The invention relates to a method for determining of at least an order of objects O,Otransported by a conveyoralong a conveyor path, wherein each of the objects O,Ocarries an assigned transponder T,Thaving a characterizing code. At least a first radio frequency identification reader R&#x2014;having at least a first reader-antenna Afor generating a first reading field F&#x2014;is arranged with respect to the conveyorand built for identifying the transponders T,Tof the transported objects O,Opassing along or through the first reading field F The following steps are performed: reading out the codes of the transponders T,Tby the first reader Rand generating detection-signals as long as the respective transponder T,Tis detectable by the first reader R, saving the detection-signals linked with a time information, deriving a mean first point of time for each detected transponder T,Tfrom the saved detection-signals and the time information linked therewith by an assessment method&#x2014;wherein the first points of time indicate an estimated discrete point of time for each transponder of passing the first reader R&#x2014;and determining the order of the objects O,Oon the conveyoraccording to the first points of time of each transponder T,T

Method and device for determining of an order of conveyed objects

The invention relates to a radio frequency (RF) system and method for improving the detection efficiency of an identification system including a transponder and a reader. The system () comprises an interrogator reader device () having an interrogator coil antenna () and a transponder () having a transponder coil antenna () and a microchip () Advantageously, the interrogator reader device () comprises a detection portion () including a sensitive signal gain detector (SSGN) for detecting just the presence of the transponder coil antenna () in case of misplacement of the transponder or broken link between the transponder coil antenna () and the microchip (). The invention allows remedying to those potentially dangerous situations that might lead to a misdetection of the transponder ().
