Aug 03, 2023 | 4:00 PM CET

About Topic: Positioning systems have gained paramount importance for many different productive sector; however, traditional systems such as Global Positioning System (GPS) have failed to offer accurate and scalable solutions for indoor positioning requirements. Nowadays, alternative solutions such as fingerprinting allow the recognition of the characteristic signature of a location based on RF signal acquisition. In our work, a machine learning (ML) approach is selected in order to classify the RSSI information acquired by multiple scanning stations from TAG broadcasting messages. TinyML has been considered for this project, as it is a rapidly growing technological paradigm that aims to assist the design and implementation of ML mechanisms in resource-constrained embedded devices. This talk presents the design, implementation, and deployment of embedded devices capable of communicating and sending information to a central system that determines the location of objects in a defined environment. A neural network (deep learning) is trained and deployed on the edge, allowing the multiple external error factors that affect the accuracy of traditional position estimation algorithms to be considered. Edge Impulse is used as the main platform for data standardization, pre-processing, model training, evaluation, and deployment.

The IoT and the two sides of Sustainability | Carlo Boano

Mar 02, 2023 | 4:00 PM CET

About Topic: IoT systems are often portrayed as a key driver for sustainability and as an essential technology to achieve many of the seventeen United Nations’ sustainable development goals by 2030. Among others, IoT systems can help improving health and well-being, building smart cities, promoting a responsible production and consumption, increasing awareness and visibility into energy and resource usage, as well as facilitating access to clean energy. At the same time, sustainability is often not a concern during the design of an IoT system: several IoT gadgets are unnecessary, many IoT products become quickly obsolete, and poorly-performing IoT devices are quickly dismissed. As a result, IoT hardware often ends up as e-waste into landfill after a very short lifespan, which is worrying considering the magnitude of IoT devices expected in the next decade. In this talk, I will illustrate this paradox with concrete examples and highlight the need to maximize the usability and lifetime of IoT systems, presenting technical solutions that could help in this regard.

Toit, a modern framework for IoT | Florian Loitsch

Nov 03, 2022

About Topic: Modern microcontrollers, like the ESP32, are more powerful than the first Unix machines. Despite their speed, they are still treated like 8-bit microcontrollers from the 90s: by flashing monolithic applications on them. Individual components have no protections from each other, and the development process is brittle, since a change or bug in one part of the firmware could adversely affect the rest. This doesn’t need to be. In this presentation we will present Toit. A modern framework for IoT devices. A new language, virtual machine, and lots of libraries, work together to provide a great development experience with properties we generally expect from operating systems: memory separation, individual applications, ease of use with a high-level garbage-collected language, and fast development iterations.

About Speaker: Florian Loitsch did his PhD in compiler technologies, compiling Scheme to JavaScript. He was then hired by Google to work on V8 (Chrome’s JavaScript engine). He was part of the team that developed the Dart programming language, for which he was the technical lead for the Dart-to-Javascript compiler and later for the Dart libraries. Almost 5 years ago, he co-founded Toitware, where he has been developing and improving Toit since.
