A method for detecting Global Navigation Satellite System (GNSS) spoofing is provided. The method includes receiving signals at a GNSS receiver; processing the signals to determine a calculated position; searching a list of distance measuring equipment (DME) transponders around the calculated position to select a set of DME transponders; sorting the set of DME transponders based on a respective distance between the calculated position and a respective position of each of the DME transponders; selecting a subset of the DME transponders based on the sorting; for each of the subset of the DME transponders, incrementing a counter when a difference between a real slant range, determined by communicating with the DME transponder, and an expected slant range based on height, position and known location of the DME transponder, exceeds a first threshold; and when the counter is greater than a second threshold, indicating that the position is spoofed.

A system may port a data model into a strict schema system, translate the data model into a transformation rule definition, fit the transformation rule definition to a transform action, receive strict schema data, perform the transform action on the strict schema data based on the transformation rule definition to form rough data, and execute filtering and enriching operations on the rough data to form loose schema data.

Transforming data of strict schema structure database

A computer-implemented method includes analyzing, by a processing unit, a relational database to discover a plurality of static relationships between a plurality of data fields captured in two or more tables. The processing unit can discover a plurality of entity relationships based on observing application-generated queries and results of accessing the relational database in response to one or more test triggers. The processing unit can build one or more relation graphs based on the static relationships and the entity relationships to link a plurality of nodes with one or more edges that define at least one relationship between the nodes. One or more class graphs are formed having a reduced number of edges than the one or more relation graphs. The processing unit can generate one or more result data graphs using the one or more class graphs as a graph database model of the relational database.

Extraction of relationship graphs from relational databases

A display substrate and a manufacturing method thereof are disclosed. The display substrate is divided to have a non-pixel region and a color pixel region. The manufacturing method includes: forming a thin film transistor (TFT) on a base substrate in the non-pixel region; forming a passivation layer on the TFT; forming a color filter on the passivation layer in the color Pixel region; forming a planarization layer on the passivation layer and the color filter; thinning a thickness of a portion of the planarization layer located in the color pixel region; and forming a display electrode on the planarization layer and connecting the display electrode to a drain electrode of the TFT through a via hole.

Display substrate and manufacturing method thereof

Disclosed are methods, systems, and non-transitory computer-readable medium for vehicle information reporting of a vehicle using Global Navigation Satellite System (GNSS) receivers and a satellite communication transceiver for a satellite system. For instance, the method may include obtaining GNSS data to determine position, altitude, speed, track, or vertical rate information for the vehicle; receiving inputs from timers, sensors, or a user interface of the vehicle; determining whether to transmit a message based on rules applied to the obtained GNSS data and the received inputs; in response to determining to transmit the message, compiling the message based on a message content rule, the message being configurable with respect to a maximum size of a radio-determination-satellite service (RDSS) message of the satellite system, the message including an emergency message when the rules indicate an emergency situation; and transmitting the message via the satellite communication transceiver to a satellite of the satellite system.

Methods are provided for repairing a vane assembly, where the vane assembly includes an inner annular housing, an outer annular housing, and a vane extending therebetween. In one embodiment, the method includes removing an identified section of the vane to thereby form a pocket in an inner surface of the outer annular housing, a slot through the inner annular housing, and an edge on the vane, inserting a replacement vane portion with an advanced coating through the formed slot such that a first edge of the replacement vane portion is disposed in the pocket and at least a portion of the first edge is spaced apart from at least a portion of the outer annular housing inner surface, and welding a section of the replacement vane portion to the annular inner annular housing. The repaired vane assembly is also provided.

The present invention provides a compact coaxial nozzle useful in laser welding operations where the welding piece has a restricted or confined geometry. The nozzle is generally conical in shape, terminating in a relatively small tip. The nozzle includes a central laser discharge opening. The conical shape allows movement of the nozzle in confined areas. The nozzle includes a cooling jacket for proving coolant to the nozzle. The nozzle also includes a powder mixing chamber that provides good mixing of powdered filler material with a coaxial discharge around the laser. Finally, the nozzle further provides for inert gas to pass from an upper inlet, through passageways, out of a ring discharge. The ring discharge is also coaxially disposed around the central laser. Further the ring discharge provides mixing of the inert gas in order to minimize turbulent flow problems associated with restrictor plates.

A method is provided for repairing Z-notch wear surfaces on low pressure gas turbine engine turbine blades. The method is directed to turbine blades made of superalloy Inconel 713. Powdered Inconel 713 is welded to the Z-notch wear surface by directing an Nd:YAG laser beam upon the material. The laser beam is focused and traverses the wear surface in a stich-like pattern. The method allows Inconel 713 turbine blades to be repaired with the same material in a manner that does not generate cracking in the matrix material.
