    Abstract: Objects and their placement within a particular scene may be characterized using structured light with no or minimal manual intervention or calibration to the scene. The structured light pattern may be rendered with visible light, yet imperceptible to users, by generating a set of opposing excursions in one or more image properties for durations which are shorter than the integration time of the human eye. A set of assumptions and ongoing testing of those assumptions against physical objects identified within the environment allows characterization of the scene and the objects therein.

For enhanced viewing there is a button spring release lens attachment enabling user to view the projected images and interactive adventure mode in another aspect. The interactive mode allows the user manipulation of the projected vehicle in real time within the display. The nightlight is also equipped with a pair of 3-D glasses. The panic mode feature allows the user to illuminate the body of the nightlight in the event that a user needs all the lights illuminated quickly, adding comfort.

  • Patent number: 8092027
    Abstract: A portable electronic device with micro-projecting module includes a shell body, a micro-projecting module, a heat-conducting plate and a supporting stand. The shell body has a front lateral plate and a bottom lateral plate adjoining the front lateral plate. The front lateral plate has a front through hole, while the bottom lateral plate has a bottom through hole. The micro-projecting module is arranged in the shell body and has a lens exposing to an outside of the shell body from the front through hole. The heat-conducting plate is arranged in the shell body and is positioned between the micro-projecting module and the bottom through hole. In the meantime, the heat-conducting plate has a heat-absorbing face contacting the micro-projecting module and a heat-dissipating face abutted against the bottom through hole.

  • Patent number: 8073531
    Abstract: The present invention is a Miniature Vein Enhancer that includes a Miniature Projection Head. The Miniature Projection Head may be operated in one of three modes, AFM, DBM, and RTM. The Miniature Projection Head of the present invention projects an image of the veins of a patient, which aids the practitioner in pinpointing a vein for an intravenous drip, blood test, and the like. The Miniature projection head may have a cavity for a power source or it may have a power source located in a body portion of the Miniature Vein Enhancer. The Miniature Vein Enhancer may be attached to one of several improved needle protectors, or the Miniature Vein Enhancer may be attached to a body similar to a flashlight for hand held use. The Miniature Vein Enhancer of the present invention may also be attached to a magnifying glass, a flat panel display, and the like.
