Abstract

A volume measurement apparatus and method of use. The volume measurement apparatus comprises a vertical leg attached to a horizontal leg, and at least one sensor attached to the legs. At least one measuring wheel is rotatably attached to the volume measurement apparatus, and is electrically connected to a measuring wheel travel detection means. A volume measurement means is electrically connected to the measuring wheel travel detection means and to the at least one sensor. The method of use includes the steps of rolling the volume measurement apparatus past an object whose volume is to be measured, such that the sensors will scan cross sectional areas of an object embraced within the volume measurement apparatus vertical leg and horizontal leg at pre-set intervals, figuring only the area that the sensor(s) report as solid, which is the object cross section return, and summing the products of the object cross section returns multiplied by the increment.

Claims

1. A volume measurement apparatus comprising a vertical leg attached to a horizontal leg, a first sensor disposed at an extreme of said vertical leg opposite said horizontal leg, a second sensor disposed at an extreme of said horizontal leg opposite said vertical leg, a third sensor disposed at an intersection of said vertical leg and said horizontal leg, and a volume measurement means electrically connected to the sensors, said sensors being mapping type sensors which both emit a signal and detect a signal return reflected from an object being scanned, said signal return defining a contour of the object being scanned, whereby a shape of the object being scanned is defined in said return.

2. The volume measurement apparatus of claim 1 further comprising at least one measuring wheel rotatably attached to said volume measurement apparatus, and a measuring wheel travel detection means electrically connected to said at least one measuring wheel and to said volume measurement means.

3. The volume measurement apparatus of claim 2 wherein said vertical leg and said horizontal leg are extendible, whereby said volume measurement apparatus may be easily transported and stored.

4. The volume measurement apparatus of claim 3 further comprising a vertical leg extension measurement means electrically connected to said volume measurement means, and a horizontal leg extension measurement means electrically connected to said volume measurement means, whereby extensions of said vertical leg and said horizontal leg may be measured.

5. The volume measurement apparatus of claim 2 wherein said measuring wheel is rotatably attached to said volume measurement apparatus at an extreme of said vertical leg opposite said horizontal leg.

6. The volume measurement apparatus of claim 5 further comprising a measuring wheel rotatably attached to said volume measurement apparatus at an extreme of said horizontal leg opposite said vertical leg.

7. The volume measurement apparatus of claim 6 further comprising at least one measuring wheel rotatably attached to one of the legs at an intersection of said horizontal leg and said vertical leg.

8. The volume measurement apparatus of claim 1 wherein said sensors are miniature radars.

10. The method of measuring volume of claim 8 further comprising the intermediate steps of:

A1. Resetting said volume measurement apparatus to indicate zero volume measured; and

A2. Initiating a volume measurement function of said volume measurement apparatus.

9. A method of measuring volume using a volume measurement apparatus, said volume measurement apparatus comprising a vertical leg attached to a horizontal leg, a first sensor disposed at an extreme of said vertical leg opposite said horizontal leg, a second sensor disposed at an extreme of said horizontal leg opposite said vertical leg, a third sensor disposed at an intersection of said vertical leg and said horizontal leg, at least one measuring wheel rotatably attached to said volume measurement apparatus, a measuring wheel travel detection means electrically connected to said at least one measuring wheel, and a volume measurement means electrically connected said to said measuring wheel travel detection means and to the sensors, said sensors being mapping type sensors which both emit a signal and detect a signal return reflected from an object being scanned, said signal return defining a contour of the object being scanned, said method comprising the following steps:

A. Placing said volume measurement apparatus at a starting position where one said at least one measuring wheel contacts a rolling surface;

B. Rolling said volume measurement apparatus past an object whose volume is to be measured such that the sensors will scan cross sectional areas of the object embraced within said volume measurement apparatus vertical leg and said volume measurement apparatus horizontal leg at pre-set increments;

C. Figuring only an area that all three said sensors report as solid, which is an object cross section return; and

D. Summing the products of the object cross section returns multiplied by said increment.

11. A volume measurement apparatus comprising a vertical leg attached to a horizontal leg, and at least three sensors mounted to said legs, said sensors being electrically connected to a volume measurement means, said sensors being mapping type sensors which both emit a signal and detect a signal return reflected from an object being scanned, said signal return defining a contour of the object being scanned, a first said sensor being disposed at an extreme of said vertical leg opposite said horizontal leg, a second said sensor being disposed at an extreme of said horizontal leg opposite said vertical leg, and a third said sensor being disposed at an intersection of said vertical leg and said horizontal leg.

12. The volume measurement apparatus of claim 11 further comprising at least one measuring wheel rotatably attached to said volume measurement apparatus, a measuring wheel travel detection means electrically connected to said at least one measuring wheel and to said volume measurement means, and a method of use comprising the following steps:

A. Placing said volume measurement apparatus at a starting position where one said at least one measuring wheel contacts a rolling surface;

B. Rolling said volume measurement apparatus past an object whose volume is to be measured, such that the sensors will scan cross sectional areas of the object embraced within said volume measurement apparatus vertical leg and said volume measurement apparatus horizontal leg at pre-set increments;

C. Figuring only an area that said sensors report as solid, which is an object cross section return; and

D. Summing products of the object cross section returns multiplied by said increment.

13. The method of measuring volume of claim 12 further comprising the intermediate steps of:

A1. Resetting said volume measurement apparatus to indicate zero volume measured; and

A2. Initiating a volume measurement function of said volume measurement apparatus.
