  • Patent number: 10708885
    Abstract: CoAP network nodes may leverage context awareness to take autonomous action to adjust network operations. Context-aware procedures may be pre-configured, established by management entities, or negotiated between nodes, and include parameters for the monitoring and evaluation of data, as well has triggers for taking action. By monitoring requests to observe a resource, a node may determine when a resource should transition to multicast or unicast notification, and dynamically manage multicast group membership based on observation registrations and/or cancellations. By monitoring resource requests, a proxy may determine when to proactively refresh a cached representation of a resource. By monitoring timeouts and/or retransmissions, a client may dynamically adjust a timeout value to optimize communications.

    Abstract: A data processing system includes a host system and one or more expansion devices coupled to the host system over a bus. The host system may include one or more processors and a memory storing instructions, which when executed, cause the processors to perform autonomous driving operations to drive an autonomous driving vehicle (ADV). Each expansion device includes a switch device and one or more processing modules coupled to the switch device. Each processing module can be configured to perform at least one of the autonomous driving operations offloaded from the host system. At least one of the processing modules can be configured as a client node to perform an action in response to an instruction received from the host system. Alternatively, it can be configured as a host node to distribute a task to another client node within the expansion device. This host node in the expansion device can further cooperate with the host system via a host-to-host connection.

  • Publication number: 20200204637
    Abstract: The concept of a service layer message template is introduced, which may be a request template or a response template. Message templates may be created and stored at the service layer. Each message template may contain a set of request or response parameters and their values. Once in place, an application can send a request to the service layer that does not include the request parameters contained in the message template (i.e. request template); instead, a message template identifier may be sent. Since request parameters are included in the message template and stored at the service layer, communication overhead between the service layer and the application (or another service layer) may be reduced.

  • Publication number: 20200202061
    Abstract: Techniques and systems for implementing a general extensible layer mapping approach that maps between integrated circuit (IC) design database layers and process layers are described. A first IC design layout having in-design layers can be converted into a second IC design layout having derived layers, wherein said converting comprises mapping the in-design layers to the derived layers by applying a set of layer derivation rules to shapes in the IC design layout, and wherein the set of layer derivation rules implements a one-to-many mapping between the in-design layers and the derived layers. Next, a one-to-one mapping between the derived layers and process layers used in a parasitic extraction tool can be generated. Parasitic extraction on the IC design layout then be performed by providing the second IC design layout and the one-to-one mapping to the parasitic extraction tool.
