Abstract: A position detector for generating 3D position information of an object in a position determination space for the object. The position detector has a camera with a lens and an image sensor that defines an imaging area with one first light deflecting element arranged in the imaging area as the camera and the at least one light deflecting element are adapted to simultaneously produce on the image sensor at least two images of the position determination space, a first image being produced by light beams deflected at the first light deflecting element, the at least two images differ with respect to the viewing direction of the position determination space.

Abstract: The present invention relates to a process for preparing copolymers of tetrafluoroethylene with ethylene, and optionally with a third monomer, of vinylic character.The process is characterized in that tetrafluoroethylene is caused to react with ethylene and with the optional third, vinylic, monomer in an aqueous emulsion with the aid of a polymerization initiator of peroxy type, at a temperature within the range between 30.degree. and 95.degree. C. and under a pressure within the range of from 1.5 to 4.0 MPa, in the presence of tert.-butyl alcohol and of 1,1,2,2-tetrachloro-1,2-difluoroethane.

Abstract: A process for preparing vinylidene fluoride homopolymers having low molecular weight and its copolymers by carrying out the polymerization in the presence of a radical initiator at a temperature ranging from 20.degree. to 160.degree. C. in a solvent of general formula R--COO--R.sub.1, wherein R is hydrogen or an alkyl radical having up to 4 carbon atoms and R.sub.1 is an alkyl radical with up to 5 carbon atoms.
