Abstract: Suitcases with internal load determination devices determine the weight of a suitcase without requiring the user to lift the loaded suitcase. A sensor grid suspended within the interior of the suitcase's bottom is attached to sensors. When a load is placed on the sensor grid, the force exerted by the sensor grid on the sensors is measured and communicated to a CPU. The CPU calculates the weight of the load and displays it to the user on an electronic display. An on/off switch toggles the display between showing the net weight of the load and the gross weight of the loaded suitcase, as well as controlling the flow of electricity from a battery to the CPU, display, and sensors. The suitcase has a handle that extends over the display, feet, wheels, and latches. A method for using the suitcase with internal load determination device is also disclosed.
