  • Publication number: 20160128111
    Abstract: A communication device for establishing wireless peer-to-peer connections includes a network interface, a memory and a processor. The processor receives a command to initiate a wireless peer-to-peer connection with a second device, sets an intent parameter to a default value and stores the intent parameter in the memory. The processor determines whether a link has been established between the network interface and a wireless base station. When a link has been established, the processor adjusts the intent parameter based on a channel type of the link. The processor receives a second intent parameter from the second device via the network interface, and determines whether the intent parameter is greater than the second intent parameter. When the determination is affirmative, the processor configures the communication device as an access point for the peer-to-peer connection; and when the determination is negative, the processor configures the communication device as a client for the peer-to-peer connection.

  • Patent number: 9327489
    Abstract: A method for controlling feature characteristics in a flexographic printing system that forms a printed pattern on a substrate by applying ink from an ink reservoir using a flexographic printing plate mounted on a plate cylinder. An imaging system is used to capture an image of the pattern printed on the substrate, and the captured image is analyzed to determine a feature characteristic of one or more features of the printed pattern. A control system automatically controls an amount of solvent used to replenish the ink in the ink reservoir responsive to the determined feature characteristic.

  • Patent number: 9233531
    Abstract: A flexographic printing system uses a flexographic printing plate to produce printed patterns on a substrate. An ink recirculation system is used to reduce variability in system performance resulting from ink viscosity changes. A recirculation pump moves ink through an ink recirculation line connected to an ink reservoir. A metering pump adds a controlled flow rate of solvent from a solvent replenishment chamber into the ink recirculation line, thereby providing replenished ink. The replenished ink is returned to the ink reservoir through a distribution tube that includes a plurality of supply ports at a plurality of spaced apart locations across a width of the ink reservoir. A control system is used to control the flow rate of solvent provided by the metering pump.

  • Patent number: 9076016
    Abstract: One or more network devices receive user criteria for providing anonymization of data from a user device and generate a default workflow for achieving the user criteria. The network devices provide, to the user device, the default workflow and receive user input to the default workflow. The network devices generate and send, based on the user input, final workflow instructions for transmitting data from the user device. The network devices also receive anonymized data transmitted from the user device based on the final workflow instructions. The network devices can provide trend observations of the anonymized data for use by third parties without granting access to the anonymized data.
