DETAILED DESCRIPTIONS OF SOME PREFERRED EMBODIMENTS
Disclosed herein are methods and apparatus that may be used to detect microvariations in a biologic living organism, and generate a sequence of changes perceptible through the human senses (e.g., sight, sound, temperature, humidity, etc.) in the environment surrounding that organism or a human participant based on those microvariations. As used herein, the term "biologic living organism" means a plant or a non-human animal. The term "microvariations", as used in this document, shall be construed to include any measurable minute variation within a living organism. Such microvariations can be in electrical impedance, dielectric constant, chemical concentrations, electrochemical potential, electrochemical current, mechanical tension, force, pressure, optical transmisivity, optical reflectivity, reflected or transmitted chromatic value, magnetic or electrical permeability, etc. The term "microvariations" does not mean bio-frequency spectrum signals emanating from the living organism.
One embodiment of the disclosed invention has been found effective in detecting microvariations in a living organism and generating pleasing melodies based on these microvariations. Living organisms, including plants, are believed capable of varying their internal bio-chemical and bio-electric state as a consequence of external situations. Plants are, therefore, capable of some sort of rudimentary "feelings".
FIG. 1 shows a block diagram of the apparatus of the present invention. Signal conditioning electronics 1 connects to living organism 2 through interface 3. Microvariations within organism 2 produce analog signal 4 which feeds signal conditioning electronics 1. In some preferred embodiments, excitation electronics 5 applies an excitation signal 15 to organism 2, and microvariations in the response of organism 2 to excitation signal 15 are measured through analog signal 4. In preferred embodiments utilizing purely passive measurement (such as measurement of microvariations in electrochemical offset voltage Vo produced by organism 1), no excitation signal is needed and thus excitation electronics 5 are not employed.
In a preferred embodiment, conditioning electronics 1 provides amplification, level shifting, and filtering to best utilize...
