  • Patent number: 4419734
    Abstract: An inventory control system for a plurality of storage areas is provided wherein each storage area comprises at least one platform adapted to support a plurality of identical articles, and platform-supporting means including transducer means for providing a first electrical signal which varies in accordance with changes in the load carried by the platform-supporting means. The system also includes signal processing means for processing the first signals and producing in response to each first signal a second signal which is representative of the number of articles supported by the corresponding platform, scanning means for causing each of said first signals to be selectively coupled to said signal processing means, and means for providing an inventory record in response to said second signals.
