ABSTRACT
The lateral flanks of each voltage impulse in an impulse electric field for the bioelectrical climatization of a room, i.e. the pulse rise and pulse drop, are selected with sufficiently different time spans that a bioelectrically active induction current is generated in a living organism staying in the room only for the shorter voltage change.

Description
~ 7~3~
State of the ~rt It is well-known that the psychologically favorable effects or natural conditions on the human organism are decisively influenced by the electrical conditions of the atmosphere. In the open air, the living organism is constantl~
exposed to the electrical forces of a constant electrostatic field as well as to the electrical oscillations of the atmos-phere. During the entire evolution of organisms on the earth, these atmospheric electrostatic conditions have exercised a decisive influence on every living creature. The organism has become accustomed to the natural atmospheric electricity ; and become adapted to it. Decreased intensity or complete absence of these atmospheric influences therefore represents a deficiency for every organism~
Living and working environments are more or less screened from the constant and-alternating electrostatic fields of the atmosphere depending on the physical characteristics of thé building materials used in their construction. In most cases working environments where individuals are required to perform at a high level o~ activity are constructed of rein-forced concrete which screens the persons working there from the electrostatic fields of the atmosphere. In vehicles, this screening effect is caused in many cases b,v the sheet -~ steel construction of the driver's cab.
It is known that the bioelectrical climate outdoors can be simulated in closed rooms by generating a constant electrostatic field between an electrode placed in the room and its walls and superposing on this field rectangular pulses with a frequency of approximately 10 H~. This simulation of natural atmospheric electrical conditions in closed rooms that are completely or partially shielded from the environment by , -- 1 --~L07~;3 3L~
Faraday screen effects permits a stimulating effect on the organism. This effect permanently and demonstrably influences in a desirably positive direction motor activity, oxygen intake and energy balance, cellular water and electrolyte balance, lipoil metabolism, circulation and peripheral blood supply, the immunobiological defensive system, reaction time, concentration and efficiency as well as subjective well-being. This favourable influencing action has been proved in many group tests.
In these tests and generally also in the practical application of devices producing constant electrostatic fields and superposed pulse fields in rooms, it was repeatedly observed that in addition to this positive, favourable influencing of the organism, certain persons reacted less to these fields than others. This fact was initially explained by the su~po-sition that constitutional differences exist in the reactions of those persons to atmospheric electrical fields. This prompted the attempt to improve the atmospheric electrical fields in such a manner that all persons exposed to them are ; 20 beneficially influenced by them to an equal degree.
Object of the Invention The objective of this invention was therefore to generate an appropriately modified atmospheric electrical field which exercises an invigorating, stimulating and favour-able influence on all living creatures and in particular on all persons with respect to the factors mentioned above.
Description of the Invention It was found that in a process for the generation of - bioclimatically active atmospheric electricity in rooms for which a periodically or an aperiodically alternating field ^ with voltage pulses in the range between approximately 0.1 "
~Q7~33~ ~
and 20 Hz in the correspondin~ room is generated, the problem described in detail above can be resolved according to the invention by selecting the span of one flank of each pulse to be small enough that a biologically stimulating displacement current is generated in a living organism in the room to be climatized with atmospheric electricity only through the momentary electrostatic change in this flank area, but not in the area of the oppositel~ directed pulse flank, in which the opposite electrostatic change is selected to be of relatively long duration.
Consequently according to the invention, flank rise and flank drop of each voltage pulse are selected with a time difference between them in such a manner that only one voltaae change causes a biologically stimulating displacement current in the organism while the other voltage change proceeds so slowly that it càuses only a small displacement current, which is not biologically stimulating. This surprising result can be explained by the relative difference of the oppositely directed induction currents, whereby it is assumed that this relative difference prevents a compensation of the effects in both directions, and thus prevents it in particular if the slower voltage change proceeds so slow~y that practically no stimulating displacement currents occur in the organism.
According to the invention this is the case when the flank span of the slower voltage change of each voltage pulse is at least lO0 microseconds and preferably lO00 microseconds.
The biologically stimulating effect occurs with shorter voltage changes.
It was found that upon maintenance of the afore-mentioned minimum time for the slow voltage change best resultscan be obtained if the slow voltage change is approximately 500 times longer than the fast voltage changes. For example, :' 53~
the flank rise of a 10 Hz impulse with a span of 10 micro-seconds as opposed to the flank drop of the pulse with 10 milliseconds in line with the above listed parameters has a biologically strong stimulating effect on all persons.
It must be emphasized that this beneficial effect cannot be realized if the volta~e pulses only have a sawtooth form as is usual for such pulses, but rather that only the above defined relative differences of the pulse flank spans with maintenance of minimum values for the broader flank lead to the desired result.` It was found that only in this case are the stimulating effects of the voltage changes of each pulse not able to neutralize each other. An accumulated stimulus of the individual voltage pulses results in the organism which are not compensated by opposite displacement currents due to the fact that a biologically stimulating displacement current is induced always in only one direction by the successive voltage pulses.
It was further found~that the stimulating effect through accumulating displacement currents does not depend on ~0 the direction of these currents so that either the rising or the falling flank of each pulse can be selected as being of shorter duration than the other flank.
.
It was further found tha-t optimal results are obtained when the impulse field according to the invention is superposed on a constant electrostatic field of approximately 50 to 500 volts/m. Surprisingly, however, it was ascertained that an impulse field according to the definition of this invention alone has positive stimulating effects on the organism, so that if economic considerations have priority, the use of a voltage pulse field alone according to the invention is indicated.

¦ The voltaye pulses are generated in known manner with an impulse generator which has, for example, an RC element for delaying the pulse rise or the pulse drop.
The invention is explained with the drawing.
Figures 1 and 2 show schematically a rectangular voltage pu:Lse and its effect in the organism according to the state of the art.
Figures 3 and 4 show a voltage pulse according to the invention and its effect in the organism and Figures 5 and 6 show preferred types of design of voltage pulses which are used in impulse fields according to the invention.
Figure 1 shows a rectangular pulse with two steep flanks which cause oppositely directed voltage changes. The ascending flank a generates a displacement current in a living or~anism which has the effect of producing in the body cells a charge impulse _ (Figure 2) with a specific polarity. Due to the equally steep descending flank c of the rectangular pulse according to Figure 1 a further displacement current
2~ is produeed and aceordingly also a eharge pulse d (Figure 2) which is opposite to the charge pulse _ and can neutralize its ef~ect. This is true also for the generally employed sawtooth pulse form as long as a defined prolongation of the span of one pulse flank is not effected according to the invention. As explained at the beginning, bioclimatically stimulating effects can therefore be realized only to a limited degree with rectangular pulses.
''~
Figure 3 shows a pulse form according to the invention with only one steep flank e. Flank f corresponding to the oppositely directed voltage change is delayed and has a span corresponding to time interval T, which is at least ten times, preferably five hundred times as long as the time interval or span of the ascending flank _ of the pulse.
With such a pu1se form, the body cells of the treated organism react with only one single charge pulse g (Figure 4), which is followed in a pulse sequence of 10 Hz by effective voltage changes with equal polarity only.
In Figures 1 and 3 pulses are shown which start from a zero potential (state of rest).
10Figures 5 and 7 show pulse forms which are set up on a positive or negative bias volta~e. The pulse forms according to Figures 5 and 7 display variations compared to those according to Figure 3 in that the maximal pulse voltage between the two flanks is kept constant for a certain interval of time. These pulse forms according to the invention produce optimal biologically stimulating effects. The span of the pulses is therefore preferably approximately twice as great as the span of flank h, 1, k (Figures 5 to 7) causing the slow or delayed voltage change.
20In case of a negative bias voltage according to Figure 6, the impulse voltage has a negative polarity.
As a variation from Figure 5, Figure 7 showns a delay ` of the ascending flank.
The following examples explain the invention.

was measured in the room.
An impulse field with a pulse frequency of 10 Hz was superposed on this constant electrostatic field in such a manner that the maximum impulse field voltage in the room measured approximately 5 volts/m. on the averaae.
In an experiment A, rectangular voltage pulses with a flank rise and a ~lank drop of 10 microseconds and a fre-quency of 10 Hz initially were periodically superposed on the constant electrostatic field.
In a further experiment B, the descending flank of each pulse was then delayed so that it had a span of 50 milliseconds. Each pulse drop thus had approximately half the span of the entire voltage pulse. Finally in an experiment C, - 15 thè atmospheric electrical field in the roo~ was completely disconnected so that the test persons were completely screened from every atmospheric electrical influence by the shielding action of the walls of the room that consisted of reinforced concrete.
During the experiments, 28 test persons were in the room, and they carried out for the most part sedentary activities requiring medium concentration and reaction on the - part of each individual person. It was ascertained that in experiment A as compared to experiment C approximately 23 persons displayed a marked increased reaction and concentra-tion ability of about 5% on the average, which was manifested not only in decreased fatigue but also in an improvement of the subjective well-being of these persons. Three persons displayed only a minor reaction and two persons almost no reaction at all to the atmospheric electrical stimuli.

With experiment B it could be proved that all persons without exception were positively influenced with respect to their concentration and reactions by the atmospheric electrical stimuli and displayed an increase in efficiency of approx-imatelyfl2 to 15%.
Example 2 An impulse field system according to the invention was installed in a vehicle drivina simulator for which the positive electrode measuring lO x 30 cm. was placed above the driver's seat. The applied constant voltage measured 180 volts and that of the impulse field superposed on the constant field 20 volts.
The field intensity between electrode and carriage as measured at head level at the driver's seat amounted to approximately 100 volts/m. in the constant field and to S volts/m. in the impulse field. Twelve persons were tested here as in Example l under conditions A, B and C with e~ual values for frequency and flank span. Each of the drivers (test persons) was subjected to 4 individual tests, 2 of each were conducted with and 2 without the described electrical fields. With the field action in experiment B, i.e. under the influence of an impulse field corresponding to this invention, a more uniform and stronger activation of the driver was occasioned by the atmos-pheric electrical stimulus than in experiment A. In particular, ; measurements made in experiment B showed a 12% increase in concentration, likewise a 12% increase in driving performance, a reduction in reaction time of 5 to 20% and a significantly more regular driving behavior in comparison with experiment C
(without field conditions). These results produce proof that the measure according to the invention makes a considerable

With such a pu1se form, the body cells of the treated organism react with only one single charge pulse g (Figure 4), which is followed in a pulse sequence of 10 Hz by effective voltage changes with equal polarity only.
