Abstract: Systems and techniques are presented for processing a user through a paid entry gate using a mobile device. The mobile device receives a beacon packet from a first wireless beacon and wakes up an application. The application wakes up by transitioning to an active or background execution state. The application transmits validation data to a computer server system and the computer server system validates an account of the user. The mobile device receives a beacon packet including a gate identifier that is a unique identification of the paid entry gate from a second wireless beacon and transmits the gate identifier to the computer server system. The computer server system receives the gate identifier, debits the account of the user, and transmits a signal to a gate entry device associated with the gate identifier to grant the user passage through the paid entry gate.

Abstract: The invention relates to a rescue arrangement for effecting a rapid descent from a higher level to a lower level. The rescue arrangement comprises guiding means which extend between the higher level and the lower level, as well as carrying means which are connectable to the guiding means for carrying a person or another object from the higher level to the lower level along the guiding means. Magnetic braking means, which comprise a series of permanent magnets, are located on the guiding means or the carrying means for slowing down the carrying means at least near the lower end of the guiding means.

Abstract: A rescue arrangement for effecting a rapid descent from a higher level to a lower level. The rescue arrangement comprises guiding means which substantially extend between the higher level and the lower level. Further it comprises carrying means which are connectable with the guiding means for carrying an object, in particular a person, from the higher level to the lower level via the guiding means. It also comprises first braking means located at the guiding means near the lower level for slowing down and/or stopping the carrying means near the lower level. The guiding means comprise at least two substantially parallel tracks, wherein the carrying means are adapted to be connected to at least two of the tracks.
