In the event that the user wishes to see the original higher-fidelity version of an image, clicking on the image or an associated icon loads the original-fidelity version of the image, replacing the low-fidelity version. The light version of the web page loads faster than would the original version of the web page, and requires less data to be downloaded when rendering the web page. This enables a user with a data-limited connection to select how he or she wishes to “spend” their data consumption. |

System and method for optical channel reconfiguration
In wavelength division multiplexing (WDM) systems, one optical multiplexing section (OMS) can support several channels. During a network reconfiguration, the number or channel index of the channels in the OMS may change, which may result in a change in gain for other channels in the OMS due to the channel loading dependant gain properties of many optical amplifiers. Equalization is therefore required in order to reduce power excursion for the channels in the OMS.

The model predicts the change in gain for the channels in an OMS following network reconfiguration, and allows for an equalizer to quickly or pre-emptively adjust for the changes. This model may include an artificial neural network, which is trained using some of the possible channel loading conditions for the OMS. |

Semiconductor fabrication
In-situ patterning of semiconductor structures is performed using one or more “shadow walls” in conjunction with an angled deposition beam. A shadow wall protrudes outwardly from the surface of a substrate to define an adjacent shadow region in which deposition is prevented due to the shadow wall inhibiting the passage of the angled deposition beam. Hence, deposition will not occur on a surface portion of a semiconductor structure within the shadow region. Shadow walls can thus be used to achieve selective patterning of semiconductor structures. The shadow walls themselves are formed of semiconductor. In one implementation, the semiconductor structure and the one or more shadow walls used to selectively pattern it may be formed using selective area growth (SAG). |
