  • Patent number: 7170076
    Abstract: A tool operates with a guide system to identify the orientation of a tool on a work piece. In one implementation, the tool identifies its orientation with respect to a guide signal supplied by the guide system. In an alternate embodiment, the tool determines its absolute orientation, such as a (x, y) coordinate. The tool includes an action component adapted to alter the work piece, such as a cutting head in a router. A guide detector in the tool detects a position of a guide signal from the guide system. A location detector in the tool receives the position data and employs it to determine the tool's orientation. Based on the detected orientation, the tool decides whether any tool adjustments are necessary. Examples of tool adjustments include the following: adjusting the position of the action component, enabling or disabling the action component, and providing operating indicators to direct a tool operator's use of the tool.

  • Patent number: 6878954
    Abstract: A tool is employed in conjunction with alignment, depth, and level detectors. The tool can use all or some of these detectors. The alignment detector provides an orthogonal laser line grid on an incident surface when the detector has a predefined relationship with the surface. The depth detector emits two sets of parallel laser planes that converge with each other. When the laser planes impact on an incident surface two sets of lines are formed. The laser lines from one laser plane set move closer to the lines from the other laser plane set as the depth detector moves closer to the surface—showing changes in depth or distance. The level detector employs two converging laser planes. An operator positions the level detector above an incident surface, so the laser planes' line of intersection appears on the surface if the surface is level. If the surface is not level, lines separate from each laser plane appear on the surface—signaling the need for a level adjustment.

  • Publication number: 20040085646
    Abstract: A multi-beam tool is disclosed which can perform square, plumb, and level function which may be required in a construction environment. The tool can generate in a preferred embodiment up to five orthogonal beams with two beams being plumb and three beams being leveled. Combinations of two level beams, or a level and a plumb beam in orthogonal arrangement can produce a square alignment set of beams. The tool includes in a preferred arrangement a self-leveling pendulum to which a laser and quad-mirror arrangement is secured. The self-leveling pendulum is dampened in order to allow the tool to settle down and provide alignment after the tool is positioned as desired.

  • Patent number: 5134780
    Abstract: An inclinometer 20 includes a module 22 which is mounted to a rail 32. The rail 32 has a hollow I-shaped cross-section which affords substantial resistance to torsional and bending loads about the longitudinal axis 34 of the inclinometer 20. The rail 32 and in particular a first end 36 of the I-shaped cross-section includes first and second curves 48, 50 which define lobes which provide a rail design more suitable for gripping and placement by the user.

  • Patent number: 4912662
    Abstract: An inclinometer 20 has a sensing unit 40 for providing a varying capacitance signal depending on the orientation of the inclinometer 20. An oscillator circuit unit 82 includes the sensor unit 40 as a capacitive element for providing a signal having a period and a frequency depending on the capacitance of the sensor unit 40. A unit 92 is provided for determining the period of the signal. A look-up table unit 96 stores a predetermined relationship between the period of the signal and the angle of orientation of the inclinometer 20. A comparison unit 94 then compares the period of the signal to the period stored in the look-up table unit 96 and selects the corresponding angle which is the angle of orientation of the inclinometer 20. The angle is then displayed on the inclinometer display 25.
