Dynamic Roentgen stereophotogrammetry Dynamic Roentgen stereophotogrammetry Dynamic Roentgen stereophotogrammetry (also referred to as dynamic RSA) is a modern and sophisticated x-ray recording method, used to measure real-time 3D motions of prostheses and bones during motion with high accuracy. It is mostly used in orthopedic research settings and is an advancement of conventional RSA. Conventional static RSA is used to evaluate migration of prosthesis with respect to the bone in three dimensions as a function of time. Migration of the prosthesis are normal 12‐24 months after the surgery. Ongoing migration increase the risk of aseptic loosening with revision surgery as a consequence. The method

No More Woof is a device aiming to translate dogs thoughts into human language using electroencephalography sensoring. An experimental hockey puck inspired by the forms of the Finnish architect Alvar Aalto , researching what happens if the hockey puck isn't round. It's designed with the goal to maximize randomness and have been tested by hockey teams as Swedish Hammarby IF. A small prototype that can lift small animals (2.4 kg) a few centimetres (up
