Abstract
A biorhythmic cycle indicator having three, sine-wave-contoured plates that slidingly overlay a backing plate that has a calendar strip. The plate contours and the calendar register to provide a graphic representation of a person's biorhythmic cycle. The contours of the sliding plates are illuminated to accent the component cycles.
Claims1
A biorhythmic device comprising:
- a. a back plate having a front surface that displays indicia depicting a time period divided into days with said days being represented by spaces defined by spaced vertical lines, said indicia further comprising a horizontal line dividing the spaces into upper and lower regions;
- b. three sliding members, each comprising a translucent sheet having a lower edge and an upper edge, said upper edge having a sine wave contour of a different biorhythmic cycle;
- said sliding members overlay each other and the back plate such that the sine wave contours overlay the time period indicia, said sliding members are slidable, in relation to the other members and the back plate, in the direction of the horizontal line, thus providing means to define positive and negative regions and transition points on the cycles;
- and
- c. means for edge illuminating the sine wave contours comprising:
- a light source on the back plate,
- means, on the sliding plates, for introducing light from the light source into the sliding member, and
- means, on the upper edge, for emitting the light introduced into the sliding member.
