A method for providing haptic feedback is provided for a device that produces haptic noise, such as a power tool with an electric motor that produces noises and vibrations while in operation. An environmental condition of the device can be sensed while the device is being operated and generating haptic noise. A haptic noise characteristic of the device can be determined. A haptic drive signal based on the environmental condition and haptic noise characteristic can be generated. The haptic drive signal can be applied to a haptic output device associated with the device.

Various embodiments of power tool and method of operating same are described. The power tool may include a first position sensor, a second position sensor, a third position sensor, and a controller. The first, second, and third position sensors may each generate a signal indicative of a distance between the respective position sensor and a workpiece. The controller may determine one or more angles of the power tool with respect to the workpiece based on the first, second, and third signal and present an indication as to whether the one or more angles are within a predetermined range. The controller may further obtain a depth measurement based on the first signal, the second signal, and the third signal and generate, based on the obtained depth measurement, one or more control signals that control operation of the power tool.

A device for assisting an operator of a boring instrument having a penetrating element for penetration a work surface that includes a retention member adapted to be connected to a rotating element of the boring instrument and adapted to receive a laser and a plurality of mirrors including a beam splitting alignment mirrors that directs a laser beam in a direction parallel with a penetrating element and perpendicular to a work surface, and a depth indication mirror that reflects a light beam at an angle of less than 90 degrees from said retaining member to a location on said work surface wherein the location of the beams from the alignment beams is maintained at a fixed radial position when the retention member perpendicularly moves towards a work surface and wherein the beam is rotated defines a circle.
