Abstract: A product order fulfillment system of mixed product units, the system includes a storage array, an automated transport system, with at least one asynchronous transport system, for level transport, and a lift for between level transport, communicably connected to the storage array so as to automatically retrieve and output, from an output of the storage array, product units distributed in cases in a common part of the storage array. The at least one asynchronous transport system, and the lift are configured so as to form more than one transport echelon, each echelon being communicably connected with the common part and the output, and each effecting orthogonal sortation, corresponding to the transport echelon, of the product units distributed in the common part, so that sorted mixed output product units of the corresponding transport echelon are in predetermined sequence.

Abstract: Systems and methods for manufacturing a vacuum device, such as an electron emitter, that includes a foil exit window palced over and joined to a support grid. In one particular method, the vacuum chamber of an electron emitter has a thin foil forming an exit window at one end. The thin foil may be titanium or any suitable material and the foil will typically enlarge during a bonding process that attaches the foil to the support grid. In one manufacturing process, the support grid is provided with a surface that has contours, typically being smooth recessed surfaces, that the foil once enlarged can lie against as the vacuum pulls the foil against the grid.
