Bekannt sind zahlreiche verschiedene Arten von Schlössern. Die überwiegende Mehrzahl dieser Schlösser kann als mechanisch eingestuft werden und basiert auf dem Einstecken eines besonders gestalteten Schlüssels in ein Schloß, das Verriegelungsstifte enthält, auf die der Schlüssel abgestimmt ist. Ferner sind Kombinationsschlösser bekannt, die durch manuelles Einstollen einer bestimmten Kombination geöffnet werden kann. Auch Schlösser, die durch Zeitschaltglieder betätigt werden, sind bekannt. Die Verwendung elektronischer Schlösser scheint auf Sicherheitsinstallationen beschränkt zu sein, bei denen der "Schlüssel" aus einer elektronisch passiven Karte besteht, die auf bestimmte Weise mit einer ortsfesten Sende- und Empfangseinrichtung zusammenwirkt. Many different types of locks are known. The vast majority of these locks can can be classified as mechanical and is based on the insertion of a specially designed key into a lock that contains locking pins to which the key is matched. There are also combination locks known, which can be opened by manually entering a certain combination. Even Locks that are operated by time switches are known. The use of electronic locks seems to be limited to security installations where the "key" comes from an electronic Passive card exists, which interacts in a certain way with a stationary transmitting and receiving device.
Bekanntlich kann mit konventionellen Schlössern das Stehlen von Fahrzeugen nicht wirksam unterbunden werden. Insbesondere für Fahrzeuge sind Kombinationsschlösser ungeeignet, weil das Einstellen der Kombination relativ viel Zeit erfordert und weil die Kombination unter Verwendung geeigneter Horchgeräte herausgefunden werden kann. Schösser, die mit Zeitschaltgliedern betätigt werden, sind nicht praktisch und elektronische Schlösser mit passivem Schlüssel sindIt is well known that conventional locks cannot effectively prevent theft of vehicles. Combination locks are particularly unsuitable for vehicles because the combination locks requires a relatively long time and because the combination was found out using suitable listening devices can be. Locks that are operated with timers are not practical and electronic locks with passive keys are

Eine detailliertere Erläuterung der Detektor- und Dekodiervorrichtung erfolgt nun anhand von Figur 2. Ein Fotodetektor 30 reagiert auf die optischen Signale des Senders und liefert entsprechende elektrische Signale an einen Verstärker 32. Das Ausgangssignal des Verstärkers 32 wird einem Impulsformer 34 zugeführt, dessen Ausgangssignale an einen Impulsdemodulator 36 geliefert werden. Der Ausgang des Impulsdemodulators 36 ist an einen Codewortanalysator 38 angeschlossen. Wenn der Codewortanalysator das richtige Codewort empfangen hat, liefert er ein Steuersignal an einen elektronischen Schalter 40. Auf dan Empfang eines unrichtigen Codewortes untox"-bricht der Codewortanalysator dagegen den Erkennungsvorgang für eine vorbestimmte Zeit, um zu verhindern, daß ein Dieb die Aussendung mehrerer Codewörter in schneller Folge veranlaßt. Nach Empfang einer bestimmten Anzahl unrichtiger Codewörter kann ein Alarm ausgelöst werden, um einen Diebstahlsversuch anzuzeigen.A more detailed explanation of the detector and decoder device now takes place with reference to Figure 2. A photodetector 30 reacts to the optical signals of the Transmitter and supplies corresponding electrical signals to an amplifier 32. The output signal of the amplifier 32 is supplied to a pulse shaper 34, the output signals of which are supplied to a pulse demodulator 36 will. The output of the pulse demodulator 36 is connected to a code word analyzer 38. When the code word analyzer has received the correct code word, it supplies a control signal to an electronic switch 40. Upon receipt of an incorrect code word untox "- breaks the code word analyzer, on the other hand, stops the recognition process for a predetermined time in order to prevent that a thief causes the transmission of several code words in quick succession. After receiving a specific Number of incorrect code words, an alarm can be triggered to indicate an attempted theft.
