Abstract: A drum dampening device includes a foam pad adapted to be selectively engageable with drum wires on the drum. The foam pad is configured to dampen vibrations of the drum wires when the foam pad is engaged with the drum wires. A support plate is coupled to the foam pad, and a base plate is coupled to the support plate. An adjustment lever is coupled to the support plate and the base plate. The adjustment lever is selectively transitional between a first position and a second position, with transition of the adjustment lever from the first position toward the second position causing at least a portion of the support plate to move away from the base plate resulting in engagement of the foam pad with the drum wires.

Abstract: A case for a mobile device includes a bumper portion and a module portion. The module portion is attached to the bumper portion. The bumper portion has a border configured to receive a mobile device. The module portion includes a base portion, a back plate and battery portion. The base portion is attached to the back plate. The battery portion is positioned between the base portion and the back plate. The battery portion includes a plurality of battery cells, a printed circuit board assembly and a plurality of electromagnetic induction coils all operably connected to one another.
