Abstract
An alarm system senses the presence of a person sufficiently near a protected object, such as an automobile, to inflict damage thereto, and provides verbal warnings to the person that he or she must step back from the object or an alarm will be sounded. The alarm system includes a proximity detector that senses the proximity of a person to the protected object and means for generating vocal signals using synthetic speech generation circuits. Such vocal signals instruct the person to back away from the protected object, thereby preventing the person from inflicting any damage to the object. The user may select various operating modes and performance options in how the system is used.
