Title:
AN IMPROVED ROTARY SIGNAL COUPLER
Document Type and Number:
WIPO Patent Application WO2001086749
Kind Code:
A3
Abstract:
The present invention relates to a rotary signal coupler, that is to say a device for providing signal coupling between two components which are rotatable relative to each other. A coupler is provided comprising a first substantially circular track secured to a first support (not shown) and a second substantially circular track (102) secured to a second support (10) which is rotatable relative to the first support. The first and second tracks are coaxial with the axis of rotation of the rotatable second support (10) and are adjacent each other so as to provide signal coupling therebetween. The second track (102) has at least two gaps (106, 108) therein which form electrical discontinuities between separated track portions. The separated track portions are electrically connected (110) to one another. Signal coupling with a rotatable support having a relatively large diameter may be thereby improved.
