  • Patent number: 10525903
    Abstract: A traffic-light-detection system that visually determines a light-state of a traffic-light proximate to an automated vehicle includes a camera, a controller, and optionally a radar. The camera and the radar are on a host-vehicle. The camera renders a series-of-images of a traffic-light proximate to a host-vehicle. The radar detects radar-returns from the traffic-light. The controller is configured to determine a motion-pattern of the traffic-light based on the series-of-images and/or the radar-returns, and select a preferred-image from the series-of-images based on the motion-pattern. The preferred-image shows a light-source of the traffic-light characterized as being most directed at the camera when the motion-pattern indicates that the traffic-light is moving. The controller is further configured to determine a light-state of the traffic-light based on the preferred-image.

  • Patent number: 10514240
    Abstract: A missile system wherein a missile carrier delivers a plurality of submissiles over a target area. A passive or active scanner on the missile carrier repeatedly scans the target area as the missile carrier descends by drag brake over the target area. Submissile assignment to identified targets is performed at a selected altitude. A data processor controls the launching of the submissiles and actively guides the submissiles for substantial portions of their flights via optical fiber or wire links separately connecting each submissile to the missile carrier. Each submissile includes either passive or active identification devices enabling the data processor to track the submissiles individually. A missile assignment table stores a correspondence between identified targets and submissiles assigned thereto. Submissile assignment is effected on the basis of the strength of target signature.

    Abstract: A method for tracking a device determines correlations among locations of the device including a set of previous locations of the device and an initial estimate of a current location of the device, and determines, for each access point (AP), a current path loss exponent for the current location of the device using previous path loss exponents determined for the previous locations of the device and the correlations among the locations of the device. The method determines the current location of the device according to a path loss model using received signal strengths (RSS) of signals received from each AP at the current location and the current path loss exponent determined for each AP. The current path loss exponent for each AP are updated using the current location of the device and the RSS of signals received from the corresponding AP.

  • Patent number: 10509130
    Abstract: Disclosed herein are system, method, and computer program product embodiments for a GNSS interference and spoofing fast detection and mitigation system. A RF signal associated with a PNT device, such as a GNSS receiver, is received. The received RF signal is split into a plurality of sub-data signals. The received RF signal is re-routed by sending each of the plurality of sub-data signals to at least one of a processing module and a switching module. An anomaly associated with a second sub-data signal is detected. The anomaly is detected during a capture period of an adversarial attack on the PNT device, prior to corruption of any associated system depending on outputs from the PNT device. An output of a first sub-data signal of the plurality of sub-data signals is terminated based on the anomaly detected with the second sub-data signal.

  • Patent number: 10488158
    Abstract: An infrared signal processor is provided wherein infrared energy from objects on an area of the ground is directed towards a plurality of detectors disposed in a missile. The plurality of detectors scan the area of the ground and electrical signals produced by the detectors in response to the sensed infrared energy are processed to detect the presence of a ground target, typically a tank. Potential targets are detected, that is, are distinguished from ground clutter, by determining whether electrical pulses produced by the detectors in response to the sensed infrared energy have a proper pulse duration which is consistent with the width of a tank target. In particular, the electrical pulses are passed through a bandpass filter to filter signals produced by both ground clutter infrared energy and noise.
