  • light transmitting compounds other than standard acrylic glass or PMMA that are slightly more elastic but have less conductance may be used as the light transmitting member 42.
  • the fiber optic communication rope 10 has the potential for extensive use by the caving community, the cave rescue community and the National Cave Rescue Commission. It may also be used by other climbing groups that require communication when being connected via rope. Groups that may get the most use out of this invention are the SAR community and the military. SAR units utilize rope for a large variety of rescue missions; including recovery from crevasses, off the side of cliffs, down sink holes, and within collapsed buildings. These SAR units presently may use radios for communications. However, the present invention may serve as a back-up form of communication or a primary form of communication, as it is water resistant and has no moving parts. The present invention is also useful in military applications requiring silent communication, including by special operations units.

Abstract

L'invention concerne une corde de spéléologie/d'escalade pourvue d'un élément de transmission de lumière enfermé qui permet une communication entre des individus utilisant la corde. L'élément de transmission de lumière s'étend à travers l'intérieur de la corde de spéléologie/d'escalade et n'est pas obstrué à chaque extrémité. L'élément fait fonction aussi bien de capteur que d'émetteur d'une source lumineuse. Lorsque de la lumière est projetée sur une extrémité de la corde, elle sera transférée à travers l'élément de transmission de lumière de la corde et émise à l'autre extrémité où elle peut être vue ou détectée par un dispositif attaché à la corde. La corde peut comprendre une ampoule concave à diodes électroluminescentes (DEL), attachée amovible, fournissant une source lumineuse. Des adaptateurs pour téléphones cellulaires peuvent être prévus pour produire des signaux lumineux ou pour les traiter pour des communications. Ces éléments permettent des communications rapides pour les personnes utilisant la corde à des endroits où elles ne peuvent pas se voir ou s'entendre.
