Utility
Inductive position detector
28 Dec 20
An inductive detector is provided for measuring the relative position of bodies along a measurement path comprising: an inductive target arranged along the measurement path; a laminar antenna arranged facing a portion of the target; an electronics circuit arranged along the measurement path; wherein, the inductance of at least one winding in the antenna varies continuously in proportion to the relative position of target and antenna.

Utility
Optical rotation angle measuring system
27 Apr 20
The present invention is directed to an optical system for measuring the rotation angle of rotatable object having a rotation shaft (2), which system comprises a reflective diffraction element (6) mounted on said shaft and a module that includes a radiation source (8) emitting a monochromatic beam (bo) towards this element and a radiation-sensitive detection structure (14, 16), the diffraction element is configured to project diffraction order images (18) of its pattern onto associated sections (50(1)-54(2)) of an annular grating structure forming part of the detection structure and the surface size of the diffraction element is smaller than 20% of the surface size of the annular grating structure.
