  • Patent number: 8929736
    Abstract: The method of placing regenerators along a trail connecting a source network node with a destination network node of an automatically switched optical network first identifies N tentative regeneration sites and n+1 optical paths along the trail. Wavelengths are assigned to each optical path, and the performance of the trail is assessed based on regenerator placement data and wavelength assignment data.
    Type: Grant

  • Patent number: 8571415
    Abstract: The method of placing regenerators along a trail connecting a source network node with a destination network node of an automatically switched optical network first identifies N tentative regeneration sites and n+1 optical paths along the trail. Wavelengths are assigned to each optical path; and the performance of the trail is assessed based on regenerator placement data and wavelength assignment data. The data identifying this regenerator path, namely regenerator placement data, the wavelength assignment data and the performance parameter of the trail are stored in a list, if the performance parameter is over a threshold. Selection of the tentative sites is revised whenever the initial placement fails due to a reach problem, a wavelength-blocking problem or a path quality problem. If the time for revising the initial placement, or the cost of a regenerator path is unacceptable, the regenerator path is abandoned and a further placement is initiated.

  • Patent number: 8378798
    Abstract: Method and apparatus for displaying a view of an application on a touch-sensitive display include detecting a touch on the touch-sensitive display. When the touch is at a first force, first feedback is provided and a first function is performed. When the touch is at a second force, second feedback is provided and a second function is performed. The first function and the second function are different. The first force and the second force are different.

  • Patent number: 8121652
    Abstract: A method of controlling a portable electronic device having a touch screen display includes rendering a graphical user interface including a plurality of user-selectable features on the touch screen display and, in response to detecting a touch event on the touch screen display proximal one of the user-selectable features, rendering an indicator for one of the user-selectable features corresponding to a location of the touch event prior to selection of any of the user-selectable features. The indicator is rendered intermediate ones of the user-selectable features for identifying the one of the user-selectable features absent obstruction of other ones of the user-selectable features.

  • Publication number: 20110084922
    Abstract: A method includes associating regions of a touch-sensitive display with information, detecting a touch on the touch-sensitive display, determining an area associated with the touch, and associating probability values with at least some of the information based on an area associated with the touch and the regions associated with the information.

  • Patent number: 7787769
    Abstract: The routing cycles method establishes a connection between a source network node and a destination network node based on a cycles graph. For each connection request, the network identifies ‘k’ valid solution cycles on the cycles graph, taking into account any constraints imposed by the type of routing requested. Each valid solution cycle is then split into a pair of routes, which are validated against explicit constraints received with the request, if any. The performance of each pair is then estimated and the pairs are ordered in a list based on their performance. The pair ordering is carried out based on the cost of the routes and on the chance of a successful set-up, which is given by an estimated Q factor. The network attempts to set up the connection according to the class of service for the respective request, first along the best route(s) from the list. Failing this, it will try the second best route(s), etc.

  • Publication number: 20100083108
    Abstract: A touch-screen device has a processor operatively coupled to a memory for storing and executing an application, and a touch-sensitive display screen for receiving a touch input for triggering a displaying of an escape key on the display screen. The displaying of the escape key can be triggered by touching the screen for a predetermined period of time, by swiping a stylus over the screen or by any other recognizable gesture. This soft escape key can thus be used to close, or escape from, an application.
