  • Patent number: 8231474
    Abstract: A baton includes an elongate housing with a first compartment and a second compartment. A power source is located in the first compartment. An interchangeable operative component is located in the second compartment and may be removable/replaceable. The interchangeable operative component may be a training module, a light source, a laser generator, a sound generator, an incapacitation waveform generator, and combinations thereof.
    Type: Grant

  • Publication number: 20100214714
    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: 20100134090
    Abstract: A method of testing an electric discharge stun device includes the steps of identifying a stun device to be tested and absorbing a discharge from the stun device into a tester. The discharge is characterized by a discharge characteristic that is then compared automatically to information such as (a) a previous corresponding characteristic associated with a previous discharge of the stun device or (b) a corresponding characteristic associated with a prior discharge of at least one other stun device. The characteristic can be a waveform, a peak voltage, duration, current, joule, and temperature.

  • Patent number: 6791816
    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.
