  • Patent number: 10206749
    Abstract: Devices, systems and methods for detecting a position of an object with a robot surgical system having an articulable, separable camera stand. The surgical robot system may include a robot having a robot base with a robot arm and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, other objects, or any combination thereof, may be tracked via active and/or passive tracking markers. A camera, such as an infrared camera, a bifocal camera or a stereophotogrammetric infrared camera, is mounted on a separable camera stand and is able to detect the tracking markers when in use. Using the camera, the robot determines a position of the object from the tracking markers, which may be a three-dimensional position of the object or the markers. When convenient, the camera base may be assembled into the robot base, e.g., by sliding the camera base into the robot.

  • Publication number: 20160162421
    Abstract: A method of reducing power consumption in a computing platform is disclosed. An endpoint-device that is coupled to the computing platform includes a first data buffer and a second data buffer. The first data buffer buffers outgoing data to be transmitted to an external device via a first communications medium. The second data buffer buffers incoming data received from the external device via the first communications medium. At least one of the first or second data buffers may selectively communicate with the computing platform, via a second communications medium, during an active window of the other data buffer. The active window may be requested by the first and/or second data buffers based, at least in part, on a system idle signal. For some embodiments, the first communications medium is an Ethernet link. Further, for some embodiments, the second communications medium is a Peripheral Component Interconnect Express (PCIe) link.
