  • Patent number: 10321340
    Abstract: A telecommunications system includes a network device that detects a communication failure associated with a first communication network and generates a failure command for a remote device to transmit a failure signal over a second communication network. The failure signal represents the communication failure. A method includes detecting a communication failure associated with a first communication network, generating a failure command for a remote device to transmit a failure signal over a second communication network, and transmitting the failure command to the remote device. The network device may take a corrective action in response to receiving a recovery signal from the remote device.

  • Patent number: 10237019
    Abstract: A first communication node (110) receives a stream of code blocks from a second communication node (120) over an acknowledged connection (131.). The first communication node processes the received code blocks in accordance with at least one transport format parameter, TFP, detects errors in received code blocks, and transmits an acknowledgment in respect of groups of code blocks indicating whether at least one error was detected in the group. A first subset of the code blocks of a group are transmitted (e.g., modulated and demodulated) in accordance with a first TFP value, and a remainder of the code blocks are transmitted in accordance with a second TFP value. Because the first and second TFP values are independent, it is possible either to shorten the necessary processing time in the first communication node or, in connection with a predictive acknowledgment mechanism, to make the receiving-side processing of code blocks that do not contribute to the value of the transmitted acknowledgment more robust.

  • Patent number: 9924245
    Abstract: A plurality of measurement devices have analog sensors that measure the dynamic signals of physical events, sample the data into digital format with time synchronized clocks and generate time stamped Ethernet messages that are sent to a remote host. The remote host has a master clock that evaluates decoded time stamped messages from the measurement devices and sends back a message with a time correction error signal relative to the master clock. This feedback signal is used by the measurement devices to correct a local clock for data sampling and new message generation. Eight wire cable and associated connectors are used to handle three channels of traffic, with four wires dedicated to Ethernet messages as one channel, another two wires dedicated to reset and other commands as a second channel and another two wires to transmit power from the host to the measurement devices as a third channel.

  • Patent number: 9916471
    Abstract: A security mechanism in a database management system enforces processing restrictions stored as metadata to control how different pieces of a multi-nodal application are allowed to access database data to provide data security. The security mechanism preferably checks the data security restrictions for security violations when an execution unit attempts to access the data to insure the nodal conditions are appropriate for access. When the security mechanism determines there is a security violation by a query from an execution unit based on the security restrictions, the security mechanism may send, delay or retry to maintain data security. Nodal conditions herein include time restrictions and relationships with other columns, rows or pieces of information. For example, multiple processing units may execute together, but the security mechanism would prohibit these processing units to access specific pieces of information at the same time through the use of metadata in the database.

  • Publication number: 20150149839
    Abstract: A system and method for testing multiple wireless data packet signal transceiver devices under test (DUTs) with dynamic signal interference compensation. Transmit data packets originating from other DUTs are monitored during receive signal testing of a selected DUT for concurrent occurrences of transmit and receive data packets. From this, it can be determined whether a failure to receive a responsive data packet, such as an acknowledgement, from the selected DUT is likely due to interference from a transmit data packet from another DUT being at least substantially concurrent with the receive data packet to which the selected DUT was expected to respond. If so, one or more receive data packets can be added to the receive signal sequence to extend the test and determine an accurate packet error rate (PER) without requiring a repeat of the full test.

Each VSG is configured to generate multiple RF test signals and send them to multiple devices under test simultaneously. Similarly, each VSA is configured with multiple signal receiving modules connected to a single controller or memory. Each signal receiving module receives an RF signal from a device under test, converts it to a baseband digital signal, and transmits this digital signal to the VSA's memory. A single RF testing system can employ multiple such VSGs and VSAs, each capable of evaluating multiple devices under test. Each VSG/VSA can further be tuned for operation in discrete or defined frequency bands, which are narrower than those for conventional RF testers, and which can correspond to various wireless standards.

    Abstract: A communication link analyzer is disclosed for analyzing a communication link. The communication link analyzer may analyze bitstreams that have been FEC encoded and are transmitted according to one or more 10 Gigabit Ethernet standards, 40 Gigabit Ethernet standards, and other such standards. The communication link analyzer may maintain a running count of the errors detected for the bit positions of a 2112-bit FEC-encoded datablock. These errors may include, but are not limited to, baseline wander, deterministic jitter, and predictive-interval errors. When a given error threshold is met or exceeded for one or more received bitstreams, the communication link analyzer may then attempt a diagnosis of the communication link. Using previously provided empirical data, the communication link analyzer may provide a diagnosis of the communication link based on the error type threshold that was met or exceeded and the bit position associated with the error type threshold.

  • Patent number: 8874980
    Abstract: A chip applied to a serial transmission system includes an input terminal, a core circuit, an output terminal, a first transmission line, a second transmission line and a spare transmission line, where the input terminal is used to receive an input signal from a source outside the chip, the output terminal is used to output an output signal, the first transmission lines is coupled between the input terminal and the core circuit, the second transmission line is coupled between the core circuit and the output terminal, and the spare transmission line is coupled between the input terminal and the output terminal. When the core circuit cannot process the input terminal normally, the input signal is directly transmitted to the output terminal via the spare transmission line, and the input signal serves as the output signal to be outputted from the output terminal.

  • Patent number: 8839355
    Abstract: A method and system for preserving privacy related to networked media consumption activity including: Source privacy zones are defined and associated with privacy standards. Privacy standards include frequency criteria governing the storage of datasets including information associated with networked media consumption activity collected from the source privacy zone. Transaction requests including a networking protocol address are received over a network from a client device at a target location by a networked privacy system. The source privacy zone associated with the client device is identified. Using the networking protocol address to access characteristics having characteristic value(s), a dataset can be created including associating the networked media consumption activity with the characteristic and characteristic value(s). The dataset is pre-processed to comply with the privacy standards. The networking protocol address is discarded.

  • Patent number: 8839056
    Abstract: Systems, methods, and devices related to testing receive equipment. A test signal generator is coupled to both a receiver and an antenna. The receiver is also coupled to the antenna and a test signal verifier. A test signal is synthesized at the generator and is routed to the receiver. Once the verifier verifies that the test signal was received by the receiver, this ensures that the equipment coupled to the receiver, as well as the receiver itself, is in operating condition. Switches or other means of routing the test signal between the different components of the system can also be present.
