20160104103 | GAS CYLINDER COUNTING SYSTEM - A gas cylinder counting apparatus that has bins with aligned parallel rows of industrial gas cylinders stored in a cage having upright posts with gas cylinder movement detectors. Gas cylinders in each bin are separated from each other to form a cylinder array. Proximity sensors attached to posts count cylinder removals by changes of state of the cylinder array and report removal of a cylinder from the bin to a local server. When gas cylinders are removed from other cages, local servers report to a remote server and to the management software for gas cylinder ordering and delivery. | 04-14-2016 |
