Abstract
In the invention method and apparatus where electric signals are tapped as potentials in a physiologically produced electric field, a vector is determined which represents the instantaneous state of an electric dipole. In order to be able to substantially determine and interpret the movement of a vector, the time patten of the vector is also determined. This includes the determination of differential vectors, surfaces covered by the vector, loops forming the vector and projections of said loops in a plane.
Claims16
A process for processing electrical signals which are tapped by electrodes at a plurality of predetermined times in a physiologically produced electrical field, wherein said field is approximated by a dipole used as a model for said physiologically produced electrical field, comprising the steps of:
- measuring the signals tapped by said electrodes,
- computing a vector from the measured signals which represents the state of said dipole at said predetermined times,
- repeatedly computing said vector at a plurality of said predetermined times;
- and
- computing a value of a vector triangle derived from a said vector computed at a first said predetermined time and a said vector computed at a second said predetermined time.
The process according to claim 4, and the steps of repeatedly performing the steps of claim 37 to thereby determine a plurality of said surfaces for others of said periods of time, and comparing each said determined surface with at least one other of said plurality of determined surfaces.
Apparatus for processing electrical signals comprising:
- means for tapping signals to be processed from a physiologically produced electrical field,
- means for measuring said tapped signals;
- means for computing vectors from said measured tapped signals;
- and
- means for computing a value of a vector triangle derived from at least two of said vectors.
A process for processing electrical signals derived from physiological electrical activity of an organism, comprising the steps of:
- measuring potential values produced by said physiological electrical activity at predetermined locations on the organism producing said physiological electrical activity and at predetermined different times;
- computing vectors from said potential values at said predetermined different times;
- and
- computing value a vector triangle from a said vector computed at a first said predetermined time and a said vector computed at a said second predetermined time.
