Abstract

A detector detects the variation of resistance between fingers of a human'"'"'s hands which varies in response to his mental condition. When the mental condition is varied and the resistance between fingers is changed, the detector detects such resistance variation, which is then converted into an electric signal. This electric signal drive light emitting diodes (LEDs) or the like so that the user of this detector can realize his mental condition by watching the light. By further providing a lamp, an image film and a lens, the user can watch the image on the image film when light radiated from the lamp projects such image onto the lens. This detector is useful for meditation and mental training because the user can realize the variation of his mental condition by watching the light or image.

Claims

1. A detector for detecting resistance between fingers to determine the mental condition of a human, said detector comprising:

a. detecting means for detecting resistance between fingers of a human'"'"'s hand, said resistance varying in response to a variation of said human'"'"'s mental condition;

b. converting means for converting the variation of said resistance into an electric signal; and

c. visual indicator means which is turned on or off by said electric signal, said visual indicator means including a light source, a film and a lens which are disposed linearly in a direction toward the eyes of the human, said film having an arbitrary image thereon and being inserted at a position between said light source and said lens so that said image of film is lighted by said light source and then magnified by said lens, whereby said variation of human'"'"'s mental condition is indicated by visual inspection of said visual indicator means.

2. A detector for detecting resistance between fingers according to claim 1 wherein said indicator generates light in response to said electric signal, the brightness of light radiated from said indicator means being arbitrarily set or varied.

3. A detector for detecting resistance between fingers according to claim 1 wherein said indicator means is a light emitting diode (LED).

4. A detector for detecting resistance between fingers according to claim 1 further comprising comparator means for comparing a predetermined value with said resistance detected by said detecting means to thereby vary its output level, said output level of said comparator means corresponding to turn-on and turn-off operations of said indicator means,

whereby the output of said comparator means drives said light source to be turned on or off.

5. The detector of claim 1 wherein said converting means includes a comparator means for comparing said resistance to a preselected value.
