Abstract: Exemplary systems and methods for modifying and enhancing pyrotechnic emissions and effects are provided including systems for irradiating pyrotechnic emissions using electromagnetic radiation sources with programmable electromagnetic radiation profiles. Exemplary systems include coupling an electromagnetic radiation source to a pyrotechnic device to irradiate pyrotechnic emissions or irradiating pyrotechnic emissions with an external electromagnetic radiation source. Exemplary methods include identifying a desired pyrotechnic emission output and designing an emission and effect output to meet the desired output.

Abstract: A circular saw includes a footplate and an upper guard coupled to a saw blade. The footplate has a width between two lateral edges in a direction perpendicular to the saw blade. The upper guard has a radius extending from the axis of the blade to the outermost surface of the upper guard in the radial direction. A DC brushless motor is drivingly coupled to the saw blade and is disposed above the footplate. The motor has a rotational axis within forty five degrees of parallel to the width of the footplate, or within forty five degrees of parallel to the radius of the upper guard. The motor extends towards one of the lateral edges of the footplate in the width direction, or towards the outermost surface of the upper guard in the radial direction.

Abstract: A power tool in one embodiment includes a motor supported by a frame, a foot defining a first plane, a first guide fixedly positioned with respect to the foot and defining a first arc in a second plane, a second guide fixedly positioned with respect to the foot and defining a second arc in a third plane, wherein the second plane and the third plane are orthogonal to the first plane and the first arc and the second arc are offset when projected onto a reference plane parallel to the second plane and the third plane, a first pin fixedly positioned with respect to the motor and guided by the first guide; and a second pin fixedly positioned with respect to the motor and guided by the second guide.
