2. Certain claims were found unsearchable
3. Unity of invention is lacking
4. Title of the invention
The text is approved as submitted by the applicant.
The text has been established by this Authority to read as follows:
METHOD AND SENSOR FOR ROTATION MEASUREMENT OF AN ELONGATED OBJECT

5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

The present invention relates to a sensor for contactless measurement of local rotation on an elongated object, preferably a yarn, the sensor being composed of a first circular pattern (A) of electrodes around the longitudinal axis of the object and a second circular pattern (B) of grouding electrodes arranged around the longitudinal axis of the object, where the second pattern is interdigitated with the first pattern such that the grounding electrons function as a screen between any two consecutive electrodes of the first pattern and further a method therefor, as well as improved methods and systems for twisting yarns based on the data obtained from this sensor and the aforementioned methods.


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     1    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
