  • Patent number: 8985780
    Abstract: Disclosed is a liquid cooling system for use with MRI positioned video projectors to dissipate heat from the projector light source through liquid cooling. The system includes a heat sink body for mounting to the projector light source, the heat sink body constructed of a material to transfer heat away from the projector light. A remotely mounted motor-driven pump provides fluid circulation, the pump is constructed and/or mounted so as to not to be effected by the MRI magnetic field. The pump is coupled to the heat sink block by use of flexible tubing that is constructed and arranged to provide heat transfer to the environment thereby maintaining the projector light source temperature at a reduced level. A liquid reservoir is fluidly coupled to the pump intake for use in maintaining liquid levels at an optimum position.

  • Patent number: 6079829
    Abstract: An eye tracking device for analyzing motion of an individual's eye includes an image conveyor subsystem, an image receiving subsystem, and an image processing subsystem. The image conveyor subsystem includes a flexible fiber optic image guide having a first end spaced apart from a second end by a middle portion. The image guide first and second ends are in optical communication with each other. The image guide first end is positioned at a selected location with respect to an individual's eye. The second end is interfaced with the image receiving subsystem. The image receiving subsystem includes CCD video camera. The CCD video camera converts real-time analog eye images conveyed by the fiber optic image guide into digitized representations of the eye image. The light source utilized to form the reflected images is an independent source of illumination selected from infrared light or an equivalent portion of the non-visible spectrum. These digital representations are analyzed by the image processing subsystem.
