Abstract: A mechanical interface device having a number of three-dimensional tactile actuators is mounted to the touchscreen of an electronic device having a monitor, wherein a controller coupled to the touchscreen and to the monitor is operative to cause the monitor to display graphic images and/or text in response to engagement with or movement along the surface of the touchscreen by the three-dimensional tactile actuators.

Abstract: This invention relates to a Gatling-type machine gun simulated weapon system having a feeder de-linker which is capable of replicating malfunctions including a weapon jamming condition.

Abstract: A motion and vibration cuing system for use with a motion simulator provides vibratory, impulse, onset and sustained motion cuing, independently or simultaneously, by operation of a frame assembly capable of producing vibration and six degrees-of-freedom of motion in coordination with one or more motion seats, mounted to the frame assembly, which produce surge, sway, heave and roll motions.

Abstract: A motion seat for use in a vehicle motion simulator comprises a seat back, a seat pan, a first actuator coupled to a linkage assembly located on one side of the seat pan, a second actuator coupled to an identical linkage assembly on the other side of the seat pan, and a third actuator coupled to a linkage assembly on the aft end of the seat pan, wherein the first and second actuators are effective to independently produce roll right and roll left motion of the seat pan while collectively creating upward and downward heave motion of the seat pan and the third actuator is effective to create surge motion of the seat pan.

Abstract: A headphone sound system apparatus includes headphones and a sound system having an output line for the headphones for producing audio signals to the headphones. The sound recognition and interrupt system has the sound system output coupled thereto and to the headphones and has a housing which can be attached to the person, such as being clipped to a belt. The housing has a microphone mounted inside for picking up sounds extraneous to the sound system and a switching circuit mounted in the housing and connected to the microphone and which is actuated by the microphone between on and off positions responsive to signals of predetermined levels being generated by the microphone. The switching circuit disables the connection from the sound source so that a person wearing the headphones has the sound system turned down to thereby be able to hear the extraneous sound that actuated the switching circuit. The switching circuit is manually actuated to reconnect the sound source to the headphones.
