  • Patent number: 8331282
    Abstract: Various embodiments provide an apparatus and method for adaptive channel hopping in a mesh network. An example embodiment is configured to divide a time period into a plurality of frames; subdivide each of the plurality of frames into a plurality of slots, each of the plurality of slots providing a time segment for local data communication between nodes in a mesh network; enable a first node to dynamically assign itself a first channel for local data communication, the first node using the first channel to receive data communications destined for the first node; and communicate to other nodes of the mesh network information indicative of the first node's dynamic assignment of the first channel.

  • Patent number: 7900892
    Abstract: The present invention is directed to enhanced compositions that facilitate the pulling of cables through conduits. In one embodiment, the composition comprises a sufficient amount of boron nitride, which, upon application onto the cable surface, allows the cable to be pulled faster and/or with less force through the conduit than without the boron nitride present. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface. Lastly, the invention relates to an apparatus for distributing a cable-pulling composition comprising a block of boron nitride onto a cable as it is being pulled through a conduit.

  • Publication number: 20100316009
    Abstract: Various embodiments provide an apparatus and method for adapting wireless sensor network device operation to ambient RF noise. An example embodiment includes: initializing a noise threshold value to a default value; detecting an ambient RF noise level on a plurality of channels of a wireless network device; if the ambient RF noise level detected on a pre-determined number of channels is above the noise threshold value, adjusting the noise threshold value by an increment and retesting the ambient RF noise level on the plurality of channels; if the noise threshold value exceeds a pre-determined maximum noise threshold value, suspending data communications by the wireless network device; and if the ambient RF noise level detected on a pre-determined number of channels is below the noise threshold value, retaining the noise threshold value and enabling data communications by the wireless network device.

  • Publication number: 20100177708
    Abstract: Various embodiments provide an apparatus and method for establishing data communication in a time-synchronized mesh wireless network during time synchronization failures. An example embodiment includes experiencing circumstances adversely affecting synchronization of data communications between wireless network nodes; transitioning to an alert mode wherein a radio of a wireless network node is activated for a longer period of time relative to a normal operating mode; sending a message to at least one neighbor node; listening for a response from the neighbor node; and establishing data communications with the neighbor node upon receiving the response.

  • Publication number: 20090168703
    Abstract: Various embodiments provide an apparatus and method for admitting new devices in a self-healing, self-organizing mesh network. An example embodiment is configured to listen on a dynamically-determined frequency for the network management message; to send jamming messages to neighbor nodes in the wireless mesh network, if the network management message is not received; to receive the network management message from a neighbor node in response to the jamming messages; to synchronize a node timer to the received network management message; and to begin data communications with neighbor sensors using the synchronized node timer.
