    Abstract: Methods and systems for providing feedback during a medical procedure. The 3D position and orientation of a tracked tool are determined, relative to a site of the medical procedure, based on tracking information received from a tracking system. The 3D position and orientation are mapped to a common coordinate space, to determine the 3D position and orientation relative to a field-of-view (FOV) of an optical camera that is capturing an optical image of the site. Navigational information associated with the 3D position and orientation is determined. A virtual representation of the navigational information overlaid on the FOV and displayed. The displayed virtual representation is updated when the 3D position and orientation of the tracked tool changes or when the FOV changes, in accordance with the change.

  • Patent number: 11790958
    Abstract: A method of operating a memory device is provided. A clock signal is received. Each clock cycle of the clock signal initiates a write operation or a read operation in a memory device. A power nap period is then determined. The power nap period is compared with a clock cycle period to determine that the power nap period is less than the clock cycle period of the clock signal. A header control signal is generated in response to determining that the power nap period is less than the clock cycle period. The header control signal turns off a header of a component of the memory device.
