Accurate positioning using Short-Range Communications
2009 International Conference on Ultra Modern Telecommunications & Workshops, 2009Satellite-based positioning systems such as GPS have been used for positioning by the transportation industry for decades. Accurate positioning (≪1 cm error) requires the availability of multiple (5+) GPS signals which is ‘possible’ only in suburban communities but utterly unachievable in urban areas.

Situation-aware choice of the most accurate positioning system
2012 IEEE International Conference on Pervasive Computing and Communications Workshops, 2012With the increasing proliferation of powerful mobile devices, the use of location-based services has gained noticeable momentum. However, new challenges arose with the higher user mobility. Especially in the context of location-based services, one of these challenges is the problem of selecting the most suitable positioning technology. This paper gives

Accurately positioning a duplicate cast on the surveying table
The Journal of Prosthetic Dentistry, 1989The path of insertion must be registered in such a way that it can be easily transmitted to the dental technician who then should also be able to transfer the original information from the master cast directly to any necessary duplicate casts. A system is presented that fulfills these requirements by means of simple tridimensional markings on the ...
