  • Publication number: 20230390021
    Abstract: New and innovative systems and methods for registration degradation correction for surgical procedures are disclosed. An example system includes a surgical marking pen including a first trackable target and a registration plate including a second trackable target. The system also includes a navigation camera and a processor configured to perform a pen registration that determines a transformation between a tip of the surgical marking pen and the first trackable target when the tip of the surgical marking pen is placed on the registration plate. The pen registration enables the processor to record virtual marks at locations of the pen tip that correspond to physical marks drawn by the pen. Locations of the virtual marks are later compared to images of the physical marks to correct any registration degradation by moving a surgical camera or robotic arm connected to the surgical camera.

  • Publication number: 20230363830
    Abstract: New and innovative systems and methods for auto-navigation in an integrated surgical navigation and visualization system are disclosed. An example system comprises: a single cart providing motility; a stereoscopic digital surgical microscope comprising a surgical visualization camera and a localizer; one or more computing devices (e.g., a single computing device powered by a single power connection) housing and jointly executing a surgical navigation module and a surgical visualization module, wherein the localizer is associated with the surgical navigation module, and wherein the surgical visualization camera is associated with the surgical visualization module; a single unified display; a processor; and memory.

  • Publication number: 20230240781
    Abstract: The present disclosure relates generally a hand-centric controller that provides a user (e.g., surgeon) with the ability to control a number of microscope movement controls, non-movement microscope controls, image and color controls, media controls, and hyperspectral controls without having to reach beyond the space surrounding the surgical tool being used or the space surrounding the surgeon's hands. In some embodiments, the hand-centric controller is a limited button (e.g., one, two, three buttons) controller. In other embodiments, the hand-centric controller is an extended hand-centric controller. The hand-centric controller may be configured to provide microscope movement (e.g., x-y axis movement, lock-to-target movement, yaw movement, physical focus movement, and gross general movement), non-movement microscope control (e.g., zoom, focus, autofocus, and white light), image and color controls (e.g., next image and previous image modes), media controls (e.g.

  • Patent number: 8257157
    Abstract: A system for video game physical interaction is provided for a host device with an associated interactive application by a plurality of physical building blocks each having at least one input connection point and one output connection point operable for connection to one or more of the remaining blocks. Detectable connection paths through the plurality of blocks allow determination of the shape of a structure created by the blocks and interfacing of the connection paths of the plurality of blocks to the host device creates an input to the interactive application. The application is then altered responsive to the connection paths.

  • Publication number: 20120002084
    Abstract: Disclosed herein are systems, apparatus, and methods for real-time image capture with variable density display, high resolution electronic zoom, and improved depth of field. The systems, apparatus, and methods used to view a target site include: at least one image sensor with an energy receiving surface having X pixels for producing one or more signals that correspond to the target site; at least one display for presenting N fields of view, wherein each field of view is comprised of at least one image produced by the signals; and an electronic zoom mechanism that can switch between N fields of view with little or no loss of resolution, wherein the first field of view is comprised of input from no more than X/N non-adjacent pixels and at least one zoom field of view is comprised of input from no more than X/N adjacent active pixels.

  • Patent number: 5726450
    Abstract: An unmanned integrated RES 12 integrates all of its components except the reflector 22 into a single console 30 that is positioned at the side of a road and has a CPU 36 that controls calibration, verification and data gathering. The RES's source 32 and receiver 34 are preferably stacked one on top of the other such that the IR beam 24 traverses a low and high path as it crosses the road 14. This allows the RES to detect both low and high ground clearance vehicles. To maintain the vehicle processing and identification throughput, the speed sensor 54 and ALPR 48,50 detect the passing vehicles at steep angles, approximately 20 to 35 degrees. In a preferred system, a manned control center 16 communicates with a large number of the unmanned integrated RES to download emissions data, perform remote diagnostics, and, if necessary, dispatch a technician to perform maintenance on a particular RES.
