IoT product design for dementia: HydrationCane (empowerment) & SoundReminiscence (wellbeing)

Self, James, Kim, Chajoong, Park, Youngwoo, Jung, Dooyoung 18 December 2019 (has links)
Adopting an internet-of-things product design approach, we present two concepts that respond to practical and emotional needs associated with changes in memory function. HydrationCane, a design to support improved hydration in people with early stage dementia, provides users opportunity to continue to engage in the outdoor pursuits of walking and climbing familiar within the design’s Korean use context. SoundReminiscence draws upon research on audio/music therapy and episodic memory to provide people living with dementia opportunity for reminiscent storytelling through technology enabled memory ques as bespoke sound files. Although differing in their focus, scope and aims the two concept designs indicate how an internet-of-things approach represents opportunities for the design of products that empower and enhance the lives of people living with dementia.

Cytroconnect – a cloud-based IOT-service as connectivity solution for electrohydraulic systems

Laube, Martin, Günder, Andreas, Bierod, Jan, Jesberger, Volker, Rauch, Stefan 25 June 2020 (has links)
Conventional electrohydraulic solutions integrate easily into modern machine concepts by utilizing field bus technology. Nevertheless, most use cases are limited to machine automation concepts. Integration into higher-level data and IoT systems is the key for positioning of electrohydraulic solutions within the factory of the future. CytroConnect is a new approach for the integration of electrohydraulic systems into IoT environments and the corresponding market offerings. Bosch Rexroth decided not only to integrate IoT-ready features like pre-installed sensor packages but also a modular automation concept providing decentralized intelligence with an open multi-ethernet interface. An edge-to-cloud connectivity stack operated by Bosch turns the target into a Connected Product. The convergence of physical and digital product can be realized. Based on that the digital service CytroConnect solves concrete holistic use cases like visualization and condition monitoring by offering a web-based dashboard of all relevant sensor data that is accessible everywhere. Modular paid add-ons offered as risk-free monthly subscriptions address further smart maintenance and prediction use cases.

Enhancing IoT Security Using 5G Capabilities

Makkar, Ankush January 2021 (has links)
Internet of Things (IoT) is an ecosystem comprises CT (Communication Technology),IT (Information Technology) and sometime OT (Operational Technologies) wheredifferent machines and devices can interact with each other and exchange useful datawhich can be processed using different IoT applications to take decisions and performrequired actions. Number of IoT devices and IoT networks are growing exponentially.Security is of utmost importance and without proper security implementation, IoTNetworks with billions of devices will be hacked and used as botnets which can createdisaster. The new IoT use cases cannot be realized using the current communicationtechnologies due to the QoS (Quality of Service) and business requirements. 5Gnetwork are designed keeping IoT use cases in mind and with the development of 5Gnetwork, it will be easier to implement more secured IoT network and enable differentIoT use cases which are not feasible today.To build the future IoT networks with 5G, it’s important to study and understand 5Gsecurity features. Security is perceived as one of the most important considerationwhile building IoT solutions and to implement 5G network for IoT solutions require anoverall understanding of 5G security features. In the thesis, work have been done toidentify the gap in the current research with respect to 5G security features anddescribe 5G features that will enhance IoT security. After identifying key 5G securityfeatures, the implementation of the identified 5G security features will be describedwith the 5G based smart grid and smart factory use cases. The key finding is howdifferent 5G security capabilities secure IoT communication and another importantfinding is that not all security capabilities are applicable to all IoT use cases. Hence,security capabilities to be used based on the 5G use case requirement.

Har digitalisering en hållbar framtid inom byggbranschen?- Avser byggproduktion / Does Digitalisation have a Sustainable Future in the ConstructionIndustry?

Erdal, Berke, Rashid, Srod January 2021 (has links)
Byggbranschen är idag en av få branscher där utvecklingen av digitalisering har gåttlångsamt. En anledning till detta är byggsektorns inställning till förändring eftersom den ansesvara konservativ. Bristen på digitalisering har visat sig medföra konsekvenser som ineffektivproduktivitet och onödiga kostnader.Syftet med studien var först och främst att informera om hur byggbranschen ser ut idag utifråndigitaliseringens synvinkel. Dessutom var målet att bidra med en kartläggning över de digitalaverktyg som används idag i produktionsfasen samt ge en förenklad bild av deras funktioner.Därtill var poängen även att bidra med lösningsförslag på hur byggproduktionen kundeeffektiviseras, detta i form av digitala verktyg som kunde tänkas standardiseras i framtiden.Rapporten har en kvalitativ metod där fokus låg på att kartlägga olika aktörers perspektivinom byggbranschen samt genomföra en informationsrik sökning från litteraturkällor. Detförstnämnda skedde genom enkätundersökningar. Informationen hämtades framförallt frånvetenskapliga rapporter men även artiklar och hemsidor.Resultatet visade att fördelarna överväger nackdelarna, där en hantering av verktygen på rättsätt visade sig ge en ökad produktivitet i produktionsfasen samtidigt som en minskning avbåde kostnad och tid. Nackdelarna beror på ekonomiska skäl i form av dyrainvesteringskostnader och att det krävs en upplärningsperiod. Avgränsningen iexamensarbetet var endast mot digitala verktyg som används i byggproduktion och enkätenbesvarades enbart av personer som jobbar inom Sveriges byggföretag.Slutsatsen som drogs var att digitalisering medför ett flertal positiva egenskaper som kaneffektivisera byggbranschen. / The construction industry is today one of few industries where the development ofdigitalisation has been slow. One reason for this is the construction sector's attitude to changeas it is considered conservative. The lack of digitalisation has been shown to result inconsequences such as inefficient productivity and unnecessary costs.The purpose of this study was to first and foremost inform about what the constructionindustry looks like today from the viewpoint of digitalisation. In addition, the goal was tocontribute knowledge about the digital tools used today in the production phase and provide asimplified depiction of its functions. Furthermore, the point was also to come up with solutionproposals on how construction-production can be made more efficient, this in the form offuture digital tools.The investigation has a qualitative method where the focus was on the perspective of differentpeople in the construction industry and conducting an information-rich search from literaturesources. The former was done with the help of surveys. The information was obtainedprimarily from scientific reports but also articles and websites.The results showed that the advantages outweigh the disadvantages where a handling of thetools in the right way proved to give an increased productivity in the production phase at thesame time as a reduction of both cost and time. The disadvantages are due to financial reasonsin the form of expensive investments and that an education was required. The limitation in theproject was to only cover digital tools used in construction-production and the survey wasexclusively answered by staff working in Sweden's construction sector.The conclusion that was drawn was that digitalisation can lead to a number of positivequalities that can benefit the construction industry.

Design and development of energy-efficient transmission for wireless IoT modules / Conception et développement d'une transmission écoénergétique pour les modules IoT sans fil

Shakya, Nikesh Man 06 February 2019 (has links)
L'Internet des objets (IoT) devrait interconnecter plus de 50 milliards d’objet d'ici à 2020. Avec l'IoT, une variété d’objets de différentes industries seront interconnectés à travers Internet. Avec un accent sur la gestion et le stockage des ressources énergétique et l'eau. L'IoT permet d’enrichir les services fournis par les distributeurs d’énergie à travers les smart-grid au-delà de la distribution, de l'automatisation et du contrôle. Les systèmes de gestion pour la domotique et les bâtiments intelligents aideront les consommateurs à surveiller et à ajuster leur consommation. Les compteurs intelligents fournissent ainsi un ensemble d’information permettant aux fournisseurs d’énergie de mettre en place des services plus intelligents pour l'ensemble de la chaîne de production d'énergie. L'objectif principal de ce projet de recherche doctorale est de développer des modules de communication très basse consommation. La consommation énergétique étant la plus grande contrainte pour les applications de compteurs intelligents. Les objets connectés alimentés par batterie tels que les capteurs et compteurs de gaz et d'eau sont concernés directement par la consommation en énergie de leur module de communication. Aujourd'hui, la plupart des solutions sans fil embarquées conçues pour capteurs alimentés ne sont pas compatible avec la pile protocolaire IPv6 afin d’économiser la consommation énergétique. Élaborer des technologies sans fil de l'IoT pour atteindre les objectifs de consommation d'énergie va démocratiser l’utilisation de ces technologies et aider les solutions de l’IoT à trouver leur place sur le marché. Ce doctorat débutera par: 1) Un état de l'art permettant d'examiner les solutions actuelles développées pour les réseaux de capteurs et des protocoles conçus pour les appareils alimentés par batterie. 2) Dans un deuxième temps en examinant les solutions Itron pour IPv6 réseau maillé. 3) La troisième phase sera la proposition et la conception d'une solution à faible consommation pour les modules sans fil et l'internet des objets. 4) Et enfin l’expérimentation et la validation des solutions proposées sur des plateformes d’expérimentations / The Internet of Things (IoT) is expected to grow to 50 billion connected devices by 2020. Within the IoT, devices across a variety of industries will be interconnected through the Internet and peer-to-peer connections as well as closed networks like those used in the smart grid infrastructure. With the global focus on energy and water management and conservation, the IoT will extend the connected benefits of the smart grid beyond the distribution, automation and monitoring being done by utility providers. Management systems for in-home and in-building use will help consumers monitor their own usage and adjust behaviors. These systems will eventually regulate automatically by operating during off-peak energy hours and connect to sensors to monitor occupancy, lighting conditions, and more. But it all starts with a smarter and more connected grid. Smart metering provides a base around which utilities can build up smarter advanced services for the whole chain of energy generation, transmission and distribution. The main objective of this doctoral research project is to come up with the IoT communication modules with very low consumption characteristics. The energy consumption is the most challenging issue for smart home and smart metering applications. The battery powered devices such as sensors and gas and water meters are concerned directly with the consumption of their communication module. Today most of the embedded wireless solutions designed for sensors and battery powered devices do not embed IPv6 stack in the communication module to have a basic hardware with low consumption. Elaborating IoT wireless technologies to achieve the tough energy consumption objectives imposed to them will boost up the spread of these technologies and help IoT to find its place in the market fast. This PhD program will start with: First) a state of the art and reviewing the current solutions developed for sensor networks and protocols designed for battery powered devices. Second) it continues by reviewing Itron solutions for IPv6 meshed network. Third) Design of a low consumption solution for IoT wireless modules and) finally test and experimentation on platform

Indiana University-Purdue University Indianapolis (IUPUI) / This project aims to develop a cloud-based platform that integrates sensors with business intelligence for real-time energy management at the plant level. It provides facility managers, an energy management platform that allows them to monitor equipment and plant-level energy consumption remotely, receive a warning, identify energy loss due to malfunction, present options with quantifiable effects for decision-making, and take actions, and assess the outcomes. The objectives consist of: 1. Developing a generic platform for the monitoring energy consumption of industrial equipment using sensors 2. Control the connected equipment using an actuator 3. Integrating hardware, cloud, and application algorithms into the platform 4. Validating the system using an Energy Consumption Forecast scenario A Demo station was created for testing the system. The demo station consists of equip- ment such as air compressor, motor and light bulb. The current usage of these equipment is measured using current sensors. Apart from current sensors, temperature sensor, pres- sure sensor and CO2 sensor were also used. Current consumption of these equipment was measured over a couple of days. The control system was tested randomly by turning on equipment at random times. Turning on the equipment resulted in current consumption which ensured that the system is running. Thus, the system worked as expected and user could monitor and control the connected equipment remotely.

The Characterisation and Continuous Measurement of Potential Harvestable Energy of an Environment

Bajwa, Diran January 2023 (has links)
This thesis is based around the use of energy harvesting in systems, specifically for a Bluetooth Low Energy (BLE) mesh testbed. This BLE mesh is located in a well lit lab and is currently powered by mains electricity. Systems such as the BLE mesh are considered Internet of Things (IoT). The market for these systems is rapidly expanding and in turn so is the energy use. Many systems are powered by battery, and the need to replace a battery with an energy harvesting system has arisen. This thesis will explore the possibilities to power a node in this mesh and introduce a level of intelligence to allow the system to better predict available energy to harvest. The lab the BLE mesh is in is characterised for potential energy sources. Light is chosen to be an exceptional power source, from here a lux metre is created from a photovoltaic (PV) cell. This PV cell would function as both the power for the system and provide a method to measure the current light intensity. This would help add a layer of intelligence to the system to allow future systems to better understand how much energy is available. This idea can be implemented in other harvesters as well. / Denna avhandling är baserad på användningen av energiskördning i ett system, specifikt i en Bluetooth Low Energy (BLE)-mesh. Denna BLE-mesh befinner sig i ett väl upplyst labb och är för närvarande strömdrivet genom huvudström. System som BLE-mesh anses vara en del av Internet of Things (IoT). Marknaden för dessa system expanderar snabbt och därmed ökar också energiförbrukningen. Många system är batteridrivna och det har uppstått ett växande behov av att ersätta batteriet med ett energiskördsystem. Denna avhandling kommer att utforska möjligheterna att strömförsörja en nod i denna mesh och införa en intelligensnivå för att förbättra systemets möjlighet att förutspå energi som är tillgänglig för att skördas. Labbet där BLE-meshen befinner sig karakteriseras för potentiella energikällor. Ljus valdes som en exceptionell kraftkälla, och därifrån skapas en luxmeter från en fotovoltaisk (PV) cell. Denna PV-cell ska fungera både som strömkälla för systemet och utgöra en metod för att mäta nuvarande ljusintensitet. Detta skulle bidra till att lägga till ett skikt av intelligens i systemet för att göra det möjligt för framtida system att bättre förutspå tillgänglig skördbar energi. Denna idé kan även implementeras i andra energiskördsystem.

Security and Privacy Concerns for IoTAdoption : A User Perspective

Mazvimba, Dennis January 2022 (has links)
The Internet of Things (IoT) is one of the most rapidly evolving technologies aroundthe globe that has changed the way people live due to the benefits that comes with itsadoption. However, they have been associated with privacy and security risks. Witha focus on technical mechanisms and a lack of attention to consumer concerns over along time, it is unsurprising that manufacturers lack an understanding of consumersecurity and privacy concerns. While there has been significant empirical researchwarranting consumer concerns, their perceptions remain afoot.The purpose of this study is to understand the consumer privacy and securityperceptions associated with adoption of IoT devices within a smart home. Without an understanding of the consumer perceptions on privacy and security issues, manu-facturers may not address these issues which may hinder the adoption of IoT. While a significant number of studies have shown the privacy and security issues surrounding IoT devices, they have only extended to technical issues, mostly from the manufac-turer’s perspective. Since security is a complex issue involving several stakeholders, these studies cannot be applied from a consumer perspective.In this study we adopt an interpretive philosophical orientation and a qualitativeapproach. In depth interviews are used to collect data from smart homeowners,investigating their perceptions of smart home privacy issues. We have identified threesignificant recurring themes that need to be addressed: ethical and regulatory issues,information control and ownership, and technology design issues.

[en] METACOMMUNICATION AND APPROPRIATION IN THE DESIGN OF THE INTERACTIVE INTERNET OF THINGS / [pt] METACOMUNICAÇÃO E APROPRIAÇÃO NO PROJETO DA INTERNET INTERATIVA DAS COISAS

BRUNO AZEVEDO CHAGAS 05 November 2020 (has links)
[pt] A Internet das Coisas (IoT, do inglês Internet of Things) refere-se à infraestrutura tecnológica emergente formada por objetos cotidianos e ambientes dotados de computação e conectividade a fim de fornecer serviços digitalmente enriquecidos e comportamentos responsivos no mundo físico. Como com toda tecnologia, nas pontas da IoT há as pessoas que projetam e as que usam essa tecnologia de alguma forma. Projetar a interação para a IoT apresenta desafios novos e antigos. Nesta tese, eu abordo dois deles, a metacomunicação e a apropriação. O primeiro tem a ver com as pessoas que projetam a IoT; o último, com as que usam. Aplicando a Engenharia Semiótica como uma lente teórica ao estudo da IoT, realizei seis estudos usando diferentes métodos cujos resultados foram combinados em três contribuições. Primeiro, proponho um modelo semiótico de apropriação de tecnologia como uma ferramenta epistêmica para apoiar projetistas a refletirem sobre como os usuários adotam a tecnologia de IoT. Segundo, proponho uma caracterização semiótica para a tecnologia da IoT como metacomunicação, chamada de engenharia semiótica de tecnologias multiníveis e multilaterais, uma ferramenta inicial para a aplicação de princípios e métodos de Engenharia Semiótica à tecnologia da IoT. Terceiro, minha abordagem de pesquisa foi generalizada em um macro-método para pesquisa em tecnologias inovadoras como uma alternativa útil para pesquisas onde há falta de consenso e/ou diversidade metodológica e epistemológica, como em novas tecnologias. Essas contribuições estendem os conhecimentos da Engenharia Semiótica como teoria e fornecem recursos poderosos para projetistas e pesquisadores refletirem sobre a tecnologia de uma maneira centrada no ser-humano, eu argumento. / [en] The Internet of Things (IoT) refers to the emerging technological infrastructure formed by everyday objects and environments endowed with computing and networking power in order to provide digitally enhanced services and responsive behaviors in the physical world. As with every technology, at the end points of the IoT, there are people designing and using this technology somehow. Designing interaction for the IoT presents old and new challenges. In this thesis, I address two of them, namely metacommunication and appropriation. The former has to do with the people who design the IoT; the latter, with those who use it. By applying Semiotic Engineering as a theoretical lens to the study of IoT technology, I conducted six studies using different research methods which results were combined in three contributions. Firstly, I am proposing a semiotic model of technology appropriation, which is proposed as an epistemic tool to support designers reflect on how users adopt IoT technology. Secondly, I am proposing a semiotic characterization of IoT technology as metacommunication called the semiotic engineering of multi-level and multi-sided technologies, as an initial framework for the application of Semiotic Engineering principles and methods to IoT technology. Thirdly, my research design was generalized into a macro-method for approaching innovative technologies research. I claim that it is an useful alternative in research domains where there is a lack of methodological and epistemological consensus and/or diversity, such as with new technologies. These contributions both extend the body of knowledge of semiotic engineering as a theory and provide powerful resources for designers and researchers to reflect on technology in a human-centered way, I argue.
