A fact checking system utilizes social networking information and analyzes and determines the factual accuracy of information and/or characterizes the information by comparing the information with source information. The social networking fact checking system automatically monitors information, processes the information, fact checks the information and/or provides a status of the information, including automatically modifying a web page to include the fact check results. The fact checking system is able to be implemented utilizing a drone device.

An advanced acoustic awareness platform configured to classify environmental sounds. The advanced acoustic awareness platform comprises an audio signal acquisition sensor array and one or more processors programmed to augment the audio signal, extract features for the audio signal, visualize, and classify the signal using one or more labels. In at least one embodiment, the signal is classified based on transfer learning associated with a pretrained machine learning model.

A bladed disc for masking a moving disc of a jet engine, including blades, each blade including a pressure-side wall and a suction-side wall that meet at a leading-edge and at a trailing edge, and wherein each blade has a pressure-side wall and a suction-side wall each including a concave zone and a convex zone that are at a distance from the leading-edge and from the trailing edge and are spaced apart from one another, these concave zones and these convex zones each extending over the majority of the height of the blade, the concave zone of the pressure-side wall is opposite the convex zone of the suction-side wall, the concave zone of the suction-side wall is opposite the convex zone of the pressure-side wall.

The invention comprises of a UAV designed to limit visually contrast and audibility in flight for covert surveillance operations, a method of configuring the UAVs structure to further reduce its visual signature to take account for the atmospheric and terrestrial environment it will operate in and a method of conducting a covert surveillance operation to actively minimise the UAVs visual & auditory signature from the viewpoint of an individual under surveillance. Both passive and active illumination are used to reduce the visual signature of the UAV. The UAV is actively camouflaged using lighting techniques that utilises the limitations of the human visual system and the optical effects of light interacting with the terrain, atmosphere and aircraft. The visual camouflage is directional. The audible signature of the UAV is reduced through the design of the propulsion system and the mode in which the UAV is operated.

A drone autonomously operates to track an object, track an object while being stealthy and/or observe the details of an object while maintaining communication at a rate equal to or greater than a threshold. A drone may operate to maintain the image of an object at or above a predetermined resolution in an image captured by a camera mounted on the drone and to maintain a wireless communication rate equal to or greater than a threshold rate. A drone may operate so that the sound intensity level caused by the operation of the drone is less than or equal to a sound intensity level threshold as perceived by an object (e.g., person, target, suspect) being tracked.

A highly-conformal, pliable thin electromagnetic (EM) skin for altering at least one electromagnetic property of a surface includes a pliable thin film, and sub-wavelength elements incorporated into and/or on the pliable thin film which are smaller in scale than the wavelengths of electromagnetic radiation they are intended to influence. The electromagnetic skin readily conforms to contours of a surface to which it attaches or otherwise adheres to. Such electromagnetic skin can be used to cover various surface and platforms on equipment, walls, vehicles, and aircraft to change the electromagnetic properties of such surfaces to achieve certain functions that are not achievable with simple ground plane surfaces. The EM skin may be judiciously configured to alter at least one electromagnetic property of the surface by blocking, absorbing, enhancing, and/or bending waves of electromagnetic radiation.

Disclosed is a low-altitude unmanned aerial vehicle surveillance system. According to an embodiment, monitoring is performed using a balloon main body filled with gas and staying in the air; radar; camera units being provided outside the balloon main body, and including a camera taking an image of a subject; radio frequency detectors; and sound detectors and correspondingly, interceptor means is included. As interceptor means, a jammer, a jamming gun, and a spoofing device corresponding to jamming are disclosed.
