Device for detecting and locating lacerations, in particular bullet wounds or stab wounds

Abstract

The invention relates to a device (1) for detecting or locating one or more tears, in particular caused by bullet or knife strikes, the device (1) comprising: a first layer (10) of fabric (2) having a first array of conductive wires defining detection strips (B1n) elongated in a first direction; a second layer (20) of fabric (2) having a second array of conductive wires that define detection strips (B2n) elongated in a second direction and forming an angle with the first direction; a control unit (3) connected to the arrays of conductive wires and configured to locate a zone (Zn) in which a tear in the fabric (2) causes the breakage of a conductive wire of the first layer (10) and a conductive wire of the second layer (20) at the intersection of two detection strips (B1n; B2n) of the two layers (10; 20); characterized in that, on each detection strip (B1n; B2n), the array has an insulated conductive wire forming a weave that is arranged across the width and along the length of the strip (B1n; B2n). The invention relates to a garment incorporating one or more devices. The invention relates to a protection system.

         2 . The device ( 1 ) as claimed in  claim 1 , characterized in that in each detection strip (B 1   n ; B 2   n ), the insulated conductive wire ( 12 ;  22 ) forms a maze-shaped weave ( 15 ;  25 ). 
     
     
         3 . The device ( 1 ) as claimed in either one of  claims 1 and 2 , characterized in that in each array ( 11 ;  12 ), the conductive wires ( 21 ;  22 ) are arranged 2 to 4 millimeters, for example 3 millimeters, apart from one another. 
     
     
         4 . The device ( 1 ) as claimed in any one of  claims 1 to 3 , characterized in that in each detection strip (B 1   n ; B 2   n ), the weave ( 15 ;  25 ) has at least two elongated sections that extend along the length of the strip (B 1   n ; B 2   n ). 
     
     
         5 . The device ( 1 ) as claimed in any one of  claims 1 to 4 , characterized in that the control unit ( 3 ) is configured to transmit information relating to the arrays ( 11 ,  12 ) of conductive wires ( 12 ,  22 ) incorporated into the fabric ( 2 ) to a remote apparatus ( 5 ) in real time. 
     
     
         6 . The device ( 1 ) as claimed in  claim 5 , characterized in that the control unit ( 3 ) is configured to transmit information periodically, every 1 to 30 seconds, for example every 3 seconds. 
     
     
         7 . The device ( 1 ) as claimed in any one of  claims 1 to 6 , characterized in that the control unit ( 3 ) is removable from the fabric ( 2 ), such that damaged fabric ( 2 ) can be changed without having to replace the control unit ( 3 ). 
     
     
         8 . The device ( 1 ) as claimed in any one of  claims 1 to 7 , characterized in that it comprises multiple portions of fabric ( 2 ) connected to the same control unit ( 3 ). 
     
     
         9 . A garment ( 4 ), for example a jacket or t-shirt, characterized in that it incorporates one or more devices ( 1 ) as claimed in any one of  claims 1 to 8 . 
     
     
         10 . A protection system ( 100 ), characterized in that it comprises:
 one or more devices ( 1 ) as claimed in any one of  claims 1 to 8 ;   one or more garments ( 4 ) incorporating one or more devices ( 1 ); and   a remote apparatus ( 5 ) configured to receive information from the one or more devices ( 1 ) in real time.
