Analysis of tool heating in cold forging using thin-film sensorsK. C. Grötzinger, A. Schott, M. Rekowski, B. Ehrbrecht, T. Hehn, D. Gerasimov, M. Liewald International ESAFORM Conference, 19.-21. April 2023, Krakow, Poland show abstractData acquisition and data analysis to gain a better process understanding are one of the most promising trends in manufacturing technology. Especially in cold forging processes, data acquisition close to the deformation zone seems challenging due to the high surface pressure. Thus far, process parameters such as die temperature are mainly measured with state-of-the-art sensors, including standard thermocouples, which are integrated into the tooling system. The application of thin-film sensors has been tested in hot forging processes for local die temperature measurement. However, the process conditions regarding tribology and tool load in cold forging are even more difficult. In this contribution, the use of thin-film sensors, applied on a cold forging punch for cup backward extrusion, is subjected. The aim is to investigate the applicability of such thin-film sensors in cold forging with special emphasis on temperature measurement in cyclic forming processes. The thin-film sensor system and its manufacturing procedure by vacuum coating technology combined with microstructuring are described. With these thin-film sensors the cup backward cold extrusion of steel billets was investigated experimentally. Cyclic tool heating simulations with thermal parameter variations were performed as a reference to

Comparison of non-pulsating reflective PPG signals in skin phantom, wearable device prototype, and Monte Carlo simulationsM. Reiser, T. Müller, K. Flock, O. Amft, A. Breidenassel 45th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 24. – 27.07.2023, Sydney, Australia show abstractWe obtain and compare the non-pulsating part of reflective Photoplethysmogram (PPG) measurements in a porcine skin phantom and a wearable device prototype with Monte Carlo simulations and analyse the received signal. In particular, we investigate typical PPG wavelengths at 520, 637 and 940 nm and source-detector distances between 1.5 and 8.0 mm. We detail the phantom’s optical parameters, the wearable device design, and the simulation setup. Monte Carlo simulations were using layer-based and voxel-based structures. Pattern of the detected photon weights showed comparable trends. PPG signal, differential pathlength factor (DPF), mean maximum penetration depth, and signal level showed dependencies on the source-detector distance d for all wavelengths.We demonstrate the signal dependence of emitter and detection angles, which is of interest for the development of wearables. |

Image-based Live Tracking and Registration for AR-Guided Liver Surgery Using Hololens2: A Phantom StudyS. Khajarian, S. Remmle, O. Amft IEEE EMBS International Conference on Biomedical and Health Informatics (BHI), 15. – 18.10.2023, Pittsburgh, USA Electronic ISSN: 2641-3604, doi: 10.1109/BHI58575.2023.10313488 show abstractWe investigate AR-based tracking and registration of the liver surface for potential surgical applications. Our approach consists of streaming RGBD data from a Hololens2 device, RGBD segmentation using a deep learning model and registering the acquired partial liver surface point cloud with the corresponding virtual liver model. We aim to derive basic requirements for AR-guided liver surgery, thus consider several test cases of partially occluded liver as it would appear in surgical scenarios. To evaluate our approach, we use a 3D-printed phantom with basic texture and rigid structure. Our results show that the visible liver section has a substantial impact of feature extraction and matching, thus the registration process. Test cases, where specific anatomical features are visible, e.g. the right liver lobe, yielded superior outcomes compared to other cases, e.g. only the left liver lobe visible. Moreover, our results showed that large scale Hololens movements during the tracking process affected the registration performance. Our implementation achieved 2-3 frames per second for tracking and registration. We discuss the potential and limitations of utilizing Hololens2 for real-time tracking and registration of the liver surface. To our knowledge this is the first experimental approach for real-time markerless tracking and registration for AR-guided surgery guidance using the Hololens2 sensors only.

Pandemic Preparedness With Pervasive ComputingO. Amft, H. Ghasemzadeh IEEE Pervasive Computing, 22, 4, ISSN: 1558-2590, doi: 10.1109/MPRV.2023.3329556 show abstractThe COVID-19 pandemic has stimulated pervasive computing research and development resulting in new, impactful public health tools, including digital contact tracing, crowd dynamics analysis, and symptom tracking, which are broadly recognized by the public and expert groups alike. In the post-COVID age, focus has shifted to establish a level of pandemic preparedness. Across all preparedness measures, there is the need for interoperable data, pervasive computing tools, and data analysis methods. Considering the open technical challenges, further pervasive computing research is a key to fill the opportunity created over the last years and eventually save more lives at global scale. In this special issue, we capture new technical approaches to the pervasive tool inventory that help dealing with a pandemic situation, but also investigations that highlight opportunities for further research. We aim to motivate continued research and discussion of new ideas on pervasive computing for public health tools that spurs pandemic preparedness.
