Publication number: 20100219823Abstract: A coil arrangement for a magnetic sensor for detecting metallic objects in a subgrade, in particular structures made of concrete, brick, and wood, as well as a method for energizing and reading out this coil arrangement, is disclosed. The coil arrangement includes one or preferably two stacked outer main coils via which a perpendicular magnetomotive force of the subgrade is effected. Provided within the outer main coil(s) is, on the one hand, a quartet of a total of two pairs of parallel coils lying symmetrical to the axis of the main coil(s), via which a magnetomotive force penetration of the subgrade in two directions parallel to the subgrade surface is possible.

Publication number: 20100186504Abstract: A method for the detection of objects embedded in building structure subgrades such as cable, concrete reinforcing bars, conduit pipe and the like as well as a hand-operated sensor with an adaptive detection threshold operating according to the method, is disclosed. To reduce an over-detection with the adaptation of the detection threshold, a change in the direction of movement of the sensor being guided over the surface area is recorded with respect to an embedded object. The determination of a change in the direction of movement preferably takes place by measuring the sensor acceleration in two directions with respect to the embedded object. Corresponding speeds are computed at least as estimates from the acceleration values in order to generate a conclusion about a reversal of the direction of movement.Type: ApplicationFiled: November 20, 2009Publication date: July 29, 2010Applicant: Hilti AktiengesellschaftInventors: Patrik Cipriano, Torsten Gogolla, Andreas John, Christoph Wuersch
