  • Patent number: 10999708
    Abstract: Embodiments described herein are directed to a tracking objects using a cognitive heterogeneous ad hoc mesh network. Participant objects transmit notification signals to inform other participant objects in line-of-sight of their position and movement. The participants also utilize echoes of the notification signals to detect and estimate the position and movement of non-participant objects. Participant objects can then share this positional information with one another to refine the estimated position and movement of non-participant objects. The position of each other participant and non-participant object is updated based on an individualized update rate that dynamically changes based on the distance and velocity of closure between the participant and the other participant or non-participant object.

  • Patent number: 10963319
    Abstract: A method, system and computer program product for enhancing privacy of event data. Event sensor data (e.g., body temperature, heart rate data) is received and analyzed by a subscriber to form a probability of assigning a user identity to the received event sensor data. The user of the event sensor data is then assigned with a temporary membership to a cohort (related group of users that share common characteristic(s) or experience(s)) to hide the identity of the user in response to the probability of assigning the user identity to the received event sensor data exceeding a threshold. Actions may then be performed based on the temporary membership to the cohort in order to ensure that the probability of assigning a user identity to the received event sensor data does not exceed the threshold. In this manner, privacy of the user's sensitive data is enhanced.

  • Patent number: 10955261
    Abstract: An air data computer senses acceleration and rotational rate of an aircraft with an inertial sensor assembly of the air data computer. The air data computer determines first attitude information of the aircraft based on the acceleration and rotational rate sensed with the inertial sensor assembly. The air data computer receives second attitude information of the aircraft from a source external to the air data computer, and determines attitude correction values based on the first attitude information and the second attitude information. The air data computer applies the attitude correction values to the first attitude information to produce error-corrected attitude information that is output from the air data computer.

  • Patent number: 10699586
    Abstract: An auto-ICAS compliant system and method of avoiding collisions between aircraft linked by a Link 16 network comprises establishing an ICAS datalink between aircraft less than 10 nautical miles apart. Datalink messages generated and processed by ICAS datalink modules are transmitted and received by Link 16 receivers rather than dedicated ICAS transceivers. The datalink messages are embedded within the propagation delay portions of Link 16 timeslots and exchanged among up to 10 nearby aircraft at a data rate of up to 20 Hz each. Because each Link 16 timeslot can contain a Link 16 message and two 768-bit ICAS datalink messages, conventional Link 16 communication is not impeded. Datalink messages can be software encrypted. Link 16 messages can be encoded using an enhanced throughput Link 16 protocol that includes fewer preamble pulses and/or eliminates STN information. Embedded datalink messages can be transmitted at 1 Watt by a MIDS-JTRS CMN4.

  • Patent number: 10061018
    Abstract: A system for identifying a drone is adapted to determine a base threat value for a drone. The system includes a scanning system, configured to obtain data that is stored in a pattern database. A timer that has a data structure for storing a counter initialized to a predetermined value, the timer being operable to iteratively increment the counter if the counter value is less than a timer increment. A microprocessor is programmed with instructions to receive information from the scanning system about the drone. Then, to store the information in a pattern database. After that, to determine a base threat value of the drone based on the information stored in the pattern database. Finally, to communicate the base threat value to a user so that the user can determine whether the drone is a friend or a foe.

  • Patent number: 9997079
    Abstract: This disclosure is directed to a detection and avoidance apparatus for an unmanned aerial vehicle (“UAV”) and systems, devices, and techniques pertaining to automated object detection and avoidance during UAV flight. The system may detect objects within the UAV's airspace through acoustic, visual, infrared, multispectral, hyperspectral, or object detectable signal emitted or reflected from an object. The system may identify the source of the object detectable signal by comparing features of the received signal with known sources signals in a database. The features may include, for example, a multispectral signature emitted or reflected by the object. Furthermore, a trajectory envelope for the object may be determined based on characteristic performance parameters for the object such as cursing speed, maneuverability, etc. The UAV may determine an optimized flight plan based on the trajectory envelopes of detected objects within the UAV's airspace.

  • Patent number: 9678205
    Abstract: A method to automatically and continuously provide surveillance based on central and/or distributed surveillance of presence, positions, movements and movement pattern of one or more vessels in narrow waters, a sailing lane or where danger of collision with other vessels or other fixed or floating objects may occur. A vessel emits a sweeping signal that repeatedly hits one or more detectors, which detect the character of the sweeping signal and the time intervals between the signal hits on the respective detector. The exact position of the vessel and/or movements is calculated at least on the basis of trigonometric principles, and the vessel identity is produced by using signal analysis to extract the characteristic signal sequences from the received detection signals, which are related to the transmitted radar signal(s) from the vessel(s).
