Study design of embedded electronics systems with a focus on applications where computing electronics, imaging detectors and image analysis is combined.

We study design of embedded electronics systems and with a focus on applications where computing electronics, imaging detectors and image analysis is combined. These embedded visual sensor systems are sometimes mechanically integrated with products that we often use in our daily life.

Vision based safety systems in modern cars is one good example. 3-dimensional inspection of logs in forest machinery or detection of particles in hydraulic oil is another example of industrial usage. Battery powered systems having long expected time of operation or high speed real-time systems requires careful optimization. Requirements on design metrics such as cost, speed, latency, power, size and even long lifetime maintainability becomes challenging for the designer. We are seeking deeper knowledge on how to optimize embedded systems for mentioned metrics. We are seeking better knowledge about applications for visual sensor systems and their usage.

Flis - Characterization of wood disintegration processes

virke, ytsnitt

The condition of cutting tools used in a wood disintegration process has a large impact on the quality of the products. Today we don’t know how long the intervals for replacement of worn out tools should be. This project aims at gaining knowledge for how process parameters for wood disintegration are related.

FOGGY

Fältstudie i Klövsjö

In order to determine icing conditions and to make icing forecast information it is required to know the air content of liquid water, Liquid Water Content (LWC) and droplet size, Median Volume Diameter (MVD).

Method for Cost Optimized Volumetric Object Monitoring Systems

Vindkraft örn övervakning Gotland

In this project researchers will investigate the requirements for VSN node architecture and deployment topology for remote outdoor monitoring. The goal is to find a cost optimized design constrained limited resources. Through close collaboration with industrial partners researchers will provide the industry with a tool for predicting future activity within a volume. Although this project focuses on monitoring wind farms and flying birds’ activities, the result are applicable in other fields.

SURF - Surface characterization of industrial large area products

Industri

The paper- and paperboard industries are undergoing a transition in terms of product specializations. A decreasing interest for Newspaper and harder competition in paperboard products forces the paper- and paperboard industries to start producing new products, where there is even higher demand on surface characteristics, since most products will undergo high quality print. This project will attempt to bridge the gap of modern industrial measurement needs for surface characterization.
