Patent ID: 7987611

Claim:
A measuring device that may be selectively configured between an extended condition and a collapsed condition, comprising: a first and a second elongated member, each member having a proximal end, a distal end, and a convex surface, wherein the convex surface of each member is flexible such that the members may bend about at least one bending axis of the measuring device and resilient such that the convex surfaces are biased toward their stable convex shape and the measuring device is biased toward the extended condition; a flexible housing, wherein the first and the second members are disposed within the flexible housing forming a covered pair having a proximal end and a distal end, wherein the apex of the convex surface of the first member is opposite the apex of the convex surface of the second member when the members are disposed within the flexible housing; a securing means for securing the measuring device in the collapsed condition, wherein the securing means includes at least one magnet; and a measuring means.
