1. An apparatus for weighing and measuring an object, comprising:
- a weighing device comprising a horizontal object support platen supported by at least one load cell; and
three transducers supported in isolation from the horizontal object support platen and aimed in substantially mutually perpendicular relationship to define a three-dimensional volume above the horizontal object support platen of greater extent in each dimension than that of a largest object to be measured, the three transducers each being configured to emit energy signals and to receive energy signals emitted after reflection from an object placed within the three-dimensional volume.

Abstract
An apparatus and method for weighing and non-contact measuring of dimensions of a stationary object wherein the platen on which the object is placed for weighing and measuring is isolated from the support assembly for the dimension measuring sensors for greater sensitivity and accuracy in weight determination. A method of determining object speed of linearly in-motion object, useful for determining object dimensions, is also disclosed.

9. A method for weighing and measuring an object, comprising:
-
supporting an object with an apparatus configured for determining a weight thereof; and
measuring a length, width and height of the supported object without application of weight to the apparatus supporting the object in a manner affecting the determination of the object weight.

10. A method for determination of speed of conveyance of a linearly transported object, comprising:
-
placing an object of known length on a conveying mechanism with the known length in parallel relationship to a direction of linear travel provided by the conveying mechanism;
conveying the object on the conveying mechanism at the speed to be determined;
measuring a time of passage of the object past a selected location while moving at the speed to be determined; and
determining the speed using the known object length and the measured time of passage.
