  • Patent number: 10337867
    Abstract: An apparatus includes a symmetrical wavelength multiplexor (SWM) that includes a first port that receives a depolarized beam of light of a first center wavelength for a first wavelength range. A second port of the SWM receives a second center wavelength of light for a second wavelength range that is greater than the first wavelength range. A third port of the SWM provides a substantially symmetrical wavelength output to drive a fiber optic gyroscope (FOG) in accordance with the second center wavelength. The depolarized beam of light of the first center wavelength travels from the first port to the second port of the SWM and light of the second center wavelength travels from the second port to the third port of the SWM. The SWM mitigates spectral asymmetries between orthogonal axes of the second wavelength.

  • Patent number: 8124661
    Abstract: A plurality of voids are introduced into a polymeric material. One or more stress sensitive components in abutment with a portion of the polymeric material are buffered from one or more stresses through employment of the portion of the polymeric material that comprises one or more voids of the plurality of voids. A movement of the portion of the polymeric material is accommodated through compression of one or more of the one or more voids.

  • Patent number: 6980709
    Abstract: In one example, the voids 208 comprise one or more gas (e.g., air) bubbles in the solid material 206. In another example, the voids 208 comprise a structure that preserves a space in the solid material 206. In a further example, the voids 208 comprise hollow elastomeric bubbles, for example, hollow elastomeric microspheres. The hollow elastomeric microspheres comprise microballoons with tin walls that encapsulate a gas to allow for easy compression. For example, the walls of the hollow elastomeric microspheres are strong enough to avoid breakage under pressure, but thin enough to easily compress. In a further example, once cured in the solid material 206, the hollow elastomeric microspheres comprise substantially similar compressibility characteristics as gas bubbles. The voids 208 in one example are added to a resin of the solid material 206 in a substantially uniform distribution. For example, the hollow elastomeric microspheres are stirred into the resin of the solid material 206.

  • Patent number: 6898364
    Abstract: An apparatus in one example comprises a buffer layer located on a face that serves as a primary support for an optical fiber winding along a first general direction. The face is coupled with a body that serves as a primary support for the optical fiber winding along a second general direction. The optical fiber winding comprises an optical fiber wound about the body. The buffer layer serves to promote a decrease of one or more strain gradients among a plurality of portions of the optical fiber winding.

  • Publication number: 20050008279
    Abstract: A polymeric material of an apparatus in one example abuts one or more sensor fibers. The polymeric material comprises a plurality of voids. Upon an introduction of an applied force to a portion of the polymeric material, one or more of the plurality of voids compress to allow the portion of the polymeric material to absorb a portion of the applied force and promote a decrease of a reaction force from the portion of the polymeric material to one or more of the one or more sensor fibers.
