  • Patent number: 9318032
    Abstract: Systems and methods facilitating training in clinical procedures via mixed reality simulations are disclosed. Such a system can comprise a physical model and a virtual model of an anatomic region associated with the procedure, wherein the virtual model associates tissue types with locations in the physical model. The system can include a tracking component that tracks locations of at least one clinical instrument relative to the models, and an anatomic feedback component that can produce perceptible changes in the physical model based on the interaction between the instrument and virtual model. A clinical device interface can detect outputs of clinical devices like electrical signals, pressure or flow, wherein feedback to the physical model depends on the tracked position of a clinical device and output from the same or different clinical device. Another component can generate feedback effects to the clinical device. Aspects can simulate anesthesiology procedures like local nerve blockade.

  • Patent number: 9251739
    Abstract: A first display zone and a second display zone are displayed based on a first light source group, which corresponds to a first voltage data signal; and then the second display zone and a third display zone are displayed based on light for a second light source group, which corresponding to a second voltage data signal. The first light source group and the second light source group illuminate the display zones alternatively. Each display zone is fed with either a first data voltage signal or a second data voltage signal. While the first data voltage signal is updating each display zone in sequence, the second data voltage signal starts updating the first display zone when the first voltage signal is updating the third display zone.

  • Patent number: 9237337
    Abstract: A new beam deflection approach is provided for displaying images in autostereoscopic format. Conceptually, polarized light from a display is directed into specific viewing regions using a polarization-sensitive beam deflection sub-system that comprises, in exemplary embodiments, an active liquid crystal quarter-wave plate modulator and a passive cycloidal grating element, such as a diffractive waveplate. Specific embodiments may comprise an illumination system that both floods an LCD panel and creates a defined eye pupil region, from within which the display is viewable. Deflecting the pupil region between left and right eye positions in synchronization with displayed frame sequential stereo image data creates desirable autostereoscopic 3D viewing. Other embodiments employ a similar beam deflection sub-system in conjunction with a means of viewing subsets of pixels from different viewing positions, such as a parallax barrier or lenslet array, allowing freedom of head movement while maintaining stereo viewing.

  • Patent number: 9218673
    Abstract: A system and method for obtaining image information of features of a sample article using non-visible light is described. In one embodiment, a visible light filter is used on a camera to block out the visible light spectrum. The non-visible light is used to generate a colorless image of the sample article that includes the features of the sample article without the color information. Subsequent false color rendering of all or portions of the colorless image can be used to generate a visual representation of the sample article having a desired false color. The false color rendering of the sample article can be used in a catalog, brochure, website, advertisement, or any other publication or visual presentation.

  • Patent number: 9210322
    Abstract: High dynamic range 3D images are generated with relatively narrow dynamic range image sensors. Input frames of different views may be set to different exposure settings. Pixels in the input frames may be normalized to a common range of luminance levels. Disparity between normalized pixels in the input frames may be computed and interpolated. The pixels in the different input frames may be shifted to, or stay in, a common reference frame. The pre-normalized luminance levels of the pixels may be used to create high dynamic range pixels that make up one, two or more output frames of different views. Further, a modulated synopter with electronic mirrors is combined with a stereoscopic camera to capture monoscopic HDR, alternating monoscopic HDR and stereoscopic LDR images, or stereoscopic HDR images.
