  • Patent number: 11513358
    Abstract: Compact and low mass augmented and fully virtual head mounted display designs are disclosed. The disclosed displays employ a display located between the eye and the main optical element of the head mounted display. These designs additionally afford the ability to support augmented reality displays because the user can see both the virtual image from the display and the real world if desired. The designs use semi-transparent displays where either the display emits circularly polarized light or the displays which emits light from one surface or the view of the display directly from the eye is obscured.

  • Patent number: 11452489
    Abstract: A radiation finder tool assists in locating tissue of interest within a patient. The radiation finder tool includes a body and a plurality of radiation detectors. The body has a distal end, a proximal end. A lengthwise axis of the radiation finder tool extends between the proximal end and the distal end of the body. The plurality of radiation detectors is oriented serially along the lengthwise axis, e.g., stacked one after the other along the lengthwise axis. Each radiation detector of the plurality of radiation detectors has a different field of view for radiation detected by that radiation detector. Each field of view of the plurality of radiation detectors has the lengthwise axis at its center.

  • Publication number: 20220095903
    Abstract: A system directs an imaging device to continuously capture visible light and fluorescence illumination from a surgical area. The system generates a visible light image stream based on the captured visible light and a fluorescence image stream based on the captured fluorescence illumination. The system operates in a first display mode by directing a display device to display a first video stream based on a first set of at least one of the visible light image stream and the fluorescence image stream. In response to detecting an event that occurs within the surgical area, the system switches from operating in the first display mode to operating in a second display mode by directing the display device to display a second video stream based on a second set of at least one of the visible light image stream and the fluorescence image stream, the first Instructions set being different than the second set.

  • Publication number: 20220087758
    Abstract: Systems and methods for minimally invasive computer-assisted telesurgery are described. A computer-assisted teleoperated surgery system includes a teleoperated instrument actuation pod. The surgical instrument actuation pod includes a plurality of linear actuators arranged around a surgical instrument. The linear actuators engage with actuator engagement members on the instrument and so drive movable parts on the instrument. The actuation pod is mounted on a teleoperated manipulator. Instrument pod mass is close to the teleoperated manipulator to minimize the pod's inertia, momentum, and gravity effects on the manipulator.

  • Publication number: 20220006938
    Abstract: An imaging system and method includes a rolling shutter sensor that captures a plurality of images of a scene, a time-varying illumination source that illuminates the scene, and a processor that receives the plurality of images from the rolling shutter sensor and separates the plurality of images into a plurality of feeds. Each of the plurality of images is captured as a series of lines. The rolling shutter sensor and the time-varying illumination source are operated synchronously to cause a plurality of on-cadence lines of the rolling shutter sensor to receive more illumination from the time-varying illumination source than a plurality of off-cadence lines of the rolling shutter sensor. Each of the plurality of feeds has a different contribution of the time-varying illumination source to an overall illumination of the scene.
