Title:
SENSOR OUTPUT SIGNAL EVALUATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/129452
Kind Code:
A1
Abstract:
A sensor output signal evaluation system for objectively and quantitatively evaluating
the output signal of a sensor. An evaluation system for evaluating the output
signal of a sensor to measure the relaxation and contraction of a subject. The
system comprises an index signal generating unit (10) for generating an index signal
representing the index according to which the subject relaxes and contracts and
an output signal evaluating unit (20) for evaluating the approximation between the
output signal of the sensor and the index signal. The output signal evaluating unit
(20) has a maximum amplitude analyzing section (21) for evaluating the maximum amplitude
of the output signal during the contraction in response to the index signal, a
relaxation time analyzing section (22) for evaluating the output signal under
a predetermined threshold, and a contraction time analyzing section (23) for
evaluating the output signal over the predetermined threshold. The output signal
evaluating unit (20) evaluates the output signal by using at least one of the sections.
