  • Method of calibration of a stereoscopic camera system for use with a radio therapy treatment apparatus
    Patent number: 9962561
    Abstract: Some embodiments are directed to a calibration method including a calibration phantom positioned on an adjustable table on the surface of a mechanical couch, with the phantom's center at an estimated location for the iso-center of a radio therapy treatment apparatus. The calibration phantom is then irradiated using the apparatus, and the relative location of the center of the calibration phantom and the iso-center of the apparatus is determined by analyzing images of the irradiation. The calibration phantom is then repositioned by the mechanical couch applying an offset corresponding to the determined relative location of the center of the calibration phantom and the iso-center of the apparatus to the calibration phantom. Images of the relocated calibration phantom are obtained, and the images are processed to set the co-ordinate system of a 3D camera system relative to the iso-center of the apparatus.

  • Mechanical Fiber Switch
    Publication number: 20180120511
    Abstract: A switch for selectively coupling light from two input fibers to a selected two of plurality of output optical fibers. The switch was designed to handle standard Fiber optical connectors which have been polished and meet the specifications for the optical performance. The duplex mechanical switch creates a method to physically switch two fibers (Duplex) to another two fibers (Duplex). The performance regarding insertion losses, back reflection, crosstalk, immunity against backscattering of light and insensitivity to the wavelength of the light is consistent with this mechanical switch.

  • Double-Action, Adjustable, After-Market Sash Stop
    Publication number: 20180119463
    Abstract: An adjustable stop limits sliding sash window/door travel between a closed position and a safe position, where the safe position is a position less than a full-open position. The stop can be installed upon window/door master frames during initial manufacturing, or as an after-market option while the sash windows/doors are in service in a building. The safety stop may be comprised of a housing and a tumbler being pivotally mounted within a cavity in the housing, with a spring to bias the tumbler out of an opening in the housing. Mounting is by a flange extending from the housing, with spacers of varying thickness that are capable of removably attaching thereon to accommodate sash to master frame height differences. A safety member may be added to either the tumbler or housing to create a double action stop, requiring disengagement of the safety member, prior to toggling of the stop.

  • Dense structure from motion
    Patent number: 9959595
    Abstract: Determining three-dimensional structure in a road environment using a system mountable in a host vehicle including a camera connectable to a processor. Multiple image frames are captured in the field of view of the camera. In the image frames, a line is selected below which the road is imaged. The line separates between upper images essentially excluding images of the road and lower images essentially including images of the road. One or more of the lower images is warped, according to a road homography to produce at least one warped lower image. The three-dimensional structure may be provided from motion of a matching feature within the upper images or from motion of a matching feature within at least one of the lower images and at least one warped lower image.
