An apparatus for monitoring one or more surgical parameters of the eye over multiple sessions which are temporally spaced apart and between which the eye of the patient can have moved, said apparatus comprising: a camera for taking one or more images of the eye; a module for determining during a first session said at least one surgical parameter of the eye and its coordinates based on the image taken by said camera in a first coordinate system; a module for determining during a second session temporally spaced apart from said first session said at least one surgical parameter of the eye and its coordinates based on the image taken by said camera in a second coordinate system; a module for determining the eye motion in six degrees of freedom between said first and said second session and for determining a coordinate transformation based thereon; a module for transforming based on said determined eye motion said at least one surgical parameter of the eye and its coordinates from said first coordinate system into said second coordinate system; a module for quantifying and/or visualizing the change of said at least one surgical parameter of the eye and its coordinates between said first and said second session based on said surgical eye parameter and its coordinates measured during said second session and said transformed surgical eye parameter and its coordinates measured during said first session, wherein said surgical eye parameters are one or more of the following: implant-related parameters of the eye which are based on an implant which has been surgically placed in the eye of a patient; or the location and/or contour of corneal or limbal or scleral incisions.. .

Method to estimate real-time rotation and translation of a target with a single x-ray imager
A method of real-time estimation of target rotation and translation for 6 degrees of freedom using a single planar 2-dimensional imager and an algorithm, such as the iterative closest point (icp) algorithm, that includes creating pairing, using a nearest neighbor algorithm, between a set of target points of at least three fiducial markers and a set of source points of the markers using k nearest neighbors, iteratively executing estimation of a rotation parameter r and a translation parameter t of the markers using a cost function such as root mean square error, terminating the estimation of r and t if the change in a mean distance between the set of target points of the markers and the set of source points of the markers is below a threshold or at a maximum iteration number, transforming the set of target points of the markers using estimated parameters, and re-associating a new set of the target points of the markers.. .

Apparatus for monitoring one or more parameters of the eye
An apparatus for monitoring one or more parameters of the eye of a patient over multiple sessions which are temporally spaced apart and between which the eye of the patient can have moved, said apparatus comprising: a camera for taking one or more images of the eye; an illumination unit for illuminating the eye by a ring-shaped light pattern to generate corneal reflections, said illumination unit being preferably located such that the center of the ring is coaxial with the optical axis of the camera; a module for determining during a first session the location of the corneal reflections in the image of the eye; a module for determining during said first session based on said determined location of the corneal reflections, at least one further parameter of the eye and its coordinates in a first coordinate system based on a geometrical model representing the eye as a spherical eyeball having a spherically shaped cornea mounted thereon; a module for determining during a second session temporally spaced apart from said first session said location of said corneal reflections of the eye and based thereon said further eye parameter and its coordinates in a second coordinate system; a module for determining the eye motion in six degrees of freedom between said first and said second session and for determining a coordinate transformation based thereon; a module for transforming based on said determined eye motion said further eye parameter and its coordinates from said first coordinate system into said second coordinate system; a module for quantifying and/or visualizing the change of said further eye parameter between said first and said second session based on said further parameter and its coordinates measured during said second session and said transformed parameter and its coordinates measured during said first session.. .

Rotocraft
An aerial vehicle includes independently controlled horizontal thrusters and vertical lifters to provide design and operational simplicity while allowing precision flying with six degrees of freedom and use of mounted devices such as tools, sensors, and instruments. Each horizontal thruster and vertical lifter can be mounted as constant-pitch, fixed-axis rotors while still allowing for precise control of yaw, pitch, roll, horizontal movement, and vertical elevation.
