20150331099 | SYSTEM AND METHOD FOR AIRCRAFT NAVIGATION BASED ON DIVERSE RANGING ALGORITHM USING ADS-B MESSAGES AND GROUND TRANSCEIVER RESPONSES - A method of aircraft navigation via receiving signals emitted by other aircraft and corresponding reply message transmitted by ground transceivers and the using a new diverse-ranging algorithm that solves for the positions of a eavesdropping aircraft and the positions of direct-reply aircraft emitting the signals received by the eavesdropping aircraft. | 11-19-2015 |
20140111372 | SENSOR SYSTEM AND METHOD FOR DETERMINING TARGET LOCATION USING SPARSITY-BASED PROCESSING - A system and method for an arrayed sensor to resolve ambiguity in received signals, improve direction of arrival accuracy and estimate a location of one or more targets in an environment including signal interference. | 04-24-2014 |
20120323475 | AUTOMATIC DETERMINATION OF AIRCRAFT HOLDING LOCATIONS AND HOLDING DURATIONS FROM AIRCRAFT SURVEILLANCE DATA - A method of using airport surveillance data to determine a location of a delay and an amount of time a vehicle is subjected to the delay during a movement of the vehicle between locations including obtaining a time-ordered sequence of data points representing the movement of the vehicle, creating a speed vector (sv) for each data point, replacing ground speed elements in the speed vector (sv) with a one when the ground speed element is less than a speed threshold, performing a spatial density test on each data point in a sequence of consecutive one entries, defining a starting and stopping index for a consecutive sequence of data points as a preliminary hold, determining whether to merge adjacent preliminary holds, determining a time duration of each preliminary hold and eliminating any preliminary hold having a time duration less than a predetermined time duration and outputting the results. | 12-20-2012 |
20120252503 | SYSTEM AND METHOD FOR PASSIVELY DETERMINING OWN POSITION LISTENING TO WIRELESS TIME SYNCHRONIZATION COMMUNICATIONS - The system and method of the present invention provides a mobile node (e.g., target), such as an aircraft, vehicle or mobile piece of equipment, the ability to determine its own position by passively listening to wireless time synchronization communications, such as IEEE 1588 Precision Time Protocol (PTP) messages, exchanged between nodes over a wireless network. | 10-04-2012 |
20120218149 | LIGHTWEIGHT AIR-COOLED TRANSMIT/RECEIVE UNIT AND ACTIVE PHASED ARRAY INCLUDING SAME - A light-weight, air-cooled transmit/receive unit is provided, including a first external cover member, an opposed second external cover member, and a central housing unit, including thermal management means, interposed between the first and second external cover members. A transmit/receive circuit board, including components and an integrated and common radiating element for at least one channel, is interposed between a first surface of the central housing unit and the first external cover member, and a controller circuit board and a power converter circuit board are interposed between an opposed second surface of the central housing unit and the second external cover member. | 08-30-2012 |
20120215075 | CORPSMAN/MEDIC MEDICAL ASSISTANT SYSTEM AND METHOD - The present invention is a corpsman/medic medical assistant system that includes a portable transmit/receive pack, sensor leads for first and second physiological sensor subsystems and a corpsman/medic medical assistant control unit that includes a wireless transceiver. The portable transmit/receive pack has a sealed housing that includes the first and second physiological sensor subsystems, at least one processor running at least one algorithm, a wireless transceiver, and memory with a front panel that includes a display, at least one event key, a treatment button for recording treatment data, a timer, an observation button for recording observation data, and a plurality of physiological trend indicators. The algorithm determines a current physiological trend status of the patient based on the plurality of physiological measurements, and the transmit/receive pack links to the control unit by the wireless transceiver and receives the current physiological trend status of the patient. | 08-23-2012 |
20120143483 | AUTOMATIC DETERMINATION OF AIRCRAFT HOLDING LOCATIONS AND HOLDING DURATIONS FROM AIRCRAFT SURVEILLANCE DATA - A method using airport surveillance data to output a location of a delay and an amount of time a vehicle is subjected to the delay during a movement of the vehicle between two locations, the delays being observed in the surveillance data as a knot of several data points. A first method is used to identify proposed knots based on distances between individual data points within the data. A second method is used to identify proposed knots based on the speed of the vehicle. Another method can be used to separate proposed knots have been incorrectly joined together. This method performs the separation by arranging the data points into a two-dimensional grid to form clusters of grid cells having data points. The location of the individual cells is then analyzed to determine whether clusters should be separated. Each of the remaining clusters defines a hold where the vehicle is delayed. | 06-07-2012 |
