  • Frictional pivots for gravitational alignment
    Patent number: 8068221
    Abstract: A frictional pivot 100 for use in a device measuring gravitational alignment is provided. The frictional pivot 100 comprises a gravity-responsive directional means 200 for indicating a datum direction of alignment with gravity; frictional pivoting means 300, 400 for allowing the gravity-responsive means coarsely to align with gravity; vibration means 303, 403 for vibrating one or more elements of the pivoting means; and portable power means 303a for powering the vibration means 303, 403.
    Type: Grant

  • Laser light referencing tool
    Patent number: 6351890
    Abstract: A laser light referencing tool comprises laser means for emitting a visible laser beam, portable power means for powering the laser means, and gravity-responsive directional means for establishing a datum direction for the laser means, the gravity-responsive directional means preferably being batteries contained within a cylindrical housing which is axially attached to another cylindrical housing in such a manner that the relative rotational positions of the two cylindrical housings are controlled by friction.
