Abstract

Apparatus, methods and systems for obtaining one or more dimensions of an object employing, at least in part, touch sensors.

Claims

1. An object dimensioning apparatus, comprising:

at least one linear sensor strip oriented in a horizontal plane and comprising a resistive touchscreen configured to generate a signal corresponding to linear distances of any respective location only along a longitudinal axis of the at least one linear sensor strip with respect to a reference location responsive to touch of the at least one linear sensor strip at a respective location; and

a back surface above the reference location of at least one associated linear sensor strip, extending perpendicular to a plane of the at least one associated linear sensor strip.

2. The object dimensioning apparatus of claim 1, wherein the at least one linear sensor strip comprises two linear sensor strips located in substantially coplanar relationship and oriented at a mutually included angle of 90°

, and further comprising a back surface located above the reference location of each linear sensor strip and extending transverse to a longitudinal axis of that linear sensor strip.

3. The object dimensioning apparatus of claim 2, wherein an end of one of the two linear sensor strips proximate the reference location thereof overlaps an end of the other of the two linear sensor strips proximate the reference location thereof.

4. The object dimensioning apparatus of claim 2, wherein the back surfaces meet and form a corner.

5. The object dimensioning apparatus of claim 2, further comprising a third linear sensor strip oriented perpendicular to the two linear sensor strips and substantially coplanar with one of the two back surfaces.

6. The object dimensioning apparatus of claim 2, further comprising one of an ultrasound distance sensor and a laser range sensor over the two linear sensor strips aimed toward and substantially perpendicular to a plane of the two linear sensor strips proximate the reference locations of each of the two linear sensor strips.

7. The object dimensioning apparatus of claim 1, wherein the at least one linear sensor strip comprises two linear sensor strips located in substantially coplanar, mutually parallel and laterally offset relationship and the back surface is above a distal end of one of the two linear sensor strips and oriented transverse to a longitudinal axis thereof.

8. The object dimensioning apparatus of claim 7, wherein mutually proximate ends of the two linear sensor strips overlap longitudinally.

9. The object dimensioning apparatus of claim 1, further comprising a microprocessor having memory associated therewith and operably coupled to the at least one linear sensor strip, and an input device and an output device operably coupled to the microprocessor.

10. The object dimensioning apparatus of claim 9, wherein the output device comprises at least one of a display and a network interface.

11. The object dimensioning apparatus of claim 1, further comprising a scale positioned for weighing an object resting on the at least one linear sensor strip.

12. An object dimensioning apparatus, comprising:

a capacitive touchscreen sensor element with slider capability and configured to generate an outline of an object resting upon the sensor element responsive to a continuous touch about a periphery of the object.

13. The object dimensioning apparatus of claim 12, further comprising one of an ultrasound distance sensor and a laser range sensor over the capacitive touchscreen sensor element aimed toward and substantially perpendicular to a plane of the capacitive touchscreen sensor element.

14. The object dimensioning apparatus of claim 12, further comprising a linear sensor element oriented perpendicular to the capacitive touchscreen sensor element.

15. A method of determining at least one dimension of an object, comprising:

placing an object on at least one linear sensor strip oriented in a horizontal plane and comprising a resistive touchscreen configured to, responsive to touch, generate a signal corresponding to a linear distance of any respective location only along a longitudinal axis of the at least one linear sensor strip with respect to a reference location responsive to touch of the at least one linear sensor strip at a respective location;

placing an object on the at least one linear sensor strip with a side thereof adjacent the reference location;

touching the at least one linear sensor strip on at least one location thereon adjacent another side of the object opposite the side to generate a signal; and

determining, responsive to the signal and using a processor, a linear distance of the at least one location with respect to the reference location, the linear distance corresponding to a dimension of the object between the side and the another side thereof.

16. A method of determining at least one dimension of an object, comprising:

placing an object on a capacitive touchscreen sensor element with slider capability and configured to generate a signal representative of an outline of an object resting upon the sensor element responsive to a substantially continuous touch about a periphery of the object;

touching the sensor element substantially continuous about a periphery of the object; and

determining, responsive to the signal and using a processor, at least one dimension of the object.
