Title: Electronic anti-theft device for motorcycles
Inventor: THIEL MICHAEL
IPC: B60R25/10
Filed: 1984-09-19
Abstract: The invention relates to an electronic anti-theft device for motorcycles. By means of an integrated circuit the transistor T2 can trigger an alarm via the relay K1. The integrated circuit is made ready to issue an alarm via the transistor T2 when the voltage is switched off at its base. The switching off of the voltage is delayed via an RC element. The duration of the alarm is determined by an RC element R3 and C2. An alarm is triggered via the drive 2 of the integrated circuit. The drive 2 is connected via three separate parallel alarm lines to alarm generators. The parallel connection is possible by means of the capacitors C1, C6 and C7. The connection of the mercury switch Hg and of the transistor T3 permits an alarm to be triggered both when closing and when opening the Hg switch. By means of the circuit, insensitivity to fluctuations in DC voltage is obtained. The circuit is sensitive to inductive fluctuations in voltage in the switched-on state. <IMAGE>
