Patent ID: 8633848

Claim:
A method of controlling a device arrangement (D), which method comprises: generating at least one electrical signal in a remote control unit; converting the generated electrical signal into electromagnetic radiation (EM 1 , EM 2 ) according to specific polarization parameters; detecting the electromagnetic radiation (EM 1 , EM 2 ) with a detecting arrangement (R 1 , R 2 ), which detecting arrangement (R 1 , R 2 ) is realized to detect electromagnetic radiation (EM 1 , EM 2 ) with the specific polarisation parameters, to obtain an electrical signal; converting the obtained electrical signal into a device control signal dependent upon the specific polarization parameters; applying the device control signal to a device (L 1 , L 2 , L 3 ) of the device arrangement (D); and operating the device in accordance with the device control signal.
