  • Publication number: 20080020850
    Abstract: A hollow, perforated, high-strength composite personal defense baton for personal protection has ultra-low mass for reduced likelihood and/or severity of blunt trauma injury. The baton may be held and wielded at any point along the body or shaft of the baton. Due to the low mass and perforations, one or two of the batons can be wielded with high speed and maneuverability. The high-strength, low-weight composite material offers high flexural strength, reducing blunt trauma injury compared to rigid metal, resin, and wood batons. The composite material is highly resistant to cutting, fracture, and shattering, even under extreme environmental conditions including high levels of UV exposure. The composite material is non-conductive offering collateral use with stun devices.

  • Publication number: 20070238532
    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.

  • Publication number: 20070167241
    Abstract: Incapacitation of a mammalian subject results from the application of a pulsed, low-power electric waveform. The waveform is applied to the subject at a frequency and over a time period sufficient to induce involuntary muscular contraction. Additionally, the contraction causes limited lactic acid production and is non- or minimally-injurious to the subject's tissues. A device utilizing such a waveform is designed to control or otherwise subdue an individual.

  • Publication number: 20050073798
    Abstract: Multiple embodiments of a personal defense device each include an electrical stun circuit and electrodes with a structure adapted for use as an impact weapon as well, and further include a radially disposed flashlight or signal light therewith. The electrical circuitry for the stun apparatus may be formed of flexible circuit material with dual circuit paths between each component, for reliability and resistance to damage due to impact forces incurred when the device is used as an impact weapon. A second, normally closed interrupter switch may be provided for the stun circuit, with the user of the present device being required to hold the interrupter switch in order to keep the stun circuitry from operating when the master switch is turned on. The end opposite the handle may include a series of impact ribs with cutting blades removably installable thereon, to produce non-lethal cuts in an assailant during an attack.
