1. An apparatus for determining dimensions of a cuboidal object, comprising:
- a longitudinally extending platform having a surface;
a first, downwardly facing distance sensor disposed above the surface of the platform;
a second distance sensor at one side of the platform and facing laterally thereacross; and
third and fourth distance sensors disposed along a longitudinal edge of an opposing side of the platform from the one side, the third and fourth distance sensors, substantially facing each other and facing substantially along the longitudinal edge of the opposing side.

Abstract
A method and apparatus for dimensioning and, optionally, weighing a cuboidal object. Four distance sensors are employed, one downwardly facing the top of the object, one facing one side thereof and two respectively facing mutually parallel sides of the object perpendicular to the one side. Distances are measured between the sensors and the top and sides of the object and subtracted from known distances to determine the length, width, height and spatial volume of the object. The object may be weighed as it is being dimensioned. Spatial volume and a “dim weight” for the object may be calculated.

16. A method for determining dimensions of a cuboidal object, comprising:
-
placing a cuboidal object on a surface of a platform;
aligning mutually perpendicular sides of the cuboidal object to be respectively substantially perpendicular to a downwardly facing first distance sensor, a second distance sensor facing across the platform from one side thereof, and third and fourth distance sensors facing opposing, mutually parallel sides of the cuboidal object perpendicular to the one side thereof;
aligning a side of the cuboidal object parallel with the one side thereof with an alignment surface opposing the second distance sensor;
determining a height of the cuboidal object by determining a first distance between the first distance sensor and the top of the cuboidal object and subtracting the determined first distance from a known distance between the first distance sensor and the platform surface;
determining a width of the cuboidal object by determining a second distance between the second distance sensor and the one side of the cuboidal object and subtracting the determined second distance from a known distance between the second distance sensor and the alignment surface; and
determining a length of the cuboidal object by respectively determining third and fourth distances between the third and fourth distance sensors and the opposing, mutually parallel sides of the cuboidal object and subtracting the third and fourth determined distances from a known distance between the third and fourth sensors. - View Dependent Claims (17, 18, 19, 20, 22)
