Abstract: The present disclosure is directed towards skimmer systems for above-ground pools. In particular, the present disclosure relates to skimmer systems that are easily installed to the side wall of an above-ground pool. In addition, aspects of the present disclosure relate to a skimmer system for an above-ground pool that provides for an improved watertight seal between the skimmer system and the side wall of the pool. Further, aspects of the present disclosure relate to a weir that is easily installed into and removed from a skimmer system according to a user's needs.

Abstract: Aspects of the present disclosure relate to a safety mechanical system including a latter and a barrier for use with a an above-ground swimming pool that is easy to install and provides safety from children accessing the pool via the ladder. Certain aspects of the present disclosure relate to a safety mechanical barrier that blocks access to the ladder itself, thereby restricting access to an above-ground pool by unsupervised minors.

Abstract: An air temperature control system controls the air temperature inside of an air mattress. The air temperature control system includes an air intake component having inner and outer seals to inhibit or facilitate the flow of air into and out of the air mattress. The air temperature control system also includes a temperature control element in fluid communication with the air intake component. The temperature control element is positioned within the air mattress inside of the outer seal. The air temperature control system further includes a controller configured to direct the air intake component to open and close the inner and outer seals and operation of the temperature control element.

Abstract: Methods and apparatus are described for a two-axis tracking mechanism for a concentrated photovoltaic system. Two or more components forming the support structure of the two-axis tracker mechanism, which are assembled in the field and manufactured to allow one or more lasers to align the support structure of the two-axis tracker mechanism in three dimensions, vertical (X) dimension, horizontal (Y) dimension, and diagonal (Z) dimension, at a site where the concentrated photovoltaic system is to be installed. Adjustable leveling mechanisms are built into the two or more components forming the support structure.

Abstract: Methods and apparatus are described for a two axis tracking mechanism for a concentrated photovoltaic system. Two or more paddle structures containing multiple CPV modules are installed onto each tilt axle on the common roll axle as part of the two-axis tracking mechanism's solar array. The two or more paddle structures couple across the common roll axle on that tilt axle. The common roll axle and each paddle assembly are manufactured in simple modular sections that assemble easily in the field while maintaining the alignment of the tracker assembly.

Abstract: Methods and apparatus are described for a concentrated photovoltaic system. A method of creating a paddle structure with a set of solar receivers that are aligned within and mechanically secured in place in each module contained in a paddle structure. Each solar receiver is assembled and aligned, where the assembly of the solar receiver establishes the alignment of the secondary optic to the photovoltaic solar cell. The assembly of a module with its set of solar receivers establishes the alignment in three dimensions the solar receivers with each other. Individual parts making up the receiver are 1) shaped, 2) sized, 3) keyed, 4) pinned and 5) any combination of these to fit together in only one way so that all of the solar receivers containing the photovoltaic solar cell maintain their alignment when installed in a given CPV module.

Abstract: Methods and apparatus are described for a two axis tracking mechanism for a concentrated photovoltaic system. A solar array of the two axis tracking mechanism is structurally broken up to have multiple independently movable sets of concentrated photovoltaic solar (CPV) cells. Further, the remainder of the two-axis tracker is manufactured in simple sections that assemble easily in the field while maintaining the alignment of the tracker assembly. The CPV cells are located in two or more paddle assemblies, and the paddle assemblies couple to a common roll axle. Each of the multiple paddle assemblies contains its own set of the CPV solar cells that is independently movable on its own tilt axle from other sets of CPV cells on that two axis tracking mechanism. Each paddle assembly has its own drive mechanism for that tilt axle.
