Moreover, a time during which a signal from the first clock domain is unchanging is determined such that the signal is capable of being safely sampled by a second clock domain, using the phase estimate."

The co-inventors are Bojan Vrcelj, San Diego, Raghuraman Krishnamoorthi, San Diego, Seong Taek Chung, Redwood City, Calif., and Fuyun Ling, San Diego. The abstract of the patent published by the U.S. Patent and Trademark Office states: "A frequency tracking method and apparatus is provided. A receiver receives OFDM symbols and determines associated frequency offset. A frequency error estimator selects a cross correlation window for determining frequency offset based on timing offset. A symbol timing estimator is used to determine the timing offset." The patent application was filed on March 15, 2006 (11/376,986).

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A modified Ethernet packet includes a MAC address unlearn flag. A port receiving the packet unlearns the specified MAC address, i.e., removes the corresponding entry from its forwarding table. Unlearn packets may be generated by a switch CPU in response to detection of a port failure in order to remove entries associated with the failed port. The modified Ethernet packet may alternatively, or also, include an attribute learn field. An Ethernet switch is operable to learn the specified attribute in response to receipt of the packet. Attributes that may be specified include: copy-to-CPU; static; class-of-service; source-discard; destination-discard; and L3. The copy-to-CPU attribute is operable to prompt copying of subsequent packets observed with the same SA to the CPU. The static attribute is operable to prompt prevention of a specified MAC address from being removed from a forwarding table due to aging. The class-of-service attribute is operable to prompt override of a packet class-of-service value with a specified value for subsequent packets of a specified MAC address. The source-discard attribute is operable to prompt discard of subsequent packets having a specified SA. The destination-discard attribute is operable to prompt discard of subsequent packets having a specified DA. The L3 attribute is operable to prompt packets destined for a specified MAC address to be routed rather than switched." The patent application was filed on March 20, 2006 (11/384,883).

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A circuit includes a first wireless interface circuit that transceives packetized data with a first external device in accordance with a first wireless communication protocol. A second wireless interface circuit transceives packetized data with a second external device in accordance with a second wireless communication protocol and wherein the operation of the second wireless interface circuit interferes with the operation of the first wireless interface circuit. A processing module selectively preempts use of the second frequency spectrum by the second external device using a plurality of preemption modes including a first preemption mode and a second preemption mode." The patent application was filed on May 10, 2007 (11/801,644).
