DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to systems and methods for modification of biorhythmic activity.
BACKGROUND OF THE INVENTION
Various techniques and systems have been proposed for modification of biorhythmic activity. The following patents are believed to represent the state of the prior art: U.S. Pat. No. 5,267,942 to Saperston, entitled Method For Influencing Physiological Processes Through Physiologically Interactive Simuli. U.S. Pat. No. 5,076,281 to Gavish, the present inventor, entitled Device and Method for Effecting Rhythmic Body Activity. Further relevant prior art appears in the References Cited listings of the aforesaid patents and in the Background sections thereof. U.S. Pat. No. 5,423,328 also to Gavish describes a monitoring device which is particularly suitable for use in the present invention. The disclosures of all of these patents are hereby incorporated by reference.
SUMMARY OF THE INVENTION
The present invention seeks to provide an improvement to the systems and techniques of the prior art.
There is thus provided in accordance with a preferred embodiment of the present invention a system for modifying naturally occurring biorhythmic activity including a monitor for analyzing biorhythmic activity of a user, a biorhythmic activity modifier for providing to the user a stimulus input which is operative to change at least one aspect of the biorhythmic activity of the user, and a driver operative to control the operation of the biorhythmic activity modifier, so as to change at least one non-frequency characteristic of the input to the user, in response to changes in the biorhythmic activity of the user during operation of the modifier.
Preferably, the driver is operative to change at least one non-frequency characteristic of the input to the user in response to at least one corresponding change in a non-frequency characteristic of the biorhythmic activity of the user during operation of the modifier.
In accordance with a preferred embodiment of the present invention the non-frequency characteristic of the input to the user forms part of a recurrent pattern.
Preferably, the driver is also responsive to selectable operator commands for governing the manner in which the non-frequency characteristic of the input to the user is changed.
In accordance with a preferred embodiment of the present invention the non-frequency characteristic includes the relationship of at least two components of a generally recurrent pattern.
Preferably the selectable operator commands are operative to select at least one of a plurality of relationships between at least two characteristics of a generally recurrent pattern of the input to the user which are modified.
In accordance with a preferred embodiment of the present invention the modifier is also responsive to the time relationship between a generally recurrent pattern in the biorhythmic activity of the user and a generally recurrent pattern in the input to the user.
Preferably, the driver is operative in an at least partially predetermined manner.
In accordance with a preferred embodiment of the present invention the system also comprises a shift detector receiving inputs from the monitor and the modifier and providing a shift correction output to the modifier.
Preferably, the shift detector also receives an input from the driver and is responsive thereto for providing the shift correction output to the modifier.
In accordance with a preferred embodiment of the present invention the input from the driver includes operator command determined instructions.
Preferably, the shift correction output is provided in response to the time relationship between the onsets of biorhythmic activity signals and stimulus inputs to the user.
In accordance with a preferred embodiment of the present invention the shift correction output is provided by delaying the onset of stimulus inputs to the user.
Preferably the shift correction output is provided by moving up the onset of stimulus inputs to the user.
In accordance with a preferred embodiment of the pr
