Abstract: A method includes: establishing wireless connection between an unmanned aerial vehicle (UAV) and a user interface; generating, via the user interface, a flight path for the unmanned aerial vehicle; generating, via the user interface, a flight schedule for the unmanned aerial vehicle, the flight schedule being associated with the flight path and include one or more designated times; and initiating, via the user interface, autonomous operation of the unmanned aerial vehicle for the unmanned aerial vehicle to autonomously fly the flight path at the one or more designated times

Abstract: Technology for generating and displaying a graphical user interface for operating an unmanned aerial vehicle (UAV) is disclosed herein that generates and updates a representation of a spline flight path. In various implementations, a graphical user interface detects user interactions with a remote control device directing the flight control subsystem of the UAV to record keyframes and to compute a spline based on the keyframes during flight. The graphical user interface displays a real-time perspective of the UAV with a representation of the spline and the keyframes overlaying the view. The graphical user interface continually updates the representation as the UAV flies and when the spline is updated as the keyframes are updated.

Abstract: An autonomous vehicle that is equipped with image capture devices can use information gathered from the image capture devices to plan a future three-dimensional (3D) trajectory through a physical environment. To this end, a technique is described for image-space based motion planning. In an embodiment, a planned 3D trajectory is projected into an image-space of an image captured by the autonomous vehicle. The planned 3D trajectory is then optimized according to a cost function derived from information (e.g., depth estimates) in the captured image. The cost function associates higher cost values with identified regions of the captured image that are associated with areas of the physical environment into which travel is risky or otherwise undesirable. The autonomous vehicle is thereby encouraged to avoid these areas while satisfying other motion planning objectives.

Abstract: A shelf stable, edible sphere containing alcohol and methods for preparing the same. The edible sphere comprises a liquid and/or gel inner core comprising ethyl alcohol and an outer membrane comprising alginate, wherein the outer membrane coats and encapsulates the liquid and/or gel inner core and wherein the edible sphere is shelf stable for at least one month.

Abstract: An axial-flow blood pump has a rotatable impeller assembly rotatable about an axis and itself having a radially projecting blade and permanent magnets, A stationary stator assembly has stator windings interacting with the permanent magnets and a bearing system supporting the rotatable impeller assembly for rotation about the axis relative to the stator assembly. A stent implantable into a blood vessel is connected to ends of supports for coaxially mounting the stator assembly carrying the impeller assembly in the stent.

Abstract: The invention relates to an axial flow blood pump device comprising an integrated electromagnetic drive with a stationary stator assembly and a rotatable impeller assembly, wherein the stationary stator assembly at least comprises stator windings (3) and a bearing system (4) supporting the rotatable impeller assembly, the impeller assembly comprising at least one blade (9) and permanent magnets (10) interacting with the stator windings (3), wherein the stationary stator assembly comprises supporting elements (8) for mounting, in particular coaxially mounting the device in the interior of an anchoring system (7) being implantable into a vessel.

Abstract: An internally mounted rowboat rowing fin system that includes two rotating fin assemblies mounted on the inside surface of the watercraft's opposite sidewalls. Each fin assembly includes a rotating vertical post held on the inside surface of the sidewall by a mounting tube selectively mounted or integrally formed on the sidewall. Longitudinally aligned and disposed inside each mounting tube is a hollow, elongated sleeve. Disposed inside each elongated sleeve is a rotating post that extends upward above the gunwale and into the water below the elongated sleeve. A pivoting fin arm with a flexible fin attached thereto is pivotally attached to the lower end of each rotating post. Attached to the upper end of each rotating post is a perpendicularly aligned handle bracket. A rowing handle is pivotally attached at one end to the handle hinge. During use, the two handles extend inward from the sidewall and are grasped by the rower.

Abstract: A valve, for example a tapered plug valve, having two obturators each rotatable between open and closed positions. The angle between the rotational axes is at least about 90° and may be 180°. The handles used to rotate the obturators are preferably on the same side of the valve.

Abstract: A tire splitting apparatus for splitting tire casings circumferentially into segments which includes a frame having a generally horizontal tire support table. Tire casing drive means are associated with the support table such that the drive means drivingly engages the outer crown of a tire casing and rotates the tire casing on the support table. Also included are at least two opposing guides for engaging the outer crown of a tire casing such that a tire casing situated on the support table rotates substantially over the center of the support table. A tire casing situated and rotated on the support table may be cut circumferentially with slicing means mounted on the support table generally opposite the drive means. Finally, adjustment means are provided for selectively engaging tire casings of varying diameters.

Abstract: A movable chick guard adapted for use with a conveyor feeder of the type having a conveying chain movable in a feed trough, includes a bracket, an elongated kicker member having an upturned forward end, and a depending leg member secured at the rear end of the kicker member to the bracket. The kicker member is pivotally secured to the bracket for movement between a first position at which it rides on the conveying chain to kick small chicks off the conveying chain and a second position at which it lies on a conveyor corner housing. When in the second position, the kicker member tends to keep mature chickens from sitting on the housing and the depending leg member blocks the opening to the housing.

Abstract: An anchoring system for rock bolts which support and reinforce rock structures, primarily roof structures in underground mines. The anchoring system involves the coaction of: (1) a hardenable grout such as a synthetic resin; and (2) a simple but specially designed rock bolt which has a frustum or wedge portion or element at its inner end. In this system, the wedge is secured to or forms a part of the rock bolt and the bolt is anchored by the direct mechanical action of the wedge against the hardened grout, with the wedge causing the grout to be placed under compression as the wedge slides through the grout. The anchoring is accomplished without changing the position of movable mechanical parts and without grouting along the entire length of the rock bolt.
