  • Method for locating a detection microchip
    Patent number: 7391360
    Abstract: A method is described for locating a detection microchip that transmits a detection signal, which is received and evaluated by a reader. The current distance between the reader and the detection microchip is determined from a run-time dependent feature of the received detection signal and the propagation speed of electromagnetic waves.
    Type: Grant

  • System for the spatial allocation of at least one transponder to the cells of a detection area, base station, and transponder
    Patent number: 6535744
    Abstract: A system is described for the spatial allocation of at least one transponder to cells of a detection area. The cells of the detection area differ by changeable or permanently different properties of an electromagnetic field. By means of the transponder, the properties of the electromagnetic fields of the cells which are capable of reception individually, selectively, or resultantly, are evaluated. Allocation to the cells is effected automatically according to the properties of the individual electromagnetic fields received, or according to the ratio of the proportions of the electromagnetic fields received selectively or resultantly, or according to the proportion predominating in the field strength of the electromagnetic fields received selectively or resultantly.

  • Process and configuration for detecting a transponder with reference to a particular cell of two adjacent overlapped cells
    Patent number: 6424838
    Abstract: A process and configuration used therein for detecting a transponder in a detection region, structured into two adjacent overlapped cells, provide for detecting the transponder with reference to a particular one cell of the two cells.

  • Method of automatically identifying an unknown number of transponders with a reader and identification system for executing the method
    Patent number: 5751570
    Abstract: In a method for automatically identifying an unknown number of transponders, these transponders are put into a dead state by a collision signal transmitted by the reader. Then, each transponder generates its own random dead time and the transponder with the shortest dead time is the first to transmit its data to the reader, while the other transponders are put into an idle state. When the reader has completely received the data of the first transponder, the idle states of the other transponders end and they generate another dead time for themselves. The entire process is then repeated, i.e., the transponder with the shortest dead time transmits its data to the reader, etc. until all transponders have transmitted their data to the reader individually and successively.
