Inversion table is used as a treatment primarily for back pain. It is designed to utilize gravity and create some traction in the spine and pelvis, which can take pressure of compressed joints, discs and nerves. Inversion therapy usually involves laying at a downward angle, not hanging completely upside down. The effectiveness of using inversion tables for back pain is not well studied, but anecdotal reports suggest that some people do experience at least short-term relief.

A turbocharger, or turbo, is a gas compressor. It is used to force air into an internal combustion engine. A turbocharger is a form of forced induction. It increases the amount of air entering the engine to create more power. A turbocharger has the compressor powered by a turbine. The turbine is driven by the exhaust gas from the engine. It does not use a direct mechanical drive. This helps to improve the performance of the turbocharger. Early builders of turbochargers called them as "turbosuperchargers".

Hydraulic piston parts are disc or short cylinder fittings closely within an engine cylinder in which they move up and down against a liquid or gas, used in an internal combustion engine to derive motion, or in a pump to impart motion. A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders, and pneumatic cylinders, among other similar mechanisms. It is the moving component that is enclosed in a cylinder and made gas-tight by piston rings.

indoor air into a container that separates oxygen from room air and concentrates it to provide oxygen continuously to users.

Oxygen plant is an industrial system designed to generate oxygen. It typically uses air as a feedstock and separate it from other components of air using pressure swing absorption or membrane separation techniques. Such plants are distinct from cryogenic separation plants which separate and capture all the components of air. Oxygen finds broad application in various technological processes and in almost all industry branches.
