  • Patent number: 10257079
    Abstract: A network node that provides egress fault protection for a primary egress node. The network node may receive a service label associated with an application from a primary egress node of a primary label switched path (LSP).

  • Publication number: 20190103930
    Abstract: A wireless communication device includes one or more transmitter (TX)-receiver (RX) pairs, one or more RX distortion estimators, and a combiner. A first RX distortion estimator receives a first TX signal corresponding to a first TX of the first TX-RX pair and a second TX signal corresponding to a second TX of a second TX-RX pair. The first RX distortion estimator processes the first TX signal and the second TX signal based on a first base function set including at least one base function to generate a first distortion signal set including at least one distortion signal. Then, the first RX distortion estimator processes the first distortion signal set to generate a first RX correction signal. The wireless communication device's combiner generates a first distortion compensated RX signal by compensating for distortion in a first RX signal of the first TX-RX pair based on the first RX correction signal.

  • Patent number: 10248180
    Abstract: A processing system includes multiple processors in which a first processor operates at a first clock frequency and first supply voltage at all times. At least one processor is dynamically switchable to operate at the first clock frequency and first supply voltage resulting in the first and second processors providing symmetrical multi-processing (SMP) or at a second clock frequency and a second supply voltage resulting in the first and second processors providing asymmetrical multi-processing (ASMP). An integrated controller (e.g., finite state-machine (FSM)) controls not only voltage change, but also clock-switching. Various criteria can be used to determine when to switch the at least one switchable processor to improve power consumption and/or performance. Upon receipt of a switching command to switch between SMP and ASMP, a series or sequence of actions are performed to control a voltage supply and CPU/memory clock to the switchable processor and cache memory.
