The parameters of heart rate variability and blood pressure variability have proved to be useful analytical tools in cardiovascular physics and medicine. Model-based analysis of these variabilities additionally leads to new prognostic information about mechanisms behind regulations in the cardiovascular system. In this paper, we analyze the complex(More)
OBJECTIVE To test whether basic skills acquired on a virtual endoscopic surgery simulator are transferable from virtual reality to physical reality in a comparable training setting. SUMMARY BACKGROUND DATA For surgical training in laparoscopic surgery, new training methods have to be developed that allow surgeons to first practice in a simulated setting(More)
This article presents the approaches taken to integrate a novel anthropomorphic robot hand into a humanoid robot. The requisites enabling such a robot hand to use everyday objects in an environment built for humans are presented. Starting from a design that resembles the human hand regarding size and movability of the mechatronical system , a low-level(More)
PURPOSE Consumers want new prosthetic hand designs that have increased functionality, better cosmetic appearance, and lower weight. METHODS New lightweight hands that fulfill these demands can be designed by integrating a hydraulic system with small fluidic actuators at the digit joints. RESULTS Two different designs of lightweight experimental(More)
This paper proposes a new tracking algorithm within a 3D-SLAM framework that takes segmented range images as observations. The framework has two layers: the local layer tracks the view path and correspondences across the image sequence, using ambiguous landmark surfaces, and provides multiple hypotheses. The global layer conjectures and closes loops. We(More)
In this paper the design, construction, technical characteristics, functionality and control scheme of a new modular hand-arm robot system are presented. This system is designed for applications in robotic and rehabilitation medicine. The development of novel, compact modules is based on flexible fluidic actuators which are equipped with measurement and(More)
PURPOSE To overcome the anterior corneal mosaic (ACM) phenomenon in in vivo confocal laser scanning microscopy (CLSM) and to reconstruct undistorted images of the subbasal nerve plexus (SNP), facilitating morphometric analysis in the presence of ACM ridges. METHODS CLSM was performed in five healthy volunteers. An original image processing algorithm based(More)
