  • Patent number: 7133528
    Abstract: An electronic animal lure for generating an animal call pattern by combining actual stored analog animal sounds with a micro controller. The animal sounds are stored in an analog storage device. A micro controller selects and addresses one of the pre-stored sounds then generates the signals to cause the storage device to play back the sound. The micro controller then selects a period of time delay before selecting and addressing the next sound to be played. Both time delays and sound selections are accomplished by use of an algorithm stored in the micro controller. The algorithm uses an onboard timer counter to generate a random number that is placed in a software counter causing the software counter to cycle for a period of time, creating a constantly varying time period between animal calling sounds. The algorithm also uses the onboard timer counter to select one of the stored sounds.
