Abstract: A device capable of providing tactile and audible stimulation comprised of multiple shells of flexible material embedded into the surface of a housing body where the internal volume under each shell is connected via internal passages within the housing body to corresponding volumes under neighboring shells. This device is configured in such a fashion that when one or more shells are transitioned from a convex state to a concave state an equal number of shells previously in concave state are restored to convex state. This produces the tactile sensation that the user is popping a bubble along with a corresponding popping sound. The user can repeatedly depress shells in a way that does not change the total number of convex shells in the device and therefore it may be operated indefinitely without reconfiguration or reorientation.

Abstract: A device for effectively controlling and collecting debris created when cutting or trimming a material. This device includes a hollow generally prismatic and rigid transparent body, an evacuation penetration in the body for the removal of debris, an interface opening in the body where the device is intended to contact a cutting substrate, a tool access penetration in the body where the blade of a cutting tool, such as a jab saw, can be inserted through the body and into the cutting substrate as well as edge protection around the tool access penetration to prevent damage to the device body if contact with the cutting tool is made when in operation. Debris created during the operation of the cutting tool is contained within the device body and evacuated via vacuum through the evacuation penetration.
