Abstract
A method for use in connection with installing a cable into a conduit having a first conduit end and a second conduit end, comprising the steps of—providing the cable with a metallic attribute,—providing within or proximate to the conduit, sensing means for sensing the metallic attribute,—introducing the cable into the first conduit end and driving it towards the second conduit end and—detecting that the sensing means has sensed the metallic attribute by sensing a change in inductance levels of the sensing means.
Claims31
A method for use in connection with installing a cable into a conduit having a first conduit end and a second conduit end, comprising the steps of
- providing the cable with a metallic attribute,
- providing within or proximate to the conduit, sensing means for sensing the metallic attribute,
- introducing the cable into the first conduit end and driving it towards the second conduit end, and
- detecting that the sensing means has sensed the metallic attribute by sensing a change in inductance levels of the sensing means.
A device for use in connection with installing a cable provided with a metallic attribute, into a conduit having a first conduit end and a second conduit end, comprising sensing means for sensing the metallic attribute, and detecting means to detect that the sensing means has sensed the metallic attribute by sensing a change in inductance levels of the sensing means.
A device for use in connection with installing a cable into a conduit having a first conduit end and a second conduit end, the cable including sensing means for sensing a metallic attribute, comprising
- a metallic actuator, and
- detecting means to detect that the metallic actuator has been sensed by the sensing means by detection of a change in the inductance levels of the sensing means.
