In one aspect, a method comprises: obtaining a target environment model of the target environment; modifying the target environment model of the target environment to generate an obfuscated environment model of an obfuscated environment that represents an obfuscation of the target environment; obtaining, from each of a plurality of users, one or more obfuscated environment trajectories that represent interaction of the user with the obfuscated environment through the corresponding obfuscated environment simulation; mapping each of the obfuscated environment trajectories to a corresponding target environment trajectory; and training the action selection system on the target environment trajectories.

Abstract: A system for unmanned aircraft system (UAS) testing which incorporates a UAS flight control system and an optionally piloted vehicle (OPV) carrying the UAS flight control system. The OPV has an OPV flight control system and a flight control interpreter (FCI) which receives input from the UAS flight control system representing control parameters for a flight profile of the UAS. The FCI provides status commands as an output to the OPV flight control system to replicate the flight profile. These status commands are selected from the group consisting of data regarding attitude, vertical navigation, lateral navigation, turn rate, velocity and engine operations. The OPV flight control system includes a pilot override for emergency, flight safety or other contingencies allowing an on board pilot to assume control of the OPV.

Abstract: A network connects stations in a distributed physics based simulation system. When the simulation detects that a weapon, especially a missile or directed energy beam, is engaging a target vehicle, one physics station determines damage status of the target vehicle. The detonation or strike of the weapon is applied to a model of the vehicle composed of pieces each made up of a number of parts. Where the damage to a piece of the vehicle exceeds a predetermined threshold, the piece is removed from the vehicle, and where a predetermined maximum damage is reached for the vehicle, the vehicle is considered destroyed. The damage assessment from the weapon is made using raytracing in a physics engine that is also used to control movement of virtual objects in the simulation according to rules of physics of the physics engine.

Abstract: In an embodiment, input data is received from a user and reference data is calculated based on an original simulation state. An adjustment amount is determined based on the difference between the input data and the reference data. An event value is generated via a probability function, and the event value is adjusted by the adjustment amount into an adjusted event value. A next simulation state is then determined based on the adjusted event value, and the next simulation state is presented to a user. In an embodiment, the adjustment amount is proportional to the difference. In this way, direct and realistic feedback to the user is provided via the simulation state, which positively reinforces correct behavior and negatively reinforces incorrect behavior, more so than does an unadjusted simulation.

Abstract: An aircraft crosswind training simulator has a fixed-pitch cockpit rotatably mounted atop a platform. Rotation of the cockpit is controlled by motor controllers that are responsive to movement of the cockpit's steering control. A rotation sensor detects rotation of the cockpit and communicates with a motor controller that controls the direction and speed of a motor mounted to the platform. The motor is engaged with a drive wheel that drives the platform laterally across the floor in response to rotation of the cockpit that is detected by the rotation sensor. An instructor input switch manipulates the motor controllers to introduce additional forces to the rotation of the cockpit and/or additional forces to the lateral movement of the platform, simulating external forces present during crosswind conditions.

Abstract: An AutoTrim function automatically adjusts the trim of the elevator of a simulated aircraft to compensate for pitching moments that are not caused by a user affirmatively controlling the elevator. A flight simulator program determines a sum of the pitching moments acting on the simulated aircraft, excluding the user setting of the elevator. The sum of the longitudinal pitching moments is then set equal to zero to solve for a desired position for setting the AutoTrim control. A time lag is applied in setting the AutoTrim control to the desired position, to provide greater realism. Use of the AutoTrim control provides enhanced control authority to the user in controlling the longitudinal pitch of the aircraft. The AutoTrim control functionality is stopped as the angle of attack of the aircraft approaches a stall condition, but resumes when the plane is flying in a substantially safer flight condition.

Abstract: Disclosed is a video game apparatus which enhances a realism of a ski-jumping competition by displaying a changing wind direction as a prediction guide. In the video game apparatus, a wind data operating unit obtains a wind direction and a wind speed. The amount of change in the wind direction changes in the form of a sine curve, and the wind speed also changes in the form of a sine curve. A wind data display control unit displays a wind direction guide and a wind speed guide on a screen. The wind direction guide uses an arrow, and the wind speed guide is displayed by the thickness of the arrow. A run-up control unit allows a competitor of the game to start the run-up when a first left button is operated. An attitude control unit controls the flight distance of ski-jumping by controlling the height of the competitor with the influence of wind direction and wind speed, and the flight direction of the competitor obtained from corrected conditions by the leftward and rightward keys.

Another sheet is mounted behind the first sheet and includes multiple graphics that are intended, in their stationary position, to be aligned with the cutouts of the first graphics to complete a picture or image. The first sheet is rotatably mounted and weighted to always assume the same orientation. The second sheet is also rotatably mounted within the housing and is connected to the drive mechanism.
