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 moving an illumination spot of a searchlight beam at a constant groundspeed. The method includes receiving state data comprising an attitude for the mobile platform. The method computes an elevation angle, theta, of the beam as a function of the attitude, an elevation actuator angle and a known mounting orientation for the searchlight. Responsive to receiving a searchlight control command from a user input device, the method determines a respective rate of change of theta, dtheta/dt, and rate of change of Psi, dPsi/dt, required to maintain the constant groundspeed of the illumination spot, as a function of the state data. The method updates theta responsive to the determined dtheta/dt and generates actuator control commands for an elevation actuator based thereon. The method updates Psi responsive to the determined dPsi/dt, and generates actuator control commands for an azimuth actuator based thereon.

Abstract: Methods and systems are provided for autonomously operating a retractable lighting arrangement. One method involves obtaining a current speed of the vehicle when the lighting arrangement is in an extended state, and when the current speed is greater than a threshold when the lighting arrangement is in the extended state, verifying one or more illumination elements associated with the lighting arrangement are in a deactivated state and thereafter automatically signaling an actuation arrangement associated with the lighting arrangement to transition the lighting arrangement from the extended state to a retracted state.

Abstract: A spherical electromagnetic machine includes a spherical stator, a plurality of longitudinal slots, a plurality of latitudinal slots, a plurality of longitudinal coils, a plurality of latitudinal coils, a first hemispherical shell rotor, and a second hemispherical shell rotor. The longitudinal slots and latitudinal slots are formed in, and are spaced evenly around, the outer surface. The longitudinal coils are disposed within a different one of the longitudinal slots. The latitudinal coils are disposed within a different one of the latitudinal slots. The first and second hemispherical shell rotors are mounted for rotation relative to the spherical stator body and have magnets on their inner surfaces. A Lorentz force causes movement of the first and second hemispherical shell rotors when electrical current is supplied to one or more of the longitudinal coils or to one or more of the latitudinal coils.
