Resumo:

This work proposes the use of integrated high-power InGaN/GaN multiple-quantum-well flip-chip blue micro light-emitting diode (μ-LED) arrays on an AlGaN/GaN-based heterojunction field-effect transistor (HFET), also known as a high electron mobility transistor (HEMT), for various applications: underwater wireless optical communication (UWOC) and smart lighting. Therefore, we demonstrate high-power μ-LED-on-HEMT arrays that consist of 32 × 32 pixelated μ-LED arrays and 32 × 32 pixelated HEMT arrays and that are interconnected by a solder bump bonding technique. Each pixel of the μ-LED arrays emits light in the HEMT on-state. The threshold voltage, the off-state leakage current, and the drain current of the HEMT arrays are −4.6 V, <~1.1 × 10−9 A at gate-to-source voltage (VGS) = −10 V, and 21 mA at VGS = 4 V, respectively. At 12 mA, the forward voltage and the light output power (LOP) of μ-LED arrays are ~4.05 V and ~3.5 mW, respectively. The LOP of the integrated μ-LED-on-HEMT arrays increases from 0 to ~4 mW as the VGS increases from −6 to 4 V at VDD = 10 V. Each pixel of the integrated μ-LEDs exhibits a modulated high LOP at a peak wavelength of ~450 nm, showing their potential as candidates for use in UWOC.

This paper analyses the trend, design fundamentals, and design principles of contemporary character design from digital game. It discusses that even though the design styles of today’s digital art era are flourishing with diverse thinking and visual approach, the classic pixel art style will never go out of style. The fundamental element of artistic design in pixel art style is a single element, a pixel. Many designers prefer using the single pixel style as the fundamental element of their artistic design, which has led to the creation of various intriguing design categories. Despite the prevalent use of full high-definition 3D rendering images in contemporary digital game design, the pixelated style remains a timeless tribute to the classics with an enduring impact, given its promising development prospects. Pixelated design is now being applied to practice by more designers and artists, and it has gradually become a unique form of artistic visual expression.

Digital cameras obtain color information of the scene using a chromatic filter, usually a Bayer filter, overlaid on a pixelated detector. However, the periodic arrangement of both the filter array and the detector array introduces frequency aliasing in sampling and color misregistration during demosaicking process which causes degradation of image quality. Inspired by the biological structure of the avian retinas, we developed a chromatic LED array which has a geometric arrangement of multi-hyperuniformity, which exhibits an irregularity on small-length scales but a quasi-uniformity on large scales, to suppress frequency aliasing and color misregistration in full color image retrieval. Experiments were performed with a single-pixel imaging system using the multi-hyperuniform chromatic LED array to provide structured illumination, and 208 fps frame rate was achieved at 32 × 32 pixel resolution. By comparing the experimental results with the images captured with a conventional digital camera, it has been demonstrated that the proposed imaging system forms images with less chromatic moiré patterns and color misregistration artifacts. The concept proposed verified here could provide insights for the design and the manufacturing of future bionic imaging sensors.

Cadmium zinc telluride (CdZnTe) detectors are known to suffer from polarization effects under high photon flux due to poor hole transport in the crystal material. This has led to the development of a high-flux capable CdZnTe material (HF-CdZnTe). Detectors with the HF-CdZnTe material have shown promising results at mitigating the onset of the polarization phenomenon, likely linked to improved crystal quality and hole carrier transport. Better hole transport will have an impact on charge collection, particularly in pixelated detector designs and thick sensors (>1 mm). In this paper, the presence of charge sharing and the magnitude of charge loss were calculated for a 2 mm thick pixelated HF-CdZnTe detector with 250 μm pixel pitch and 25 μm pixel gaps, bonded to the STFC HEXITEC ASIC. Results are compared with a CdTe detector as a reference point and supported with simulations from a Monte-Carlo detector model. Charge sharing events showed minimal charge loss in the HF-CdZnTe, resulting in a spectral resolution of 1.63 ± 0.08 keV Full Width at Half Maximum (FWHM) for bipixel charge sharing events at 59.5 keV. Depth of interaction effects were shown to influence charge loss in shared events. The performance is discussed in relation to the improved hole transport of HF-CdZnTe and comparison with simulated results provided evidence of a uniform electric field.

En 2008, pour la première fois toutes les fonctions d’éclairage avant d’un véhicule sont entièrement à LEDs. Cette source de lumière a ouvert l'âge d'or de l'éclairage automobile par la basse consommation électrique, l’efficacité, la fiabilité, la haute luminosité, la compacité, ainsi que la rentabilité. Ces qualités lui ont permis de gagner la majorité des parts de marché dans l’automobile.La miniaturisation de la LED a permis la pixellisation du faisceau lumineux. Cela améliore davantage la sécurité routière. En effet, éclairer la route sans éblouir les autres usagers est devenu possible avec cette technologie. En outre, le besoin d'éclairage évolue avec l'arrivée de la voiture autonome. C’est alors que les technologies des LEDs pixélisées représentent des perspectives dans le domaine de l’éclairage pour les capteurs, et même dans la communication par la projection des pictogrammes et/ou l’écriture sur la route. Un second axe de recherche sera traité dans cette thèse. Il consiste à étudier les LEDs rouges avec luminophore pour les fonctions de signalisation arrière en automobile.De nouveaux mécanismes de défaillances vont faire surface, dû à ces nouveaux profils de mission et les nouvelles techniques de fabrication des LEDs immatures. Un besoin critique d’une démarche scientifique pour définir et exécuter un plan de tests et des caractérisations électriques, optiques, physiques et thermiques de ces nouvelles technologies.Les objectifs principaux de ces travaux de thèse seront de développer des nouvelles méthodes, des nouveaux bancs de caractérisations Opto-Électro-Thermiques et d’investiguer les modes et les mécanismes de défaillances liés aux processus de fabrication, géométries, matériaux de composition et aux nouveaux profils de mission des systèmes d'éclairage
In 2008, all front lighting functions of a vehicle are based on full LEDs for the first time. This light source opened the golden age of automotive lighting through low power consumption, efficiency, reliability, high brightness, compactness, as well as cost efficiency. These qualities have enabled it to gain the majority of the automotive market share.The miniaturization of the LED made possible the light beam pixelization. This further improves road safety. Indeed, lighting the road without glairing other users has become possible with this technology. In addition, lighting needs are changing with the arrival of the autonomous car. This is when pixelated LED technologies represent prospects in the field of lighting for sensors, and even in communication through the projection of pictograms and / or writing on the road.A second research axis will be dealt with in this thesis. It consists of studying red LEDs with phosphor for automotive rear signaling functions.New failure mechanisms will emerge, due to these new mission profiles and new techniques for manufacturing immature LEDs. A critical need for a scientific approach to define and execute a test plan and electrical, optical, physical and thermal characterizations of these new technologies.The main objectives of this thesis will be to develop new methods, new Opto-Electro-Thermal benchs’ characterizations and to investigate the modes of failure mechanisms related to manufacturing processes, geometries, composition materials and to new lighting systems mission profiles

Origami is a traditional Asian fine art of creating three-dimensional structures by folding paper. Recently, engineers have started to exploit the functional advantages of foldable structures. Formal representations of origami structures are limited. Most of the origami research describes an origami structure by providing the geometric properties of creases and vertices. This paper proposes a novel representation of an origami structure by describing the faces. An origami sheet is first pixelated with evenly distributed cellular agents, referred to as cells. Pixelization makes the origami structurally analogous to an LED matrix screen, with each of the cells being one LED pixel on the screen. Every cell will possess two key properties that contribute to determine the entire pattern: the cell type, which is analogous to the color of the LED; and the cell size, which is analogous to the light intensity of the LED. Therefore, a collection of cells with the same cell type (color) could represent the rough profile of an origami face, while the sizes of the cells are used to determine the face borders.. Creases and vertices can be subsequently determined by attaining the precise borders among faces. In this paper, we will also propose a crease restoration algorithm to determine the face borders and creases that then enable a fold to the final origami shape. The novel pixelated multicellular representation of origami enables new computational origami design methods as well as new self-folding origami structures.

Abstract Due to the high cost of equipment and lack of trained personnel, manual palpation is a preferred alternative breast examination technique over mammography. The process involves a thorough search pattern using trained fingers and applying adequate pressure, with the objective of identifying solid masses from the surrounding breast tissue. However, palpation requires skills that must be obtained through adequate training in order to ensure proper diagnosis. Consequently, palpation performance and reporting techniques have been inconsistent. Automating the palpation technique would optimize the performance of self-breast examination, optimize clinical breast examinations (CBE), and enable the visualization of breast abnormalities as well as assessing their mechanical properties. Various methods of reconstructing the internal mechanical properties of breast tissue abnormalities have been explored. However, all systems that have been reported are bulky and rely on complex electronic systems. Hence, they are both expensive and require trained medical professionals. The methods also do not involve palpation, a key element in CBE. This research aims in developing a portable and inexpensive automated palpable system that mimics CBE to quantitatively image breast lumps. The method uses a piezoresistive sensor equipped probe consisting of an electronic circuit for collecting deformation-induced electrical signals. The piezoresistive sensor is made by spraying microwave exfoliated graphite/latex blend on a latex sheet. Lumps can be detected by monitoring a change in electrical resistance caused by the deformation of the sensor which is induced by abnormalities in the breast tissue. The electrical signals are collected using a microcontroller and a pixelated image of the breast can be reconstructed. The research is still in progress, and this report serves as proof of concept testing by pressing the probe with hand pressure and reconstructing the electrical signals using Microsoft Excel. Four maps were created for qualitatively analyzing the result. The pressure maps clearly display areas where pressure was applied, indicating the potential of the probe in detecting breast tissue abnormalities. The pressure maps show the feasibility for using such a sensor for the application in CBE. Furthermore, a sensor such as this is also possible of detecting the depth and size of masses within breast tissue, which, may lead to a more accurate diagnosis. Better manufacturing, accuracy, precision, and realtime data feeds are areas of future consideration for this project. This project involves knowledge and applications from mechanical, electrical, computational, and materials engineering.
