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.

An improved advertising system can include a location having a substantially large expanse of living greenery, a predetermined design for an advertisement, and a chlorophyll-based agent. The location can be observable by viewers at a predefined minimum viewing distance. The chlorophyll-based agent can be used to paint the predetermined design on the living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. The predetermined design painted on the living greenery with the chlorophyll-based agent can be only viewable by viewers at the predefined minimum viewing distance. Living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When a viewer is nearer than the minimum predefined viewing distance, a difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.

An electronic sign having at least one sectional sign assembly, the at least one sectional sign assembly having a signage support structure and an associated compound structural frame, wherein the compound structural frame has a unitary structural foam construction with a plurality of display module receiving bays, each configured for removably latching therein a plurality of display modules, the signage support structure and the associated compound structural frame cooperating when secured together to form a natural airflow cooling path extending from the top to the bottom of sectional sign assembly to provide sufficient cooling to the plurality of display modules when removably mounted within their display module receiving bays.

An apparatus for a signpost includes a vertical bar comprising a first end and a second end. The apparatus includes an upper bar coupled to the vertical bar. The upper bar includes a center portion substantially perpendicular to the vertical bar and two vertical portions coupled to the center portion. Each vertical portion is coupled to the center portion distal to a connection point to the vertical bar. The apparatus includes a ground anchor coupled to the vertical bar between the upper bar and the second end of the vertical bar. The ground anchor includes one or more spikes oriented toward the second end of the vertical bar, and a tab coupled to the ground anchor and oriented extending away from the ground anchor.

Hook material cut into shapes, symbols, letters or words that are attached to loop pile-type commercial grade carpeting to convey spatial and directional non-verbal messages are disclosed. The hook material adheres to the loop pile-type commercial carpet and has the ability to be changed at any time without the use of adhesives or chemicals. The hook material may further possess a desired color and/or texture as may be desired for a particular application, including areas having heavy pedestrian traffic and/or to enhance child education.

Flat advertising device for placement on the ground, of the type that has a graphic element deformed for better viewing by the observers, characterised in that the graphic element is deformed only along one axis and the said deformation consists of an elongation of less than 100%.

A projection-type image display device includes a first housing and a second housing. The first housing houses a light source unit configured to emit light, an image generating unit configured to modulate the light from the light source unit according to a video input signal to generate image light, and a projecting unit configured to project the image light generated by the image generating unit. The second housing includes an output unit configured to output a light signal and/or an input unit configured to input a light signal which are/is exposed and arranged on a surface of the second housing.

An adjustable stake includes a lower pole including a hollow sleeve, an upper pole configured to be inserted into the hollow sleeve coaxially with the lower pole and to rotate freely therein through a 360 degree arc, and a fixing unit disposed on the lower pole to hold the upper pole stationary with respect to the lower pole.

The invention relates to a display arrangement including a foot which supports a plurality of panels, which are flexibly interconnected by means of connecting elements, a lifting device and a receiving device that can be lowered into the ground. The receiving device is designed to receive the panels, folded together, including the foot and the lifting device. The lifting device is designed to raise the panels out of the receiving device and to lower the panels into the receiving device. The panels can be folded together in a barrel shape around the foot and in particular also around the lifting device. The receiving device is designed to receive the panels folded together in a barrel shape around the foot and more particularly also around the lifting device.

An electronic sign having at least one sectional sign assembly, the at least one sectional sign assembly having a signage support structure and an associated compound structural frame, wherein the compound structural frame has a unitary structural foam construction with a plurality of display module receiving bays, each configured for removably latching therein a plurality of display modules, the signage support structure and the associated compound structural frame cooperating when secured together to form a natural airflow cooling path extending from the top to the bottom of sectional sign assembly to provide sufficient cooling to the plurality of display modules when removably mounted within their display module receiving bays.
