  • Patent number: 9279666
    Abstract: A system is provided for monitoring strain in a substrate using a strain sensor element within a fiber optic sensing cable. Accurate and rapid measurement of strain of remote substrates presents major technical challenges and is the focus of much of the description presented. However, systems, methods and devices provided by the present invention are not only capable of reliably measuring strain in real time, but are also capable of measuring other characteristics of a substrate such as its temperature, pressure and its acoustic characteristics. The system is configured such that a strain sensor element within a strain sensing zone detects substantially the true strain characteristics of the substrate. And while other sensing elements within the same fiber optic sensing cable may not be configured to detect substrate strain at all, these sensing elements may reliably measure the temperature and pressure at the surface of the substrate adjacent to the strain sensing zone.

  • Patent number: 9212722
    Abstract: A vibration reduction apparatus includes an actuator applying a force to a beam supporting a cabin so as to bend the beam, an acceleration sensor measuring the acceleration of the cabin, and a controller controlling the actuator based on the measured acceleration. When a vibration containing a plurality of vibration components is transmitted to the cabin via the beam, the vibration reduction apparatus thus structured reduces the vibration more certainly by applying a bending load to the beam so that the bending load caused by the vibration is cancelled. This provides damping of the cabin more certainly.

  • Patent number: 9176015
    Abstract: A point load sensor measures compressive forces exerted on the outside of a ring in diametric compression irrespective of the direction of application of the force. The sensor consists of a ring with strain gauges placed in a configuration to measure the circumferential strain at two positions on the ring ninety degrees apart resulting from bending of the ring as the ring is loaded in diametric compression. The two measurements are corrected and combined to recover the compressive force on the ring. A method for calibrating and resolving the compressive force does not require the angle of loading or sensor orientation as an input, thus allowing resolution irrespective of the direction of the compressive force.

  • Patent number: 9173269
    Abstract: A lighting system for accenting a region of a target surface comprising a color matching engine, a plurality of light sources, a color capture device configured to measure light reflected by a target surface, and a computerized device configured to operate the plurality of light sources to emit an analysis light so as to be incident upon the target surface and identify a region of the target surface that reflects two or more wavelength ranges of light using a pattern recognition algorithm, defining a detected pattern having wavelength ranges. The color matching engine is configured to perform a matching operation that operates to determine dominant wavelength(s) of the wavelength ranges and polychromatic lights including or excluding dominant wavelength(s). The computerized device operates the light sources to emit a combined light being sequentially each of the polychromatic lights.

  • Patent number: 9032810
    Abstract: The present invention relates to a method of sensing permanent deformation of a structure, the method comprising the steps of; determining the strain required to permanently deform a structure; securing to the structure one or more strain sensors so that a strain sensor will deform when the structure is deformed, wherein the or each strain sensor comprises one or more optical fibers and wherein the or each strain sensor is configured such that it will permanently deform only when the structure permanently deforms; carrying out distributed fiber optic analysis to sense if a strain sensor has been permanently deformed, wherein a permanent deformation of a strain sensor indicates permanent deformation of the structure. The present invention also relates to a corresponding assembly.

    Abstract: A pressure sensing pad includes a flexible planar layer having a two-dimensional sensing area, and an optical fiber embedded in the plane of the flexible planar layer traversing the two-dimensional sensing area in a particular configuration. At least one end of the fiber optic strain sensor has a connector that is connectable to an interferometric-based fiber optic interrogation and processing system. When the connector is connected to the an interferometric-based fiber optic interrogation and processing system and pressure is applied to the pressure sensing pad, a signal from the optical fiber is provided to and processed by the interferometric-based fiber optic interrogation and processing system to determine a two-dimensional pressure map for the two-dimensional sensing area.
