  • Patent number: 8104216
    Abstract: The present invention relates to a system and method for controlling the aimed shooting of a sniper and the observation of a spotter. At the same time that a sniper directly checks the shape of the target using a sighting telescope, a spotter observes the surroundings of the target using an observatory telescope. The sniper deflects images of the target using a prism, focuses the images, and converts the focused images into digital moving image signals. The spotter deflects images of the target using a prism, focuses the images, and converts the focused images into digital moving image signals. Two types of images can be selectively transmitted, or can be combined with each other using a multiplexer and transmitted to a shooting controller in a multi-screen division form. A commanding office can identify a precise target and make a decision pertaining to shooting.

  • Patent number: 8033207
    Abstract: An electrically actuated weapon system is provided, which may be mounted in a robotic vehicle or device, and controlled remotely by a user. In particular, the electrically actuated weapon system is composed of an electrically actuated weapon, a weapon control means connected thereto, and a controller means remotely located therefrom. The controller means is in wireless communication with the weapon control means, which is operable to control three linear actuators which cycle the weapon. These linear actuator means are controlled electronically, based on communications received from the controller means. Accordingly, if the weapon is stolen, lost, or captured by an enemy combatant during combat, the weapon will cease to be functional. Further, the weapon can be reliably operated from remote locations, as the cycling of the weapon is not dependent upon recoil forces.

    Abstract: An authorization control system controlling who may use a device, includes a device for storing personal code data, a signal provider for outputting signals representing the personal code data, a signal delivery interface for receiving signals representing the personal code data, and adapted for wear by a user in proximity to a body of the user, a signal receive interface means, connected to the device, for receiving the signal from the signal delivery interface, a signal processing device, connected to the signal receive delivery interface, for determining a user's authorization for using the device by evaluating the signals and outputting a signal indicative of an evaluation result, a control device connected to the signal processing device, and an actuator for the device coupled to the control device, for allowing the user to use the device based on an output of the control device. Thus, the system allows a person to use the device only after the person has completed a successful authorization check.

  • Patent number: 6668700
    Abstract: A trigger actuator having a substantially unitary structure with a measuring device mounted thereon to detect the application of force to the trigger. In response, the measuring device generates a trigger signal. A compensating system detects additional or undesirable effects applied to the actuator and generates a compensating signal to modify and compensate for such effects on the actuator.

  • Patent number: 6557449
    Abstract: This invention provides a handgun assembly such as a rifle (9) which has a barrel assembly (24) including a cluster of barrels each supporting a longitudinal arrangement of aerodynamically shaped, directional projectiles (15) and interposed propellant charges (16) whereby the barrel assembly has longitudinal arrays or layers or projectiles and interposed propellant charges. Ignition means is provided for selectively igniting the propellant charges (16) including for simultaneously igniting the propellant charges in the leading layer of projectiles to provide a shotgun-like blast.

  • Patent number: 6543330
    Abstract: A gun having a wedge-type breech block and a barrel seated in a cradle for firing electrically-ignitable cartridges containing electronic components, and an ignition contact (4) for connection to an external current source, and a signal contact (5) for connecting the electronic components to an external electronic control device are disposed on the cartridge base (3). To ensure reliable ignition of the cartridge, and transmission of data from the cartridge, an axially displaceable ignition and signal-transmission unit (8) is provided in the breech block, and includes a housing (11) having two parallel, axial guides (12, 13), and two spring-loaded, needle-shaped contact devices (16, 17) arranged to be displaced inside the respective guides such that, in the extended position of the unit (8), the first contact device (16) is pressed against the cartridge ignition contact (4) and the second contact device (17) is pressed against the cartridge signal contact (5).

  • Patent number: 6543174
    Abstract: A barrel assembly (70) comprising a plurality of projectiles (75) axially disposed within a barrel (71) and associated with discrete selectively ignitable propellant charges (74) for propelling the projectiles from the barrel. The essence of the invention is the provision of a pressure relief valve, for example comprised by a port (73) and plug (76), associated with a chamber in which a propellant charge (74) is ignited. The pressure relief valve (73, 76) is designed to prevent catastrophic failure of the barrel (71) by exhausting via a chamber (72) in the event that the barrel is blocked by a projectile and detonation of one or more propellant charges (74) occurs.

  • Patent number: 6526686
    Abstract: An electric charging system for a firearm includes a port in operable communication with a chamber adapted to receive an amount of expanding gas created by an ignited charge, and a cavity in operable communication with the port and adapted to receive an amount of the expanding gas therefrom. The charging system also includes a charging assembly in operable communication with the cavity, wherein the charging assembly creates an electric charge when impinged by the expanding gas located within the cavity, and a conductor in electrical communication with the charging assembly, wherein the conductor receives the electrical charge from the charging assembly. The charging system further includes a power storage unit in electrical communication with the conductor, wherein the storage unit stores the electrical charge received from the conductor.

  • Patent number: 6523534
    Abstract: An electric firing controller for a lacquer bullet gun, comprising a power circuit, a lighting circuit indicating power turned on, a closing circuit having a single triggering switch and a capacitor, and an electromagnetic control unit. By operating the single triggering switch, the electromagnetic control unit is connected with the capacitor, discharging the capacitor and causing the electromagnetic control unit to trigger firing of a single lacquer bullet. In an extension of the present invention, automatic firing of lacquer bullets is controlled by repeated charging and discharging of the capacitor, as controlled by a pulse generator and a relay. Thus precise firing of lacquer bullets with little physical effort is controlled in an inexpensive way.

  • Patent number: 6505558
    Abstract: A plurality of magazines each receive an array of pyrotechnic devices. The magazines are latched to a fire control and support assembly which automatically engages the fire control circuit to each device of each magazine. The circuit ignites all devices of all the magazines in a given serial sequence. The system, under control of an operator, when turned off, may be restarted at the beginning of a selected sequence, at the point where the last device was ignited and continue the sequence or at selected different portions of devices. Different size devices can be ignited by one circuit using different magazines all coupled to one unit. Safety features also include delay ignition after startup and sounding an alarm before any device is ignited. A CPU is enabled by a fire command signal and disabled by internal programmed instructions. The CPU is periodically enabled in a device ignition cycle by external timing signals initiated by the CPU when enabled.
