A system and method for processing wake-up signals during a sleep mode of a computer in a communications network to wake up sleeping components of the computer. The system includes an extended PHY (physical layer) device for receiving wake-up signals from a network medium, converting the wake-up signals into an additionally-encoded data packet, and generating a standardized wake-up packet based on the additionally-encoded data packet. The system also includes a MAC (media access controller) device, coupled to the extended PHY device, for receiving the standardized wake-up packet and generating a wake-up notification signal in response to the standardized wake-up packet to wake up the sleeping to components of the computer.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
