Abstract: Automated inventory management and material (or container) handling removes the requirement to operate fully automatically or all-manual using conventional task dedicated vertical storage and retrieval (S&R) machines. Inventory requests Automated vehicles plan their own movements to execute missions over a container yard, warehouse aisles or roadways, sharing this space with manually driven trucks. Automated units drive to planned speed limits, manage their loads (stability control), stop, go, and merge at intersections according human driving rules, use on-board sensors to identify static and dynamic obstacles, and human traffic, and either avoid them or stop until potential collision risk is removed. They identify, localize, and either pick-up loads (pallets, container, etc.) or drop them at the correctly demined locations. Systems without full automation can also implement partially automated operations (for instance load pick-up and drop), and can assure inherently safe manually operated vehicles (i.

Abstract: A mask system and device for an individual including a front portion defining a surface which is generally C-shaped and preferably forms bights or curved surfaces in both the horizontal and vertical cross section. The surface extends from and conforms to a position below the eyes to an area below the chin. The mask also includes sides integrally formed with the front portion and positioned adjacent the cheeks or jaw. The surface, in part, defines a cavity between the sides adjacent the individual's nose and mouth. An exhaust device is affixed to a defined channel formed on one lateral side. The opposite lateral side forms an intake port. Securing straps are provided to retain the mask portion adjacent the face. The exhaust device is provided at the free end of a tube which communicates with the side channel to create a continuous air flow across the cavity and to exhaust stale exhaled air.
