Abstract: The present invention relates to a system (100) for monitoring an environmental condition in a storm drain (102, 104), the system comprising: A storm drain (102, 104), containing a filter device (134) comprising a filter unit (130) and a floating carrier (132) for carrying the filter unit (130). At least one sensor (106, 108, 110, 112, 114) arranged in the storm drain (102, 104), for determining an environmental condition in the storm drain (102, 104). Wherein the at least one sensor (106, 108, 110, 112, 114) being arranged in communication with a sub node (116, 118) for transmitting data regarding the determined environmental condition in the storm drain (102, 104) to the sub node (116, 118). Wherein the sub node (116, 118) being arranged in communication with a main node (120) for transmitting data regarding the determined environmental condition in the storm drain (102, 104) to the main node (120).

Abstract: An electronic identification tag is made up of at least one cover strip and a carrier strip having an antenna and transponder mounted thereon, and an adhesive to secure the strips together such that the antenna is interposed between the strips, the transponder being pre-programmed to generate a signal having a unique code correlated with indicia on the tag to identify a passenger or luggage. The tag further lends itself well to a novel method of tracking luggage and passengers in a transportation facility.
