20130272656 | Double-Sided Compression-Tuned Fiber Bragg Grating - A new type of tunable fiber Bragg grating (FBG) is proposed based on the compression of FBG from both sides. In this technique, the FBG is compressed from both sides simultaneously which provides the more uniform force distribution along the grating compared to the compression from one side. As a result, the grating period changes uniformly due to compression and the same spectral shape can be achieved over a wide spectrum. The double-sided compression technique represents a significant improvement over the prior wavelength tunable fiber grating techniques, especially for the long gratings. | 10-17-2013 |
20140123764 | Fiber Bragg Grating Pressure Sensor with Adjustable Sensitivity - A new type of optical pressure sensor with adjustable sensitivity is proposed based on the fiber Bragg grating (FBG). In this technique, the pressure changes the length of a metal bellows which is placed behind a spring. The fiber grating is fixed over the bellows between a fixed position and the connection point of bellows and spring. The wavelength change of FBG is caused by the change in the bellows length; however, the spring controls the total length expansion of the bellows. It will bring two benefits: first it is easy to change the pressure sensing range by changing the spring rate; and secondly the spring improves the linearity of the wavelength sift due to the pressure. The FBG is installed outside of the bellows and is not in contact with the material in which the pressure should be measured (gas or liquid) in contrast with other pressure sensors where the FBG is inside the bellows. This is an important issue because some materials could damage or change the characteristics of the fiber over the time. | 05-08-2014 |

Based on the load index, each meter can generate and send its response to the server and the server will be able to process its response. | 07-02-2015 |
20150212122 | SYSTEM AND METHOD FOR A POWER METER TO COMMUNICATE THROUGH A POWER LINE - The disclosure relates to a meter for monitoring usage of power provided by a power transmission system to a site and a related method. The meter comprises: a meter module connected to a power feed associated with the transmission system to provide readings relating to the power; a connection to a household AC power supply providing power to the meter; a rectifier circuit connected to the AC power to generate a DC power signal; a voltage detection circuit to detect a low voltage condition where an output from the rectifier circuit drops below an operational threshold for the meter and to generate a low voltage signal upon detection of same; and a message generation module for receiving the low voltage signal and for generating a power loss message for transmission carried on a message carrier having on a carrier having frequency between approximately 2 MHz and 30 MHz. | 07-30-2015 |

20130098806 | BITUMEN FROTH TREATMENT SETTLER FEED DISTRIBUTOR - A feed distributor for a settler is provided, the settler effective for separating a solvent-diluted bitumen froth into a water/solids stream and a hydrocarbon stream, the feed distributor comprising: an inlet conduit effective to route bitumen froth into the settler; and an essentially horizontal plate attached to a lower extremity of the inlet conduit and wherein the inlet conduit defines openings through which the solvent-diluted bitumen froth can pass from inside the inlet conduit to a volume above the essentially horizontal plate. | 04-25-2013 |
20140216985 | CLOSED LOOP SOLVENT EXTRACTION PROCESS FOR OIL SANDS - The present invention is directed to a method which includes the steps of: contacting an oil sand with a suitable solvent to generate a solvated oil sand slurry; separating solvent-diluted bitumen from the solvated oil sand slurry to generate (a) a solvent-diluted bitumen and (b) a slurry with increased solids concentration; filtering the slurry with increased solids concentration; dropping the solids into a pressure reduction vessel wherein the pressure in the pressure reduction vessel is a pressure below a vapor pressure of the solvent; and drying the solids removed from the pressure reduction vessel to produce solids having dry tailings. The method of the present invention may be used to produce a low ash bitumen product and dry tailings from oil sands. | 08-07-2014 |
