Blade-height optimization indicator for a table saw

A blade-height optimization indicator attachable to a table saw having a table surface, a fork, a blade protruding through the table surface to with a configurable height, a riving knife that is fixed relative to the blade, and one or more blade guards each of which at a first end is rotatably mounted to the riving knife, thus forming an axis of rotation of the blade guard, and at a second end is displaceable upwards as a workpiece to be cut on the saw is urged along the table surface towards the blade thereby rotating the blade guard around the axis of rotation, the optimization indicator comprising:

• a first angle sensor adapted to output a first angle sensor signal indicative of the angular position about the axis of rotation of a first one of the blade guards of the table saw;
• a controller adapted to receive the first angle sensor signal and output a first indicator control signal, wherein the first indicator control signal indicates based on the first angle sensor signal whether the height of the blade is optimized relative to a thickness of a workpiece;
• and
• a display adapted to receive the first indicator control signal and visually indicate based on the first indicator control signal whether the height of the blade is optimized.
