  • Channel grey listing
    Patent number: 9191063
    Abstract: A wireless communication system grey-lists those channels that interfere with channels used by a second wireless communication system. The wireless communication system reduces the rate at which the grey-listed channels are utilized in the channel-hopping pattern, but does not completely eliminate use of the grey-listed channels.
    Type: Grant

  • Join key provisioning of wireless devices
    Patent number: 8369880
    Abstract: Wireless devices are provisioned to join a wireless mesh network by writing an individual or common join key and network identification information to the wireless device, and creating an association of the wireless device with a gateway of the network by providing the gateway with a unique device identifier for the wireless device. The writing of the join key to the wireless device is achieved without revealing the join key to a user.

  • Interface module with power over Ethernet function
    Patent number: 7835295
    Abstract: An interface module for use in a process monitoring and control system has an Ethernet port, a controller, and at least one segment I/O module. The Ethernet port is adapted to send and receive signals in an Ethernet protocol over a cable comprising a plurality of wires and to receive a voltage potential from at least one pair of the plurality of wires. The controller is coupled to the Ethernet port and powered from the received voltage potential. The at least one segment I/O module is coupled to the controller and is adapted to couple to an associated field device segment with at least one attached field device. The at least one segment I/O module is adapted to interact with the at least one attached field device on the associated field device segment.
