Abstract

A configurable system is used to evaluate stimulus sensitivity of a subject. An action channel provides a stimulus to the subject and a reaction channel receives a response from the subject. A signal pathway is connected to the action channel and to the reaction channel. A controller establishes loops within the signal pathway. Loop types include a transduction loop including the action channel and forming a path terminating in the signal pathway, and a channel loop including the action channel and terminating at a reference unit. Other possible loop types include an interface loop including the action channel, the reaction channel and the reference unit having an initial parameter value, and an adaptive loop including the action channel, the reaction channel and the reference unit whose parameter value is adapted based on the response from the subject. A method using the system is also described.

Claims24

Dependent claims

A system for evaluating stimulus sensitivity of a subject, comprising:

a first action channel configured to provide a first type stimulus to the subject;
a reaction channel configured to receive a response from the subject, wherein the action and reaction channels are implemented by means of actuators and sensors;
a signal pathway connected to the first action channel and to the reaction channel;
and
a controller adapted to establish at least one of:
a first transduction loop including the first action channel and forming a path terminating in the signal pathway,
a first channel loop including the first action channel forming a path through the signal pathway and terminating at a first reference unit,
an interface loop including the first action channel, the reaction channel and the first reference unit, the first reference unit having a first initial parameter value;
and
an adaptive loop including the first action channel, the reaction channel and the first reference unit, the first reference unit being adjusted from the first initial parameter value to a first adapted parameter value based on the response from the subject;
wherein the signal pathway is an automatically configurable signal pathway formed of switches that open and close per commands from the controller allowing for dynamically reconfiguring the system so that an action channel may become a reaction channel according to a pre-established program or to the subject responses in real or delayed time.

8 more elements

A system for improving sensitivity of a first sensory, reflex and/or motor mechanism of a subject, comprising:

a source of a facilitation signal for stimulating a second sensory, reflex and/or motor mechanism of the subject;
a sensor for measuring a physiological response of the first sensory, reflex and/or motor mechanism;
and
a controller providing for automatically selecting the source of the facilitation signal and automatically adjusting a level of the facilitation signal based on the measured physiological response and the evolution of the measured physiological response over a plurality of measurements;
wherein adjusting the level of the facilitation signal improves the sensitivity of the first sensory, reflex and/or motor mechanism of a subject due to Fulcrum Principle interactions;
wherein the controller is configured to:
a) first apply no facilitation signal;
b) acquire a first physiological response measurement while there is no facilitation signal;
c) increase a level of the facilitation signal;
d) acquire a next physiological response measurement;
e) detect an inflexion point of the next physiological response measurement;
f) following detection of the inflexion point, repeat the processes c), d) and e) until a predetermined maximum level of the facilitation signal is reached;
and
g) adjust the level of the facilitation signal by selection of a level of the facilitation signal providing a maximum physiological response that is increasing over a duration of acquisition thereof.
