An interchangeable self-defense device has two self-defense devices and two modular housings, the two self-defense devices are respectively mounted in the two modular housings, and each one of the two modular housings has a mounting structure formed on a side surface of the housing. The two mounting structures of the two modular housings can detachably interlock with each other. With the interchangeable self-defense device, the user may conveniently hold the two self-defense devices together as one piece, and also can quickly switch functions from one self-defense device to another: therefore the user may optimize the defensive strategy to cope with different situations.

A dazzling system has at least one strobe illuminator and multiple imaging optics, which may be of various types. All strobe illuminators are synchronized to each other and the imaging optics are synchronized to all strobe illuminators. The imaging optics may be in-phase or out-of-phase. Various embodiments are possible depending on the application, but in all applications the strobe illuminator(s) disrupt the vision of unauthorized persons while allowing users of the system to view a scenario.

A method of controlling at least one light source to discourage unwanted behavior at a spectator event comprising a plurality of spectator areas, the method comprising: detecting, based on sensor input received from a sensor at the spectator event, at least one spectator exhibiting unwanted behavior within a first one of the spectator areas; determining a location of the first spectator area; identifying a second one of the spectator areas as being a target of the unwanted behavior and determining a location of the second spectator area; and controlling at least one light source based on the determined locations to increase an amount of glare along at least one line of sight between the first and second spectator areas and thereby discourage the spectator from looking towards the second spectator area to discourage the unwanted behavior.

Described herein is a wearable personal safety device. The device may include one or more finger holders for receiving a user's fingers and may be held inside a person's hand. The device may include a dazzling light source and a camera and may be configured to shine a dazzling light towards a would-be attacker and to take an image with the camera.

An unmanned vehicle capable of operating in harsh environments is disclosed. The unmanned vehicle includes an aerial platform, a piloting system supported by the aerial platform, a medium source supported by the aerial platform, and a control system having a processor running computer executable code that actuates the medium source to emit a medium away from the aerial vehicle with an intensity sufficient to disorient a subject when the medium interacts with an exteroceptive sense of a subject.

A self-defense apparatus includes a sleeve portion and an adapter connected to the sleeve portion. The sleeve portion includes a proximal end surface, an outer side surface, and a distal end surface. The sleeve portion defines an implement-receiving cavity that extends axially into the proximal end surface. The sleeve portion defines an adapter-receiving passage that extends axially into the distal end surface. A proximal portion of the outer side surface defines a handle portion that includes one or more finger grooves. A distal portion of the outer side surface defines an adapter-interfacing body. A first portion of the adapter body is disposed within the adapter-receiving passage. A second portion of the adapter body extends beyond the distal end surface. A distal portion of the second portion of the adapter body defines a conical body.

In accordance with one embodiment of the present invention, a method of multi-use multi-vision modular covers comprising of aggregating multiple devices into physical meshes and virtual networks where devices exchange multi-source data transactions and transmissions between meshed devices to project on their respective screens the exchanged images, videos, and/or visual adjustments to produce multiple video See Through streams between meshed devices in static states and/or in motion. In a preferred embodiment, the invention is combination of devices, cameras, and/or screens that produce See-Through video streams with enhancements to hide, protect, and sustain modular permutations of invisible armors, invisible cloaks, invisible vehicles, invisible crafts, invisible land drones, invisible flying drones, invisible camo nettings, and other invisible configurations managed by manager-of-manager portal platforms that can provision, manage, and monitor all these configurations and deployments during a battle while producing synergies of invisible combined arms tactics to defeat the enemies of God.

Systems, methods, and articles are disclosed for the behavioral treatment of an individual. One embodiment comprising a wearable housing assembly further comprising a microcontroller, charging jack port, status monitor, selection element, sensor array, and deterring member attached to the user via a connection strap, adjustment belt, frame, prong, and adjustment hole. The user selects the input/output properties of the microcontroller, status monitor, sensor array, and deterring member using the selection element. Upon performing an undesirable emotional outburst, the user is automatically administered a deterrence element, causing the cognizance of, or the inability to engage in, the undesirable behavior. Other embodiments are described and shown.

A multifunction multitask apparatus for use in building inspections is disclosed. The apparatus comprises a portable case comprising a grippable handle, a mini-desk, lighting elements and a plurality of sensors for building structure inspection. The apparatus includes a power source in electric communication with a sensor. The apparatus may include a variety of sensors including a voltage tester, a circuit polarity sensor, and ambient air testing sensor, and ambient temperature sensor, and ambient humidity sensor, a moisture meter, a radon sensor, a carbon monoxide sensor, and an airborne toxin sensor. Other embodiments of the invention may include safety features including a first-aid cat, a chemical spray deterrent device, and a tactical prong. Other embodiments may include lights including a laser pointer, an LED light, an a focused light beam.

A flash housing for photographic purposes is disclosed. The flash housing comprises a flash forming element arranged to generate a flash light and a lens element arranged to let at least part of the generated flash light out of the flash housing so as to obtain the flash. The obtainable flash light has a beam lobe with a controllable beam angle. A simulation light generator element is arranged for simulation of the obtainable flash light beam lobe having the controllable beam angle.
