Abstract: A method of manufacturing suspension seating includes providing a blank to be used in a suspension member. The blank has a non-visible marker. The method also includes illuminating the non-visible marker with an excitation source. The non-visible marker becomes detectable when illuminated by the excitation source. The method further includes sensing the non-visible marker with a sensor. The sensor is configured to detect the non-visible marker when illuminated by the excitation source. The method also includes determining, by a controller, a characteristic of the blank using the non-visible marker. The controller is in communication with the sensor and configured to receive information related to the non-visible marker from the sensor. The method further includes adjusting the blank to achieve the desired characteristic.

Abstract: A method of inspecting a structure including a photonic material using a movable inspection apparatus includes irradiating a section of the structure, receiving radiation diffracted from a photonic material in the section of the structure, determining a deformation of the photonic material as a function of at least one of i) an intensity of the radiation received ii) a position of the radiation received and iii) a wavelength of the radiation received, and determining if a magnitude of the deformation is higher than a threshold. If the magnitude of the deformation is higher than the threshold data is stored concerning the deformation of the photonic material; contrarily, if the magnitude of the deformation is not higher than the threshold: the inspection at the location of the photonic material is stopped and the inspection apparatus is moved in order to inspect another section of the structure.

Abstract: A system and method measuring subterranean stress. The system and method includes a non-destructive sheath enveloping a tubular structure positioned in direct contact with a lateral subterranean rock formation for sensing expansive changes in the subterranean rock formation. A fiber optic is directly embedded in the non-destructive sheath positioned adjacent to the exterior surface of the tubular structure. The fiber optic transmits light and thereafter receives light in proportion to the expansive changes in the subterranean rock formation. A spectrometer connected to the fiber optic remote from the non-destructive sheath. The spectrometer measures hydrostatic stress in the subterranean rock formation without estimating acoustoelastic effects or occluding the tubular structure.

Abstract: A method for analyzing stress in an object according to spectrum data is provided. The spectrum data is obtained from an interference fringe pattern of the object that results from performing photoelasticity. The method includes: analyzing the spectrum data to obtain three sets of intensity data related respectively to different wavelengths of light used in photoelasticity; calculating wrapped phases according to the three sets of intensity data, respectively; calculating preliminary stress values according to the wrapped phases, respectively; determining a system of stress equations according to a relation among the preliminary stress values; and calculating an estimated stress value using the system of stress equations.

Abstract: A system and method measures subterranean stress. The system and method includes a cement mixture that is mixed with water to set as a solid and a stress measuring-medium having piezospectroscopic properties that directly reveals stress in situ within the cement mixture in response to a photo stimulation. The stress measuring-medium combines with the cement mixture as a dry blend before being combined with water.
