Abstract
The invention relates to an apparatus for shooting a projectile at a target body, in particular a fluid projectile or solid projectile, which apparatus comprises a hand-held device for shooting the projectile, wherein the hand-held device comprises a drive for accelerating the projectile and a distance-measuring device for measuring a distance between the hand-held device and the target body. The apparatus also comprises a stored energy source for operating the drive, wherein the drive comprises a control unit, by means of which the drive can be controlled in accordance with the measured distance.
Claims21
Device for firing a projectile at a target body, comprising a hand-held unit for firing the projectile, the hand-held unit comprising a propulsion drive for accelerating the projectile and a distance measuring device for measuring a distance between the hand-held unit and the target body, the device also comprising an energy store for operating the propulsion drive, wherein the device comprises a control unit, whereby the propulsion is controllable in dependence on the distance measured, and wherein when a distance that lies below a limit distance is measured, the propulsion drive is switched off.
Method for operating a device for firing a projectile at a target body, comprising a hand-held unit for firing a projectile, and also propulsion drive for accelerating the projectile and a distance measuring device for measuring a distance between the hand-held unit and the target body, the device also comprising an energy store for operating the propulsion drive, wherein the propulsion drive comprises a control unit, the propulsion being controlled in dependence on the distance measured, and wherein when a distance that lies below a limit distance is measured, the propulsion drive is switched off.
Device for firing a projectile at a target body, comprising a hand-held unit for firing the projectile, the hand-held unit comprising a propulsion drive for accelerating the projectile and a distance measuring device for measuring a distance between the hand-held unit and the target body, the device also comprising an energy store for operating the propulsion drive, wherein the device comprises a control unit, whereby the propulsion is controllable in dependence on the distance measured, wherein the control is designed in such a way that, below a predetermined limit distance between the hand-held unit and the target body, the propulsion drive is operable in such a way that the projectile leaves the hand-held unit with lower velocity than if the predetermined limit distance is exceeded.
