  • Patent number: 9478245
    Abstract: The present techniques provide methods and systems for recording micro-holograms on a holographic disk using a plurality of counter-propagating light beams in parallel. The parallel counter-propagating light beams overlap to form interference patterns on a data layer and over multiple data tracks in the holographic disk. Rotating the disk enables the parallel recording of micro-holograms over multiple data tracks, thus reducing recording time. Further, the illumination pattern may include illuminated spots and non-illuminated regions, such that each illumination spot may cover a relatively small fraction of the data layer plane, possibly controlling the depth spread of the recorded micro-hologram. In some embodiments, data in the parallel signal beams may be retrieved from a master holographic disk or may be modulated into the parallel signal beams.

  • Patent number: 9222558
    Abstract: A geared infinitely variable transmission (GIVT) to provide a continuous output-to-input speed ratio from zero to a certain value is designed, and its working principle is illustrated. Crank-slider systems are used in the GIVT; the output-to-input speed ratio is changed with the crank length. Racks and pinions, controlled by planetary gear sets, are used to change the crank length when the cranks are rotating. One-way bearings rectify the output speeds from different crank-slider systems to obtain the output speed of the GIVT. Noncircular gears are used to minimize variations since the crank-slider systems can introduce variations of the instantaneous speed ratio. A direction control system is provided using planetary gear sets.
