  • Patent number: 8619167
    Abstract: A method for displaying or capturing an image comprises directing an illumination beam onto a mirror of a highly resonant, mirror-mount system and applying a drive signal to a transducer to deflect the mirror. In this method, the drive signal has a pulse frequency approaching a resonance frequency of the mirror-mount system. The method further comprises reflecting the illumination beam off the mirror so that the illumination beam scans through an area where the image is to be displayed or captured, and, addressing each pixel of the image in synchronicity with the drive signal to display or capture the image.

  • Publication number: 20060012562
    Abstract: A method, apparatus, and system for tracking movement of a device are described. The method includes steps of implementing a first tracking subsystem for tracking positions of a device against a surface, determining whether to implement a second tracking subsystem for tracking positions of the device against the surface, capturing data corresponding to a location on the surface, and determining a position of the device against the surface based on the captured data. The position of the device can then be transmitted to a host computer and used in an application program. The first and second tracking subsystems may be a relative and an absolute tracking subsystem respectively.
