Updates to the DebriSat Project in Support of Improving Breakup Models and Orbital Debris Risk Assessments Open
Existing DOD and NASA satellite breakup models are based on a key laboratory test, the 1992 Satellite Orbital debris Characterization Impact Test (SOCIT), which has supported many applications and matched on-orbit events involving older sa…

Haptic model of milling a virtual petrosal bone Open
For the milling simulation at the petrosal bone, realistic haptic VR interaction between CT bone-data and burr is required. Known linear models can calculate the abrasion but do not represent the reality. We present a new exponential model…

3D haptic training system for micorsurgery of the ear – BMBF-Haptivist Open
In the history of ENT, the instruments for performing a mastoidectomy have changed (including a drill instead of a chisel). However, even 145 years after the initial description (Schwarzte & Eysell), the surgical steps and the risk structu…
