The invention provides a method for demounting a cable tensioned between a first and second anchorage points on a structure. The method comprises the following steps: slackening the cable so that a running part of the cable is freed from one of said first and second anchorage points; freeing said running part of the cable from the other said first and second anchorage points; supporting said running part of the cable; and removing said running part of the cable away from at least one of said first and second anchorage points.

Method for demounting a tensioned cable, a system and associated devices

A magnetoresistive sensor including: a first pinned-magnetization magnetic layer and a free-magnetization magnetic layer, separated by first separating layer for magnetic uncoupling. The sensor further includes a second pinned-magnetization magnetic layer, separated from the free-magnetization magnetic layer by a second separating layer for magnetic uncoupling, the first and second separating layers being located on either side of the free-magnetization magnetic layer, and the respective magnetizations of the first pinned-magnetization magnetic layer and of the free-magnetization magnetic layer, in the absence of an external field, are substantially orthogonal. The orientation of the magnetization of the second pinned layer is selectable.
