| 20150195033 | SELECTION OF COOPERATIVE STRATEGIES FOR RELAY NODES IN A WIRELESS NETWORK TO ENHANCE DATA THROUGHPUT - Systems and methods are disclosed for selecting cooperative strategies for relay nodes in a wireless network. In one embodiment, a cooperative strategy for a relay node in a wireless network is selected from a set of two or more cooperative strategies. The cooperative strategy defines a manner in which the relay node relays messages along a multi-hop route through the wireless network. Use of the cooperative strategy by the relay node is then effected. In one embodiment, the cooperative strategy is selected based on one or more channel quality based criteria. By selecting the cooperative strategy for the relay node, and in one preferred embodiment selecting cooperative strategies for all other relay nodes in the multi-hop route, performance of the wireless network can be improved. | 07-09-2015 |
| 20150237563 | Method for Improving Data Throughput in Wireless Networks - The proposed layer solution defines two or more layers of relay nodes to convey traffic data from a source node to a destination node. All of the nodes in a given layer were selected for that layer because they each satisfied a signal quality requirement specified for that layer, where all relay nodes defined in one layer simultaneously start transmitting in response to a received transmission. Due to the layered approach, the destination node may be configured to decode only the traffic data relayed by the relay nodes in the immediately preceding (final) layer while treating any remaining received signals as noise. As a result, only those access nodes most likely to significantly contribute to and improve the signal quality of traffic data received at the destination node are selected as relay nodes for a particular source-destination node pair. | 08-20-2015 |

| 20080280056 | Reactive Spray Formation of Coatings and Powders - An apparatus and method for open-atmosphere flame based spraying employs a nozzle to preheat, pressurize and atomize a mechanically pumped reactive and flammable liquid solution through a small orifice or a nozzle and then a set of pilot flames to combust the spray. The liquid feedstock is preheated to a supercritical temperature before reaching the nozzle and is pressurized before spraying due to a reduced size of the outlet port of the feedstock flow channel relative to the inlet. A supplementary collimating, or sheathing, gas is supplied to the flow channel of the feedstock and both the feedstock and the supplementary gas are uniformly heated before spraying. This arrangement helps to avoid clogging of the nozzle and results in satisfactory control of the properties of the particulate products of the spraying procedure. | 11-13-2008 |
