  • System, apparatus, and method for monitoring a subsea flow device
    Patent number: 9004174
    Abstract: A system, apparatus, and method are provided for monitoring a subsea flow device such as a subsea flowline. The apparatus generally includes a thermoelectric device that is adapted to generate electric power from a thermal potential between the subsea flow device and the surrounding seawater. A sensor that is powered by the thermoelectric device is adapted to monitor one or more characteristics of the flow device, such as temperature or strain, and provide a radiation output that is indicative of the characteristic.

  • Coupled mode arrayed waveguide grating
    Publication number: 20060222294
    Abstract: An AWG device includes a plurality of arrayed waveguides positioned close to each other. An input signal excites one of these coupled waveguides and the power is then transferred to all of the arrayed waveguides so there are enough degrees of freedom in the device to achieve any desired distribution.
