| 20080240325 | High-Speed Receiver Architecture - A receiver (e.g., for a 10 G fiber communications link) includes an interleaved ADC coupled to a multi-channel equalizer that can provide different equalization for different ADC channels within the interleaved ADC. That is, the multi-channel equalizer can compensate for channel-dependent impairments. In one approach, the multi-channel equalizer is a feedforward equalizer (FFE) coupled to a Viterbi decoder, for example a sliding block Viterbi decoder (SBVD); and the FFE and/or the channel estimator for the Viterbi decoder are adapted using the LMS algorithm. | 10-02-2008 |
| 20090060018 | Transmit Equalizer For Dispersive Channels - An equalizer at the transmitter reduces data-dependent jitter introduced by a non-linear device in the transmitter. In one implementation, the equalizer is T/2-spaced. In an alternate implementation, it is T-spaced. | 03-05-2009 |
| 20090185613 | High-Speed Receiver Architecture - A receiver (e.g., for a 10 G fiber communications link) includes an interleaved ADC coupled to a multi-channel equalizer that can provide different equalization for different ADC channels within the interleaved ADC. That is, the multi-channel equalizer can compensate for channel-dependent impairments. In one approach, the multi-channel equalizer is a feedforward equalizer (FFE) coupled to a Viterbi decoder, for example a sliding block Viterbi decoder (SBVD); and the FFE and/or the channel estimator for the Viterbi decoder are adapted using the LMS algorithm. | 07-23-2009 |
| 20110058596 | Multi-Channel Equalization to Compensate for Impairments Introduced by Interleaved Devices - A system includes a time-interleaved device. An equalizer effectively can apply different equalization to different interleaved channels. For convenience, these equalizers will be referred to as multi-channel equalizers. In one aspect, an apparatus includes an interleaved device having M interleaved channels, and a multi-channel equalizer coupled to the interleaved device. The multi-channel equalizer is capable of applying a different equalization to different interleaved channels, thus compensating for channel-dependent impairments. | 03-10-2011 |

| 20080229236 | Non-linear navigation in discussion forums - Systems, methods, and other embodiments associated with providing non-linear navigation in a discussion forum are described. One method embodiment includes maintaining a location data that identifies a thread or message to which a user has navigated. The method also includes manipulating a navigation control in a graphical user interface based on actions taken by the user and/or other users of the system. The navigation control facilitates a user moving to points not traditionally reachable in a single vertical navigation step in a discussion forum interface. | 09-18-2008 |
| 20100161645 | Change management - Systems, methods, and other embodiments associated with artifact type neutral change management are described. One example method includes maintaining an access table for each artifact in a collaborative software environment that records a most recent access of an artifact on a per user basis. An artifact type registration table is also maintained that maps each artifact type to the access table that records access information for artifacts of the given type and to a data store that stores artifacts of that type. For a given user, artifact pair, queries on the type registration table, access table, and data store are generated to return the last modification time for the artifact and the user's last access time for the artifact. This information is used to determine a change status of the artifact for the given user. This common framework can be used for artifacts of any type that are registered in the type registration table. | 06-24-2010 |
| 20100169306 | Type neutral container - Systems, methods, and other embodiments associated with an artifact type neutral container are described. This artifact type neutral container is achieved through an artifact type neutral architecture that is managed using a central type neutral registration mechanism. Queries are executed on type neutral registration tables to return data stores that store the artifacts found within a given artifact type neutral container. The data stores are queried to return the artifacts in the artifact type neutral container. The artifact type neutral container can be used in systems in which the artifact type neutral container and artifact data are stored in the same database as well as in systems in which the artifact type neutral container and artifact data are stored in different databases. | 07-01-2010 |
| 20100217804 | Collaborative draft forum-messages - Systems, methods, and other embodiments associated with collaborative draft forum-messages are described. One example method includes receiving draft forum-message data from a drafter. The draft forum-message data may identify a set of entities to whom the drafter seeks to grant edit privileges. The example method may also include providing a portion of the draft forum-message data to one of the identified entities and allowing them to view and/or modify the draft forum-message data. | 08-26-2010 |
