  • 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.

  • Patent number: 11207143
    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.

  • Patent number: 11159735
    Abstract: An imaging system comprises a rolling shutter sensor that captures images of a scene, an illumination source that continuously illuminates the scene, a time-varying illumination source that illuminates the scene, and a processor that receives the images from the rolling shutter sensor. The rolling shutter sensor and the time-varying illumination source are operated synchronously to cause: on-cadence lines of the rolling shutter sensor to receive illumination from the continuously illuminating illumination source and a first amount of illumination from the time-varying illumination source; and off-cadence lines of the rolling shutter sensor to receive the illumination from the continuously illuminating illumination source and a second amount of illumination from the time-varying illumination source.

  • Publication number: 20210223553
    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.
