Abstract: An action camera system for an unmanned aerial vehicle (UAV) selects a target based on a reference image captured by an onboard camera. Image processing determines a desired orientation of the target to the UAV, by which the UAV can track the target and provide streaming video images from the desired orientation. Image processing establishes a visual lock on the target and controls the UAV to maintain the desired orientation while capturing streaming images. Additional position data provided by sensors aboard a smartphone carried by the target enhances the tracking ability of the action camera system and enables predictive analysis of the target's future position. The action camera system may additionally provide preselected modes of operation that control UAV movement and image capture depending on the user's desired objectives.

Abstract: An unmanned aerial vehicle (UAV) may select a subject to track or follow and capture images including the subject. A visual recognition system of the UAV may generate a profile of reference images portraying the subject breaking the reference images down into pixel sets corresponding to the subject and his/her components and distinguishing characteristics (body parts, clothing, facial features, accessories). The visual recognition system may break the incoming stream of incoming images into pixel sets, analyzing the pixel sets to distinguish the subject from his/her surroundings (i.e., in a crowd) and determine movement of the subject and the current orientation of the UAV to the subject. The UAV may then change its heading, velocity, or position based on any difference between the current orientation and the desired or predetermined orientation between the UAV and the subject.

Abstract: A system and method for power management aboard an unmanned aerial vehicle (UAV) configured to follow a subject based on images captured by an onboard camera includes a power monitor that determines if available power from the UAV's onboard batteries has dropped below predetermined thresholds. If a low power level is detected, the power management system may divert power from non-essential systems to the attitude control system to keeping the UAV aloft. If a critical power level is detected, the power management system may shut down other UAV subsystems so that the attitude control system can safely land the UAV. The power management system may send an alert to a smartphone or other device carried by the subject. Position sensors of the subject's device may be used to interpolate the position of the UAV based on the subject's own position for recovery of the UAV.

Abstract: In a preferred embodiment, a membrane for use as an underlayment includes a basemat, which includes at least three plies, a ply of a meltblown polymer sandwiched between two plies of spunbond polymer; and a flexible coating applied to the basemat, the coating having a cementitious hydraulic component, a polymer comprising a water-soluble, film-forming polymer; and water. The finished membrane is flexible. Another embodiment for an underlayment for use underneath ceramic tiles includes a basemat and a coating of a set hydraulic component less than ?? inches thick. A method of making the flexible membrane includes assembling components including a hydraulic component, a water-soluble, film-forming polymer and water, then mixing them to form a coating. A basemat is provided onto which the coating is applied over a flexible surface or no surface. After coating at least one face of the basemat, the coating is dried to form the membrane.

Abstract: Some embodiments provide methods and apparatuses for performing a near-instantaneous restore of a database. During operation, the system intercepts a database management system restore request to restore a database from a backup file to a data file, wherein the backup file comprises a first number (e.g., N1) of data pages. Next, in response to intercepting the database management system restore request, the system sends information to the database management system indicating that the backup file comprises a second number (e.g., N2) of data pages, wherein the second number of data pages is less than the first number of data pages (e.g., N2<N1). Once the database management system has copied the fewer number of data pages from the backup file to the data file, the database management system may indicate that the restore is complete, and continue processing database requests as if the database management system was back online.
