Abstract: The present disclosure generally relates to methods, systems, apparatuses, and non-transitory computer readable media for processing radar signals of a MIMO radar system. By dynamically accounting for environmental noise both spatially and temporally, systems of the present disclosure can make radar-based systems more accurate and robust against noised-induced false detections, especially with respect to the use of sparse-receivers. More precisely, systems of the present disclosure may first process MIMO radar return data to identify one or more range-Doppler-elevation (RDE) bins exceeding a candidate detection criteria. Each identified candidate detection RDE bin may then be processed by a second search procedure to identify any azimuth bins (of the particular candidate detection RDE bin) exceeding a confirmed detection criteria. Each identified azimuth bin indicates a confirmed detection of a scatterer (e.g.

Abstract: Protrusions or holes with jagged edges formed on the lingual side of invisible aligner trays are provided. The protrusions or holes include two components and serve to irritate the tongue causing it to retract away from the incisors thus eliminating intruding force otherwise exerted by the tongue. A clear corrugated material is provided which is suited for making the aligner trays having the protrusions which otherwise would be difficult with standard thick material used. The lingual side protrusions are added by computer to the impressions taken from a patient's teeth such that the protrusions are formed on the dental model used to make the aligner trays.

Abstract: A system and method for predicting the failure and estimating the health of the industrial equipment or industrial measurement equipment and diagnosing the root cause of the incipient failures is provided. The system and method are applicable to different types of flow meters used in flow measurement applications and other industrial equipment or industrial measurement equipment. A means to detect anomalies in the industrial equipment or industrial measurement equipment diagnostic signals is provided and thereby allowing incipient failure prediction. The system and method provides the means to calculate the current state of health of the industrial equipment or industrial measurement equipment. Leading indicator/failed component in the industrial equipment or industrial measurement equipment can be tracked down in the event of a failure. The system and method provides the means to label the normal and abnormal periods in the historical data based on the available diagnostic alarms and signals.

Abstract: The present disclosure generally pertains to systems and methods for autonomously detecting and correcting anomalies in position information provided to aircraft using radio-frequency signals. By enabling autonomously detecting and correcting for anomalies in the operation of a ground-based solution entirely independent of GPS, systems of the present disclosure can make the provided position information more accurate and robust, thereby enhancing the effectiveness and safety of navigation systems using the provided position information. More precisely, systems of the present disclosure may employ a series of ground-based beacon transmitters to provide radio-frequency (RF) signal pulse with a highly regular frequency. A locating receiver can detect the arrival times of these pulses and use this information to detect and report certain anomalies. These reports may then be used to autonomously correct the detected anomalies.

Abstract: A radar-based system for communicating information to a vehicle uses spatially-encoded markers that are positioned proximate to a roadway traveled by the vehicle. The markers are designed to convey a unique radar signature that distinguishes the markers from other objects. The unique radar signature or marker characteristics are further interpreted by at least one controller on the vehicle as encoded messages. Marker distinguishing characteristics, such as size, shape, orientation and movement, provide distinct information to the controller. The controller may use the conveyed information to make control decisions for the vehicle or to display the conveyed information to occupants of the vehicle. In some cased, the controller may use the conveyed information to determine a location of the vehicle, such as a position of the vehicle within a lane.

Abstract: A method and system for operating an industrial process using an integrated quadratic controller (IQC) is provided for a single input multiple output system (SIMO). A target process value (PV) associated with an output of the industrial process is used to define an optimal output of the industrial process. Manipulated-variables (MVs) associated with a plurality of loads within the industrial process are utilized for controlling a rate of operation associated with the load impacting the PV of the industrial process. Quadratic programming (QP) is defined to optimize proportional action gains for the determined MVs given an update control variable PV. QP gain-modified proportional action are integrated into a control system of the industrial process and a modified control system to update MV output state map defining the multiple output to control respective loads in the industrial control process for achieving the target PV is generated.

Abstract: Systems and methods are provided for controlling a vehicular radar system. The radar scan patters used by the radar system when detecting objects in the environment around the vehicle can be controlled to gather additional information about the objects in the environment. The radar system can generate parameters about objects in the environment detected by the radar system. The parameters can then be evaluated to determine if the collection of additional information about the detected object in the environment is desirable. If additional information about the detected object in the environment is to be collected, a different radar scan pattern having different waveforms can be used to gather specific information about the object.

Abstract: Systems and methods are provided for controlling a vehicular radar system by selecting a radar scan pattern to be used by the vehicular radar system. The vehicular radar system can generate numerous different radar scan patterns to be used by the radar system to gather additional information about the objects in the environment. The vehicular radar system can incorporate a scheduler to adjudicate between the numerous generated radar scan patterns to determine the radar scan pattern that is implemented by the vehicular radar system. The scheduler can determine the radar scan pattern to be implemented by the vehicular radar system by prioritizing and ranking the different radar scan patterns. The radar scan pattern having the highest priority and ranking can then be implemented by the vehicular radar system.
