Abstract
A weight measurement apparatus, includes a weight scale having a weight output for providing a weight output signal indicative of the apparent weight of an object being weighed. An accelerometer (or an array of accelerometers) is used to measure a force which contributes to the apparent weight and causes the apparent weight to deviate from the object's true weight. A computer coupled to the scale and the accelerometer computes the true weight of the object from the apparent weight and the accelerometer output. This true weight is displayed on a digital display.
