Abstract: A weight system includes a cart comprising a plurality of wheels and a frame on the plurality of wheels. The frame has a plurality of rails, and a basket is suspended from the plurality of rails of the frame. A weight sensor is coupled at one end to the suspended basket and attached at another end to one of the plurality of rails of the frame from which the basket is suspended. The weight sensor is adapted to detect weight change of the basket when an item is placed into or removed from the basket.

Abstract: A system for locating a mobile container within a facility comprises an optical sensor system with an optical sensor fixed to a frame of the container. The optical sensor is pointed away from the container in a direction facing a region of the facility (e.g., ceiling or floor) where one or more distinctive physical features are expected to be found. Each distinctive physical feature of the facility is associated with a location in the facility. The optical sensor is adapted to capture an image of that region of the facility. A computing system includes a processor configured to receive the image from the optical sensor, to determine that a physical feature found in the image matches one of the distinctive physical features of the facility, and to identify the container as being at the location in the facility associated with the matching distinctive physical feature.
