Recently we challenged the view that arterial desaturation during hypergravity is caused by redistribution of blood flow to dependent lung regions by demonstrating a paradoxical redistribution of blood flow towards non-dependent regions. We have now quantified regional ventilation in 10 healthy supine volunteers at normal and three times normal gravity (1G(More)
Vertical TakeOff and Landing (VTOL) capable Mini Unmanned Aerial Vehicles (MUAV) are an economic alternative to real helicopters if local aerial pictures or other aerial measurements are needed. With electronic stabilization, GPS based position-hold and autonomous way-point functions these systems are easy to operate. While autonomous take off and flying(More)
This paper describes an absolute localisation method for an unmanned ground vehicle (UGV) if GPS is unavailable for the vehicle. The basic idea is to combine an unmanned aerial vehicle (UAV) to the ground vehicle and use it as an external sensor platform to achieve an absolute localisation of the robotic team. Beside the discussion of the rather naive(More)
