20100149019 | METHOD AND APPARATUS FOR ADS-B VALIDATION, ACTIVE AND PASSIVE MULTILATERATION, AND ELLIPTICAL SURVEILLANCE - A system and method are disclosed to track aircraft or other vehicles using techniques including multilateration and elliptical surveillance. Unlike conventional approaches that use time difference of arrival for multilateration at a fixed set of reception points, this technique allows targets to be tracked from a number of dynamic or moving reception points. This allows for triangulation/multilateration and elliptical surveillance of targets from combinations of fixed, fixed and moving or only moving ground-based receivers, sea-based receivers, airborne receivers and space-based receivers. Additionally this technique allows for ADS-B validation through data derived from only two receivers to assess the validity and integrity of the aircraft self-reported position by comparing the time of arrival of the emitted message at the second receiver to the predicted time of message arrival at the second receiver based on the self-reported position of the aircraft and the time of arrival at the first receiver. The benefits of using less than three receivers for validation include greater validation coverage areas using a smaller set of ground stations at a lower infrastructure cost. | 06-17-2010 |
20100198490 | EXTENSION OF AIRCRAFT TRACKING AND POSITIVE IDENTIFICATION FROM MOVEMENT AREAS INTO NON-MOVEMENT AREAS - At most airports, responsibility of air traffic control starts and stops at the entrance or exit to the runway movement areas, which are taxiways and runways. In the non-movement areas, such as hangers, ramps, and aprons, aircraft movements and separation are no longer the responsibility of air traffic control, but is the responsibility of other parties such as the airport itself, airlines, or other parties. The use of tracking technologies for air traffic control is therefore focused on the movement areas, not the non-movement areas, where there are limitations in aircraft tracking. Furthermore, many of the aircraft transmitting devices are switched off in non-movement areas exacerbating tracking problems in these areas. The present invention includes several methods including broadband multilateration, to extend aircraft tracking from the movement areas into non-movement areas without the need to extend special air traffic control equipment into those areas. | 08-05-2010 |

20110016205 | MULTIPLE INSTANCE COMMERCIAL BROWSER WEBSITE TEST AGENT - A website test environment invokes multiple instances of a commercial browser, and captures invocations of browser operations for gathering performance data without interference from other instances or multiple occurrences of the operating system (OS). Commercial browsers often employ constraints that assume only a single instantiation is executing on a particular machine. Configurations allow each instance to present as a separate user, thus avoiding conflicts that may arise from temporary files and network connections, for example. Each browser instance operates as a performance agent and dynamically links with a set of entry points for accessing performance related browser operations. As each agent invokes native (OS specific) machine functions for network access via particular entry points, configurations disclosed herein redirect the entry points to a collection layer of instructions (code) for capturing performance data in addition to invoking the native OS function called for by the browser operation. | 01-20-2011 |
