| Number | Title | Issue Date |
| 7729252 | Methods and devices for providing fast and robust overload control Techniques are provided for controlling overload conditions using two values; an acceptance rate fraction allowed value and an occupancy fraction allowed value. The inventive techniques allow quick response to the sudden onset of overload conditions, are robust enou... | 06/01/2010 |
| 7707451 | Methods and devices for recovering from initialization failures The time it takes to recover from a system initialization failure may be reduced by determining whether to enable a recovery process immediately, or defer such a process. Sometimes it is desirable to defer a recovery process until certain interdependencies between s... | 04/27/2010 |
| 7706383 | Minimum contention distributed wavelength assignment in optical transport networks An optical transport network comprises a number of nodes, or routers, which are coupled together via optical fibers. When a physical link comes up between a node and a neighboring node, a handshake between the node and the neighboring node recognizes the link such t... | 04/27/2010 |
| 7701909 | Methods and devices for selecting sets of available sub-channels Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for trans... | 04/20/2010 |
| 7698617 | Intelligent switch and method for retransmitting a lost packet to decoder(s) An intelligent switch and method are described herein which help to effectively retransmit a lost packet that is associated with a television broadcast stream to one or more set-top boxes. ... | 04/13/2010 |
| 7697547 | Internet protocol video delivery in passive optical networks Data representing video content is distributed over a passive optical network (PON) on virtual channels that are assigned to television (TV) channels as subscribers request the TV channels and de-assigned from TV channels when subscribers are no longer viewing them.... | 04/13/2010 |
| 7697417 | Methods and devices for re-routing MPLS traffic Multi-Protocol Label Switched (MPLS) traffic is re-routed to an alternate, Label Switched Path (LSP) to bypass a failure along a primary LSP, even though the failure occurs at or along an ingress section of an LSP, while associating an original IP address to the alt... | 04/13/2010 |
| 6867728 | Methods and systems for identifying signals-of-interest Signals-of-interest are identified by distinguishing such signals from signals constituting environmental or internal receiver noise. A received signal is rapidly sampled in order to set a dynamic, system threshold. Signals above the threshold constitute signals-of-... | 03/15/2005 |
| 6603846 | Methods and devices for selecting preferred call back numbers using CID data A telephone or similar device/system may be equipped or used to select preferred call back numbers. These preferred numbers may be programmed into a device by a user. When an incoming call comprising caller identity ("CID") data is received, preferred cal... | 08/05/2003 |
