An interlocking paver system including a polygon paver and a spacer paver is provided. The polygon paver may have a top level having a top level polygon paver perimeter and a bottom level secured to and protruding from the top level and having a bottom level polygon paver perimeter contained within the top level polygon paver perimeter. The spacer paver may have a top level having a top level spacer paver perimeter and a bottom level secured to and protruding from the top level and having a bottom level spacer paver perimeter extending beyond an entirety of the top level spacer paver perimeter The spacer paver may be configured to selectively interlock with the polygon paver. The top level spacer paver perimeter, top level polygon paver perimeter, and bottom level spacer paver perimeter are different from one another.

An interlocking paver system including polygon and spacer pavers. The polygon paver has a longitudinal axis extending from a first to a second side and a transverse axis orthogonal to the longitudinal axis and extending from a third to a fourth side. The spacer paver has a longitudinal axis extending from a first to a second side and a transverse axis orthogonal to the longitudinal axis and extending from a third to a fourth side. Both the polygon and spacer pavers are symmetrical about the longitudinal and transverse axes. The spacer paver is configured to selectively interlock with the polygon paver with either of the third or fourth side of the polygon paver adjacent either of the first or second side of the spacer paver and either of the first or second side of the polygon paver adjacent either of the third or fourth side of the spacer paver.

A vertiport for an aircraft. The vertiport includes a landing platform that includes a landing surface and a plurality of primary through-openings, wherein the landing platform at least partially defines a primary chamber subjacent to the landing platform, the primary chambering having a primary chamber volume, and wherein the plurality of primary through-openings are in fluid communication with the primary chamber. The disclosed vertiport further includes an air moving unit positioned to withdraw air from the primary chamber.

A helipad includes an LED matrix built directly into the landing surface. LEDs within the matrix can be illuminated in controlled patterns to create visible objects to convey information to the pilot of an aircraft landing at the helipad and other personnel. The LEDs can be RGB color-change LEDs that are controlled to output selected colors, and can be activated with variable intensity. One of the patterns can be an arrow aligned with the wind direction as determined by an adjacent windsock, and another pattern can be determined by wind velocity as determined by an adjacent anemometer.

Offshore station, having a metal structure, wherein the metal structure (4) has watering regions (6) which are exposed to natural watering (22), wherein the metal structure (4) has sheltered regions (8) which are exposed to natural watering (22) only to a limited extent, if at all, having at least one cleaning device (14), wherein the cleaning device (14) has at least one collecting device (16), at least one line system (18) and outlet openings (20), wherein the collecting device (16) is designed for collecting rainwater (22), wherein the line system (18) is connected to the collecting device (16) and is designed for distributing the rainwater (22), and wherein the outlet openings (20) are designed for flushing the sheltered regions (8) with rainwater (22).

A modular landing port for use on a top of a building structure. The modular landing port includes a base portion. One or more landing module extend from the base portion. The one or more landing modules have a first end provide proximate the base portion and a second end spaced from the base portion. Each of the one or more landing modules have a landing/take-off zone proximate the second end and at least one loading/unloading zone proximate the first end. The landing/take-off zone and the at least one loading/unloading zone are configured to receive a vertical take-off and landing aircraft.

An overpass structure with vertical interchange arrangement for crossroads includes a transverse roadway at a bottom level, a pedestrian walkway in the middle level and a longitudinal road bridge at an upper level. The vehicle roadways on and under the bridge are connected by two ramp units. The pedestrian walkway is a pedestrian platform with an interchange platform provided on top. The interchange platform is located between and connected to two roadways of opposite directions on the longitudinal road bridge in the upper level. The leftmost lane along a forward moving direction of vehicle on the bridge in the longitudinal road bridge is defined as a universal lane of the longitudinal road bridge. The rightmost lane along a forward moving direction of vehicle under the bridge in the transverse roadway is defined as a universal lane of the transverse roadway. The interchange platform is connected to four universal lanes.
