Abstract: An adjustable mounting assembly for a table saw fence includes an elongate track for connecting to a table saw. A carriage is supported by and movable longitudinally on the track for carrying the fence such that the fence extends across a tabletop of the table saw. An incremental adjustment wheel mechanism is rotatably supported by the carriage and interengages the track. The adjustment wheel mechanism is rotated a selected amount to adjust the position of the carriage on the track. The track carries an electronic sensor strip and a digital readout attached to the carriage movably cooperates with the electronic sensor strip for measuring and displaying the longitudinal position of the carriage on the track and the position of the fence relative to the saw blade.

Abstract: A drill press laser alignment device includes a rigid plate that is attachable to the column of the drill press above the table. A plurality of cylindrical support posts carried by the plate engage the column to fixedly orient the plate relative to the table. A pair of laser modules mounted rotatably to the plate produce respective planar laser beams that are projected perpendicularly against the table such that the beam appears as a laser line on the table. The laser modules are manipulated to produce a laser crosshair alignment marking wherein the projected laser lines intersect at a point operatively aligned with the axis of the drill bit. This forms a target for accurately positioning a workpiece to be drilled on the table below the drill bit.

Abstract: A digital protractor is provided for measuring spring and wall angles and determining and effecting bevel and miter angle adjustments of a miter saw to adjoining pieces of trim in accordance with the measured spring and wall angles. The protractor includes a pair of pivotally interconnected arms. At least one sensor is attached to one of the arms and a digital readout is secured to the other arm. The readout includes means for determining the bevel and miter angles such that the protractor can be set to those angles to properly adjust the miter saw in accordance with the calculated angles.

Abstract: A two plane protractor for installing adjoining pieces of molding and trim includes a first pair of wall angle measurement arms interconnected to one another through a gear assembly that allows the wall angle measurement arms to be angularly adjusted in unison relative to one another in a first degree of freedom. A pair of spring angle measurement arms are attached respectively to the wall angle measurement arms for rotating in a second degree of freedom about respective longitudinal axes of the wall angle measurement arms. A first sensor measures angular displacement between the first and second wall angle measurement arms and a second sensor measures rotational tilt of at least one spring angle measurement arm. A microprocessor calculates bevel and miter angles based upon the measured wall and spring angles.

Abstract: A digital angle gauge includes a gauge body having a reference surface that is engageable with an object to be measured for angular inclination. An angle sensor and processor mounted in the body determine an inclination angle of the object with which the reference surface of the gauge body is engaged. A digital screen is pivotally mounted to the gauge body for visually displaying the determined inclination in both incremental and absolute angles that are displayed simultaneously and side by side.

Abstract: A digital protractor for measuring angular displacement from a referenced surface includes a substantially congruent pair of pivotally interconnected upper and lower arms, which arms are superposable upon one another. Each arm has a pair of substantially parallel engagement edges extending longitudinally of the arm. One of the arms is engagable along an engagement edge thereof with the reference surface. A capacitive sensor is secured to the lower arm and a digital readout device is secured to the upper arm for operatively cooperating with the capacitive sensor to measure and display the angular displacement from the arm engaging the reference surface to the other arm.
