Abstract: Meta-data is generated by a client proxy based on previous response data received from a server proxy in response to a previous request for a resource. A client in communication with the client proxy makes a new request for the resource. The client proxy creates a modified request by modifying the new request to include one or more elements of the meta-data, and sends the modified request instead of the new request to the server proxy. The server proxy compares the one or more elements to corresponding one or more elements of meta-data stored in a server proxy cache. If all compared elements match, the server proxy instructs the client proxy to deliver response data stored in a client proxy cache to the client. If any of the compared elements does not match, the server proxy sends new response data to the client proxy for delivery to the client.

Abstract: This application discloses a computing system implementing tools and mechanisms that can incorporate a validation system into a circuit design. The validation system can be configured to monitor at least a portion of an electronic device described in the circuit design. The tools and mechanisms can identify one or more trace signals associated with the electronic device to route to the validation system, and identify one or more trigger signals associated with the electronic device to route to the validation system. The tools and mechanisms can configure the validation system to detect a conditional event corresponding a state of the one or more trigger signals, and to transmit the trace signals associated with the electronic device for debugging in response to the detected conditional event.

Abstract: This application discloses a system to detect meta-stable glitches in a signal, such as an output of latch or other storage element. The system can include a sampling circuit configured to sample an output of a storage element. The system can include a mono-shot circuit configured to monitor the output of the storage element and generate a pulse when the monitored output of the storage element differs from the sampled output. The system can include a drive circuit configured to generate a glitch signal based, at least in part, on the sampled output, and to output the glitch signal in response to the pulse from the mono-shot circuit. The system can include an error detection circuit configured to receive the sampled output from the sampling circuit and the glitch signal from the drive circuit, and to generate an error signal when the sampled output differs from the glitch signal.

The method comprises receiving a network message from a network, inhibiting a sending of a user equipment message to the network and transitioning to a target state. The user equipment is adaptable/adapted and/or configurable/configured to receive a network message from a network, inhibit a sending of a user equipment message to the network and transition to a target state. The network message indicates the target state to which the user equipment is to transition.

Abstract: A control circuit (such as a smartphone processor) having access to a wireless two-way transceiver (such as a short-range transceiver) determines a need to offload execution of a task to a server and then determines present unavailability of that server. This control circuit then transmits a first message to the server to prompt the server to awaken. The control circuit then transmits a second message to the server to establish a wireless connection that the control circuit employs to offload execution of the task to the server. By one approach, the aforementioned first message can include a unique identifier for the server. If desired, this unique identifier can have been provided earlier by the server via a general broadcast.
