Described are systems and methods for active weathervaning of a hybrid flight aerial vehicle, such as an unmanned aerial vehicle (UAV). Active weathervaning of the hybrid flight aerial vehicle during can be provided during vertical takeoff and landing (VTOL)/hover flight without the assistance of any low-speed wind sensors and during transitions between VTOL/hover flight and fixed-wing, wing-borne, horizontal flight. Additionally, active weathervaning can be provided during propulsion mechanism failure conditions where the aerial vehicle may be experiencing failure conditions associated with one or more propulsion mechanisms.

Weathervaning for hybrid flight aircraft

Various embodiments disclose systems and methods for tracking regions (e.g., tumor locations) within living organisms. Some embodiments provide real-time, highly accurate, low latency measurements of tumor location even as the tumor moves with internal body motions. Such measurements may be suitable for closed-loop radiation delivery applications where radiation therapy may be continuously guided to the tumor site even as the tumor moves. Tumor motion may be associated with periodic motion (e.g., respiratory, cardiac) or aperiodic motion (e.g., gross patient motion, internal bowel motion). Various embodiments facilitate accurate radiation delivery to tumor sites exhibiting significant motion, e.g., lung, breast, and liver tumors.

Systems and methods for real-time tumor tracking

Various embodiments disclose systems and methods for tracking regions (e.g., tumor locations) within living organisms. Some embodiments provide real-time, highly accurate, low latency measurements of tumor location even as the tumor moves with internal body motions. Such measurements may be suitable for closed-loop radiation delivery applications where radiation therapy may be continuously guided to the tumor site even as the tumor moves. Particularly, the system may dynamically identify planned to actual fiducial correspondences by iterating through the possible assignment permutations. A successful permutation may be recorded and used to orient the patient during follow up treatment sessions.

Systems and methods for fiducial to plan association

A method of detecting a possible collision in a medical procedure that involves a medical system, includes: obtaining an image of a patient that is supported on a patient support; determining a first model using a processing unit based at least in part on the image, at least a part of the first model representing a surface of the patient; determining a second model using the processing unit, the second model representing a first component of the medical system; virtually moving the first model, the second model, or both, using a collision prediction mechanism to simulate a movement of the first component of the medical system to determine whether there is a possible collision between the first component and the patient; and generating an output to indicate the possible collision or an absence of the possible collision.

System and method for collision avoidance in medical systems

A system and method of non-linear grid fitting and coordinate system mapping may employ data processing techniques for fitting a set of measured fiducial data to an ideal set of fiducials; the fiducials may be arranged in a known (e.g., Cartesian grid) pattern on a substrate imaged by an imaging apparatus. Exemplary embodiments may model the non-linear transformation to and from imaged coordinates (i.e., coordinates derived from acquired image data) and artifact coordinates on the fiducial plate (i.e., actual coordinates of the fiducial relative to a reference point on the fiducial plate).

System and method of non-linear grid fitting and coordinate system mapping

A system and method allow accurate calculation of probe float through optical free-hanging and electrical planarity measurement techniques. In accordance with an examplary embodiment, probe float may be determined by acquiring a free-hanging planarity measurement, obtaining a first electrical contact planarity measurement, and calculating probe float using results of the acquiring and the obtaining operations.

A system and method of mitigating the effects of component deflections in a probe card analyzer system may implement three-dimensional comparative optical metrology techniques to model deflection characteristics. An exemplary system and method combine non-bussed electrical planarity measurements with fast optical planarity measurements to produce 'effectively loaded' planarity measurements.

A stereoscopic three-dimensional optical metrology system and method accurately measure the location of physical features on a test article in a manner that is fast and robust to surface contour discontinuities. Disclosed embodiments may image a test article from two or more perspectives through a substantially transparent fiducial plate bearing a fiducial marking; camera viewing angles and apparent relative distances between a feature on a test article and one or more fiducials may enable accurate calculation of feature position.

Stereoscopic three-dimensional metrology system and method

A system and method of point matching measured positions to template, or reference, positions for various applications may generally comprise creating force field vectors and moments operative to perturb measured point locations into alignment with template point locations. Progressive reduction of the force radius may produce results that match very well for points that are highly correlated with the template pattern.
