Signal coupling system
First Claim
Patent Images
1. A signal coupling system for the transfer of data and/or power signals, the system comprising:
- a first transceiver having a primary loop arranged at a first end thereof with a first plane enclosed by said primary loop being arranged substantially orthogonal to said first end;
a second transceiver having a secondary loop arranged at a second end thereof with a second plane enclosed by said secondary loop being arranged substantially orthogonal to said second end;
said transceivers arranged oppositely with said first and said second ends overlapping such that said first plane and said second plane are in substantially parallel alignment to facilitate electromagnetic coupling therebetween.

Abstract
A signal coupling system for data and/or power signalling in a confined space such as in tubing within a hydrocarbon extraction well. First and second transceivers are arranged with primary and secondary loops lying orthogonal to the ends of the transceivers. The transceivers can be narrower for access to confined spaces. Each loop is housed in a semi-cylindrical housing with a planar face, so providing a cylindrical body when oppositely arranged for the transfer of electromagnetic radiation therebetween. Guiding surfaces are also provided on the housing to assist in bring the coupling system together in the confined space.

9. A method of data and/or power transfer, comprising the steps:
-
(a) providing a signal coupling system having; a first transceiver having a primary loop arranged at a first end thereof with a first plane enclosed by said primary loop being arranged substantially orthogonal to said first end; a second transceiver having a secondary loop arranged at a second end thereof with a second plane enclosed by said secondary loop being arranged substantially orthogonal to said second end; (b) connecting said first transceiver to a device; (c) bringing said second transceiver to said first transceiver; (d) overlapping said ends of said transceivers such that said first plane and said second plane are in substantially parallel alignment to facilitate electromagnetic coupling therebetween; and (e) transmitting data and/or power between said transceivers by electromagnetic induction. - View Dependent Claims (10)
