US 5,669,608 A · Device for locating the position of impact of a projectile

Abstract

A device for locating a position of impact of a projectile upon a planar surface of a target. The device includes a plurality of lamina-type parallel planes, fully covering the surface of the target. Each plane has at least two windings, disposed on its surface, which are arranged in zones forming a continuous conducting path. When a projectile breaks a winding, its location is rapidly sensed and reported. The pattern of wires and layers provides simple, direct compatibility of the output of the device with digital processing operations. An orthogonally situated second device locates the impact position in two dimensions and resolves possible errors in results due to the size of a projectile or a boundary hit. The device can also locate the impact of a second hit.

Dependent claims

A device for locating a position of impact of a projectile, comprising:

a plurality of pairs of windings disposed in adjacent layers each covering parallel two dimensional surfaces, each winding of a pair of windings covering adjacent zones on a respective two dimensional surface, a first of said pairs of windings defining first and second zones in a first layer, subsequent pairs of windings further dividing said first and second zones into a plurality of smaller zones,
a single winding disposed in a layer adjacent to said plurality of pairs of windings covering a common two dimensional surface, which is severed by said projectile which impacts anywhere on said parallel two dimensional surfaces, and
means connected to each of said pairs of windings and to said single winding for detecting an impact of said projectile with a winding of each pair identifying a zone on said common two dimensional surface through which said projectile passes.

A method for locating a position of impact of a projectile, comprising:

providing a first plurality of parallel layers of equal area, each layer supporting a pair of windings,
dividing a first layer into a first pair of adjacent zones,
dividing each subsequent layer into a plurality of smaller adjacent zones within a zone of a previous layer,
covering each layer with a pair of windings, a first winding of said pair of windings being disposed in alternate zones of a layer, a second winding of said pair of windings being disposed in the remaining zones of said layer,
detecting the loss of continuity in each winding of said layers in response to a projectile impact, and
detecting which of said adjacent and smaller adjacent zones of said layers are impacted by said projectile from said windings which are not continuous as a result of said projectile impact.
