• 9:00 Introduction: goals of the project and tasks for the 1^st year (J.Spīgulis)
• 9:05 Acquisition of several monochromatic spectral images for skin chromophore mapping (A1.1.A, J.Spīgulis, I.Ošiņa)
• 9:20 Video-imaging under infrared illumination for cardiovascular monitoring (A1.1.b, O.Ļašuka, U.Rubīns)
• 9:35 Tissue assessment at the infrared spectral range (A1.1.c, G.Tunēns, I.Saknīte)
• 9:50 Improvements of the multimodal imaging prototype device „SkImager” (A1.3.d, J.Bauer, E.Kviesis-Kipge)
• 10:05 Summary and discussion

On April 11 – 18 within the Project No.1. „Development of technologies for cyber physical systems with applications in medicine and smart transport” researcher A.Hermanis, programmer E.Syundykov and lead researcher L.Seļavo participated in the International Conference “Information Processing in Sensor Networks” IPSN 2015 in Sietla (USA), which occurs within the framework of 5 world-class conferences event CSPWeek 2015.   IECS representatives participated in the conference in a number of demo sessions and localization challenge “Microsoft Indoor localization Competition” to demonstrate in the Institute developed network prototypes for human movement parameters monitoring and present a prototype for knee rehabilitation device in conference exhibition. More about conference here.

Activities

The project is building tools for wireless sensor development, including the testbed with sensor modules, that can be tested and profiled while deployed at the Institute of Electronics and Computer Science. The current activities include remote programming and remote boot support, configuration and service server development. There is also work being done for the mobile testbed that will be used for ITS research and systems validation.

The second aspect of the project involves applications of cyber physical systems for health care. THe researchers are developing a wearable and wireless heart monitor, currently in the prototype desin phase. Another prototype being developed and tested is the body dynamics sensor system containing several accelerometer and gyroscope modules that in concert can deliver a shape of body such as back or a knee joint in real time and assist in rehabilitation. Currently the back shape prototype is built and the new version is under development, including additional sensors for better precision.

The third area is intelligent transportation systems. The research group is in the process of developing a smart sensor interface for vehicle position and orientation in the environment, using such sensors as LiDAR Velodyne HDL-32E, RTK-GPS OXTS RT3003 and OXTS RT-Base-2. These devices are being adapted and tested for eventual participation in the Grand Cooperative Driving Challenge 2016. In addition, work is being done in the field of image processing and analysis, including object identification on a noisy backround for road analyisis in real time, as well as driver face image analysis for the signs of fatigue.
