Patent ID: 7142906

Claim:
A control device for a living body, using an optical measurement system for the living body, comprising: light incident means for applying lights of at least one wavelength in a visible-infrared region to a plurality of incident positions on a surface of the living body; light detection means for detecting lights obtained by allowing said applied lights to be transmitted through the living body at a plurality of detection positions on the surface of the living body; operation means for determining a type of output signal, based on an intensity of said transmitted light and pre-stored reference data by determining whether the intensity belongs to a distribution of the pre-stored reference data utilizing standard deviations and mean values of characteristics parameters of the intensity for an arbitrary time interval, and for outputting a signal indicative thereof as the type of output signal; memory means for storing the pre-stored reference data therein; and an external equipment for executing a functional operation according to the type of output signal from said operation means; wherein the incident positions of said light incident means and the detection positions of said light detection means are alternately disposed in a square lattice form, and middle points between the incident positions and the detection positions adjacent to one another are defined as measurement positions.
