Shining key trailer for use with e.g. laptop, has time-limited light-labels that are excluded from key associated with lock when reaching border distance to lock, where number of LEDs is arranged in row on location of active transponder

摘要

The trailer (1) has time-limited light-labels that are excluded from a key (5) associated with a lock (4) when reaching a border distance to the lock, where the trailer corresponds to an active transponder (2) with a passively lock radio-frequency identification (RFID) transponder. An optimum number of LEDs (6) is arranged in a row on a location of the active transponder for lighting between the active and RFID transponders. A light guard element (8) allocates a convex lens-like thickening (9) for the LED, where the key is received by a photoconductive and optimum short connector (10).
