Abstract: A flexible debris shield for handheld power drills for collecting debris generated while cutting or drilling holes in a work surface. The debris shield is made from a transparent flexible material in a way that it allows the debris receptacle to fold and envelop an uneven surface or in cases where the intended workspace area's width is narrower than the diameter of the shield.

Abstract: A sensor, comprised of various mechanical components and electromechanical components, that measures/detects the relative position between two (2) or more objects and can measure/detect relative acceleration of one (1) or more objects, using fundamental natural physical forces, e.g. magnetism, electrostatics. More particularly, this invention relates to a sensor that can measure/detect the relative position of two or more objects and/or measure/detect the acceleration of one or more objects. Specifically, this invention uses fundamental physical forces in combination with mechanical components to actuate electro-optical-mechanical signal devices, e.g. electrical switches, optical switches, magnetic switches.
