Abstract: A portable wireless charging system is incorporated inside a carrying device that has a plurality of walls and an interior. The portable wireless charging system has a transmitter positioned at a first fixed location at an inner surface of one of the walls, a mobile power supply positioned adjacent the transmitter and electrically coupled to the transmitter, and a receiver positioned at a second fixed location at an outer surface of the one of walls, with the second fixed location aligned with the first fixed location. A barrier is positioned between the transmitter and the receiver, and a first pocket positioned at the outer surface about the second fixed location. A portable device that includes a battery to be charged can be retained inside the first pocket to be charged.

Abstract: An inflatable product has a first layer and a second layer, each layer having a peripheral edge, with the first and second layers joined together along their peripheral edges to define an internal space for receiving air or fluid. Each layer has a uniform thickness throughout except that the thickness along the peripheral edge of each layer is greater than the thickness of the rest of the layer. A plurality of tension members can also be provided inside the internal space, each tension member having a first end that is joined to an inner surface of the first layer, and a second end that is joined to an inner surface of the second layer. Each tension member has a uniform thickness throughout except that the thickness along the first and second ends is greater than the thickness of the rest of the tension member.

Abstract: An electrical charging system includes a charging socket and a standby battery product. The charging socket has a socket casing, and a power input interface on the socket casing and electrically connected to a first conductive contact that extends above the socket casing. The standby battery product has a battery casing with a battery housed inside the battery casing, the battery casing further including a conductive pin and a second conductive contact, with the conductive pin and second conductive contact electrically connected to the battery. When the battery casing is placed on top of the socket casing, the conductive pin is aligned with, and contacts, the first conductive contact, creating a charging path that is defined by the power input interface (which receives external power), the first conductive contact of the socket casing, the conductive pin of the battery casing, and the electricity storage unit of the battery product.

Abstract: A housing has an upper end, a lower end, and an opening extending between the upper and lower ends, the housing being sealingly attachable to an inflatable device. A check valve has a body member with an upper end, a lower end, an outer surface sized and shaped to be selectively matingly received in the opening of the housing, and an inner surface defining a passageway. The check valve is coupled to the housing by a first tether. A cap has an upper end, a lower end, and an outer surface sized and shaped to be selectively matingly received in the passageway of the check valve. The cap is coupled to the housing by a second tether.

Abstract: A power supply has a generally rectangular housing that has a length of about 11 inches and a width of about 8.5 inches, with a thickness of less than 5.2 cm. A rechargeable battery is housed inside the housing, and a power bay is provided on the housing and coupled to the battery inside the housing.

Abstract: A spa assembly has a pool assembly having an enclosing body defining an interior, the body made of a soft material and further including a drain pipe, an air inlet, a water inlet and a water outlet provided in the body. The spa assembly also includes a framework assembly having a plurality of beams, legs, and fittings that connect the beams and the legs together, with the beams and the legs positioned outside the enclosing body. The spa assembly also includes a wall assembly having a plurality of vertical wall supports, and a plurality of horizontally-oriented wall panels that are coupled to the plurality of vertical wall supports, with the wall supports and wall panels positioned outside the framework assembly.

Abstract: A spa pool assembly has a pool having an enclosing wall and a base that together defines an interior. The base has a plurality of inflatable sections that are divided by a plurality of air passages that includes a first air passage that has a plurality of small bubble openings, and a second air passage that has a plurality of large bubble openings. The small bubble openings eject bubbles that are smaller in size than the bubbles ejected from the large bubble openings. The spa pool assembly can also include a bubble controller that controls the ejection of bubbles from the small bubble openings and the large bubble openings.

Abstract: A spa pool assembly has a pool having an enclosing wall and a base that together defines an interior. The base has a plurality of inflatable sections that are divided by at least one air passage. A hose delivers air from outside the pool to the air passage, with the hose extending partially inside the enclosing wall and having a U-shaped section extending outside the enclosing wall at a vertical level that is higher than the top of the enclosing wall.

Abstract: A liquid enclosure has an automatic air bleeding valve which has a first stage wherein the fluid pathway is open and a one-way valve is interposed in the fluid pathway; a second stage wherein the fluid pathway is open and circumvents the one-way valve; and a third stage wherein the fluid pathway is closed. A float automatically transitions the valve from the first, then second, then third stage as a level of the liquid in the liquid holding chamber rises from below the first to above the second predetermined level, and the valve automatically returns from the third stage to the second stage, then to the first stage as the level of the liquid in the liquid holding chamber lowers from above the second to below the first predetermined level.
