Method, system, base station and data carrier for clash-free transmission between a base station and a number of mobile data carriers
First Claim
1. A method of transmitting signals between at least one base station and a number of mobile data carriers operating in the crypto mode or in the plain mode, wherein[a] the base station emits at least one command signal and/or data signal that is provided with at least one identifying pattern,[b] at least one of the data carriers receives the command signal and/or data signal emitted by the base station that is provided with the identifying pattern,[c] at least one of the data carriers that receive the command signal and/or data signal transmits to the base station a response signal that is a response to the command signal and/or data signal, and[d] the base station receives the response signal transmitted by the data carrier,characterized in that the identifying patternis in the form of at least one first identifying pattern that identifies the crypto mode, for addressing at least one data carrier operating in the crypto mode, andis in the form of at least one second identifying pattern that can be distinguished from the first identifying pattern and that identifies the plain mode, for addressing at least one data carrier operating in the plain mode, wherein the identifying pattern is in the form of at least one code violation, wherein the first identifying pattern and the second identifying pattern differ from one another in respect of their respective lengths.

Abstract
To enable a method and a system, having at least one base station and/or one data carrier, for transmitting signals between the base station and a number of mobile data carriers operating in the crypto mode or in the plain mode, wherein [a] the base station emits at least one command signal and/or data signal that is provided with at least one identifying pattern, [b] at least one of the data carriers receives the command signal and/or data signal emitted by the base station that is provided with the identifying pattern, [c] at least one of the data carriers that receive the command signal and/or data signal transmits to the base station a response signal that is a response to the command signal and/or data signal, and [d] the base station receives the response signal transmitted by the data carrier.

4. A system for transmitting signals, having
at least one base station for emitting at least one command signal and/or data signal provided with at least one identifying pattern, a number of mobile data carriers operating in the crypto mode or in the plain mode, at least one of which is able to be present and/or move in the operating zone or reading zone of the base station, i.e. in particular within the signal transmission range of the base station, receives the command signal and/or data signal, and transmits to the base station at least one response signal that is a response to the command signal and/or data signal, characterized in that the identifying pattern is in the form of at least one first identifying pattern that identifies the crypto mode, for addressing at least one data carrier operating in the crypto mode, and is in the form of at least one second identifying pattern that can be distinguished from the first identifying pattern and that identifies the plain mode, for addressing at least one data carrier operating in the plain mode, wherein the identifying pattern is in the form of at least one code violation, wherein the first identifying pattern and the second identifying pattern differ from one another in respect of their respective lengths.

16. A system for transmitting signals, having
at least one electronic immobilizer of a motor vehicle for emitting at least one command signal and/or data signal provided with at least one identifying pattern, a number of motor-vehicle keys operating in the crypto mode or in the plain mode, at least one of which is able to be present and/or move in the operating zone or reading zone of the electronic immobilizer, i.e. in particular within the signal transmission range of the electronic immobilizer, receives the command signal and/or data signal, and transmits to the electronic immobilizer at least one response signal that is a response to the command signal and/or data signal, characterized in that the identifying pattern is in the form of at least one first identifying pattern that identifies the crypto mode, for addressing at least one motor-vehicle key operating in the crypto mode, and is in the form of at least one second identifying pattern that can be distinguished from the first identifying pattern and that identifies the plain mode, for addressing at least one motor-vehicle key operating in the plain mode, wherein the first identifying pattern and the second identifying pattern differ from one another in respect of their respective lengths, wherein doors of the motor vehicle are locked and the electronic immobilizer is configured to be activated in the crypto mode, wherein the doors of the motor vehicle are unlocked and the electronic immobilizer is configured to be de-activated in the plain mode.
