ABN HaFreeS MVP Prototype. 01/01/2024 - 31/12/2024

Abstract

In this project we investigated during the first phase (IOF-POC ABN HaFrees Feasibility) whether it was possible to develop a hands-free kit for bicycles. The main goals here were ease of use and call quality at speeds above 10 to 15 km/h. To this end, we mapped the market, from which it became clear that the first focus should be on the functional user (i.e. the professional who wants to use his work-related commute by bike to call colleagues, customers, etc.). The first tests showed that a significant suppression of wind noise is possible using several techniques (selection of good microphones, the choice of an optimal arrangement of each individual microphone combined in an optimal configuration, appropriate shielding i.c.w. the right signal processing algorithms). The techniques on their own do not provide sufficient improvement, but the delta is sufficient so that the combination should allow for a quality conversation at 25km/h. In this second phase of the project, we want to develop a minium viable product (MVP) prototype, which should allow to (1) characterize the product on its main qualities, (2) benchmark the product against competing products, (3) set up tests in view of user feedback and (4) define the further direction of the valorization. An essential hurdle here is the intellectual protection of the technology.

ABN HaFreeS Feasibility. 01/09/2022 - 31/12/2023

Abstract

In this project, we take the first steps in the development a novel hands-free communication set for use on bicycles. The main advantages of our solution in comparison to current solutions are call quality and convenience. Call quality is our main selling point: wind noise, traffic noise and contact noise impede comfortable calling at a speed above 10-15 km/h with the current available technology; we aim to overcome these shortcomings using technology building blocks available in Cosys-lab that have matured in other application domains. We mainly focus on showing technology feasibility, initiating a market study and perform initial user outreach activities. We will also start preparing the design of an MVP prototype. These activities are an essential first step to determine if it is worthwhile to pursue the end goal of commercializing the solution in a spin-off. If the technology is shown to work and the valorisation potential lives up to our expectations, we will undertake further steps in later projects to develop a deep market insight, a convincing MVP prototype and a solid value chain. These elements are necessary to reach the end goal of starting a VC-funding-free spin-off, bootstrapping with funding gathered in a crowdfunding campaign.

Hydrophone Array Sensing as a Means for Subaqueous Monitoring. 01/04/2021 - 31/03/2022

Abstract

Over the last years CoSys Lab developed state of the art sonar sensors, sensor arrays, acoustic monitoring techniques and bioinspired sensing approaches, published them in high impact journals and successfully initiated industry collaborations. So far all the sensor systems were designed for airborne (ultra)sound, however, these systems can also be adapted to underwater acoustics and therefore broaden the field for applications both within research as in industrial collaborations. Therefore, we want to develop an underwater acoustics/sonar measuring device and need additional equipment (e.g. hydrophones, underwater speakers and data acquisition cards) that can provide us with ground truth benchmarking data in order to quantify the efficacy of our initial prototypes. We want to focus mainly on hydrophone arrays for bioacoustics research as we see here most potential for now, but in future our knowledge acquired in this project will help us to design 3D underwater sonar sensors.

3D sonar sensing for inland shipping applications.. 01/02/2020 - 31/01/2021

Abstract

In this project, we will evaluate the applicability of the eRTIS 3D sonar sensor in autonomous indoor shipping applications. We will collaborate with a supplier of indoor autonomous shipping solutions to provide an experimental platform which can be used to evaluate the sensing capabilities of the sensor setup. Furthermore, we will work on water-proofing of our technology, which is an important asset for the overall sensor performance.
