterminer l’influence de certains paramètres sur le comportement des actionneurs de tableau. Le deuxième objectif est de concevoir une nouvelle version du tableau actionneurs sur la base de l’expérience du premier prototype. Une optimisation de la conception a ensuite été réalisée en utilisant des techniques d’algorithmes génétiques tout en tenant compte de plusieurs critères.

In mechanical or mechatronical systems, actuators are the components used to convert input energy, generally electrical energy, into mechanical tasks such as motion, force or a combination of both. Analogical actuator and digital actuator are two common types of actuators. Digital actuators have the advantages of open-loop control, low energy consumption and etc compared to analogical actuators. However, digital actuators present two main drawbacks. The manufacturing errors of these actuators have to be precisely controlled because, unlike to analogical actuators, a manufacturing error cannot be compensated using the control law. Another drawback is their inability to realize continuous tasks because of their discrete stroke. An assembly of several digital actuators can nevertheless realize multi-discrete tasks. This thesis focuses on the experimental characterization and optimization design of a digital actuators array for planar conveyance application. The firs main objective of the present thesis is focused on the characterization of the existing actuators array and also a planar conveyance application based on the actuators array. For that purpose, a modeling of the actuators array and…

L'étude proposée porte sur l'adaptation d'une méthode de mesure optique à lamesure de la topologie d'objet de grandes dimensions et à une distance de travail proche. Laméthode optique utilisée est la projection de franges car elle permet l'étude de grands objets.Dans un premier temps, des essais expérimentaux ont été réalisés pour évaluer l'exactitudedu développement actuel ; ce dernier utilisant une analyse de franges s'appuyant sur lacombinaison d'une méthode quasi-hétérodyne utilisant une transformation de Fourier etd'une méthode de code gray.Après avoir quantifié les erreurs et déterminé leurs sources, le choix dudéveloppement d'une procédure d'étalonnage et de nouvelles équations associées à cetteprocédure se sont imposés. Le nouvel étalonnage est quant à lui basé sur une interpolationpolynomiale de points définissant un volume de grandes dimensions. Un objet étalon a étéspécialement conçu pour cette procédure de calibration. Pour évaluer l'erreur du à lacalibration, une étude systématique de cas de polynômes dont le plus haut degré varie de 1à 4 a été effectué. Cette approche a permis de déterminer le degré optimal du polynôme àutiliser. Dans le meilleur cas, l'estimation de l'erreur a permis d'évaluer la précision del'étalonnage à 1 mm sur un objet de 2 m évalué à une distance de 2 m.La méthode a été par la suite appliquée, dans un cadre industriel à l'étude deflotteurs et dans un cadre médical à l'étude du relief de la paroi abdominale. D'un point devue médical, cette méthode permet d'obtenir rapidement et facilement la morphologie ducorps humain. Elle permet aussi d'effectuer un meilleur suivi des pathologiesmorphologiques des patients.

The proposed study deals with the adaptation of an optical method to themeasurement of large objects at a low working distance. The optical method used is thefringe projection technique allowing the study of large objects. At first, experimental trials hasbeen used to evaluate the accuracy of the actual development combining the phase shiftingmethod using a Fourier transform and the gray code technique.When the errors have been quantified and their origins determined, the developmentof a calibration procedure and new associated equations have been chosen. The newcalibration is based on polynomial interpolation of points defining a volume of largedimensions. A tested object was designed specifically for this calibration procedure. Toestimate the calibration error, a systematic study of polynomials cases is performed. Thehighest degree of those cases varies from 1 to 4. This approach allows the determination theoptimal polynomial degree to be used. In the best case, the estimation of the error allows theevaluation of the calibration accuracy of about 1 mm for an object of 2 m large, measured ata distance of 2 m.The method has been subsequently applied, in an industrial setting, to the study offloats and in a medical setting to the study of the relief of the abdominal wall. From a medicalpoint of view, this method gives a rapid and easy access to the topology of human body.…

Immediate occupancy and functionality of critical facilities including hospitals, emergency operations centers, communications centers, and police and fire stations is of utmost importance immediately after a damaging earthquake, as they must continue to provide fundamental health, emergency, and security services in the aftermath of an extreme event. Although recent earthquakes have proven the acceptable performance of the structural system in such buildings, when designed according to recent seismic design codes, in many cases damage to the nonstructural components and systems was the main cause of disruption in their functionality. Seismic isolation is proven to be an effective technique to protect building structures from damaging earthquakes. It has been the method of choice for critical facilities, including hospitals in Japan and the United States in recent years. Seismic isolation appears to be an ideal solution for protecting the nonstructural components as well. While this claim was made three decades ago, the supporting research for freestanding (unanchored) equipment and contents (EC) is fairly new. With the focus on freestanding EC, this study investigates the seismic performance of sliding and wheel/caster-supported EC in fixed-base and base-isolated buildings. The study adopts a comparative approach to provide a better understanding of the advantages and disadvantages of using each structural system. The seismic response of sliding EC is investigated analytically in the first part of the thesis, while the response of EC supported on wheels/casters is examined through shake table experiments on two pieces of hospital equipment. The study finds base isolation to be generally effective in reducing seismic demands on freestanding EC, but it also exposes certain situations where isolation in fact increases demands on EC. Increasing the frictional resistance for sliding EC or locking the wheel/casters in the case of wheel/caster-supported EC is highly recommended for EC in base-isolated buildings to prevent excessive displacement demands. Furthermore, the study suggests several design probability functions that can be used by practicing engineers to estimate the peak seismic demands on sliding and wheel/caster-supported EC in fixed-base and base-isolated buildings.

L'objectif de cette thèse est de contribuer à la compréhension de l'interaction entre des sollicitations de haute fréquence tangentielles et le déclenchement du glissement macroscopique, ainsi que la dynamique frictionnelle subséquente. Le travail est basé sur une approche expérimentale permettant d'étudier, à des fréquences ultrasonores, les propriétés élastiques et dissipatives de contacts sphère-plan en régime linéaire et non-linéaire. La méthode consiste à mesurer les caractéristiques de la résonance d'un piezoélectrique (fréquence de résonance et facteur de qualité) modifiées par l'établissement d'un contact mécanique. Le seuil de glissement est ajusté par le contrôle de la nature moléculaire de l'interface frictionnelle, constituée de films nanométriques greffés ou déposés par spin-coating. Nous commençons par étudier les propriétés physiques et mécaniques en régime linéaire de ces interfaces contrôlées. Ensuite, nous évaluons l'influence de l'amplitude des oscillations sur le l'angle de repos d'une sonde placée sur un plan incliné. Lorsque l'amplitude augmente, le seuil de glissement est abaissé quelle que soit la polarisation des oscillations. L'effet des vibrations est de diminuer la surface effective sur laquelle est appliquée la contrainte seuil statique, ce qui diminue la force seuil. Nous discutons de ces résultats à l'aide interprétation basée sur l'énergie vibratoire, qui jouerait un rôle proche d'une température effective dans un diagramme de « jamming ».Ensuite, nous étudions le comportement de contacts sphère-plan à de très hautes amplitudes oscillatoires. Nous observons un régime micro-glissement partiel au cours duquel le comportement du contact oscille entre micro-glissement partiel et total. Aux plus hautes amplitudes, les oscillations provoquent une fracture interfaciale et le rayon de contact diminue. Enfin, l'application d'oscillations tangentielles augmente la vitesse de glissement d'un patin soumis à une force constante. Dans le cas d'un film interfacial macromoléculaire, nous discutons des diverses interprétations possibles aux échelles microscopiques

The aim of this work is to bring new insights to the understanding of the interaction between high frequency tangential vibrations and the macroscopic triggering of sliding, as well as the subsequent frictional dynamics. This experimental work is based on a method that allows studying, at ultrasonic frequencies, the elastic and dissipative characteristics of sphere-plane contacts, in linear and non-linear regimes. The method relies on the measurement of the resonance frequency and the quality factor of a quartz, which are modified by the mechanical contact with a probe. The sliding threshold is adjusted by the control of the molecular nature of the frictional interface, which can be either grafted or spin-coated onto the quartz. We first characterize the physical and mechanical properties of the various interfaces in the linear regime. Then, we study the effects of the oscillation amplitude on the angle of repose of the probe in contact…

▼ This dissertation begins with the basic theory of Doppler radar system and motivation of this dissertation in Chapter 1. Challenges on the previous version of 5.8 GHz Doppler radar system will be discussed. For commercial purpose, the antenna coverage would be a challenge with a fixed-beam antenna. It demonstrates the misalignment issue under the test. An adaptive beam-steering antenna normally occupies a larger area. Chapter 2 introduces new adaptive beam-steering antenna with the focused beam. Better signal quality is achieved without manually alignment of an antenna. The new antenna size is the same as the conventional patch-array antenna. Misalignment of either transmitter or receiver antenna would degrade the signal quality. The antenna at Tx has larger effects on the misalignment due to the short-range re-radiation effect. In Chapter 3, a new method to detect the distance to the target with continuous wave (CW) radar and an adaptive beam-steering antenna is introduced. The system can concurrently detect the vibration and the distance to the target. To further reduce the size, system architecture with one shared transmitter and receiver antenna is demonstrated in Chapter 4. Novel miniature three-branchline coupler is designed and implemented to save the area. Wider bandwidth and smaller size are the benefits of this coupler. Chapter 5 integrates the Doppler vital-sign radar system with this new coupler into one printed circuit board (PCB). Only one antenna is used in the system to save the area and eliminate the coupling between transmitter and receiver antennas. System package is another possible issue to degrade the signal and is designed for our system. In Chapter 6, two hand-held devices integrated with the Bluetooth are designed and implemented. Low weight and low power consumption radar provide higher flexibility for mobile detection. In Chapter 7, this chapter summarizes the whole work and describes the future work in this field.

▼ Although medical progress and increased health awareness over the last 60 years have reduced death rates from cardiovascular disease by more than 75%, cardiovascular disease remains one of the leading causes of death, hospitalization, and cause of prescription drug use. Resting heart rate can act as an independent risk factor in cardiovascular mortality, while more detailed blood volume waveforms can offer insight on blood pressure, blood oxygenation, respiration rate, and cognitive stress. Electrocardiograms (ECGs) are widely used in the clinical setting due to their accurate measurement of heart rate and detailed capture of heart muscle depolarization, making them useful in diagnosis of specific cardiovascular conditions. However, the discomfort caused by the required adhesive patches, as well as the relatively high cost of ECG machines, introduces the need for an alternative system when only the resting heart rate is required. Photoplethysmography (PPG), the optical acquisition of blood volume pulse over time, offers one such solution. The pulse oximeter, a device which clips onto a thin extremity and measures the amount of transmitted light over time, is widely used in a clinical setting for heart rate and oxygen saturation measurements in cases where ECG is unnecessary or unavailable. Recently, a technique has been demonstrated to construct a blood volume pulse signal without the need for contact, offering a more sanitary and comfortable alternative to pulse oximetry. This technique relies on camera systems and is known as PPG imaging (PPGI). However, the accuracy of PPGI methods suffers in realistic environments with error incurred by motion, illumination variation, and natural fluctuation of the heart rate. For this reason, a statistical framework which aims to offer higher accuracy in realistic scenarios is proposed. The initial step in the framework is to construct a PPG waveform, a time series correlated to hemoglobin concentration. Here, an importance-weighted Monte Carlo sampling strategy is used to construct a PPG waveform from many time series observations. Once the PPG waveform is established, a continuous wavelet transform is applied, using the so-called pulselet as the mother wavelet, to create a response map in the time-frequency domain. The average of frequencies corresponding to the maximum response over time is used as the heart rate estimation. To verify the efficacy of the proposed framework, tests were run on two data sets; the first consists of broadband red-green-blue (RGB) colour channel video data and the second contains single channel near infrared video data. In the first case, improvements over state-of-the-art methods were shown, however; in the second case, no statistically significant improvement was observed.
