Patent attributes
The present invention is directed to a cushioning device. The present cushioning device has many attributes that are common with many cushions. Some of these common attributes are at least one bladder having a top surface, a bottom surface and at least one side surface positioned between the top and the bottom surfaces. Another common attribute is a bladder cavity being defined by the top surface, the bottom surface and the at least one side surface. The present invention differs from other bladders in that there is a first conductive material and a second conductive material are positioned within the bladder cavity, positioned away from the bottom surface of the bladder, and capable of acting like a switch for a reactive device. The reactive device is electrically interconnected with the first and second conductive materials. When the first and second conductive materials contact each other the reactive device is capable of responding by sounding an alarm and/or re-inflating the bladder cavity with a fluid.
