Definitions

  • the invention relates to a system comprising a marker comprising a container encompassing an electroluminescent light-emitting element which controllable luminesces.
  • the invention also relates to the use of a system comprising the marker interactively for guiding and controlling movement of objects and subjects.
  • Retro-reflective type markers require illumination with an external source of light, such as the light provided by conventional road-side streetlights.
  • Such streetlights consume a relatively high amount of energy. Since such streetlights are positioned far above the marker, light transfer to the retro-reflective material of the marker is not efficient. Moreover, net energy consumption by the streetlights is further negatively influenced by the fact that such lights are switched on night-time long, at minimum.
  • LEDs have the disadvantage that such LEDs degrade over time and lose power efficiency. LEDs suffer from a change in the wavelength of the emitted light, resulting in a migration in the color spectrum towards a different color. Moreover, high energy consumption by a marker using LEDs is of concern.
  • Such conventional markers have the further disadvantage that the guidance provided by the markers is not specifically directed in any way towards the needs of the vehicle or subject in need of such guidance.
  • a vehicle or subject approaching a conventional marker and being in need of any guidance to be provided by the marker is confronted by a marker not only illuminated at and near the actual position of the subject or vehicle, but in contrast by a marker illuminated over a wide area or distance. This way, receiving the required local guidance by the marker is hampered.
  • a road side marker is described, which marker is provided with e.g. an automated emergency services notification or a traffic alert system.
  • the road side marker has electroluminescent properties and includes an electronic control system.
  • the road side marker is equipped with an electronic circuit to transmit signals to, and receive signals from devices at remote locations. The emitted color is tunable and the marker is actuable.
  • the road side marker of US 2007/0223996 takes the form and shape of a rectangle or cone to be adhered to an individual, moveable object such as a pavement marker, a safety cone, a barrel, a roadside marker pole, a warning sign and the like, all having limited dimensions in the order of lengths of between a few centimeters up to a few tens of centimeters, at most. Indeed, in order to span a significant length of e.g. a road, with the road side marker of US 2007/0223996 , such a series of road side markers is placed at an interval of about a few cars length apart along the side of the road.
  • the distance of the road between two subsequent road side markers is deprived of any object capable of providing any guidance by luminescing. Since a road track requires numerous separately spaced road side markers, all these individual markers have to be integrated separately in the control system. Furthermore, the road side markers are unsuitable for, for example, heavy duty use if such markers were integrated in e.g. road linings on or in the surface of e.g. highways and the like, at the position where vehicles move across the markers, since they lack measures required to resist the accompanied wear.

  • a first aspect of the present invention relates to a system comprising a marker comprising a container, as defined in claim 1
