In some examples, a ground obstacle detection system of an aircraft is configured to generate and display a graphical user interface (GUI) that includes a graphical representation of a detected obstacle with which the aircraft may collide during a ground operation and an indication of an area of unknown associated with the detected obstacle. Instead of, in addition to, a GUI that includes an indication of an area of unknown associated with an obstacle, in some examples, a ground obstacle detection system to generate a GUI that includes at least two windows that present different views of an aircraft. At least one of the windows may include a graphical representation of an obstacle that may not be visible in the view of another window.

In some examples, a processor is configured to predict the presence of ice crystals (e.g., high altitude ice crystals) in a volume of airspace based on radar reflectivity values and one or more other types of information indicative of weather conditions in the volume of airspace, such as one or more of: ambient air temperature and altitude. For example, the processor may predict the ice crystals presence by at least estimating the iced water content level within a volume of airspace of interest based on radar reflectivity values for the volume of airspace (e.g., stored as in a three-dimensional buffer) and other information indicative of weather conditions of the volume of airspace. The processor may estimate the iced water content level using a model that relates the information indicative of weather conditions in and around the volume of interest to iced water content in the atmosphere.

This invention relates in general to the field of safety devices, and more particularly, but not by way of limitation, to systems and methods for providing advanced warning and risk evasion when hazardous conditions exist. In one embodiment, a vicinity monitoring unit is provided for monitoring, for example, oncoming traffic near a construction zone. In some embodiments, the vicinity monitoring unit may be mounted onto a construction vehicle to monitor nearby traffic and send a warning signal if hazardous conditions exist. In some embodiments, personnel tracking units may be worn by construction workers and the personnel tracking units may be in communication with the vicinity monitoring unit. In some embodiments, a base station is provided for monitoring activities taking place in or near a construction site including monitoring the locations of various personnel and vehicles within the construction site.

A data processing apparatus is provided, which includes processing circuitry. The processing circuitry is configured to acquire a data set from target detected by a detection apparatus, perform rendering of the data set, and generate a plurality of views arranged on a screen. Each view of the plurality of views includes a plurality of pixels. Each pixel included in the plurality of views is associated with a plurality of pieces of information including a first information displayed on the screen and a second information that indicates a view among the plurality of views to which the pixel belongs.

A driver alert system is configured to provide combined visual and audible spatial warnings. The system can include an object detection system to provide the location of at least one object relative to a vehicle, an audible output system including a plurality of speaker units, and a display unit. A control unit of the system can determine location of objects and generate combined visual and audible spatial warnings. Output of the combined visual and audible spatial warning can be controlled to output an audible alert indicating the location of the object relative to the vehicle passenger, and control a display unit to present a particle display output indicating the location of the object relative to the vehicle passenger. The system may include processes for control of combined visual and audible spatial warnings to account for changes in object position and vehicle heading.

A ship navigation assisting device includes: an area setter 304 that sets, for a target ship, a polygonal safe navigation area defined by a plurality of vertices and surrounding the target ship; a collision point calculator 305 that calculates, based on a speed of the own ship, a relative position between the own ship and the target ship, and a velocity vector of the target ship, collision points between each of the plurality of vertices constituting the safe navigation area and the own ship; and a collision danger area calculator 306 that connects the plurality of collision points calculated by the collision point calculator 305 to calculate a collision danger area.

A method for determining convective cell growth from weather radar reflectivity data includes receiving first weather reflectivity values and receiving second weather reflectivity values at a point in time subsequent to receiving the first weather reflectivity values, storing the first and second weather reflectivity values in cells of a three-dimensional buffer, for each of the first and second weather reflectivity values, calculating a vertically-integrated reflectivity (VIR) value for a column of cells in the three-dimensional buffer, the column of cells being associated with a latitude/longitude position, and comparing the VIR value for the second weather reflectivity values against the VIR for the first weather reflectivity values to determine a difference in the VIR values. Furthermore, the method includes displaying a cell growth hazard indication at a weather display in an area of the weather display that corresponds to the latitude/longitude position.

Aircraft, enhanced flight vision systems, and methods for displaying an approaching runway area are provided. In one example, an aircraft includes a display disposed in a cockpit area. A radar imaging and post-processing arrangement is in communication with the display via a processor. The radar imaging and post-processing arrangement is operative to generate a radar image of an approaching runway area, generate a symbology corresponding to the approaching runway area and/or compare the radar image to a synthetic vision (SV) database to align an SV runway area with the radar image to define an aligned SV runway area, and to communicate the symbology and/or the aligned SV runway area to the display.
