Abstract
A weighing scale having a display and processor for determining and identifying the optimal position coordinates for a load placed on the weighing scale includes a platform and a plurality of support assemblies, each containing a load cell for receiving the weight of the load. The display includes a meter or other graphical display that identifies position coordinates along with the determined numerical weight. Individual outputs from each of the plurality (e.g. 4) of load cells are received by a processor configured to compute x,y vector coordinates associated with the weight parameters for each load cell. The determined current or actual load position relative to an optimal position is calculated and displayed along with the weight.
Claims26
A weighing scale comprising:
- a platform for supporting a load to be weighed by the scale, the platform defining an optimal weighing position for optimally positioning the load thereon;
- a plurality of load cells, each of the load cells for sensing a portion of the load's weight and outputting an electrical signal containing data indicative of the sensed portion of the load's weight;
- and
- a processor, using the data contained in the electrical signals outputted by the load cells, for determining a total weight of the load, determining an actual position of the load on the platform, and determining how the actual position of the load on the platform deviates from the optimal position;
- and
- at least one of an indicator for indicating that the load is in the optimal position and a display for displaying the deviation of the actual position of the load from the optimal weighing position, so that the load can be repositioned to the optimal weighing position.
A method for accurately positioning a load on a platform of a weighing scale, the method comprising the steps of:
- providing a plurality load cells, each of the load cells for sensing a portion of the load's weight and outputting an electrical signal containing data indicative of the sensed portion of the load's weight;
- determining an actual position of the load on the platform, and how the actual position of the load on the platform deviates from an optimal weighing position using the data contained in the electrical signal outputted by the load cells;
- and
- indicating that the load is in the optimal position.
