A method for covertly creating adverse health effects in a human subject includes generating at least one electromagnetic wave at a frequency within the range of about 300 MHz (megahertz) and about 300 GHz (gigahertz). The at least one electromagnetic energy wave is pulsed at a pulse frequency within a target range of human neural oscillations. The at least one pulsed electromagnetic wave is remotely transmitted to the subject's brain.

Methods and systems are provided for responding to an attacker including a shooter who opens fire at a site where people are gathered, including identifying, neutralizing, and restraining the attacker. A system may include a central control unit configured to perform a series of steps including: receiving an image including the origin of the gunfire and responsively acquiring identifying features of a shooter associated with the gunfire; subsequently tracking a current location of the shooter according to the identifying features; releasing an autonomous, unmanned aerial vehicle (UAV) to engage the shooter; guiding the flight of the UAV towards the current location of the shooter; and neutralizing the shooter by operating a shooter incapacitating mechanism of the UAV.

Haptic feedback system that simulates a detonation or explosive event. The system includes a power supply, an energy storage circuit, a switching circuit, and a conductor operatively connected to said energy storage circuit through said switching circuit whereby said conductor causes a haptic event when said energy storage circuit is electrically connected to said conductor by operation of said switching circuit. The system creates shock waves and pressure waves in a safe manner for use in a simulator.

The instant application discloses, among other things, devices and techniques for using high-intensity focused ultrasound (HIFU) for detonation of explosives. In one embodiment, a device configured to hold small, disposable, ultrasonic transducer arrays suitable for disposal, detonation, or other manipulation of explosives and hazardous materials is provided.

Systems and methods for drone mitigation, or the deterrence of aerial drones from flying in an given area, are described. The systems and methods take advantage of the fact that destabilization of a drone can be accomplished by externally changing the performance of one or more of its propeller driven systems. In doing so, the drone is incapable of maintaining stability in flight, thereby causing the remote controlled pilot to force a retreat, or risk and result in a crash of the drone. Embodiments utilizing sonic energy and liquids are described.

Disclosed herein are embodiments of a method for averting a danger. The method is performed by a control apparatus for an unmanned vehicle, and the method involves obtaining a plurality of pieces of sensor information. At least partially depending on the obtained pieces of sensor information it is determined whether a danger exists. If it is determined that a danger exists, then at least one averting measure for averting the danger is determined, and the at least one averting measure is performed or caused to be performed.

An active automated anti-boarding device for a maritime asset security system includes a housing for mounting the device on a maritime asset. The deterrence device includes visual and sound deterrence emitters within said mount to disperse a directional fan pattern of sight and visual deterrence response outward from the housing to unauthorized boarders. An active automated anti-boarding maritime asset security system includes detection devices configured to mount to maritime asset, the detection devices each including emitters and receivers for generating and detection beams that form a virtual fence to form a detection network on a portion or around an entire maritime asset. Deterrence devices responsive to the interruption of the spaced apart detection beams produce a deterrent response that is non lethal. The deterrence response can be a law enforcement level of deterrence, it can induce discomfort and/or disorientation to deter unauthorized boarders. The deterrence response can be strong enough to cause physical pain in an authorized boarder.

Disclosed are hand-held devices containing a combination of an ultra-bright LED light component and, an additional component selected from one or more of the following: an electronic-shock device, video camera and/or an ultrasound generating component powered by a battery, together with means to activate each. The device(s) may be configured to allow activation of one or all of the lights, an electronic-shock device, and ultrasound components disposed in a suitable housing. The device(s) may have a structural design similar to a hand gun but optionally colored in such a way as to not be confused with a real firearm.
