Examples of research results

20

Sensor system and reliable data acquisition develpment has e.g. resulted in

a patented a method to determine the lactate threshold, a wireless ECG system, an alco-sensor principle, an optical sensor system measuring vascular

parameters, characteristics of textile electrodes, motion analysis sensor systems as gyroscopic-based alternative computer mouse.

Algorithm and signal processing development has resulted in a lab system

for microwave imaging and algorithms for inverse scattering problems to provide image reconstruction from experimental data, and algorithms for robust heart beat detection recorded by textile electrodes, algorithms for fall detection using built in sensors in a smart phone.

Intelligent decision support systems has developed systmes forcase based

reasoning with application in stress medicine, paincontrol (EU-FP7), and monitoring of drivers.

(21)

Examples of research results

21

Network capacity measurements and estimations resulting in

the TOPP method and improvements to the BART analysis method. This work has been done in coproduction with industry, in particular with Ericsson Research and Telia AB.

Dependable and predictable wireless networks

We have contributed to the design, implementation and analysis of wireless industrial control systems. We have improved wireless

communication in harsh industrial environments at the MAC layer and network layer.

Energy characteristics of wireless communication

We have investigated energy consumption issues for Bluetooth communication as well as more general energy consumption characteristics.
