| titleOfInvention | Fluid suspended self-rotating body and method |
| abstract | In a display device where a moving object is immersed in a fluid filling a transparent sealed, vessel (72) and is rotated by an internal electrical mechanism that derives it power from a photo cell (128) and its counter torque from an internal compass (140), the index of refraction of the fluid is adjusted by addition of water to match the index of refraction of the vessel material. The formula of the fluid is also tailored to minimize absorption of ambient moisture into the vessel. In one embodiment of the electrical spinning mechanism, the magnet acts both as a biasing compass and as a magnetic field generator for the motor. In a second embodiment of the spinning mechanism, the stator is constituted by a multipole ring-shaped magnet (120) that does not interfere with the operation of the biasing compass magnet (140). Multiple windings in the electrical spinning mechanism are energized through a split-ring and brush commutator (92) that use the mechanism shaft (122) as conductor. |
