Abstract
Abstract A compact environmental modification apparatus and method are disclosed for selectively supplementing predetermined characteristics of substantially enclosed environments, for example in rooms, and/or vehicles, to thereby more nearly simulate desirable naturally occurring environmental conditions, and to enhance the performance and/or physical and mental well-being of occupants of the enclosed environment. The apparatus preferably includes operator regulated negative ion and electrostatic field generators, as well as an electrostatic field pulsator for establishing, and regulating the frequency of, pulsations in the electrostatic field, and the apparatus may be incorporated with a system for environmental modification which includes filters for filtering of air circulated through the enclosed environment. The apparatus is particularly well adapted for convenient and advantageous location in vehicles, including, but not limited to, ground craft, aircraft, spacecraft, marine craft. and the like, and/or for location within helmets which operators and/or occupants thereof may be required to wear.
