Title:
DETECTION OF REVOLUTIONS OF A TYRE AND WHEEL ASSEMBLY BY MEANS OF THE EARTH MAGNETIC FIELD
Document Type and Number:
WIPO Patent Application WO2004110793
Kind Code:
A3
Abstract:
The invention relates to stand-alone device mounted on a tyre (14) and wheel assembly for detecting the revolutions thereof comprising at least one signal emitting sensor (10) and an interpretative device connected thereto for interpreting the signals emitted thereby. Said sensor is embodied in the form of a passive transducer (10) whose signals are proportional to temporal variations of a magnetic flux which passes through said sensor and is rotationally connected to the tyre (14) in such a way that the revolutions of said assembly correspond to the sensor revolutions. An assembly (14) provided with the inventive stand-alone device and a method for detecting the revolutions thereof are also disclosed.
