20120144333 | RENDER TRANSFORM BASED SCROLLING AND PANNING FOR SMOOTH EFFECTS - An information display system is described herein that separates rendering of information from receiving that information so that the rendering portion can be quickly displayed to the user and the data can arrive as it is available to provide further detail. The rendering portion creates a hardware surface measured to fill the area to be consumed by the list box or other control. Independently, the information retrieval portion queries information from a server or other source and processes the information as it is received. The system can then perform a transformation on the previously created hardware surface to insert the information in the rendered control without re-laying out the entire control or recreating user interface elements. Moving a surface is a cheaper operation for a CPU and can easily be accelerated using a GPU. | 06-07-2012 |

20140285529 | VIRTUALIZED DATA PRESENTATION IN A CAROUSEL PANEL - Embodiments are directed to displaying data items in a carousel display panel and to efficiently presenting virtualized data in a carousel display panel. In one example, a computer system accesses a list of data items that include at least a first data item and a last data item which are to be displayed in a carousel display panel. The computer system displays the selected portion of data items in the carousel display panel and receives a user input indicating that the last data item in the list is to be displayed in the carousel display panel. The computer system then rotates the data items displayed in the carousel display panel to the last data item. The last data item is thus displayed, along with at least a portion of a second-to-last data item and the first data item in the list. | 09-25-2014 |

20150192436 | OPTICAL SENSOR AND METHOD OF USE - An interferometer apparatus for an optical fibre system and method of use is described. The interferometer comprises an optical coupler and optical fibres which define first and second optical paths. Light propagating in the first and second optical paths is reflected back to the optical coupler to generate an interference signal. First, second and third interference signal components are directed towards respective first, second and third photodetectors. The third photodetector is connected to the coupler via a non-reciprocal optical device and is configured to measure the intensity of the third interference signal component directed back towards the input fibre. Methods of use in applications to monitoring acoustic perturbations and a calibration method are described. | 07-09-2015 |

20120060615 | METHOD AND APPARATUS FOR OPTICAL SENSING - The present invention provides novel apparatus and methods for fast quantitative measurement of perturbation of optical fields transmitted, reflected and/or scattered along a length of an optical fibre. The present invention can be used for point sensors as well as distributed sensors or the combination of both. In particular this technique can be applied to distributed sensors while extending dramatically the speed and sensitivity to allow the detection of acoustic perturbations anywhere along a length of an optical fibre while achieving fine spatial resolution. The present invention offers unique advantages in a broad range of acoustic sensing and imaging applications. Typical uses are for monitoring oil and gas wells such as for distributed flow metering and/or imaging, seismic imaging, monitoring long cables and pipelines, imaging within large vessel as well as for security applications. | 03-15-2012 |

20080297772 | Detecting a Disturbance in the Propagation of Light in an Optical Waveguide - An optical time domain reflectometry apparatus has a laser and light modulator for producing coherent light pulses, each having two sections of higher intensity separated by a gap of lower or substantially zero intensity. As the light pulses propagate along the optical fibre, light is continuously Rayleigh backscattered by inhomogeneities of the optical fibre. A photodetector generates backscatter signals representing the intensity of light Rayleigh backscattered in the optical fibre as each light pulse travels along the optical fibre. The PC uses these backscatter signals to derive a difference signal representing a change dI in intensity between signals generated from two successive pulses. The PC then calculates the Root Mean Square (RMS) of the difference signal averaged over the interval between the two sections of the light pulses. Next, the PC averages the backscatter signal generated from the first of the pulses over the same interval and normalises the RMS difference signal using the averaged signal to obtain a compensated difference signal that depends only on differences in the rate of change of phase of light of the light pulses as they travelled along the waveguide. This is repeated at different wavelengths to allow the compensated difference signal to be adjusted to represent the magnitude of the differences. | 12-04-2008 |

20110199607 | DETECTING A DISTURBANCE IN THE PHASE OF LIGHT PROPAGATING IN AN OPTICAL WAVEGUIDE - A partially coherent Optical Time Domain Reflectometry (OTDR) apparatus has a light source comprising a directly modulated semiconductor Distributed FeedBack (DFB) laser diode for transmitting partially coherent light pulses along a monomode optical fibre. Light Rayleigh backscattered from the light pulses as they travel along the optical fibre is output from the end of the fibre into which the light pulses are transmitted to a Fibre Bragg Grating (FBG) filter. The FBG filter reduces the supectral width of light received at a photodetector. In one embodiment, the supectral width of the FBG filter is around one fifth of the supectral width of the light pulse after it has travelled around 1 km along the optical fibre. As a consequence of reducing the supectral width of the light received at the photodetector, the FBG filter increases the temporal coherence of the light. So, the FBG filter can ensure that the detected light is sufficiently coherent that a temporal supeckle pattern can be detected at the photodetector. At the same time, the light traveling in the optical fibre can be relatively supectrally broad so that non-linear effects in the optical fibre, such as Brillouin scattering, can be reduced. | 08-18-2011 |
