  • Subsurface exploratory radar detector for a hand tool device
    Patent number: 6600441
    Abstract: A radar detector for exploration of subsurface embedded objects comprising an antenna array (1) for high-frequency electromagnetic waves, which is connected and individually switchable with at least one transmit/receive unit, a time-controlled signal processor, an evaluation device for SAR and a display device. The antenna array (1) exhibiting at least three antennas (sx, rx, sy, ry) scanning an area by their positioning.
    Type: Grant
    Filed: October 9, 2001
    Date of Patent: July 29, 2003
    Assignee: Hilti Aktiengesellschaft
    Inventors: Stefan Liedtke, Harald Schmitzer, John Ewen, Klaus Dass
  • Positioning aid for a hand tool device
    Patent number: 6587184
    Abstract: A positioning aid (1) for a hand tool device (3) driving tool (2), in a working direction (A), with a distance measuring system (4) mounted thereon. The distance measuring system (4) has at least one distance measuring sensor (5) for measuring the distance from the distance measuring sensor (5) to an object (6), along a line of measurement (M, M′, M″), and a computing unit (7) for comparing the measured value with a pre-selected desired value (S) and for producing a signal dependent on the comparison, wherein the line of measurement (M, M′) is oriented at least partially perpendicular to the working direction (A).
