Abstract:
A wind turbine system (100) is provided. The system (100) may include a plurality of blades (102). Each of the blades (102) may include a first pole (104), a second pole (106), a third pole (108) and at least one flexible member (112). The first pole (104), the second pole (106) and the third pole (108) may be positioned upright. A first end (110) of each of first pole (104), the second pole (106) and the third pole (108) may be disposed at corners of a triangle (134). The flexible member (112) may be connected to at least the first pole (104) and the third pole (108) such that the second pole (106) is disposed between the first pole (104), the flexible member (112) and the third pole (108).

Abstract:
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, to mitigate a denial of service attack to a power line communication (PLC) network. A first node of the PLC network may activate a countermeasure that enables the PLC network (including the first node and a second node) to continue to communicate when one or more transmissions associated with a denial of service attack are injected onto the communication medium. This disclosure includes several techniques to detect a denial of service attack and several countermeasures that may be implemented. For example, a countermeasure may include the use of a custom preamble or a custom priority resolution symbol that is specific to the PLC network. The first node and the second node may disregard transmissions that do not conform to the custom preamble or custom priority resolution symbol.
Abstract:
A process is disclosed for producing functionalized olefins from a fuel source including an organic compound including a functional group. Useful fuel sources include, for example, biofeedstocks (e.g., carbohydrates, triglycerides, polyols, and biodiesel). The process is preferably carried out by partial oxidation. The overall process can be carried out autothermally.

Abstract:
A system comprising a plurality of nodes forming a network and a link-state packet capable of being transmitted by a source node in the network to a destination node in the network over a communication link; wherein the source node subtracts a transmission cost associated with the communication link from a time-to-live value associated with the link-state packet prior to transmitting the link-state packet to the destination node. Each node in the network may be configured to use a routing protocol, such as a no-sight routing protocol, to assign the transmission cost to the communication link.

Abstract:
A system comprising a plurality of nodes forming a network, the plurality of nodes comprising source nodes and destination nodes; wherein a propagation limit restricts the travel of link-state information transmitted by the sources nodes to a subset of destination nodes within the network. A network-layer protocol provided at a layer above that of the network facilitates communication between nodes within and outside of this subset of nodes.
Abstract:
The systems and methods described herein include, among other things, processes for providing low latency packet transport in ad hoc networks. To this end, the systems, in certain embodiments, employ an architecture for communication nodes in MANETs, in which the delay introduced in “routing” or “relaying” the packet is reduced. In these systems invention, the data plane of the OSI stack at relay nodes is collapsed so that bits entering the node are re-energized “on-the-fly”, with only a brief pause. A transit key in each packet, inserted by the originator of the packet, is used to index into a transit table to determine one of three actions to perform—drop, keep, or retransmit the packet. A control plane determines, for each packet, whether it should be re-energized or not. The control algorithm ensures that only nodes along the path from the source to the destination re-energize (relay) the packet.
Abstract:
The invention relates to systems and methods of operating a wireless network including allocating and assigning frequency channels using a dynamic and distributed process. For example, a network node in an ad hoc wireless network will assign frequency channels to one or more of its transceivers based on at least one of a list of allowed frequency channels and a neighbor-frequency channel list.
