  • Publication number: 20110131820
    Abstract: The invention relates to a hand-held jigsaw, especially a compass saw, having a housing and a lifting rod with a pendulum mechanism, especially a pendulum lever, with which a pendulum stroke can be given during sawing to a saw blade carried by the lifting rod, especially a jigsaw blade. According to the invention, the hand-held jigsaw can be used more safely and in more special applications as the lifting rod is arranged such that it can rotate about the axis thereof and pivot transversely to the axis, and the pendulum mechanism can rotate about the axis.

  • Patent number: 7956794
    Abstract: A radar device is described, in particular a hand-held short-range radar for determining the location of objects enclosed in a medium, including at least one radar sensor, which generates a first, high-frequency detection signal for penetrating a medium to be tested in such a way that information about an object enclosed in the medium can be obtained by measuring and analyzing the reflected detection signal of the radar sensor. At least one additional sensor is provided for generating at least one additional, second detection signal for obtaining information about the object enclosed in the medium. The method on which this radar instrument is based is also described.
