    Abstract: A method and system to integrate information in a coordinated mission of a group of user vehicles is provided. The method comprises storing a call sign in a database for each user vehicle, among the group of user vehicles, in the coordinated mission; and identifying a speaker vehicle among the user vehicles by comparing a call sign from parts of speech (POS) with the stored call signs. The method further comprises highlighting the identified speaker vehicle in a common display of each user vehicle; and determining whether the POS from the speaker vehicle contains a reference to a point of interest (POI). The method generates a graphical symbol for the POI when the POS from the speaker vehicle contains a reference to the POI, and tags the graphical symbol at a location of the POI in the common display of each user vehicle.

    Abstract: A method for controlling an orientation of a searchlight on a vehicle is provided. The method comprises: obtaining a target range to a point of interest (POI) at a target; determining a searchlight position and attitude; calculating a three dimensional position at the POI using searchlight azimuth and tilt actuator angles, the target range, and the searchlight position and attitude, while a searchlight light head continues to point at the 3D target position despite changes in movement or orientation of the vehicle; calculating a desired searchlight orientation including azimuth angle and tilt angle to point the light head at the target through inverting a kinematic relationship between the vehicle and the searchlight; calculating compensatory actuator angles for a plurality of searchlight actuators to achieve the desired searchlight orientation based on error measurements calculated from a current orientation; and commanding the plurality of searchlight actuators to the compensatory actuator angles.

    Abstract: Systems and methods for an auto-land system for a rotorcraft are provided. The system includes, a search light (SL) assembly configured to receive user input directing the SL to a point of interest (POI) and determine an actual SL orientation and an actual SL range to the POI; and, a searchlight controller operationally coupled to the search light assembly, and configured to: responsive to receiving a command to auto-land at the POI, begin (i) generating a desired trajectory from the rotorcraft actual orientation and rotorcraft actual range to the POI; (ii) generating guidance commands for navigating the rotorcraft in accordance with the desired trajectory; (iii) monitoring an actual SL range and an actual SL orientation; and (iv) generating controlling commands for the searchlight assembly in accordance with the coordinates of the POI.

    Abstract: A lighting device including a plurality of light-emitting semiconductor devices. The light-emitting semiconductor devices are separated into at least two subgroups. The lighting device further includes a plurality of optics separated into at least two subgroups, which are arranged relative to the plurality of light-emitting semiconductor devices such that each one of the plurality of light-emitting semiconductor devices of a first subgroup is located at a focal point of a respective optic of a first subgroup of the plurality of optics, and such that each one of the plurality of light-emitting semiconductor devices of a second subgroup is located at a focal point of a respective optic of a second subgroup of the plurality of optics. The optical properties of the first subgroup and second subgroup of the plurality of optics are different. The lighting device further includes a controller module configured to control at least two current signals supplied from a power source to each of the at least two subgroups of light-emitting semiconductor devices, respectively. The controller module is configured to modify the beam width and the peak intensity of the emitted beam of light by varying the magnitude of the respective at least two current signals.

    Abstract: An ignition exciter system includes an igniter, a step-up transformer, a switch device, and a spark-sustain capacitor. The igniter has a spark gap across which a spark may be generated. The step-up transformer has a primary winding that is adapted to selectively receive direct current (DC) from a DC source, and a secondary winding that is coupled to the igniter. The switch device is coupled to the primary winding and is configured to selectively operate in an ON state, in which DC may flow through the primary winding, and an OFF state, in which DC may not flow through the primary winding. The spark-sustain capacitor is coupled to the igniter and is configured to charge from a DC source when the switch device is operating in the ON state, and at least selectively discharge across the spark gap when the switch device is operating in the OFF state.
