Gemini has used the transmitter side of the 4-bit IR remote control system to generate a modulated IR beam.  A modulated IR detector constantly resets a monostable. When the beam is broken the monostable times out and sets a latch to sound the alarm.  The alarm is for use with a car parked outside the home.  If the car is moved, an alarm sound inside the house.
