  • Security system for cigarette display case
    Patent number: 5252948
    Abstract: The system includes optical detectors, a control microprocessor, and an alarm. The detectors optically detect the presence of cartons within the shelf exit openings and emit carton-present signals upon such detection. The microprocessor is responsive to the signals and activates an alarm when a preselected detector signal pattern is observed. In the preferred embodiment, the alarm patterns include four signals within 15 seconds or one signal having a duration of 6.5 seconds.
