A universal fastener is provided. The universal fastener is connectable to a buryable element such as a pipe. A marker may be removably attached to the fastener to extend away from the buryable element allowing it to be easily identified once buried.

A portable sign system suitable for advertising signs removably inserted into the earth, such as real estate signs, has a display frame for holding a sign placard, frame sides, and separate ground stakes. Each of the ground stakes can be releaseably connected to one of the frame sides or bottom frame in one of two positions. In the first position, the ground stake is extended from the respective frame side so that the ground stake can be inserted into the ground; in the second position, the orientation of the ground stake is reversed when connected to the frame side or is laid parallel to the bottom frame, so that the overall length of the portable sign system is reduced from that of the first position. The reduction in length allows the portable sign to be easily loaded into the trunk of a vehicle, for example.

In a viewing object display set, it is possible to prevent a reduction in a sense of reality when a viewing object is seen. Specifically, the display set for viewing the viewing object includes the viewing object that is attached to a display surface and an object for visual effect that is provided on a viewing position side with respect to the viewing object and shields at least a portion of the viewing object. The object for visual effect is arranged so as to shield the boundary between the viewing object and the display surface.

A parking space sign system that is mountable to existing parking bumpers or includes a flexible support structure for placement in parking spaces with parking bumpers, a frame mount having at least one transparent frame sleeve formed by sleeve flanges, at least one panel with indicia on its face and at least one mounting aperture for mounting the frame to a parking bumper with hardware or slotted end caps instead of mounting apertures in the frame mount for sealing the ends of the frame mount and securing it to a parking bumper.

A method of converting an existing signage mounting structure to an electronic sign comprises using an installation kit for providing and installing at least one section sign assembly, loaded with a plurality of display modules and having a power routing system with a plurality of individual power extensions extending from a single node to a plurality of display module receiving bays node receptacles, wherein passageway openings at a rear portion of the at least one sectional sign assembly facilitate replacement of individual ones of said plurality of display modules from a rear side of the sign construction, and coupling said single node to a source of power for completing the conversion.

A graphic assembly, such as a floor or road surface sign for vehicle traffic and/or pedestrian traveled areas, is provided. The graphic assembly can include a polymeric substrate layer fixed to a fabric layer that is positioned between the polymeric substrate layer and an adhesive layer. Further, the graphic assembly can comprise a top surface that includes a plurality of surface enhancement particles embedded within a particle receptive layer that is adjacent to the polymeric substrate layer. The plurality of surface enhancement particles include reflective particles and anti-skid particles.

A high visibility aerial landing system for providing improved visibility and landing indication at short range or close range for a helicopter to help distinguish between safe or preferred landing zones from hazardous landing zones. The system has a flexible panel, a mooring assembly, and an indicator system. Further embodiments are specialized to be carried by the EMS or hikers.

An airport airside advertising system 1 displays advertising to passengers of adjacent commercial aircraft. An advertising billboard 7 or 7A is disposed on the airside of an airport adjacent to a runway, taxiway or apron 2, 3, 4 and 12. The advertising billboard 7 or 7A is configured to face a direction substantially perpendicular to the direction of movement of an adjacent aircraft 11 during landing, take off, taxiing or temporary parking thereof, the billboard 7 or 7A dimensioned to display advertising visible to passengers in adjacent commercial aircraft 11. The advertising billboard 7 or 7A has one or more sensor elements 8 associated therewith and configured to provide an actuation signal in response to detection by one or more sensor elements 8 of an adjacent aircraft 11 within a predetermined range.
