Commissioning load devices via challenge-response-timing
First Claim
1. A commission device configured to commission load devices, which commission device comprisesa first transmitter configured to transmit an activation signal to a load device for activating this load device,a second transmitter configured to transmit a number of challenge signals to the activated load device, which activated load device is configured to respond to the number of challenge signals by sending back a response signal per challenge signal to the commission device,a first receiver configured to receive the response signals from the activated load device, anda controller configured to determine time-intervals present between transmissions of the challenge signals and receptions of the response signals, which controller is further configured to derive a position of the load device from an analysis of the time-intervals.

Abstract
Commission devices (1) comprise first transmitters (11) for transmitting activation signals to load devices (2-6), and second transmitters (12) for transmitting numbers of challenge signals to activated load devices (2) that respond by sending back a response signal per challenge signal to the commission devices (1). The commission devices (1) further comprise first receivers (13) for receiving the response signals and controllers (14) for determining time-intervals present between transmissions of the challenge signals and receptions of the response signals. The controllers (14) derive absolute or relative positions of the load devices (2-6) from analyzes such as statistical analyzes of the time-intervals. Load devices (2-6) comprise second receivers (21) for receiving the activation signals and third receivers (22) for receiving the number of challenge signals and third transmitters (23) for sending back the response signals to the commission devices (1). The load devices (2-6) may further comprise loads (26).
