  • Patent number: 9168173
    Abstract: The apparatus and methods of the present invention in a broad aspect provide novel visualization platforms for performing enhanced visually directed procedures on target objects or tissues under low ambient light conditions. The visualization platforms can be included with or retro-fit to existing optical systems such as stereomicroscopes and include at least one high resolution photosensor capable of acquiring a plurality of optical views of the target object or tissue in at least one wavelength outside of the wavelengths of normal visible light. A resultant real-time high resolution video signal is transmitted from the photosensor to at least one high resolution video display that can be viewed by the apparatus or process operator.

  • Publication number: 20150221105
    Abstract: In some embodiments, an imaging system displays a multidimensional visualization of a surgical site. In some embodiments, the imaging system receives a selection corresponding to a portion of the displayed multidimensional visualization of the surgical site. At the selected portion of the multidimensional visualization, the imaging system displays a portion of a multidimensional reconstructed image which corresponds to the selected multidimensional visualization such that the displayed portion of the multidimensional reconstructed image is fused with the displayed multidimensional visualization.

  • Publication number: 20080279120
    Abstract: Systems and methods for an upgradeable and/or reconfigurable receiver are provided. In general, the present invention is directed to providing systems and methods for designing an electronic communication system having easy and cost effective upgradeable receiver systems and components including, for example, an amplifier and/or a filter. For example, a receiver may include a receiver front end that is configured so that at least one of the original conventional system components may be used along with one or more new system components to provide greater receiver sensitivity and/or selectivity. In various embodiments, portions of an upgradeable receiver system may be made as modular components that allow easy replacement for the upgradeable components which may include a signal amplifier and/or a signal filter. In various embodiments the receiver may be upgraded by replacing a conventional low noise amplifier (LNA) with a high temperature superconductor (HTS) filter and/or a cryo-cooled LNA.
