  • Patent number: 8547539
    Abstract: A system and method for detecting breakage, rupture or malfunctioning of a pipe or cable structure, including sensing elements for monitoring the structure and placed in, on or around the structure for monitoring the breakage, rupture or malfunctioning of the structure. The sensing elements provide sensing data regarding events related to breakage, rupture or malfunctioning and are placed near the structure so as to perform a breakage, rupture or malfunction detection function, and within a distance sufficient to obtain a measureable strain, tension, torsion, vibration, acceleration, and/or temperature response signal based on the breakage, rupture or malfunctioning of the structure. One of the sensing elements is based on Coherent Rayleigh Noise (CRN) sensing techniques, and the system is configured to interpret the sensed data for determining the breakage, rupture or malfunctioning of the structure.

  • Patent number: 8408064
    Abstract: A distributed acoustic wave detection system and method is provided. The system may include a fiber optic cable deployed in a well and configured to react to pressure changes resulting from a propagating acoustic wave and an optical source configured to launch interrogating pulses into the fiber optic cable. In addition, the system may include a receiver configured to detect coherent Rayleigh noise produced in response to the interrogating pulses. The CRN signal may be use to track the propagation of the acoustic wave in the well.

  • Publication number: 20050229451
    Abstract: This invention relates to outdoor advertising and, more particularly, to methods, systems and apparatus for providing branded parking spaces. The invention includes using a standard parking space as an advertising space that creates an opportunity for advertisers to reach customers with branded messages at a place where they park a vehicle, creating an out-of-home advertising venue. The parking space can have an advertising message applied to it, such as on a sign placed within the parking space, adjacent to the parking space or in an area between two adjacent parking spaces. The advertising message can also be applied to the asphalt or concrete within the parking space, adjacent to the parking space or in an area between two adjacent parking spaces. The advertising message can also be applied to a canopy, overhang or ceiling that is within the parking space, adjacent to the parking space or in an area between two adjacent parking spaces.
