摘要 |
<p>The invention is related to an arrangement for detecting a mechanical contact between two objects moving in respect each other. The arrangement includes one or several transmission line (PSTL) to transfer electrical, acoustical or mechanical energy and a contact of said objects in that area, where said transmission line (PSTL) is, cause a change in properties of energy transfer of said transmission line (PSTL) and this change is detected by the means of the arrangement (RECEIVER, PROCESSOR) either as a reflection of energy or as a change of energy transmission capability or as both.</p> |
