Abstract

Aspects of the subject disclosure may include, for example, obtaining a first plurality of circumference measurements, each of the first plurality of circumference measurements corresponding to a first circumference around a limb of a person at a respective one of a plurality of locations of the limb, each of the first plurality of circumference measurements being obtained from a respective one of a plurality of elastic measurement elements that is positioned at a respective one of the locations; determining, based upon the first plurality of circumference measurements, a first geometric profile along a length of the limb; and outputting data representing the first geometric profile. Other embodiments are disclosed.

First claim

What is claimed is:

1. A device comprising:
a sleeve having a length that spans from a first end of the sleeve to a second end of the sleeve, the sleeve having a first non-expanded circumference at a first location along the length of the sleeve, and the sleeve having a second non-expanded circumference at a second location along the length of the sleeve;
a first elastic measurement element attached to the sleeve at the first location, the first elastic measurement element traversing a first portion of the first non-expanded circumference;
a second elastic measurement element attached to the sleeve at the second location, the second elastic measurement element traversing a second portion of the second non-expanded circumference;
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
obtaining, from the first elastic measurement element, a first value representative of a first expanded circumference of the sleeve at a point in time when the sleeve is disposed on a limb of a person;
obtaining, from the second elastic measurement element, a second value representative of a second expanded circumference of the sleeve at the point in time when the sleeve is disposed on the limb of the person;
determining, based upon the first value and the second value, a geometric profile along the limb; and
outputting, to a computing device, data representing the geometric profile, the outputting of the data to the computing device enabling the computing device to present via a display a graphic visualization of a difference between the geometric profile and another geometric profile of the limb of the person that had been determined at another point in time that is different from the point in time at which the geometric profile had been determined.

2. The device of claim 1 , wherein:
the first elastic measurement element comprises a first elastic resistive element, wherein a first expansion of the first elastic resistive element provides a first change in resistance that correlates to the first expansion of the first elastic resistive element; and
the second elastic measurement element comprises a second elastic resistive element, wherein a second expansion of the second elastic resistive element provides a second change in resistance that correlates to the second expansion of the second elastic resistive element.

3. The device of claim 1 , wherein:
the first elastic measurement element is disposed on the sleeve, the first elastic measurement element is disposed in the sleeve, or any combination thereof; and
the second elastic measurement element is disposed on the sleeve, the second elastic measurement element is disposed in the sleeve, or any combination thereof.

4. The device of claim 1 , wherein the computing device comprises the display.

5. The device of claim 1 , wherein:
the first end of the sleeve is open and the second end of the sleeve is open, such that the sleeve is in a form of a cuff or an arm band.

6. The device of claim 1 , wherein:
the first end of the sleeve is open and the second end of the sleeve is closed, such that the sleeve is in a form of a sock or a glove.

7. The device of claim 1 , wherein the difference between the geometric profile and the another geometric profile is shown as a shaded area.

8. A machine-readable storage medium comprising executable instructions that, when executed by a system including a processor, facilitate performance of operations, the operations comprising:
obtaining a first plurality of circumference measurements, each of the first plurality of circumference measurements corresponding to a respective first circumference around a limb of a person at a respective one of a plurality of locations of the limb, each of the first plurality of circumference measurements being obtained from a respective one of a plurality of elastic measurement elements that is positioned at a respective one of the locations, and each of the plurality of elastic measurement elements being attached to a sleeve that has a length;
determining, based upon the first plurality of circumference measurements, a first geometric profile along the limb;
obtaining a second plurality of circumference measurements, each of the second plurality of circumference measurements corresponding to a respective second circumference around the limb of the person at the respective one of the plurality of locations of the limb, the first plurality of circumference measurements being obtained at a first time, the second plurality of circumference measurements being obtained at a second time, and the second time being after the first time;
determining, based upon the second plurality of circumference measurements, a second geometric profile along the limb;
comparing the second geometric profile to the first geometric profile to generate difference data between the second geometric profile and the first geometric profile; and
presenting via a display a graphic visualization of the difference data, the graphic visualization showing a difference between the first geometric profile existing at the first time and the second geometric profile existing at the second time.

9. The machine-readable storage medium of claim 8 , wherein:
each of the plurality of elastic measurement elements comprises an elastic resistive element such that for a given elastic resistive element an expansion thereof provides a change in resistance that correlates to the expansion.

10. The machine-readable storage medium of claim 8 , wherein:
the first plurality of circumference measurements equals X number of measurements;
the plurality of locations equals X number of locations;
the plurality of elastic measurement elements equals X number of elastic measurement elements; and
X is an integer between 2 and 50, inclusive.

11. The machine-readable storage medium of claim 8 , wherein the system comprises the display.

12. The machine-readable storage medium of claim 8 , wherein the operations further comprise transmitting data representing the first geometric profile to a remote device.

13. The machine-readable storage medium of claim 12 , wherein the remote device comprises a database, and wherein the data representing the first geometric profile is stored in the database in association with an identity of the person.

14. The machine-readable storage medium of claim 8 , wherein each of the plurality of elastic measurement elements is disposed on the sleeve, each of the plurality of elastic measurement elements is disposed in the sleeve, or any combination thereof.

15. The machine-readable storage medium of claim 8 , wherein each of the plurality of elastic measurement elements comprises a resistance element having a first electrical resistance in an elongated state and a second electrical resistance in a non-elongated state, wherein the first electrical resistance is different from the second electrical resistance.

16. The machine-readable storage medium of claim 8 , wherein:
the first end of the sleeve is open and the second end of the sleeve is closed, such that the sleeve is in a form of a sock or a glove; or
the first end of the sleeve is open and the second end of the sleeve is open, such that the sleeve is in a form of a cuff or an arm band.

17. The machine-readable storage medium of claim 8 , wherein the difference between the first geometric profile and the second geometric profile is shown as a shaded area.
