A drone for deterring intruders within a monitored area includes a multirotor aerial vehicle with an electric drive apparatus and a power supply configured to provide electrical energy. A controller is configured to control the multirotor aerial vehicle. A first sensor is in electrical communication with the controller, the sensor configured to provide navigation information to the controller. A wireless communication circuit is in electrical communication with the controller, and in wireless communication with an external wireless transceiver. A deterrence effector bay is in electrical communication with the controller. The deterrence effector bay includes a non-lethal deterrence effector and an actuator. Activation of the actuator causes the delivery of the non-lethal deterrence effector to a target. The drone may be used in conjunction with an alarm system as a deterrent against intrusion.

A non-lethal electronic defense device comprising one or more effects such as light, sonic, ultrasonic, infrasonic, chemical, electrical, or mechanical devices capable of causing intense sensations of disorientation, distress, incapacitation, and/or pain for the purpose of protecting a public or private space from an intruder or attacker exhibiting an intent to cause harm to physical inhabitants or destruction of property therein.

The invention herein disclosed is a non-lethal crowd-control system that uses ultrasonic sound waves to induce disarming sensations of tickling/tingling upon persons in a hostile/violent crowd who are located within a zone of desired crowd control. The sensations can cause persons to cease current behavior and attempt to eliminate the sensations. Moving backwards out of the areal zone of control will reduce or eliminate the sensations. As a result a control zone area is established without use of batons, sprays or rubber-bullet loaded weaponry.

There is disclosed a flash device for selective activation where upon activation the device may emit at least 100,000 lumens, the flash device comprising, an operator interface, a power unit comprising an energy store, at least one light emission unit connected to the power unit and comprising an array of light emitting elements, a power converter unit for driving the array, a control unit operably connected to the at least one light emission unit, the control unit comprising a processor and being operably connected to the operator interface.

This disclosure generally relates to a non-lethal disruption device that is meant to disorient and/or confuse an individual using lights and/or sound. The lights and/or sound are emitted from the non-lethal disruption device at a particular pattern and/or frequency in response to a triggering event.

A non-lethal, non-impact smart projectile fired from a suitable launcher and equipped with a digital camera, CPU microprocessor and computer vision programming that can recognize a designated target and track a moving target, while moving at high speed. An image dataset of the target stored in memory of the CPU that enables the projectile to recognize a human or small UAV drone in real time within fractions of a second. A steering and braking system comprising several fins/air brakes, controlled by the CPU and MEMS micro-actuators, that enable the projectile to track a moving target or slow the projectile down. A projectile equipped with actuators that dispenses a non-lethal, non-impact payload or payloads as the projectile approaches the target.

In an embodiment, a self-defense system is disclosed. The self-defense system may include or comprise a material sized to conform to an appendage, and a defense unit coupled with the material and positioned to initiate a defense event in response to an input.

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.

An apparatus has a lens. A frame has a gasket for receiving the lens and a shock-resistant housing is secured about the frame. A visual output element is disposed proximate the lens and an audio output element is disposed within the housing. A control component with a power source is provided for controlling at least one of the visual output element and the audio output element.

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.
