Abstract: An optical fiber strain sensor array comprises several sensor support panels spaced in its longitudinal direction and at least one connecting member extending in the longitudinal direction, which mechanically interconnects the sensor support panels. An optical fiber is supported by the sensor support panels and the connecting member. The optical fiber extends with the connecting member between the sensor support panels and forms a curve on the sensor support panel, the curve including at least one portion of the optical fiber that extends in the transverse direction. The width of the connecting member is substantially less than the width of the sensor support panels, such that the connecting member is capable of flexure in the transverse direction. This has the advantage that the connecting member can be flexed to take up any slack during installation of the optical fiber strain sensor array in a wind turbine blade and can be fitted to the turbine blade even if the blade has a conical shape.

Abstract: A mobile terminal that operates in a plurality of position tracking modes. The mobile terminal comprises a Global Positioning System (GPS) unit for receiving GPS signals from a plurality of GPS satellites. The GPS unit can operate in i) a device autonomous fix (DAF) mode, ii) a server-computed assisted fix (SCAF) mode, and iii) a device-computed assisted fix (DCAF) mode. The mobile station also comprises a network transceiver for communicating with at least one terrestrial wireless network and a controller for controlling the operating mode of the GPS unit. The controller transitions the GPS unit between the DAF mode, the SCAF mode, and the DCAF mode. The controller receives an interrupt signal from at least one sensor and, in response, causes the GPS unit to operate in one of the DAF mode, the SCAF mode, and the DCAF mode.

Abstract: A mobile terminal capable of operating in a plurality of position tracking modes. The mobile terminal comprises: 1) a Global Positioning System (GPS) unit capable of receiving GPS signals from a plurality of GPS satellites, wherein the GPS unit is further capable of operating in i) a device autonomous fix (DAF) mode, ii) a server-computed assisted fix (SCAF) mode, and iii) a device-computed assisted fix (DCAF) mode. The mobile terminal also comprises: 2) a network transceiver capable of communicating with at least one terrestrial wireless network; and 3) a controller capable of controlling the operating mode of the GPS unit. The controller is capable of transitioning the GPS unit between the DAF mode, the SCAF mode, and the DCAF mode.
