20150032892 | INTEREST FORWARDING FOR INTERACTIVE CLIENT ANONYMITY - In one embodiment, an intermediate node in a communication network receives a client interest with an indication of a client-requested reverse private path. The reverse private path is a label switched path toward a corresponding client with encrypted client information. In response to receiving the client interest, the intermediate node allocates a label for the reverse private path. The allocated label is mapped to a node from which the client interest is received. The intermediate node then forwards the client interest with the allocated label toward a server. In another embodiment, the server receives a client interest including a client-requested reverse private path from a particular intermediate node and determines a server interest. The allocated label for the client interest is inserted into the server interest which is forwarded toward the client via the particular intermediate node using the allocated label for the reverse private path. | 01-29-2015 |

20110166836 | FAST TRACKING METHODS AND SYSTEMS FOR AIR TRAFFRIC MODELING USING A MONOTONIC LAGRANGIAN GRID - Computer implemented methods and systems using a multidimensional Monotonic Lagrangian Grid (MLG) to sort and order locations of aircraft, are used for simulating, controlling, and optimizing aircraft traffic systems. The MLG is combined with algorithms for collision detection and resolution, separation assurance, and updating aircraft trajectories, and applied to test cases of the air transportation system. Physical locations describing aircraft traffic moving in complex paths are stored into a data structure of the multidimensional MLG algorithm. The moving aircraft traffic platforms are sorted and ordered on a grid structure in real space and in an indexing space, causing a monotonic mapping between indices of the grid structure and locations describing the plurality of moving aircraft. Computer operations using data stored in the multidimensional MLG determine control strategies for aircraft separation assurance and optimum routes to circumvent blockages in transport paths. | 07-07-2011 |
20120070790 | APPARATUS METHODS AND SYSTEMS OF UNIDIRECTIONAL PROPAGATION OF GASEOUS DETONATIONS - The detonation propagation in a channel geometry which suppresses detonation propagation in one direction, allows it in another direction, and does not create flow restrictions in the channel. The geometry consists of a series of divergent sections separated by wedges that form a sawtooth shape. The detonation fails to propagate through this geometry in one direction because the detonation front is weakened by diffraction, and reignition centers are isolated from the main channel. In an opposite direction, convergent parts of the geometry support the detonation propagation, because subsequent shock collisions with oblique walls that form convergent sections create powerful transverse waves. These powerful transverse waves help the detonation propagation or reignite it. | 03-22-2012 |
