Physics of Sound and Vibration: Effects On Human Electro-Dynamic Physiology

  Patent No. 5194008 Subliminal image modulation projection and detection system and method (Mohan, et al., Mar 16, 1993) ASSIGNEE: Spartanics, Ltd., Rolling Meadows, IL Abstract Weapon training simulation system including a computer operated video display scene whereon is projected a plurality of visual targets. The computer controls the display scene and the targets, whether stationary or moving, and processes data of a point of aim sensor apparatus associated with a weapon operated by a trainee. The sensor apparatus is sensitive to non-visible or subliminal modulated areas having a controlled contrast of brightness between the target scene and the targets. The sensor apparatus locates a specific subliminal modulated area and the computer determines the location of a target image on the display scene with respect to the sensor apparatus. Notes: BACKGROUND OF THE INVENTION This disclosure relates generally to

  Patent No. 5017143   Method and apparatus for producing subliminal images (Backus, et al., May 21, 1991) ASSIGNEE: Popeil Industries, Inc., Beverly Hills, CA Abstract A method and apparatus to produce more effective visual subliminal communications. Graphic and/or text images, presented for durations of less than a video frame, at organized rhythmic intervals, the rhythmic intervals intended to affect user receptivity, moods or behavior. Subliminal graphic images having translucent visual values locally dependent on background values in order to maintain desired levels of visual contrast. Notes: SUMMARY OF THE INVENTION The present invention is directed to a method and apparatus for producing more effective visual subliminal images. To that end, graphic and/or text images may be presented during a single video frame refresh, at organized rhythmic intervals intended to affect user receptivity, moods or behavio
