Abstract: A method (51) for measuring the mass of an object such as a letter (10) in motion. An apparatus (12) for carrying out the present invention includes a pair of rollers (16, 18) through which a letter passes. One of the rollers (16) is driven by a motor (20) which has an associated encoder (22) to give motor positional information to a controller (24).

Prior to obtaining an inertia value with a letter, an initial inertia value is obtained without a letter to get a base inertia. The base inertia is subtracted from the measured inertia with a letter to get a difference ?I.

Abstract: The multiple load sensing multi-load cell scale is described that provides improved utility to scales with multiple decks that share load cells near supports so that more than one load may be determined at the same time on a single scale. In more detail, the scale uses the sectional sensitivities to load movement on the scale decks, load position and individual normalized load cell outputs to provide separate load magnitude measurements on these individual decks. According to the present invention, more than two load cells associated to form a single scale provide outputs that are converted to individual digital representations of the relative force magnitude on each. These magnitudes are related to the effective location of each load cell to provide the load centroid location on the scale when the sum of the products of the effective location and magnitude of each is divided by the sum of the magnitudes.

Abstract: A single vector calibration system is provided which facilitates the calibration of multi-axis load cells, including wind tunnel force balances. The single vector system provides the capability to calibrate a multi-axis load cell using a single directional load, for example loading solely in the gravitational direction.

The system also reduces load application inaccuracies caused by the conventional requirement to generate multiple force vectors. The simplicity of the system reduces calibration time and cost, while simultaneously increasing calibration accuracy.
