Abstract:

At Pozyx Labs, we do not believe that there exists a single technology for accurate indoor localization. Instead, the solution will come from an intelligent combination of many different technologies. We have created a positioning platform that combines ultra-wideband technology with a myriad of inertial sensors. By employing sensor fusion the disadvantages of each sensor separately can be mitigated and accurate indoor positioning becomes possible. The Pozyx system is compatible with the popular Arduino platform and is very easy to use. This allows for anyone, from a researcher, a business, to a creative mind to start with their positioning application in a matter of minutes.

Abstract:

Indoor localization solutions are of great interest to industry. However, information regarding realistic performances of existing systems in different environments is scarce. This presentation discusses the lack of objective evaluation metrics for localization solutions, discusses how these metrics are influenced by environmental factors such as the wireless environment and gives an overview of standardization efforts towards fair and comparable evaluations of localization solutions.

Abstract:

StickNTrack provides an ultra-low power GPS tracker built for the upcoming low-power, long-range networks.  StickNTrack is as easy as a sticker and provides up to 85.000 position updates directly broadcasted to the cloud on only 3 AA batteries. StickNTrack allows to connect a whole new range of non-powered assets in an economical viable way, creating new opportunities of efficiency optimisation, managing risks and turning internet of things to the economy of things.

Abstract:

The SINS SBO project focuses on the deployment of wireless acoustic sensor networks (WASNs) to monitor activity in a certain area: e.g., WASNs can be installed in the homes of aging people to monitor their behavioral patterns (to detect mild cognitive decline), or to respond to emergency situations (e.g., a cry for help). A great addition to this kind of monitoring applications is the knowledge of the location of the detected event. However, the main drawback of these WASNs, that typically rely on battery-powered sensors, is the energy consumption, that can drastically reduce their lifetime. We show how we can implement energy-efficient acoustic localization and explain the principles of the techniques that can be deployed, to localize unknown sound sources, i.e. Time-Difference of Arrival (TDOA) and Angle of Arrival (AOA).

Abstract:

With the increased usage of LED for illumination purposes, a new way of communication is on the horizon: Visible Light Communication. The idea is that by modulating the light stream at a frequency above the flicker fusion threshold of the human eye, we are able to sent information, on top of the illumination function of the LED. But what are the challenges, opportunities and what is the added value of this technology with regard to the ubiquitous RF-based communication networks? Nobby Stevens from the research group DraMCo of the KU Leuven will try to answer these questions in this talk.
