Abstract: Falling drone warning apparatuses and methods are disclosed. The apparatus may be attached to a drone and may measure acceleration during the drone's operation in order to ascertain whether the drone is free falling. If the apparatus detects that the drone is free falling, the apparatus may activate an audible alarm to warn people on the ground of the potential danger and to afford them the opportunity to take action to avoid the drone's impact or minimize its effect.

Abstract: Systems and methods for mapping sensor feedback onto virtual representations of detection surfaces are disclosed herein. A system configured in accordance with an embodiment of the present technology can, for example, record and process feedback from a sensing device (e.g., a metal detector), record and process user inputs from a user input device (e.g. user-determined locations of disturbances in the soil surface), determine the 3D position, orientation, and motion of the sensing device with respect to a detection surface (e.g., a region of land being surveyed for landmines) and visually integrate captured and computed information to support decision-making (e.g. overlay a feedback intensity map on an image of the ground surface). In various embodiments, the system can also determine the 3D position, orientation, and motion of the sensing device with respect to the earth's absolute coordinate frame, and/or record and process information about the detection surface.

Abstract: Compositions and methods are provided for reversing and/or inhibiting inflammation, e.g., by inhibiting prostaglandin and/or COX-2 production, using one or more indolequinazoline alkaloids, preferably in combination with butylated hydroxytoluene. The preferred indolequinazoline alkaloids are rutaecarpine, evodiamine, and dehydroevodiamine, which are naturally found in unpurified form in the traditional Chinese medicine Wu Chu Yu made from the fruit of the herb, Evodia rutaecarpa.
