Abstract: A sensing assembly including a fiber for monitoring at least one condition or parameter and a strip formed from a pair of laminae disposed with the fiber. The laminae are arranged parallel to each other and engaged longitudinally along the fiber for enabling the strip to secure the fiber in place. A method of monitoring a parameter or condition with a sensing assembly is also included.

Abstract: A method of manufacturing an optical fiber includes: disposing an axially extending preform structure on a support structure; directing a gas mixture along a major axis of the preform structure in a first axial direction; disposing a heating device proximate to the preform structure; and activating the heating device and moving the heating device along the major axis in a second axial direction to heat the preform structure and deposit at least one layer of material on the preform structure, the second axial direction being opposite to the first axial direction.

Abstract: A method and apparatus for controlling the shape and position of a deformable object are described. At least a portion of an object is heated to a temperature sufficient to render the heated portion deformable by a force. An image profile of the heated portion of the object is obtained. A controller compares the image profile to a reference profile and produces an error image signal. Based on the error image signal, an instruction signal is generated. A force applicator responsive to the instruction signal applies a radial force to at least one distinct predetermined location on the heated portion of the object in response to the instruction signal to cause the heated portion of the object to conform to the reference profile. The invention is particularly useful in controlling the shape of an optical fiber preform.
