The device has a small volume, a simple structure, and a low cost.

This apparatus is simple, highly effective and energy and cost efficient.

The catalysts have inexpensive components, and are inexpensive to produce.

Space and cost-saving cascaded parallel connections are possible.

The increase in resolution is achieved by a few additional and economic components.

The inventive rotary piston engine has a small volume, runs at high speed, and is inexpensive and operationally safe to produce.

The device provides adequate signal to noise ratio with minimum sophisticated or expensive components.

The process is easy to control, has low energy consumption, and is inexpensive.

This structure, particularly when made from plastics material, is low in complexity and cost and lightweight.

The circuit has a simple structure, needs few components, and has a low cost; and moreover, achieves an obvious effect without being affected by the data frequency.

Using this inventive principle, it is possible to create a particularly simple, lightweight, cost-effective and compact wheel suspension which, while comprising only a few components, has very good road characteristics.
