Patent No. 4777529     Auditory subliminal programming system (Schultz, et al., Oct 11, 1988)

ASSIGNEE: R.M. Schultz & Associates, Inc., McHenry, IL

Abstract

An auditory subliminal programming system includes a subliminal message encoder that generates fixed frequency security tones and combines them with a subliminal message signal to produce an encoded subliminal message signal which is recorded on audio tape or the like. A corresponding subliminal decoder/mixer is connected as part of a user's conventional stereo system and receives as inputs an audio program selected by the user and the encoded subliminal message. The decoder/mixer filters the security tones, if present, from the subliminal message and combines the message signals with selected low frequency signals associated with enhanced relaxation and concentration to produce a composite auditory subliminal signal. The decoder/mixer combines the composite subliminal signal with the selected audio program signals to form composite signals only if it detects the presence of the security tones in the subliminal message signal. The decoder/mixer outputs the composite signal to the audio inputs of a conventional audio amplifier where it is amplified and broadcast by conventional audio speakers.

Notes:

SUMMARY OF THE INVENTION

The foregoing objects and attendant advantages are obtained by providing a subliminal decoder/mixer that receives audio program signals and subliminal message signals, automatically varies the amplitude of the subliminal message signals as a function of the amplitude of the audio program signals, and combines the signals into a composite signal in which only the audio program component is consciously audible.

With respect to another aspect of the invention, the decoder/mixer detects whether at least one predetermined security code is present in the subliminal message signals and prevents combination of the audio program signals and subliminal message signals unless such code is detected.

With respect to still another aspect of the invention, the decoder/mixer combines the subliminal message signal with at least one signal having selected frequency to produce composite subliminal signals.

A subliminal message encoder system is also provided that generates at least one predetermined security code, combines the code with subliminal message signals generated by an audio source and records the encoded subliminal message signals.

With respect to yet another aspect, the decoder/mixer is combined with an audio program source, a subliminal message source, an audio amplifier and audio speakers to provide an auditory subliminal programming system.

In another variation, the decoder/mixer is combined with an audio-video program source, a composite video signal modulator, and a television video display to provide an audio-video subliminal programming system.

What have been described are certain aspects of auditory subliminal programming systems which constitute presently preferred embodiments of the invention. It is understood that the foregoing description and accompanying illustrations are merely exemplary and are in no way intended to limit the scope of the invention, which is defined solely by the appended claims and their equivalents. Various changes and modifications to the preferred embodiments will be apparent to those skilled in the art. Such changes and modifications may include, but are not limited to: the use of different security arrangements such as pseudo-random codes and corresponding detectors; the addition or deletion of signal components from the composite output signals; the use of various different types of audio program source and subliminal message source equipment such as tape decks, speech synthesizers, live input, phonographs, and the like; and the use of different output devices such as headphones or the like. Moreover, various analog components of the preferred embodiment can be replaced by equivalent digital components and vice versa. Such changes and modifications can be made without departing from the spirit and scope of the invention. Accordingly it is intended that all such changes and modifications be covered by the appended claims and equivalents.
