When Law Enforcement and Military teams are entering a premises or hostile environment, they often use a distraction device to create temporary confusion and disorientation of target individuals. Conventional flash-bangs carry significant risk of collateral damage through fire, smoke inhalation, high temperature burns and fragmentation. The invention proposes a modular, reloadable, non-lethal solution offering various form factors. They significantly reduce/eliminate collateral damage. The devices utilise the same principle—single or multiple machined port(s), plus pyrotechnic ignitor. Gas pressure expanding inside each port ruptures a membrane. The release of this pressure creates a sound impulse. For GMOE (Glass method of Entry) Hand-held, Wired & RF initiated devices, gas pressure created by the ignitor functioning drives a captive hardened steel punch forward. The punch ruptures a membrane on the front face of the device breaking any glass it is in contact with.

The invention relates to a complex proximity safety and warning system. The invention provides a safety system comprising a generator that generates a magnetic field that establishes a boundary, where the generator is capable of receiving radio frequency signals. Also provided is a radio frequency device that sends radio frequency signals, the radio frequency device being capable of sensing the magnetic field and generating a radio frequency response.
