Abstract: A computer accesses a first symbolic expression for an output matrix as a function of an input matrix at a computing device comprising processing circuitry and memory. The computer computes a first Jacobian of the input matrix with respect to an input tangent space. The computer computes a second Jacobian of the output matrix with respect to the input matrix. The computer computes a third Jacobian of an output tangent space with respect to the input matrix. The computer applies symbolic matrix multiplication to the first Jacobian, the second Jacobian, and the third Jacobian to obtain a second symbolic expression for the output tangent space with respect to the input tangent space. The computer provides a representation of the second symbolic expression, the second symbolic expression representing a computed tangent-space Jacobian.

Abstract: In some examples, an unmanned aerial vehicle (UAV) may determine a plurality of contour paths spaced apart from each other along at least one axis associated with a scan target. For instance, each contour path may be spaced away from a surface of the scan target based on a selected distance. The UAV may determine a plurality of image capture locations for each contour path. The image capture locations may indicate locations at which an image of a surface of the scan target is to be captured. The UAV may navigate along the plurality of contour paths based on a determined speed while capturing images of the surface of the scan target based on the image capture locations.

Abstract: Techniques for selecting TV user interface (UI) transition characteristics are described. In accordance with various embodiments, a transition characteristics selection method is performed at a device (e.g., a cloud UI engine on a server) with one or more processors and a non-transitory memory. The UI engine receives a request for transitioning from a first screen to a second screen on a client device while in a real-time content presentation mode. In response to receiving the request and while in the real-time content presentation mode, the UI engine obtains one or more presentation conditions of the client device and selects one or more transition characteristics for transitioning from the first screen to the second screen based on costs associated with the one or more transition characteristics and the one or more presentation conditions.

Abstract: A wave generating installation (100) is configured to generate a wave in water and includes a carousel (102) configured to rotate about an upright axis of rotation. A wave former (120) is fixed relative to the carousel and therefore configured to rotate with the carousel, wherein the wave former is configured to form an incoming stream of water (112) into a standing wave. A water outlet (110) is spaced away from the wave former, the water outlet being configured to direct a stream of water over part of the carousel towards the wave former. A water pump (140) is connected via a water conduit to the water outlet, thereby to produce the stream of water. The installation is configured to direct the stream of water over the rotating carousel towards the wave former, thereby to generate the wave which is a standing wave relative to the carousel but which rotates with the carousel.

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: In some implementations, a device includes one or more processors and a non-transitory memory. In some implementations, a method includes obtaining a request for a sequence of video frames that corresponds to a user interface operation being performed at a client device. In some implementations, the sequence of video frames is to be presented at the client device at a first frame rate. In some implementations, the method includes determining an availability of computing resources associated with providing the sequence of video frames to the client device. In some implementations, the method includes generating, based on the availability of computing resources, the sequence of video frames at a second frame rate that is greater than the first frame rate. In some implementations, the method includes triggering the client device to present the sequence of video frames at the first frame rate.

Abstract: A medical device system includes an elongate sheath defining a lumen extending within the elongate sheath. A coupler mechanism is slidingly disposed within the lumen, the coupler mechanism including a proximal coupler and a distal coupler. An elongate member is secured to and extends proximally from the proximal coupler. An implantable medical device (IMD) is secured to and extends distally from the distal coupler. The distal coupler remains secured to the proximal coupler while the coupler mechanism remains within the lumen, and the distal coupler releases from the proximal coupler, thereby releasing the IMD, when the coupler mechanism is exterior to the lumen.
