摘要： Disclosed herein are system, method, and computer program product embodiments for detecting potentially unsafe wear levels in vehicle suspension systems. An embodiment operates by receiving acoustic signals of a vehicle suspension system, processing, the acoustic signals to generate training data, training a predictive learning algorithm to generate a predictive wear model and classifying the processed acoustic signals to indicate wear levels of one or more components of the vehicle suspension system. The trained predictive wear model subsequently predicts wear levels of the vehicle suspension system for notification to a cloud-based repository. Fleets of driverless vehicles may continuously monitor wear levels for timely maintenance before failure occurs.

摘要： Method, systems, and techniques for determining the age of an underground space are provided. In some embodiments, determining the age of an underground space comprises taking soil samples from a plurality of surface locations within a second underground space, analyzing the soil samples from the plurality of surface locations to determine an amount of a chemical compound for each soil sample, and determining an age of the second underground space using one or more relationships based on amounts of the chemical compound measured in a plurality of soil samples taken over a period of time in a first underground space and a baseline amount of the chemical compound at one or more locations remote from both the first underground space and the second underground space.

摘要： Systems and methods for automatically injecting effects in cyber-physical systems and their simulations are provided herein. In one example, the cyber-physical system under test can include one or more watch-point monitors that can analyze messages between components of the system to determine the presence of one or more particular patterns present in the messages being passed between components of the system during operation. In one or more examples, upon detection of one or more conditions matching a watch point, the systems and methods presented herein can activate an effect and inject it into the cyber-physical system under test based on the detected watch point. In one or more examples, the systems and methods can provide a domain-specific “effects language” (EL) that can allow a user to specify a watch point and an effect corresponding to the watch point.

摘要： Disclosed herein are system, method, and computer program product embodiments for utilizing parallel links to improve sub-network availability and latency performance for ATC traffic. An embodiment operates by receiving a generated message. The type of the generated message is determined, where the type is an air traffic control message or a non-air traffic control message. Based on the type of message, communication links are selected, where the communication links include parallel transmission links or a serial link. The method continues by copying the generated message and transmitting the copied message using the selected communication links. The method waits to receive an acknowledgement indicating receipt of the transmitted message. Upon identifying an acknowledgement, any of the copied messages not yet retransmitted are deleted.

摘要： Methods and systems for translating a natural language user query into a graph database query are described. In some instances, the methods may comprise receiving a first input from a user comprising a natural language query regarding data in a graph database; processing the natural language query using a named entity recognition (NER) machine learning model to extract named entities from the natural language query and tag them according to an entity type; processing the tagged named entities using a semantic similarity algorithm to identify corresponding nodes and edges, and their associated properties, in the graph database; processing the natural language query using an intent classification machine learning model to determine a user intent for the natural language query; and applying a user intent-based template to the identified nodes and edges to formulate a graph database query that corresponds to the natural language query.

摘要： Presented herein are systems and methods for generating a consistent set of signals to be processed by a PVT processor. In one or more examples, a GNSS receiver can receive a plurality of signals from a plurality of signal sources. In one or more examples, the systems and methods can generate clusters that have been vetted using cost functions so as to maximize the probability that any cluster that is sent to the PVT processor contains legitimate GNSS signals, and does not include any spoofed or otherwise illegitimate signals, thereby maximizing the probability that a PVT solution produced by the PVT processor is accurate.

摘要： Provided are systems and methods directed to identifying relationships between colloquial place names in a relational database. In some embodiments, a method of identifying relationships between colloquial place names in a relational database comprises receiving geographic location information; generating a vector corresponding to the geographic location; comparing the geographic location information vector to a plurality of colloquial place name vectors in a relational database that maps a plurality of colloquial place names to a plurality of corresponding colloquial place name vectors in a vector space, to generate a plurality of similarity scores that is calculated based on the geographic location information vector and each colloquial place name vector of the plurality of colloquial place name vectors; and identifying that one or more colloquial place names in the relational database are related to the geographic location information based on the plurality of similarity scores.

摘要： Disclosed herein are system, method, and computer program product embodiments for detecting spoofing of a navigation device. A plurality of anti-spoofing techniques are provided. The plurality of anti-spoofing techniques detect interference with data provided by one or more navigation devices for a plurality of threat situations. Positioning, timing and frequency characteristics associated with the one or more navigation devices are analyzed in order to identify a threat situation among the plurality of threat situations. Based on the identified threat situation one or more of the anti-spoofing techniques are executed. The one or more anti-spoofing techniques can be executed in parallel in order to provide various anti-spoofing detection techniques at the same time.
