  • Patent number: 8904371
    Abstract: Processing a dataflow program by a program development tool includes detecting a pair of actors defined by dataflow program instructions, wherein the pair of actors include a producer actor and a consumer actor, the producer actor supplying a data structure to the consumer actor via a path that comprises at least one connection and possibly also intervening other actors. An analysis is performed including analyzing one or more operations of the producer actor that involve the data structure and/or analyzing one or more operations of the consumer actor that involve the data structure. A result of the analysis is used as a basis for selecting a minimal amount of information from among a plurality of data handling possibilities concerning the data structure. A transformed program is produced in which the selected minimal amount of information is caused to be passed from the producer actor to the consumer actor.

  • Patent number: 8893080
    Abstract: Processing a dataflow program by a program development tool includes analyzing an actor defined by the dataflow program to identify original sequences of actions that can be reformulated to achieve greater execution parallelism while maintaining the same functionality as the original sequences. A processed dataflow program is produced comprising processed dataflow program instructions and decision point program instructions. The processed dataflow program instructions comprise alternative sequences of reformulated actions that achieve greater execution parallelism while maintaining the same functionality as the identified one or more original sequences. The decision point program instructions direct processing equipment to select and execute one or more of the alternative sequences of reformulated actions, wherein selection is based on state and token information in existence at the time of selection.

  • Patent number: 8831767
    Abstract: Methods and systems for monitoring a parameter of a measurement device during polishing, damage to a specimen during polishing, a characteristic of a polishing pad, or a characteristic of a polishing tool are provided. One method includes scanning a specimen with a measurement device during polishing of a specimen to generate output signals at measurement spots on the specimen. The method also includes determining if the output signals are outside of a range of output signals. Output signals outside of the range may indicate that a parameter of the measurement device is out of control limits. In a different embodiment, output signals outside of the range may indicate damage to the specimen. Another method includes scanning a polishing pad with a measurement device to generate output signals at measurement spots on the polishing pad. The method also includes determining a characteristic of the polishing pad from the output signals.

  • Patent number: 8671137
    Abstract: Methods and systems for personalizing access to client devices using near field communication is disclosed. In a transaction between a client and a server, the client may detect the presence of a computing device using near field communication, and the device may be identified as an assistive computing device. Based on this information, the client may send the assistive computing device user interface data such that the transaction can be completed on the assistive computing device instead of the client.
