HYPERACUITY SYSTEM AND METHODS FOR REAL TIME AND ANALOG DETECTION AND KINEMATIC STATE TRACKING

LAMINA SYSTEMS, INC., Co...

1. A method of calculating a position of a feature of an object at hyperacuity accuracy, the method comprising:receiving output signals from a plurality of sensors, wherein the plurality of sensors:
are configured in an array;
have overlapping spatial response profiles, wherein for each of the plurality of sensors, the spatial response profile is non-linear and is axio-symmetric about a respective center of the sensor; and
produce the output signals based on the spatial response profiles;
generating logarithmically amplified output signals by applying logarithmic amplification to each output signal;
multiplying the amplified output signals by predefined constants that are based on:
distances between each of the plurality of sensors and a physical origin of the array; and
a rate of response decay of each of the plurality of sensors; and
determining coordinates of the position of the feature with respect to the physical origin of the array by summing the logarithmically amplified output signals.

1. A method of calculating a position of a feature of an object at hyperacuity accuracy, the method comprising:receiving a plurality of output signals from a plurality of sensors, wherein:
the plurality of sensors have overlapping spatial response profiles that are non-linear and axio-symmetric about respective centers of each of the plurality of sensors; and
the plurality of sensors produce the plurality of output signals based on the overlapping spatial response profiles;
generating first weighted signals by weighting each of the plurality of output signals with respective first sinusoidal weights;
generating second weighted signals by weighting each of the plurality of output signals with respective second sinusoidal weights;
generating a first orthogonal resultant signal, wherein the first orthogonal resultant signal comprises a sum of the first weighted signals;
generating a second orthogonal resultant signal, wherein the second orthogonal resultant signal comprises a sum of the second weighted signals; and
determining the position of the feature using the first orthogonal resultant signal and the second orthogonal resultant signal.
