  • Ignition interlock device with rolling retest and motion detector
    Patent number: 8640813
    Abstract: A breath alcohol ignition interlock device. The breath alcohol interlock device includes an ignition interlock system for use with a vehicle, the interlock system requiring a successful breathalyzer test to initiate operation of a motor of the vehicle, the interlock system including a CPU. A vehicle computer that controls functions of the vehicle related to motion receives a signal from the interlock system of a successful breathalyzer test to permit operation of the motor vehicle. A motion detection device associated with the vehicle determines when the vehicle is placed into motion. The motion detection device provides a signal to the CPU of the ignition interlock system when vehicle motion is detected. The CPU of the ignition interlock system initiates a breathalyzer retest algorithm upon receiving a signal from the motion detection device that the vehicle is placed in motion.
