  • Patent number: 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.

  • Patent number: 10341622
    Abstract: Smaller halftone tiles are implemented on a first modulator of a dual modulation projection system. This techniques uses multiple halftones per frame in the pre-modulator synchronized with a modified bit sequence in the primary modulator to effectively increase the number of levels provided by a given tile size in the halftone modulator. It addresses the issue of reduced contrast ratio at low light levels for small tile sizes and allows the use of smaller PSFs which reduce halo artifacts in the projected image and may be utilized in 3D projecting and viewing.
