Abstract
A mobile filing system has an active and passive operator safety system that protects persons and objects in the aisles. The safety system comprises video cameras that view the aisles and the adjacent filed media. A series of images from the video cameras are captured at each of several selected aisle configurations when the aisles are supervised to assure that no persons or objects are in them. The images are stored in a computer. During operation of the mobile filing system, when the aisles are unsupervised, images of the filed media and the aisles are captured when a closing mobile carriage is at each of the selected aisle configurations. The corresponding images captured when the aisle was supervised and unsupervised at the respective aisle configurations are compared. If the compared images differ by more than a predetermined amount, the mobile carriage is prevented from rolling to further close the aisle.
