A sensor system for use in a vehicle that integrates sensor data from more than one sensor in an effort to facilitate collision avoidance and other types of sensor-related processing. The system include external sensors for capturing sensor data external to the vehicle. External sensors can include sensors of a wide variety of different sensor types, including radar, image processing, ultrasonic, infrared, and other sensor types. Each external sensor can be configured to focus on a particular sensor zone external to the vehicle. Each external sensor can also be configured to focus primarily on particular types of potential obstacles and obstructions based on the particular characteristics of the sensor zone and sensor type. All sensor data can be integrated in a comprehensive manner by a threat assessment subsystem within the sensor system. The system is not limited to sensor data from external sensors. Internal sensors can be used to capture internal sensor data, such a vehicle characteristics, user attributes, and other types of interior information. Moreover, the sensor system can also include an information sharing subsystem of exchanging information with other vehicle sensor systems or for exchanging information with non-vehicle systems such as a non-movable highway sensor system configured to transmit and receive information relating to traffic, weather, construction, and other conditions. The sensor system can potentially integrate data from all different sources in a comprehensive and integrated manner. The system can integrate information by assigning particular weights to particular determinations by particular sensors.

The disclosure generally relates to methods and systems anticipating a potentially threatening or dangerous incident, and providing varying levels of response to a user. In an exemplary embodiment, the present invention provides varying levels of assistance to a user prior to, during, and after a threatening incident occurs. By providing assistance prior to a threatening incident occurring, the system may be able to thwart potential attacks, bodily harm, robberies, break-ins, and other criminal or dangerous activity. The assistance can be, for example, in the form of deterrents, alerting first responders to go to the scene, sending security personnel to the scene, remotely monitoring the scene, remotely interacting with the scene, providing information and advice to the user.

Various types and levels of operator assistance are performed within a unified, configurable framework. A model of the device with a model of the environment and the current state of the device and the environment are used to iteratively generate a sequence of optimal device control inputs that, when applied to a model of the device, generate an optimal device trajectory through a constraint-bounded corridor or region within the state space. This optimal trajectory and the sequence of device control inputs that generates it is used to generate a threat assessment metric. An appropriate type and level of operator assistance is generated based on this threat assessment. Operator assistance modes include warnings, decision support, operator feedback, vehicle stability control, and autonomous or semi-autonomous hazard avoidance. The responses generated by each assistance mode are mutually consistent because they are generated using the same optimal trajectory.

A method and system or determining a flight path for an aircraft between an initial point and a destination point are described. An airspace is divide into a set of grid cells, and a flight path is established between the initial point and the destination point. A cumulative threat risk value for each of the grid cells is calculated, and an allowable threat risk per grid cell is established based on a rule set. An intermediate point from which to deviate the flight path is identified based upon an analysis of the cumulative threat risk values of the grid cells, if the threat risk value of any of the grid cells intersecting the flight path exceeds the allowable threat risk. A deviation from the intermediate point to a new intermediate point is determined such that the new intermediate point has a cumulative threat risk value lower than or equal to the allowable threat risk per grid cell. The flight path is adjusted between the initial point and the destination point to pass through the new intermediate point, thereby providing a modified flight path.

(2) It provides methods of RSE of interest selection when detailed map data is communicated or when some generic map data is available. (3) It provides methods of RSE of interest selection when other vehicles data is available. Other variations and cases are also given.

Threat risks to an enterprise are detected and assessed by assembling singular threats identified using both direct and behavioral threat indicators into composite threats to create complex use cases across multiple domains, and to amplify risks along kill chains of known attacks for early detection. Composite threat risk scores are computed from risk scores of singular threats to exponentially increase with the number of events observed along the kill chain. Composite threats are combined with normalized values of static risk and inherent risk for an entity of the enterprise to produce an entity risk score representative of the overall risk to the entity.

Methods and apparatus involve the mitigation of security threats at a computing endpoint, such as a server, including dynamic virtual machine imaging. During use, a threat assessment is undertaken to determine whether a server is compromised by a security threat. If so, a countermeasure to counteract the security threat is developed and installed on a virtual representation of the server. In this manner, the compromised server can be replaced with its virtual representation, but while always maintaining the availability of the endpoint in the computing environment. Other features contemplate configuration of the virtual representation from a cloned image of the compromised server at least as of a time just before the compromise and configuration on separate or same hardware platforms. Testing of the countermeasure to determine success is another feature as is monitoring data flows to identifying compromises, including types or severity. Computer program products and systems are also taught.
