Environmental control using a chaotic function
First Claim
1. A method of environmental control, comprising steps of:
- automatically producing a chaotic variation of a controlled characteristic of a first environmental condition in a space to be utilized by one or more occupants, during a period of time less than a day, at least in part in accordance with a first chaotic function that produces one of quad-stable results or unstable results with attractors in the chaotically varied controlled characteristic of the first environmental condition; and
automatically producing a chaotic variation of a controlled characteristic of a second environmental condition in the space, different from the first environmental condition, during a period of time less than a day when the space is occupied, at least in part in accordance with a second chaotic function that produces one of quad-stable results or unstable results with attractors in the chaotically varied controlled characteristic of the second environmental condition, wherein;
the first environmental condition is artificial visible illumination within the space; and
the second environmental condition is not directly related to visible illumination within the space.

Abstract
One or more controlled environmental conditions have a characteristic thereof that varies over time at least in part in accordance with a chaotic function. Variable control, for example, may control one or more characteristics of visible lighting of the environmentally controlled space. Examples of lighting characteristics that may be controlled in such a manner include spectral content, intensity, color temperature, chromaticity difference or Delta_uv, and polarization. In addition or instead, one or more characteristics of the atmosphere in the controlled environment may be controlled based on a chaotic function. Examples of atmospheric characteristics that may be controlled in such a manner include temperature, humidity, air pressure, ionization, electromagnetic fields, precipitation, visibility, wind, smell and chemical composition. A sound system may also provide a chaotic component to the environment in the environmentally controlled space.

17. A method of environmental control, comprising steps of:
-
automatically producing a chaotic variation of a controlled characteristic of a first environmental condition in a space to be utilized by one or more occupants, during a period of time less than a day, at least in part in accordance with a first chaotic function; and automatically producing a chaotic variation of a controlled characteristic of a second environmental condition in the space, different from the first environmental condition, over a period of time less than a day, at least in part in accordance with a second chaotic function, wherein; the step of chaotically varying the controlled characteristic of the first environmental condition comprises varying the controlled characteristic of the first environmental condition in accordance with a combination of a first nominal function and the first chaotic function; the step of chaotically varying the controlled characteristic of the second environmental condition comprises varying the controlled characteristic of the second environmental condition in accordance with a combination of a second nominal function and the second chaotic function; when the space is occupied, variations of the controlled characteristics of the environmental conditions impact perception of the space by a human occupant of the space; and the second nominal function is different from the first nominal function. - View Dependent Claims (18)

19. An environmental control system, comprising:
-
a first environmental conditioner configured to control of a characteristic of a first environmental condition in a space to be utilized by one or more occupants, so as to automatically chaotically vary the controlled characteristic of the first environmental condition during a period of time less than a day, at least in part in accordance with a first chaotic function that produces one of quad-stable results or unstable results with attractors in the chaotically varied controlled characteristic of the first environmental condition, the first environmental conditioner comprising a controlled lighting device for illuminating the space; and a second environmental conditioner configured to control of a characteristic of a second environmental condition in the space different from the first environmental condition, so as to automatically chaotically vary the controlled characteristic of the second environmental condition during a period of time less than a day when the space is occupied, at least in part in accordance with a second chaotic function that produces one of quad-stable results or unstable results with attractors in the chaotically varied controlled characteristic of the second environmental condition. - View Dependent Claims (20, 21, 22, 23)

24. An environmental control system, comprising:
-
a source of visible artificial light configured to illuminate a space to be utilized by one or more occupants; a conditioner configured to establish another environmental condition within the space not directly related to illumination of the space; a controller coupled to control operation of the source of visible artificial light and the at least one conditioner, wherein the controller is configured to; control operation of the source of visible artificial light so as to automatically produce chaotic variation of a controlled characteristic of visible artificial light emitted from the source into the space during a period of time less than a day, at least in part in accordance with a first function including a first chaotic function component that produces one of quad-stable results or unstable results with attractors in the chaotically varied controlled characteristic of the visible artificial light, and control operation of the conditioner so as to automatically produce chaotic variation of a controlled characteristic of the other environmental condition within the space during a period of time less than a day when the space is occupied, at least in part in accordance with a second function including a second chaotic function component that produces one of quad-stable results or unstable results with attractors in the chaotically varied controlled characteristic of the other environmental condition, wherein the second function is different from the first function. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

34. An environmental control system, comprising:
-
a first environmental conditioner configured to control of a characteristic of a first environmental condition in a space to be utilized by one or more occupants, so as to chaotically vary the controlled characteristic of the first environmental condition over a period of time less than a day, at least in part in accordance with a first chaotic function; and a second environmental conditioner configured to control of a characteristic of a second environmental condition in the space different from the first environmental condition, so as to chaotically vary the controlled characteristic of the second environmental condition over a period of time less than a day, at least in part in accordance with a second chaotic function, wherein; the first environmental conditioner is further configured to enable control such that the chaotic variation of the controlled characteristic of the first environmental condition comprises varying the controlled characteristic of the first environmental condition in accordance with a combination of a first nominal function and the first chaotic function; the second environmental condition is further configured to enable control such that the chaotic variation of the controlled characteristic of the second environmental condition comprises varying the controlled characteristic of the second environmental condition in accordance with a combination of a second nominal function and the second chaotic function; when the space is occupied, variations of the controlled characteristics of the environmental conditions impact perception of the space by a human occupant of the space; and the second nominal function is different from the first nominal function. - View Dependent Claims (35, 36, 37, 38)
