20110256935 | USE OF DYNAMIC BOUNDED REGIONS TO IMPROVE THE SCALABILITY OF DECENTRALISED ONLINE ENVIRONMENTS - In a decentralised multi-user online virtual environment, object responsibility is efficiently allocated to a controlling peer. The virtual environment is divided into a plurality of cells, and control of each cell is allocated to a responsible peer. Each responsible peer participates in a distributed hash table (DHT) to effect integration of the cells to effect the virtual environment. When a communications and processing load on the responsible peer controlling a cell exceeds a threshold, a second peer creates and takes control responsibility for an object comprising a bounded interest management region covering a region of load. Within the bounded interest management region, objects are removed or de-associated from the associated cell and instead associated with the bounded interest management region. | 10-20-2011 |

20130294885 | AUGMENTED FLUID TURBINE WITH RETRACTABLE WALL PANELS AND AERODYNAMIC DEFLECTORS - A fluid turbine apparatus for use with a turbine comprising a convergent section, a fluid turbine section adjacent to an outlet of the convergent section, and a divergent section adjacent to the fluid turbine section. The fluid enters through the convergent section and exits through the divergent section. The convergent and divergent sections are constructed using a modular grid-like structure supporting retractable wall panels. The internal vacuum created by the diffuser and the wind shear stresses on the convergent and divergent sections can be limited. Configurations of the convergent and divergent sections can be adjusted to suit prevailing wind velocities. Barriers of rotating deflectors are used to increase the effective area of the convergent and divergent sections during low wind conditions. Horizontally mounted aerodynamic deflectors may be used to decrease wind shear and drag on the divergent section, the turbine section, and on side walls of the convergent section. | 11-07-2013 |
