A while ago (around 2 or so years) I did quite a bit of mechatronics and Kalman Filters were used resonable effectively for data fusion in IMUs. I wouldn't be surprised if there were better methods around but all the standard chipsets used them at that time. EDIT: I forgot but I've seen them used more recently by CERN for particle trajectory prediction as part of their hit tracking system. I only know this since they wrote about it in some of their supporting documentation for their latest kaggle comp [0].
