20090083034 | VEHICLE CONTROL - The present invention relates to voice-activated vehicle control, and to the control of UAVs (unmanned air vehicles) using speech in particular. A method of controlling a vehicle is provided that includes receiving one or more instructions issued as speech and analyzing the speech using speech recognition software to provide a sequence of words and a word confidence measure for each word so recognized. The sequence of words is analyzed to identify a semantic concept corresponding to an instruction based on the analysis, and a semantic confidence level for the semantic concept identified derived at least in part with reference to the word confidence measures of the words associated with the semantic concept. A spoken confirmation of the semantic concept so identified based on the semantic confidence level is provided, and the semantic concept is used to provide a control input for the vehicle. | 03-26-2009 |
20100246445 | Method for Maintaining Links in a Mobile Ad Hoc Network - The present disclosure relates to mobile ad hoc networks, and to ad hoc networks using aircraft in particular. A method of maintaining data links to and from a source node in an ad hoc mobile network is provided. The network comprises nodes including neighbour nodes corresponding to nodes within range for direct communication with the source node. The neighbour nodes comprise active neighbour nodes and inactive neighbour nodes, the active neighbour nodes being connected to the source node via respective active data links and the inactive neighbour nodes having respective inactive data links to the source node. One or more lost neighbour nodes are identified and revised configurations of data links are considered that account for the change in neighbour nodes. A new configuration is selected based at least partly on the cost of sending messages from the source node using the revised configurations. | 09-30-2010 |
20100246492 | Method for Routing in a Mobile Ad Hoc Network - The present disclosure relates to mobile ad hoc networks that may include aircraft. Embodiments of the present invention provide a method of providing routing data for use in routing a message from a source node to available destination nodes through a mobile ad hoc network. A list of neighbour nodes corresponding to nodes within range for direct communication is obtained. For each neighbour node, a cost function is used to calculate the lowest costs of sending messages to respective available destination nodes; and routing data is generated based on these lowest costs. A message may be routed to the most suitable neighbour node by reference to the routing data. | 09-30-2010 |
20120134237 | Unattended Ground Sensors - The present disclosure relates to unattended ground sensors for detecting the presence of a pedestrian or vehicle in a monitored area using seismic sensors. Networks of simple and inexpensive sensors are disclosed that may be rapidly deployed. The networks may be formed from a dense array of low cost ground sensors having low sensitivity. | 05-31-2012 |
20130007879 | Method of and Apparatus for Monitoring for Security Threats in Computer Network Traffic - A method of and apparatus for monitoring for security threats in computer network traffic is disclosed. The method comprises operating computer processing means ( | 01-03-2013 |
20130308426 | DEPLOYABLE GROUND SENSORS - A method includes enabling a power supply of a ground sensor device to provide power to one or more components of the ground sensor device based on one or more rotations of a rotor of the ground sensor device. | 11-21-2013 |
20140074339 | Network of Unmanned Vehicles - The present invention provides a co-operative network of unmanned vehicles that participate in co-operative task allocation. Each unmanned vehicle comprises a computer system with an executive level configured to control motion of the unmanned vehicle and an automatic decision level configured to communicate with other unmanned vehicles, to receive task descriptions, to participate in task allocation, and to provide descriptions of tasks to be performed to the executive level for execution. Each unmanned vehicle submits a bid for each task it can perform, the bid reflecting an execution cost for the task. The bids are compared and the task effectively auctioned to the unmanned vehicle with a lowest execution cost. Each unmanned vehicle builds a task plan from its allocated tasks, decomposes the associated task descriptions into elementary task descriptions and forwards the elementary task descriptions in a format suitable for the executive level to execute. | 03-13-2014 |
20140129059 | METHOD AND APPARATUS FOR EXTENDING THE OPERATION OF AN UNMANNED AERIAL VEHICLE - A method of extending the operation of an unmanned aerial vehicle (UAV) is disclosed. The method comprises detecting that an energy storage device on board the UAV is depleted below a threshold level, landing the UAV at a base station, and initiating operation of the base station to cause a replacement mechanism thereof to remove the energy storage device on board the UAV from the UAV and to replace this with another energy storage device. | 05-08-2014 |
