Patent ID: 8652012

Claim:
A gyroscopic wrist exerciser having a transparent plastic housing and a gyroscopic rotor mounted on an axle rotating on a primary axis of rotation about the axle, wherein ends of the axle are extended into a circumferential housing groove disposed on an inside surface of the transparent plastic housing, wherein the ends of the axle rotate in a secondary axis of rotation about the circumferential groove to provide precession of the gyroscopic rotor, wherein the gyroscopic wrist exerciser is configured for color changing and comprises: a. a permanent magnet cooperating with a coil to produce an electric current, wherein the electric current is proportional to the speed of the rotor; b. a microcontroller connected to and powered by the coil, wherein the microcontroller has three separate outputs, namely a first output, a second output and a third output which receive degrees of voltage depending upon an input voltage from the coil; c. a first LED chip connected to the microcontroller at the first output; d. a second LED chip connected to the microcontroller at the second output; e. a third LED chip connected to the microcontroller at the third output, wherein the microcontroller is configured to produce a varied output depending upon the input voltage from the coil: f. wherein at a minimum voltage the first chip activates producing a first LED maximum output, wherein the second LED chip begins at a second LED lower range shut off output, wherein the third LED chip begins at a third LED lower range shut off of no light intensity; g. wherein an increase of rotational speed and voltage to a lower middle voltage range provides a drop in intensity of the first LED chip, and increasing the intensity of the second LED chip and a minor increase in the intensity of the third LED chip; h. wherein a middle voltage range produces a first LED lower output at the first LED chip, wherein the second LED chip proceeds to a second LED midrange maximum output, while the third LED chip moves to a third LED medium range output; i. wherein an upper middle voltage range produces decreasing intensity of the first chip, decreasing intensity of the second chip and increasing intensity of the third chip; and j. wherein a voltage maximum produces a first LED upper range shut off output of the first LED chip, a second LED upper range shut off output from the second LED chip, and a third LED upper range maximum output from the third LED chip.
