  • Patent number: 6477933
    Abstract: A wire-tethered dart cartridge for electrical discharge weapons wherein the sudden force needed to propel the darts toward a remote target is derived from a source of energy other than expanding gas. The propulsive force is derived from potential energy stored in at least one coiled spring having an arm which impacts the dart with sufficient force to propel the dart a desired distance toward a remote target. In a preferred embodiment disclosed herein, the spring is formed on two interconnected coils, each end of the spring wire extending from a respective coil and forming an impact arm for striking the back of a dart. The arms are maintained in a tensioned configuration by a retention bracket which is connected to a piston pyrotechnic device. When an electrical voltage is applied to the pyrotechnic device, the ignition forces the piston to move the retention bracket to suddenly release the arms.

  • Patent number: 6360645
    Abstract: An addition device which permits a user of a close proximity electrical discharge weapon to modify his or her weapon by providing a long range capability which can be added as an after-market improvement. In a preferred embodiment illustrated and described herein, the original close proximity device is a hand-held plastic device having a pair of extending contact probes for disabling a nearby perpetrator. The invention is an apparatus designed to be mechanically and electrically attached to the device and provides an unchambered wire-tethered dart cartridge which extends above the weapon and gives the user the additional capability of contacting long range targets. The apparatus permits easy and convenient replacement of spent cartridges as well as easy and convenient connection to and disconnection from the close proximity device.

  • Patent number: 6269726
    Abstract: An armored, motorized unit incorporating a gimbaled gun sighted video camera and an attached multi-shot TASER® cartridge firing system to remotely fire one cartridge at a time at a remotely selected target. A remotely located operator rotates the unit in azimuth and elevation to aim at a target within the range of the firing system. The firing system has multiple cartridges that can be rotated into a boresight position, one at a time, and armed, one at a time, for firing a pair of wire-tethered contacts such as darts at the selected target.

  • Patent number: 6053088
    Abstract: An addition device which permits a user of a close proximity electrical discharge weapon to modify his or her weapon by providing an improved short range capability as well as a long range capability which can be added as an after-market improvement. The invention is an apparatus designed to be mechanically and electrically attached to the device and provides a wire-tethered dart cartridge which extends above the weapon and gives the user the additional capability of contacting long range targets. The apparatus permits easy and convenient replacement of spent cartridges as well as easy and convenient connection to the close proximity device. The apparatus also improves short range performance by widening the separation of contact electrodes and by increasing the penetration voltage to increase effectiveness.

  • Patent number: 5955695
    Abstract: The non-lethal TASER.RTM. Area Denial Device (TADD) can be deployed to prevent enemy reconnaissance troops or small raiding parties from penetrating lines and for their capture. The inventive device comprises a non-lethal alternative to the anti-personnel landmine. The TASER.RTM. alternative uses electronic stun capability in combination with a landmine housing and deployment system. This invention comprises improvements which address the issue of deployment. Regardless of which of the two flat sides of the device is in the up position, it provides the ability to launch the proper set of wires at an upward angle to intercept the subject when the target subject is in the correct position. It also simultaneously establishes a ground wire connection and prevents the second (downward facing) unusable set of wires from loading or short circuiting. The possibility of the device landing on the radius edge is eliminated by shaping the housing to make it unstable on that plane.

  • Patent number: 5936183
    Abstract: A non-lethal alternative to the anti-personnel landmine. The TASER.RTM. alternative uses electronic stun capability in combination with a landmine housing and deployment system. The device can cover a radius of 15 feet (30 feet possible) and can be triggered by various sensors. Although the TASER.RTM. non-lethal area denial device would cause no deaths or injuries if accidentally triggered by friendly forces, it can also be permanently disabled when no longer needed, by remotely using a secure code to shut down the TASER.RTM. system. When triggered, the device launches darts in multiple directions at 10 or 20 degree intervals in a direction generally facing the enemy. The darts temporarily incapacitate any persons within an inch of the darts by causing uncontrollable spasms of the near surface motor control muscles causing temporary loss of the subject's motor control functions. The subject will fall and temporarily be completely incapacitated.

  • Patent number: 5841622
    Abstract: An electrical restraint device which, while compact and convenient for guards to install on often resistive prisoners, can accommodate a spacing of the opposed circuit contacts through a specific critical portion of the human body, so an adequately brief shock from the circuit can temporarily arrest function in the involved portions of the coordinated human muscular skeletal system and, thereby compromise the shocked individual's ambulation with the individual experiencing pain for only an extremely brief period and without causing deep burns to any significant area of his/her body. Shocking current discharged from the circuit, completes a minimal path between the prisoner's legs through a significant area of his/her legs and torso. Preferably, one contact is located at the right leg where the biceps muscle terminates into the knee and the opposing contact is located at the left leg where the biceps muscle terminates into the knee.

  • Patent number: 5012606
    Abstract: A solenoid current regulating circuit for use with shotgun gunlocks wherein the circuit provides a high activation current to flow momentarily to the coil so that the bolt of the solenoid controlled gunlock can be drawn back. However, upon continued depression of the activation switch, the circuit of the present invention automatically reduces the holding current to the solenoid coil so that the coil is protected from current damage. The circuit utilizes a resistor/capacitor network having an RC constant of less than one second for providing delayed biasing of a transistor which, when in its conductive state, reduces the gain of a current source transistor thereby reducing the current for the solenoid coil and thereby reducing the current flow through the coil of the solenoid to a level sufficient to hold the solenoid active and retain the bolt in its unlocked position.
