Abstract: A post sleeve installation system can include a plurality of post sleeve installation devices and at least one spacing beam or mechanism. The spacing beam or mechanism can include end portions that rotate about multiple independent axes and can be coupled to a pair of post sleeve installation devices to determine or control the relative locations and orientations between two post sleeves. The post sleeve installation system can be used to install post sleeves for posts for a fence, a rail or other structure supported by posts.

Abstract: A method of forming a post sleeve within a post hole in the ground to include a post receiving cavity to insertably receive and support a post is provided. The method includes positioning a post sleeve core within the post hole with the aid of an elongate installation member and depositing uncured material into the post hole to at least partially surround the post sleeve core while the post sleeve core is attached to the elongate installation member. The method further includes allowing the uncured material to harden around the post sleeve core to form at least a portion of the post-receiving cavity of the post sleeve and removing the post sleeve core from the hardened material to expose the post receiving cavity to receive and support the post. Other related methods of forming post sleeves are also provided.

Abstract: Interactive systems and methods are provided for designing and constructing fences or other structures supported by posts, including methods which enable users to design custom fence panels and be presented with dynamic visual representations of such custom fence panels.

Abstract: A rocket landing stabilization system can include one or more upright support structures such as posts, columns, or walls, from which one or more stabilizing elements can be supported. The stabilizing elements can be used to stabilize a rocket as it lands at a landing site. The rocket landing stabilization system can also include a cradle, funnel, or cone to catch or otherwise support a rocket as it lands at the landing site. The rocket landing stabilization system can be located on land or at sea.

Abstract: Fence panel display systems can include a unitary foundation including a plurality of steps, at least one rail extending along the width of one of the steps, and at least two clamp assemblies adjustably coupled to the rail. A fence panel can be clamped to the foundation using the clamp assemblies by adjusting the clamp assemblies along the width of the step and by adjusting protrusions extending from main bodies of the clamp assemblies in a direction perpendicular to the width of the step.

Abstract: A system of fence components includes fence posts, fence rails having cavities formed in their ends, and fence rail inserts sized to be positioned within the fence rail cavities. The fence rail inserts and the fence rail cavities include corresponding mating features to allow the fence rail inserts to be positioned and locked within the fence rail cavities. The fence rail inserts also include fastener guides that allow a fastener to pass through to couple the fence rail inserts to the fence posts.

Abstract: A post sleeve includes a reinforced concrete body preformed around a liner that defines a cavity extending longitudinally within the body, sized to receive a post. Standoff ribs run lengthwise within the cavity and extend inward from inner walls of the cavity. A post in the cavity is supported laterally by the standoff ribs. Drain channels between the ribs permit water to flow past the post and exit the cavity via a lower aperture. A drain tube is coupled to the lower aperture, and extends downward where it is covered with gravel at the bottom of a post hole. Concrete is poured around the post sleeve in the hole. The cavity is adaptable to receive posts of varying sizes, and at various depths. A collar closes a space between the post and the top of the cavity, permitting air circulation within the cavity while shedding water and substantially preventing insects from entering the cavity.

Abstract: A system for positioning post sleeves is provided including a plurality of post sleeve positioning devices and a spacing mechanism. Each post sleeve positioning device is configured to receive a respective post sleeve and to enable selective adjustment of a position and orientation of the respective post sleeve. The spacing mechanism is coupleable between the pair of post sleeve positioning devices to determine or control the position and orientation of the post sleeve received by one of the pair of post sleeves positioning devices relative to the post sleeve received by the other one of the pair of post sleeve positioning devices. Related systems and methods are also provided.

Abstract: A rocket landing stabilization system can include one or more upright support structures such as posts, columns, or walls, from which one or more stabilizing elements can be supported. The stabilizing elements can be used to stabilize a rocket as it lands at a landing site. The rocket landing stabilization system can also include a cradle, funnel, or cone to catch or otherwise support a rocket as it lands at the landing site. The rocket landing stabilization system can be located on land or at sea.

Abstract: A fence panel can include a plurality of modular fence panel components that can be assembled modularly to form the fence panel. The fence panel components can include a system of keys and keyways that allow the components to interlock with one another when the fence panel is assembled to lock the components to one another to simplify the assembly process and to minimize the number of mechanical fasteners needed to assemble the fence panel.
