Modular personal defense device

Abstract

The modular personal defense device is a hard, rigid, elongate baton that is capable of imparting impact force to an assailant or threat. The exterior may include a series of strengthening ribs, which may also impart further damage to an assailant. The interior is an essentially hollow cylinder configured to accept one of a series of modules. The modules are essentially externally physically identical, but include different electronic circuitry and mechanisms to provide different functions. A silicone controlled rectifier (SCR) electronic stun circuit is provided by one module, for imparting a stunning electrical shock and dissuading an assailant(s) due to the electrical arc produced. Another module produces an extremely bright light either continuously or in rapid pulses, to blind and disorient an assailant. Yet another module produces a piercing sound, while still other modules may be fitted axially or radially to the device to transmit an irritant spray.
