Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT 2-Wire MOTORCYCLE ALARM The following statement is a full description of this invention 00 Innovation Patent Specification 2-Wire Motorcycle Alarm O Inventor Michael Gergos 2-WIRE MOTORCYCLE ALARM SPECIFICATION DESCRIPTION Overview: Motorcycle alarms commonly connect to a motorcycle's electrical system via several electrical interconnections making installation complex, costly and time consuming.
Activation and deactivation of such alarms is typically the function of a 'key fob' transmitter. Such remote control devices are prone to failure given the outdoor nature of 00 their existence.
The 2-Wire Motorcycle Alarm does not require key fobs to operate. Arming and disarming of the alarm is a function of the motorcycles existing ignition key.
The 2-Wire Motorcycle Alarm connects to the motorcycles electrical system using only 2 conductors, eliminating the need for complex wiring harnesses and timely installation.
Operation of the 2-Wire Motorcycle Alarm is as follows; When the motorcycles ignition key is switched OFF ONCE, the alarm will arm automatically (after a short delay). When the motorcycles ignition key is switched OFF TWICE, the alarm will disarm.
The alarm may incorporate sensors, audible siren, GPS positioning, telecommunications and or telemetry capabilities.
Background: In 1992 the Australian commonwealth legislated (for safety reasons) that all motorcycles sold in Australia should have daylight running lights (DRLs). Although this legislation was relaxed in 1997, many other countries across Europe and the US maintain this position thus motorcycle manufacturers typically omit the headlamp switch and simply connect the head and tail lights directly to the ignition circuit as shown in Figure 1.
As a consequence of this electrical topology, the following innovative steps are possible; Innovative step 1: Auto arming whenever the ignition switch is turned off The inherent low impedance of a motorcycle's head and tail lamp provide a virtual earth capable of sinking significant currents. By using this 'virtual earth' in combination with the positive battery terminal, a 12 Volt source is available only when the ignition switch is in the OFF position.
Page 2 of 6 00 Innovation Patent Specification 2-Wire Motorcycle Alarm O Inventor Michael Gergos When the ignition switch is in the ON position, this power source is effectively short circuited, generating a 0 Volt source. In simple terms; the alarm is wired 'across' the ignition switch.
In conclusion, the alarm is powered ON whenever the ignition is switch is OFF, and powered OFF whenever the ignition switch is ON.
Given some simple microcontroller functionality to provide a suitable delay, the 2-Wire Motorcycle Alarm can be made to 'Auto Arm' whenever the ignition is switched OFF.
00 Innovative step 2: Disarming upon switching the ignition off twice N This process is done electronically. Many methods are possible. The alarm monitors the state of the ignition key and changes the status of the alarm as required.
One such method uses a capacitor to briefly store a charge when the alarm powers up.
The charge on this capacitor is first checked to verify if the alarm was powered up recently or not. From this capacitor charge, the alarm can determine whether to power up in the armed mode or in the disarmed mode.
Connection Methodology: Note from Figure 1 that the tail lamp, instrumentation lamps are directly connected to the ignition switch via the fuses making these suitable connection circuits for the lamp wire.
The brake lamp on the other hand is not permanently connected to the ignition circuit thus it is not a suitable connection point for the lamp wire.
The headlamp circuit is a special case whereby one of the lamps is always connected to the ignition circuit as high low beam switches are generally 'make before break' type devices. As such, the headlamp circuit makes a suitable connection point provided connection is made to the ignition side of the high low beam switch.

Claims (3)
1. The alarm shall use only 2 conductors to connect to the motorcycles electrical system.
2. The alarm shall source its power from the positive battery terminal and the positive wire of any low impedance load (eg a lamp) directly connected between the ignition circuit and the earth of the motorcycle. See Figure 1.
3. Arming and disarming of the alarm shall be a function of the motorcycles existing ignition key. Inventor: Michael Gergos Date: 5 h of June 2008 Page 4 of 6
