Abstract: A system for calibrating a robotic tool includes a housing including an aperture for receiving the robotic tool, an image generating device disposed in the housing and positioned to generate an image of the robotic tool received through the aperture of the housing, wherein the image generating device generates an image signal representing the image of the robotic tool, a light source disposed in the housing to backlight the robotic tool received through the aperture of the housing, and a processor responsive to the image signal for calculating and monitoring a configuration of the robotic tool.

Abstract: A food tray comprising a frame having a plurality of apertures therein. The apertures generally correspond to the configuration of the respective food container to be engaged therein. Each food container has a pair of parallel ridges extending about its perimeter so as to present a slot therebetween. The slot of each container engages the portions of the frame which define each aperture. Each food container is thus releasably engageable with the frame. The tray enables a plurality of initially separate containers to be separately heated and/or chilled prior to releasable engagement with the frame.

Abstract: A top gap folding box having four top flaps and a top closure by which the flaps are engaged. Each flap interlocks the adjacent flaps by means of a pair of incisions in the outer edge of the flap which each engage an associated incision in each of the adjacent flaps. The incisions are of a configuration permitting smooth engagement. The material of which the box is made is of a stiff nature, having resistance to bending.
