Abstract: A multi-chamber inflatable mattress includes a main air chamber, upper and lower peripheral air chambers, and an upper air chamber. The main air chamber includes internal tensioning structures which cooperate with a bottom mattress panel and a lower intermediate panel to provide a generally box-shaped, mattress-sized inflatable structure upon pressurization. A second, upper intermediate panel cooperates with a top mattress panel to define an upper air chamber which defines the sleeping surface. The main air chamber receives pressurized fluid directly from a valve, while the lower and upper peripheral air chambers are in direct fluid communication with the main air chamber but not the valve. The upper air chamber is in direct fluid communication with the upper peripheral air chamber, but not the main chamber or valve.

Abstract: An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

Abstract: A two-in-one copper chloride/copper bromide disinfector and a method of controlling the same. In operation, when copper is released, the positive and negative electrodes of a copper billet are periodically reversed, while the positive and negative electrodes of a titanium plate/graphite polar plate are in an uncharged state. When chlorine/bromine is released, the positive and negative electrodes of a titanium plate/graphite polar plate are periodically reversed, while the positive and negative electrodes of the copper billet are short-connected, then connected to the negative electrode of the titanium plate/graphite polar plate, or applied thereon with an electric voltage that is lower than the electric voltage of the negative electrode of the titanium plate/graphite polar plate. With this method, the copper billet out of operation is shorted-connected to the negative electrode of the titanium plate/graphite polar plate or connected to an electric voltage that is lower than that of the negative electrode.

Abstract: A combination ladder assembly and pool includes a pool having a side wall and a support member positionable along an inner surface of the side wall of the pool. The support member may include at least one aperture. Additionally, the combination ladder assembly and pool further includes a ladder positionable along an outer surface of the side wall of the pool. The ladder may be removably coupled to the support member. The ladder further includes at least one leg having a first end and a second end and a plurality of steps. The plurality of steps may be coupled to the leg of the ladder between the first end and the second end of the leg. The ladder may be moveable between a use position, permitting ingress into the pool, and a storage position. When the ladder is in the use position, the leg of the ladder is supported by the support member. When the ladder is in the storage position, the ladder extends from the aperture of the support member to cantilever from the support member.

Abstract: A technique of integrating advertisements through broadcasting with that through a network out of advertisement media and particularly a technique of producing high advertisement effectiveness by automatically synchronizing advertisement timing is provided.

Abstract: An air-inflated mattress, comprising a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, wherein said shroud band connects the top and bottom layers together to form an inflatable bladder. A middle layer below said top layer is partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, via a plurality of air vents in the middle layer, creating air-pockets arrayed on the top surface of the air mattress.

Abstract: A double air-inflated mattress having an upper chamber and a lower chamber, the upper chamber having a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, the outer shroud band connecting the top and bottom layers to form an inflatable bladder; a middle layer below said top layer partially sealed to the top layer to form a plurality of sealed or half-sealed cavities, in which some or all of said cavities are in fluid communication with the inflatable bladder, the lower chamber having a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, said outer shroud band connecting the top and bottom layers to form an inflatable bladder.

Abstract: An air-inflated mattress, comprising a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, wherein said shroud band connects the top and bottom layers together to form an inflatable bladder; further comprising a middle layer below said top layer sealed to the top layer. The mattress may also comprise a middle shroud band and an inner shroud band, a plurality of joint spots welded on the bottom side of the top layer, alternatively arranged with anchor separators and a plurality of joint spots welded between the shrouds and means to pass air between the bladder and a plurality of half-sealed sub-chambers created by the joint welds, which slows the spreading speed of the air to the bladder and the chambers, so that the air mattress is even and level and the supporting strength of the air mattress is greatly improved.

Abstract: A swimming pool ladder typically utilized with a large capacity swimming pool for enabling bathers to conveniently enter and exit the pool. In its most fundamental embodiment, the swimming pool ladder includes a first ladder section connected to a second ladder section by a top platform.
