Abstract: A plurality of modules are arranged on the broadside of a ship, each module includes a housing, and the housing is provided with a composite gas supply assembly, a composite airbag assembly, an intelligent control assembly, and a mechanical transmission assembly; the intelligent control assembly is configured for predicting the impact energy and a collision angle of a collision object, sending an inflation instruction to the composite gas supply assembly, inflating a large airbag to a proper air pressure, inflating a small airbag to a rated air pressure, and sending an angle adjustment instruction to the mechanical transmission assembly to adjust the collision angle of the small airbag; the large airbag is matched with the small airbag to fully absorb a collision force vertically acting on the surface of a hull.

Abstract: The present invention relates to an external counter pulsation apparatus that provides an improved treatment results while having a reduced energy consumption, noise, and/or heat during operation and/or an increased mobility. The counter pulsation apparatus can have a pump member for producing a fluid medium and a valve member for selectively allowing the fluid medium to inflate and deflate a fluid pouch adapted to be mounted onto a body portion of the patient. A control device can be provided to control the inflation and deflation of the valve member in accordance with a physical signal of a patient. An output variation device can be provided to vary the fluid medium output from the pump member to maintain the fluid medium pressure at a predetermined value. Additionally or alternatively, one or more of the pump member, the valve member, the control device, and the output variation device can be movable to the patient's location to carry out the counter pulsation treatment.
