Abstract: A lighting device for displaying liquid globules that float and change shapes within a liquid. The device has a base that supports a globe that contains a liquid. A second inner tube is supported in the globe and contains a second liquid and globules that when heated float and change shapes within the second inner tube. The globe may optionally have globules or other materials disbursed in the globe. Similarly the inner tube may have colorant or other matter disbursed in the second liquid. A light source provides the light and heat to make the device operational.

Abstract: A reversible inflation system allowing a single pump to be used both for inflation and deflation of the air bladder. This embodiment of the inflation system includes a pump with an inlet and an outlet ports and a pump housing having two filling and venting valves. The pump is movably mounted in the pump housing so that the pump can move axially between two locations in the pump housing. In one of the locations, the pump ports align with the housing valves to create an air path that inflates the bladder. In the other location, the pump ports align with the housing valves to create an air path that deflates the bladder.

Abstract: An inflatable mattress topper including an inflatable chamber which may be formed out of polyvinyl chloride with or without lamination or flocking. The inflatable chamber is designed to rest upon a support system, namely a bed without additional securing devices or may be integrated within a conventional mattress. The inflatable chamber being inflated by air to an adjustable level to provide the desired support for its user through plastic tubing connected between a pump and an air inlet sealed to the polyvinyl chloride chamber. The inflatable mattress topper is easily set-up for continual use or removed for occasional use.
