| 20100186504 | METHOD AND HAND-OPERATED SENSOR WITH ADAPTIVE DETECTION THRESHOLD FOR THE DETECTION OF FOREIGN OBJECTS EMBEDDED IN BUILDING STRUCTURE SUBGRADES - 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. | 07-29-2010 |
| 20100219823 | OPERATING METHOD AND COIL ARRANGEMENT FOR A MAGNETIC SENSOR FOR DETECTING METALLIC OBJECTS IN A SUBGRADE - 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. To further improve the accuracy and reliability of localizing objects and estimating depth of cover, two pairs of smaller orthogonal coils each opposite from one another and also arranged symmetrically to the axis of the main coil(s) are provided. | 09-02-2010 |
| 20100302527 | LASER INSTRUMENT FOR ELECTRO-OPTICAL DISTANCE MEASUREMENT - A laser instrument for electro-optical measurement of the distance of a target object to a reference mark is disclosed. The instrument includes a housing, a measuring device which emits a laser beam and determines a distance value from the receiving beam coming from the target object, an outlet opening to couple out the laser beam from the housing, a display device to display the distance value and an operating device to operate the laser instrument and to start a distance measurement. The display and operating devices are arranged on an upper side of the housing. The outlet opening is arranged in the upper side, in the lower side opposite from the upper side or in a side surface of the housing. | 12-02-2010 |
| 20100309453 | LASER INSTRUMENT FOR ELECTRO-OPTICAL DISTANCE MEASUREMENT - A laser instrument for electro-optical measurement of the distance of a target object to a reference mark is disclosed. The instrument includes a housing, where the housing has an outlet opening to couple out a laser beam from the laser instrument, a measuring device which emits a laser beam and determines a distance value from the receiving beam coming from the target object, a display device to display the distance value, an operating device to operate the laser instrument and to start the distance measurement, and an optical sighting device to align the laser beam on the target object. The direction in which a user looks into the optical sighting device is aligned parallel to the optical axis of the laser beam coupled out of the laser instrument via the outlet opening. | 12-09-2010 |
