A trampoline having a frame, a bounce member and a bounce sensor, sensing bounces activates lights and provide sounds for entertainment and training purposes. A control box interprets a variety of inputs from the bounce sensors and outputs a variety of lights and sounds. A light is activated underneath the bounce member when the bounce sensor senses a bounce. One are more sets of lights can be used. The best mode is a spring post configuration sensor. The lights can be encapsulated within a plastic lamination having an upper clear surface and a lower reflective surface.

A pad like device adapted to be placed over a phototherapy light source contains a medium that provides a comfortable support for a patient during phototherapy treatment and allows a portion of the light emitted by the light source to pass through the pad for phototherapy treatment.

The present invention details a pressurizable mattress. The mattress has at least one inflatable cushion having a pair of sides, and at least one set of an electromagnetic energy emitting device and an electromagnetic energy receiving device. The electromagnetic energy emitting device, when operating, illuminates the interior of the inflatable cushion. The electromagnetic energy receiving device collects the illuminating energy. The operation of the mattress requires a means for measuring the optical aperture of the inflatable cushion. The measuring means determines the optical aperture of the inflatable cushion by measuring the quantity of illuminating energy collected by the electromagnetic energy receiving device when the electromagnetic energy emitting device illuminates the interior of the inflatable cushion.
