Patent ID: 10379435

Abstract:
A rotatable stroboscopic animation device with a rotatable base portion and at least one light source. An angular-velocity-dependent flashing system flashes the at least one light source according to a predetermined flash mode dependent on the angular velocity of the base portion to produce coherent, automatic stroboscopic animation of images retained by the base portion. The flashing system can comprise an angular velocity determination system in cooperation with an illumination system. Angular velocity can be determined by an orienting system, such as a compass, in combination with a sampling system, a gyroscope, or a rotational sensor. A flash mode selection mechanism, which can be manual or automatic, permits a selection of a flash mode from among a plurality of flash modes. A manual flash mode selection mechanism can be formed by relatively pivotable upper and lower disks of the base portion. Animation disks can have indications of predetermined flash modes.
