A self-control heating and cooling water mattress comprises a temperature control system which consists of liquid filling pads, a heat exchanger, a throttling device, a compressor and a controller. An upper liquid filling mattress and a lower liquid filling mattress are arranged in a mattress frame and are both filled with water or other liquid; and an insulation layer is arranged between the upper liquid filling mattress and the lower liquid filling mattress; an upper heat exchanger is arranged inside the upper liquid filling mattress and a lower heat exchanger is arranged inside the lower liquid filling mattress. When the upper liquid filling mattress is used as a cool mattress, the upper heat exchanger functions to be an evaporator and the lower heat exchanger as a condenser; the heat from human body is then absorbed by the upper liquid filling mattress and dissipated through the lower liquid filling mattress. If the upper liquid filling mattress is used as a warm mattress, the upper heat exchanger is changed into the condenser and the lower heat exchanger into the evaporator; the heat in the lower liquid filling mattress is absorbed by the lower heat exchanger and dissipated through the upper heat exchanger. People then feel warm by absorbing the heat from the upper liquid filling mattress.

The Garden Waterbed is constructed of a durable tube of flexible UV protected material. The ends of the tube have been sealed, enabling it to hold water. Circular holes have been cut out and sealed down the center length of the tube, at regular intervals. A valve is installed at one end of the tube, allowing water to be filled into the large single chamber and hold it with a tight seal. There are multiple purposes of the Garden Waterbed. The water bed's intended use is; to be rolled out in a agriculture environment or garden area, to be filled with water, and to have plants buried in the soil within the growth units. The surrounding water increases the thermal mass surrounding the plants in the circular holes. The thermal mass absorbs the suns energy and increases soil temperature, thus increasing the growing season and boosting production. The opaque plastic stops sunlight from reaching the ground and eliminates weeds and undesirables from competing with your crop. At the same time insulating the ground and shading the soil, decreasing crop water consumption and increasing earthworm populations, increasing overall cleanliness of the subject grown, and increasing disease and insect infestation protection. The flexible design allows for quick and easy installation and roll away storage.

A medium-small ship water cushion anti-sinking system belongs to the technical field of ship ocean engineering.
